WhyYouNeedThatPerfectName.com!

&quot;What's in a name? That which we call a rose,<br> By any other name would smell as sweet&quot;<br> -Shakespeare (Romeo and Juliet) A rose perhaps but not your domain name! Welcome to the dotcom bubble! Here, any successful e-tailer should tell you that there's more to a name than just the name itself. This article serves precisely that purpose ?against the backdrop of quality domain naming strategies and styles, auctions, speculators and court conflicts, to convince you why your online endeavor needs that perfect domain name. There's no point in coming up with that absolutely fabulous idea for online selling plus a perfect site to launch from, as long as you don't have 'the' name you need. Choosing a name that will eventually contribute to your brand equity, profits, internet marketing and above all -your online credibility, shouldn't be done haphazardly. Especially, since it's so easily purchased (for a low startup capital), easily maintained and one that, if you choose, may be disposed off at a substantial amount. Intentionally or otherwise, your domain name becomes your de facto brand name, a location or an experience your visitors relate to in the long run. Even if you plan to sell it later on to prospective buyers, it is only an asset! Your challenge is to come up with that one name to funnel visitors through. Brandmeisters today seem to understand the significance of site names, especially since the emergence of a number of me-too sites. Like a Washington Post reporter put it ? &quot;feature for feature, service for service, discount for discount, even annoyance for annoyance&quot;, a number of sites may turn out to be a close match to yours. Quoting Rebecca Saunders, author of the Big Shot series, &quot;Names have to sound fresh and new even if the site duplicates one already on the net. Names should stir the imagination or otherwise gain the surfer's attention. Further site name should be as simple as possible, they should be believable, and they should be easy to pronounce, pleasing to the ear, easy to spell and therefore easy to look up on a search engine.&quot; Here's more on building your handle. The 'aha' name Domain name consultants will serve you innumerable dos and don'ts on internet domain naming ? a feat that could leave you grumbling with limited choices. Personally, your domain naming methodology need not be absolutely conventional, as long as your imagination is not slave to impractical logic and common sense. Begin with a paper, pencil and loads of patience. Consider seeking the advice of kith and kin, while you scramble ideas in your brain. Follow closely on what you ought to and ought not to consider. For example, consider characteristics, features, advantages and possibly anything that relates to your products and services. Now try to come up with a domain name that either addresses that one fundamental concept of the site, or that weds two or more key concepts in a single name. All the while, keep in mind, your site's goals, the image you wish to portray and your target audience. Don't compromise on your image-how you want your company to be perceived and it's relation to your core business memorability. Jot down your list of ideas. Then narrow it down to those names you think are most reflective of your products/services. Most importantly, determine if the domain name you like is available and that it doesn't violate any existing trademarks or copyrights. The last thing you'd want is your hard thought idea of that domain name accidentally offending a fellow netizen. Make sure that it doesn't mean something entirely different in another language and that you don't spare chance for the public to associate anything negative with it (easier said than done!). Care for the ins and outs of classic and non classic approaches in domain naming? Read on. Unless you are a domain name squatter or a start-up capitalizing on domain names - save those tongue-twisters, masqueraded phrases and unpronounceable names. Your creativity levels, thought and effort should be directed towards one that's short and sweet. Though, a long name, embedded with your major keywords, can get your site a high search engine ranking, there is no reason you should take advantage of the 67 character limit provided for domain names. Besides, you are too late now. The record of the longest domain name has been set by a Welsh village, with its registration of llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.com. Concentrate on your visitors comfort levels. Leave them no scope for confusion and no loophole to err. Give them a name they can easily guess (without having to quip over the spelling and the location of hyphens) and hopefully, they'll reciprocate with more clicks. You could always rely on those prefixes (e, i, net, web, the, my) and suffixes (world, business, company, store). The power of vowels unleashed, you'd generate a potential brand name. E.g. ebay.com, ivillage.com, pcworld.com, smallbusiness.com Lucky the business if it's creator has that perfect proper noun to lend his site a name. Atkins.com named after Dr. Atkins and Dell.com after its founder and CEO Michael Dell. A traditional business moving online could capitalize on it's established brand name. Even acronyms could yield quick domain names. Microsoft is an acronym for MICROcomputer SOFTware and so is Yahoo for Yet Another Hierarchical Officious Oracle. Targeting search engine rankings ? e.g. Yahoo that follows alphabetic classification of websites ? consider site names beginning with the digit 1 or the letter 'a'. Jeff Bezos, the creator of Amazon.com, cites this as one of his reasons for the name's choice. But for those of you driven by the age old myth ? that search engines have a liking for words that are separated by dashes- wake up! Today, when search engines focus on the site content, hyphenated names have no influence. Domain names with or without hyphens is in itself a topic for a forum. A good idea is to register both options if possible and redirect visitors to one site. Walmart.com never let go off it's original registration (wal-mart.com), even after it changed name. Now both names take you to the same site. Think of it on a broader angle. A few dollars spend to secure all possible variants of your name (with alternate extensions) will secure your visitors, otherwise likely to contribute to competitor site traffic. More - register possible names your visitors are likely to associate to your domain. The retailer Buy.com registered the domains: "10percentoffamazon.com," "10percentoffreel.com," and "10percentoffegghead.com&quot;. Proctor & Gamble is an extreme case of this blanket approach. It registered hundreds of generic domain names relating to all aspects of personal hygiene and healthcare: pimples.com, badbreath.com, underarm.com, diarrhea.com etc. They advertise only one, but use the others to bring traffic, and point all the domain names to one site. Though generic names can't be trademarked, are sources of controversy and usually unavailable (if not, costly), your prospective domain name could sound of the genre of women.com, Hotels.com, Furniture.com, Art.com and shoes.com. Nonetheless, the loss of uniqueness in generic names is a serious reason for their unpopularity among namers. Now guess why Amazon was'nt named book.com and ebay not auction.com. So, if the dictionary lets you down, do not fret to think of words that are arbitrary, previously unheard of and totally unrelated. Yahoo, Google and BlueTooth.com don't owe their origins to the thesaurus. Sometimes it pays to be whimsy! allthegoodnamesaretaken.com In just around 2 years, the number of website names registered has grown from 200 to a voluminous 125,000 per month. And as yet, already over 1.6 million domains have been registered, including the subtitle above! Chances of you finding a 3 character .com domain name unregistered (not on sale!), are thin? very thin. Here's the good news. Everyday, around 20,000 domain names expire and get deleted. In addition to the generic domain extensions such as .com, .net, etc. there are approximately 250 different international domains each with their own two-letter country code extension. Speculations of new TLD (Top Level Domain) names include .firm, .store, .arts, .info, .nom, .biz, .pro, .aero, .coop, .museum and .name. So, don't settle for the first domain name you think of! Although the supply of domain names is diminishing daily, it's better to expend more thought at the beginning and save money later. Don't let the gold rush skate your decision (and later leave you to regret over an unmarketable name). Then again, don't sit just hatching ideas. Even as you read this, someone halfway across the globe might be beating you to your choice! Some are just registered by entrepreneurial opportunists hoping to make a fast buck by selling it on. If your choice is taken, the easiest, cheapest and most reliable solution would be to register another name. Did you know that the auction site eBay.com was the second choice of it's creator after his initial pick EchoBay.com was taken? A good name is a legal name! Nonetheless, if you own a successful site, that just can't do without that colonized ideal name, you better ensure your pockets are deep because the owner at the other end knows that there's nothing quite like the commercial value of a domain name. The highest publicly known sale of domain name was the sale of Business.com for $7,500,000 to eCompanies, a business incubator. Domain names have been turned into a marketing bargain with its parking capability. A business can register or buy a name for later use. And there are sites that do nothing but park potential names mostly sold for fire-sale prices later on! A Belgian doctor, Dr. Lieven P. Van Neste owns well over 200,000 domain names. It's a fine pursuit, if you care to keep your distance from brand infringement. In the past, speculators have faced legal charges on trademark violations from the bigwigs (including Microsoft) for having registered microsoftwindows.com, microsoftoffice.com, AirborneExpress.com, CitibankMasterCard.com, HewlettPackardss.com, and Wall-Mart.com. Domain name conflicts that grabbed headlines - Yahoo vs. "yahooka.com" (a marijuana site), Nissan Motors vs. Nissan Computer Corporation. One that caught my personal appeal - Archie Comics company's trademark driven domain dispute with Veronica.org, a website set up by a loving dad in honor of his 2-year-old daughter Veronica! From McDonalds to MTV, a lot of press on online brand infringement ( the hijack of popular brand names) has filled the air. Even as I write this, Google Inc. is being challenged the right to use the name "Froogle" for its online shopping service (a New York based carpenter owns Froogles.com - web shopping site). Each year, about 250,000 cases are decided by the US federal courts. If you have no time to sort it out the good old fashion, you should consider devising a strategic approach for domain naming, reflected in sound corporate policy and executed with effective management. Toady it's a topic of senior boardroom meetings where competent professionals are assigned to conduct name searches (a less costly venture compared to the possible consequences of dealing with a complaint of infringement.) Take lessons from corporate folklore on the long term effects of a carelessly chosen domain name. People who learnt things the hard way include Art-U-Frame.com that paid $450,000 to acquire the name art.com. The crux Your domain name is more than a ubiquity. You have no other billboard or bypass to your site. Statistics prove that direct navigation or guessed URLs account for majority of the traffic to a site (64.43%), much more than the search engines can bring (35.55%). Eat, drink and sleep on your idea before you move to register that killer name. Don't hassle, thinking there are nodomainnamesleft.com (that's taken too!). Your share of homework should save you a lot of misery down the road. Besides, if you can't trademark your design scheme, product idea and marketing strategy, here's something you can. Your domain name is perhaps the only thing that you can own on the Internet. Remember, there's always more to a name than just the name itself! Happy naming!

Good Domain Names Make Your Dreams Memorable

"What was the name of that website? It was good. It has something to do with..." Is your web site like many others? Domain names always on the tip of a visitor's tongue, but not quite memorable enough? Your choice of domain name needs to be easy to remember, as well as focused enough that your visitor will know right away what your site is about. A Few Rules Some rules do apply when deciding on a domain name: <li>Domain names must be at least two characters long but no more than 63 characters, not counting the TLD.</li> <li>You can use any combination of letters, numbers, or hyphens, but you can't use a hyphen as the first or last character.</li> <li>Domain names are not case-sensitive, so my-home-based-business-advisor.com is the same as My-Home-Based-Business-Advisor.com.</li> Choosing A Domain Name Choosing good domain names is almost as important as choosing your actual business (see our Startup Ideas page). There are many different schools of thought when it comes to picking good domain names. Some say to choose a short, concise name. Some like numbers in the name, some don't. Hyphens and underscores -- as opposed to words all running together -- are another debated topic. It's mostly a matter of easier reading for your human visitors. Which do you find easier to read? myhomebasedbusinessadvisor my_home_based_business_advisor my-home-based-business-advisor Generally, the hyphens between words make domain names easier to read for most people. While search engines don't rank domain names, a keyword-rich name will let your visitors know what your web site is about before they get there. This makes them more comfortable because they know what they're getting in advance. Also, when you get other sites to link to yours, that link is usually based on your domain name. This means that your main keyphrase (which you used as your domain name) will be the actual anchor text and search engines do give additional ranking for that. Domain names play a major role in making your dream memorable to the world. Take the time to do it right and your dream of a home-based business will be seen all over the world!

Tips and Tricks To Getting Top Money for your Domain Names

Would you like to be that lucky person who sells their domain for thousands or even a million dollars? It IS possible to find quality domains and resell them for huge amounts of money. The time is ripe for acquiring top domains and selling them. Now that the Internet Boom is behind us, valuable names expire everyday. The best way to find these domains is to use services on the Internet such as DomainsBot to weed out the bad names. Or just check out Hot Lists on sites like Namewinner or Pool. So what makes a "good" domain name? Usually short, single word domains and 2-3 letter .coms, .nets, and .orgs are the best. The more specific the better. These can be hard to come by but when you find them, you can almost guarantee that you can make good money from them. Once you have purchased a nice domain name, get a good appraisal of the name to get an idea of the possible worth (see AppraisalBlast.com). In order to sell your newly appraised name, you have to find a buyer. Here are your basic options for selling your domain name in a nutshell: 1. Sell it on Ebay This is the easiest and quickest way to sell your domain name. There are several tricks to landing a good sale at Ebay. One is, start your price low. People want a bargain. Once you have received an initial bid, it will draw peoples attention to your name and create more bids. You may want to set a reserve price if you want to make sure you get X amount of dollars. When selling your domain on Ebay, make sure your domain name is in the title of the description. Also, include an appraisal to show to possible buyers the value of the domain. Keep your description short, clean, and really emphasize how important and rare your domain is. For example, if your domain is 3 letters and ends in "I", stress how most 3 letter domains that are highly valuable end in "I" because it usually stands for "Incorporated". If it ends in "E" it could stand for "Enterprise". A little bit of marketing saavy can go a long way. I once sold the domain 0pp.com for over $200. It even has a number in it making it worth very little. But I emphasize its possible uses and potential. Also, spend the extra $1 for the Bold Listing and make sure your auction ends on a Sunday afternoon or evening. This is when most people are browsing Ebay. It will make a big difference. 2. Sell it on Domain Sites The only sites you should even consider putting your name up for sale is on ebay.com, Afternic, or Sedo. These are the most popular and where some huge sales have taken place. The only downside is that there are high numbers of domains already for sale and usually the site will get a commission of something around 10%. There also may be a small fee to join. Appraisal Blast charges a minimal fee but no commission. Your domain will get more exposure there just because there aren't hundreds of domains for sale. You may also have luck selling it on forums such as DomainState. The prices of sales there seem to be lower. 3. Contact Large Businesses with Deep Pockets This approach takes some time and patience. Let's say you have acquired a great domain name that would work great for any business in the field of the stock market. You may want to locate some of the bigger sites or businesses and make an offer to sell your domain name. Make sure the name you own doens't have any elements that are already trademarked because you may be forced to give up the name. You may want to go on the Internet and look up current websites that deal with stocks and find ones that don't have the greatest domain names. Make offers to these sites stating how your domain is much better and will HELP them. If you get a company to bite, the rewards are usually very generous! In summary, selling domains for high amounts of cash depends on two key elements. First you must have a quality domain, one that doesn't have numbers or isn't too long. It must be clear and easily recognizable. ".com" is the best, but even domains such as the ".us" are gaining popularity. The second key is Marketing, Marketing, Marketing! I can't stress that enough. You have to create a good reason for someone to buy your domain. How can THEY benefit from it. When these two steps are fulfilled, a sale is almost guaranteed!

Why El Cheapo Domains Will Cost You Money

You want your own online business? Good because it's one of the most fun things you can do with your spare time and can be very profitable. Remember that just because it's an online business doesn't mean that you should treat it with any less professionalism or seriousness than you do your daytime job. Why? Simply because when you run an online business it's a serious business. Well it should be taken seriously if you want to make serious money. One of the most important aspects of any online business is the domain name. This is where the vast majority of new online entrepreneurs make their first big mistake - they choose one of those free domain name providers to represent their business online. This is a critical mistake. Let's say you're starting a computer repair business. Which one of the following domains looks better: 'www.computerfixer.com' or; 'computerfixer.freehosting.com' The truth of the matter is that computerfixer.com is a top level domain and computerfixer.freehosting.com is a sub-domain. These free domain providers would have you believe that their cheapo subdomain is as good as a top level domain - this simply isn't so. Online shoppers expect your online business to be located on a top level domain. If they find your website on one of these cheap or free domain services you've just lost 50% of your potential customers. They'll click back and look at the next search result in Google, Yahoo or MSN. Free domains make you look cheap, show that you don't want to invest in your business, that you don't take your customers seriously, look terrible on business cards and make you look like an amateur. There aren't any benefits to cutting corners on your domain name. A domain name costs, at most, $15 per year. That's 4 cents per day. If your business can't afford this then you really shouldn't be running an online business at all.

Domain Name Registration and Privacy

The internet is a wonderful thing, except for a few small details. When you register your first domain name, you get your introduction to one of them. There's a lot of information they want. Your name, your email address, your physical address, your phone number. For each of 4 separate categories, and the Registrant, Admin and Technical categories are publicly available (for almost all TLDs - Top Level Domains, with the possible exception of .ws - Western Samoa). Email addresses, which must be valid, phone numbers and physical addresses which also must be valid. I personally think it's both absurd and dangerous to make this information so easily available. Once again the right to privacy of law-abiding individuals is being abridged supposedly to help catch lawbreakers. Since this information would be provided under a court order, making it publicly available just invites abuse. Spammers, scammers, stalkers and the idle whacko can easily get this information. And it's a nice start on identity theft, too. However, for most people, the most likely result is an increase in the amount of spam you get. But, much worse can and has happened. So what solutions are there? Basically there two ways to protect your privacy if you are a private individual without access to a legal entity such as a company to own the domain name (note that if it is a company, you must provide accurate information. This only moves the problem to a slightly less personal level). First you could lie. No, that's not one of the ways. Unwise and illegal too, and you are a law-abiding type, right? So, first, a proxy registration is one alternative. Essentially you make a binding legal agreement with a company which will register the domain name as if they owned it and then provide their own information to meet the requirements. For each domain, they will set-up a special email which they will monitor and forward to you, usually after spam filtering, if you want them to. They, of course, retain your data and will also monitor physical mail. You will be notified of first class mail which appears to or could be legal documents or if registered or couriered mail arrives. They will, for a fee, ship such to you, if you agree and pay. Generally such items would be sent by courier. Phone callers will be directed to use the email or physical address shown in the WhoIs record Of course, under subpoena or other specified conditions they will provide your details. You will have full rights as owner - as long as you behave and don't violate the agreement. The other alternative, usually called "private registration", is a little different. Here your name would still appear as registrant. You would provide the names of the admin and technical contacts. But the address, email and phone number would be provided and monitored by the organization handling the private registration in essentially the same manner as a proxy registration. Thus with this alternative you remain in full legal control of your domain name since it is registered in your name rather than the name of a proxy. On the face of it this second alternative sounds better, but your name is hanging out there on view and you may have valid reasons for not wanting that (perhaps the company you work for takes a dim view of moonlighting, or you have had a stalking problem or are doing something perfectly legitimate but don't want your name linked to it).In that case, a proxy registration is the only real alternative. In case you're thinking you can hide out and do whatever sort of bad stuff behind a proxy or private registration, don't even dream about it. These outfits take it very personally if you misbehave and the legal agreements spell it out. If you decide to pursue a proxy or private registration, make very sure that you are working with a legitimate company with a track record. A domain name can be a very valuable possession. Both your registrar and, if it's a separate organization, the entity that does the proxy or private registration must be quality, legitimate outfits. Registrars offering extremely low prices which are way out of line with the going rates - unless it's a special - just might be after your credit card and identity. Also, this time, actually read the agreement and TOS so you do know what you're doing and what could happen under what circumstances. Wondering why I'm writing about this? Well, it's because I'm getting more and more spam and I started doing some research on possible solutions. And I figured, I wan't the only one looking to do something about the problem. And then, I discovered that some registrars will provide free proxy or private registration with your domain name purchase. So think about it and do some checking before you buy a domain name. Your privacy is a precious possession. Copyright 2005 Richard Keir Richard teaches, trains and consults, on and off-line. And he writes a lot.

Know How DNS Works

Domain name Servers (DNS) are an important but invisible part of the internet, and form one of the largest databases on it. Each machine on an internet is assigned a unique address, called an IP address, which is 32 bit number and is expressed as 4 octets. The method user to represent these IP addresses is known as dotted decimal Notation". A typical address looks like this: 199.249.150.4 It is very difficult to keep in mind the IP addresses of all the websites we visit daily, because it's not easy to remember strings of numbers. However, we do remember words. This is where domain names come into the picture. If you want to connect to a particular site, you need to know its IP address but do need to know its URL. The DNS gets the mappings of the IP addresses and the corresponding names. Names and numbers DNS converts the machine names (such as www.xyz.com) to IP addresses (such as 199.249.150.9). Basically, it translates from a name to an address and from an address to a name. The mapping from the IP address to the machine name is called reverse mapping. When you type http://www.xyz.com into your browser, the browser first needs to get the IP address of www.xyz.com. The machine uses a directory service to look up IP addresses and this service is called DNS. When you type www.xyz.com your machines firsts contacts a DNS server, asking it to find the IP address for www.xyz.com. This DNS server might then contact other DNS servers on the internet. DNS is therefore is considered as the global network of servers. The great advantage of DNS is that no organization is responsible for updating it. It is what is known as distributed database. The three letter codes A DNS server is just a computer that's running the DNS software. The most popular DNS software is BIND (Berkeley Internet Name Domain) DNS is hierarchical, tree-structured system. The top is donated by'.'. And is known as the root of the system. Below the root there are seven immediate sub domain nodes and these are 'com', 'org', 'gov', 'mil', 'net', 'edu', 'Int', etc. DNS consists of two components <li>Nameserver <li>Resolver Nameserver: This performs the task of looking up the names. Usually, there is one nameserver for a cluster of machines. If the nameserver does not contain the requested information, it will contact another nameserver. But it is not required for every server to know how to contact every other server. Every nameserver will know how to contact the root nameserver, and this in turn will know the location of every authoritative nameserver for all the second level domains. Resolver: This runs on a client machine to initiate DNS lookups. It contains a list of nameservers to use. As we have read, the function of each of these nameservers is to resolve name queries. There are three types of nameservers-primary nameserver, secondary nameserver, and caching nameserver. The secondary nameservers are configured for backup purposes. Caching nameservers only resolve name queries but do not maintain any DNS database files. It is important to note here that any change to primary nameservers needs to be propagated to secondary nameservers. This is because primary nameservers own the database records. The changes are propagated via a 'zone transfer'. HOW 'CACHING"WORKS DNS uses principle of 'caching' for its operation. When a nameservers receives Information about a mapping, it caches this information .further queries for the same mapping will use this cached result, thereby reducing the search cost. The nameservers don't cache forever. The caching has a component called time to live (TTL) and the TTL determines how long a server will cache a piece of information. So when the nameservers caches receive an IP address, it receives the TTL with it. The nameserver caches the IP address for the period of time then discards it. When a process needs to determine an IP address given a DNS address, it calls upon the local host to resolve the address. This can be done in variety of ways: Table look up. On UNIX hosts, the table is /etc/hosts. The process communicates with a local nameservers. This is named on a UNIX system. By sending a massage to the remote system that is identified from the information in the file/etc/resolve.conf. When a nameserver receives a query for a domain that is does not serve, it may send back a referral to the client by specifying better nameservers. Typically operate in the recursive manner wherein any DNS server passes requests it cannot handle to higher level server and so on, until either the request can be handled or until the root of the DNS name space is reached. The nameservers contain pointers to other nameserver with the help of which it is possible to traverse the entire domain naming hierarchy. A host with the initial nameserver addresses has to be configured. After this, it is able to use DNS protocols to locate the nameserver responsible for any part or the DNS naming hierarchy. Thus when a nameserver receives a request, it can do one of the following: It can answer the request with an IP address. This method is called iterative. In this, the client simply asks the server to resolve a domain name. The server accesses its database, finds its IP address and sends that back. If the server does not find the address, it sends back an error ;DNS not found'). Contact another nameserver and try to find the IP address for the requested name. Send back a referral to the client specifying the IP address of better nameservers. A popular user interface, called 'nslookup'is available on the UNIX system. With this, you can perform any DNS function. This program also displays the result to the user. Using is nslookup, you can obtain a listing of all the hosts in a zone. In order to do this, you first need to identify the nameserver for the zone. The threats that are associated with the DNS are due to the lack of integrity and authenticity checking of the data held within the DNS. Also, other protocols can use host names as an access control mechanism. The internet engineering task force (IETF) has come up with DNS security (DNSSEC) extensions to DNS protocol. The main objective to DNSSEC is to provide authentication and integrity to the DNS. These are provided through the use of cryptographic' About The Author Pawan Bangar,<br> Technical Director,<br> Birbals, Ebirbals, SeoBirbals, Hbirbals<br> India.

Domain Name Forwarding and Search Engines

You own a single site, but several domains - perhaps you wanted to make sure that even if your customers misspelled your domain name they'd get to your site, or perhaps you'd like to have a specific domain name direct to a page deep within your site - whatever the case, there are some important considerations surrounding multiple domain names routing to a single site and search engine submission. Search engines like Google and Yahoo won't always wait around for you to submit a site - Googlebot and Yahoo Slurp (which you may recognize from your server logs if your site has been up for a few weeks) are constantly running across new domain names to index. It's a good thing - unless your domain names are being forwarded incorrectly. What constitutes and incorrect forward? Many major domain name registrars offer a "Domain Name Forwarding" feature which, while it may be the easiest way to forward your domain, can cause some real problems when search engine spiders like Googlebot or Yahoo Slurp visit your site. Here's what happens: <li>The search engine spider pulls your domain name (usually from http://www.whois.sc/ )</li> <li>The spider visits your website, using the domain name forwarded through your domain registrar</li> <li>Your domain registrar is using a Temporary Redirect (most likely because it's assumed that you'll point the domain name to a new hosting account sooner or later), frames, or other incorrect forwarding method</li> <li>The spider indexes your site</li> But what went wrong? Your domain name registrar did its job, and sent the spider to your actual site when it visited the domain name you registered. The spider did its job and read the content of the page or pages it found, and then incorporated them into the search engine index. Everything's copacetic, right? When the search engine spider read the page, it associated it with your alternate domain name, the one that was supposed to be forwarding to your primary domain name. This means that the search engine has effectively tracked down what it will quickly identify as duplicate content - and, after years of dealing with sites trying to sell Viagra on the sly by duplicating their content across hundreds of pages, today's search engines will respond to duplicate content with a drop in your ranking. Given enough time, you may find your site has been banned from the search engine index. What's the solution? Your domain names need to be routed from the domain name registrar to a hosting account - from the hosting account (and this varies - consult your technical support provider for the account) you'll need to set a Permanent Redirect to your main site. A Permanent Redirect is logged as a code '301' (thence, it is often referred to as a '301 Permanent Redirect') - if you have multiple domain names which you wish to direct to a single site, it may be especially useful for you to consider a website hosting account which offers multiple add-on domains and subdomains to accommodate all the domain names you'll need to forward.
