搜索引擎优化材料提供一些重要的规则，以选择合适的域名 。 While the availability of domains which follow all of these rules may have become limited, try to follow as many of these rules as possible.虽然域，按照本规则的所有情况可能已成为有限的，尝试按照尽可能这些规则很多。

• Consider naming your company and registering a domain name starting with the digit 1.考虑命名您的公司和注册域名与数字1开始。 Better still, choose a name starting with "1st".更好的是，选择一个名称以“1”开始。 Why?为什么？ When people create directories of web sites, they have to decide how they are going to classify those web sites.当人们创造的网站目录，他们必须决定它们将如何进行分类的网站。 One way to classify web sites is to list them on the basis of how "good" they are.一种方法是分类网站列出的基础上他们如何“好”，他们是。 Another way is to simply list them in chronological order (and sometimes in reverse chronological order) based on the dates the sites were submitted.另一种方法是简单地按时间顺序列出（有时是相反的时间顺序它们）的基础上的网站提交日期。

  The other, and far more popular classification system is alphabetic.另外，和更流行的分类系统是字母。 Now, the first character in the ASCII chart which can be used as the first character in a domain name is the digit 0.现在， 域名的第一个字符的ASCII图表可以是一个字符作为第一个是数字0。 The next character is the digit 1.下一个字符是数字1。

  Normally, you wouldn't want to start a domain name with the digit 0 since it might send all the wrong signals to your customers.通常，你不会想启动数字0与一个域名 ，因为它可能把所有的错误信号，以您的客户。 For instance, if we had named our domain 0SearchRanking.com, it would be telling our customers that we cannot get them any search engine rankings at all!举例来说，如果我们有我们的域名0SearchRanking.com命名，它会告诉我们的客户，我们不能让他们在任何搜索引擎排名所有！ Hence, unless you really have a good reason for doing so, you should avoid using domain name s starting with the digit 0.因此，除非你真的有这样做是有原因的，你应该避免使用域名卖0开头的数字。

  Instead name your domains starting with the digit 1.相反的名字您的域名与数字1开始。 More specifically, name your domains starting with "1st".更具体地说，您的域的名称与“1”开始。 This will ensure that you get a high alphabetical placement in those directories which classify sites alphabetically.这将确保你获得较高的这些目录中的分类网站按字母顺序按字母顺序排列的位置。 Furthermore, depending on the industry in which your company operates, it may also send the right message across to your customers - it indicates that you are the first company to consider in your industry.此外，在行业中的公司经营的不同，它也可能带给您的客户提供正确的信息 - 它表明你是第一家考虑在你的行业。

  And guess what - the mother of all directories - Yahoo!你猜怎么了 - 所有目录的母亲 - 雅虎！ - lists web sites alphabetically based on the Title that had been submitted. - 按字母顺序列出了网站上已经提交的标题为基础。 Yahoo!雅虎！ wants the Title to be the official name of the site.希望标题是网站的正式名称。 This implies that sites which start with the digit 1 will be placed at or near the top of a category.这意味着，该网站与数字1开始将在或接近顶部放置一个类别。 Assuming that you can get your site listed in Yahoo!, just look at what a top ranking in one of the categories in Yahoo!'s directory can do for the popularity of your site!假设你可以让您的网站在Yahoo！列出来，看看在对雅虎的类别之一一流！的目录可以为您网站的知名度！

  Furthermore, a small caveat here.此外，这里一个小警告。 If you are going to name a domain starting with "1st", also register the domain which starts with "ist".如果你要开始一个域的名称与“第一”，也与注册的域名是“北京时间”开头。 Then, have the domain containing the vowel "i" redirect visitors to the domain containing the digit 1.然后，有域包含元音“i”的重定向用户到域包含数字1。 This is because people will often type in 'ist' when they mean '1st' and vice-versa.这是因为人们通常会输入'北京时间'时，他们指的'1次'，反之亦然。 Also, for every email alias that you create for the domain containing "1st " (like sales@1stseo.com), you should create the corresponding email alias for the domain containing "ist" (like sales@istseo.com).另外，对于每一封电子邮件别名，您对包含域创造“第一”（如sales@1stseo.com），你应该创建为包含“北京时间”像sales@istseo.com（）域相应的电子邮件别名。

  Also, this strategy of registering domains starting with '1st' is mainly applicable if yours is a somewhat new company.此外，本次注册域名与'1'开始的策略是主要适用如果您是一家有些新公司。 If you own a well established concern with a well known domain, you simply cannot change your company name and your domain in a hurry because you will confuse your existing customers.如果你拥有一个知名的域名完善的关注，你根本就不会改变您的公司名称和您很着急，因为你会迷惑你的现有客户域。

• Don't want to start your domain name with "1st"?不要想开始你的域名与“第一”？ Consider starting it with "A", "B" or "C".开始考虑以“A”了，“乙”或“C”。 Although domains starting with A, B or C will be listed after those starting with the 10 digits, you can still get a pretty high alphabetical placement with A, B or C.虽然域与A开始，B或C会后与10位出发的上市，你仍然可以得到一个具有相当高的字母顺序排列的位置，B或C

• Try to register a domain which contains a popular keyword applicable for your industry.尝试注册一个域名，其中载有流行的关键字为你的行业适用。 This will help your customers remember your domain name better.这将帮助客户更好地记住你的域名 。 Furthermore, for searches conducted in Yahoo!, a higher ranking will be given to those web sites which contain the keywords in the title.此外，在雅虎进行搜索！，较高的排名将给予这些网站包含在标题中的关键字。

  And according to Yahoo!'s instructions, the Title should always be the official name of the site.而根据雅虎的指示，标题应始终是该网站的正式名称。 Thus, if the domain name contains a keyword, you will be able to include the keyword in the Title which will improve your ranking in Yahoo!.因此，如果域名中包含关键字，你将能够在包括标题关键字将改善您的排名在雅虎！。 As a minor side-benefit, this can also help to increase the ranking of your web site in some search engines.作为一个小的副作用的利益，这也有助于提高你在一些搜索引擎网站的排名。 Hence, in an ideal case, you should register a domain of the form 1st[keyword].com (without the brackets of course).因此，在一个理想的情况下，你应该注册一个域名的形式第一[关键字]。未经当然括号的COM（）。

• Try to avoid using domains that contain '2' for "To', '4' for 'For', 'u' for 'You' and so on even if they seem to make your domain sound 'cool'. Your customers will easily get confused if you do so. However, if you must register such a domain, register the expanded form of the domain as well, ie if you are registering greatthings2do.com, also register greatthingstodo.com.尽量避免使用域包含'2'“为了'，'4'为'为'，'ü'为'你'等，即使他们似乎使您的域名的声音'酷'。您的客户会很容易弄错了，如果你这样做。然而，如果您必须注册这样的域名，注册的域名形式以及扩大，也就是说，如果你是注册greatthings2do.com，还注册greatthingstodo.com。
• Don't register a domain containing the digit 0 in it, unless it is going to be part of a recognizable word (like 1000 or 2000).不要注册的域名包含在它的数字0，除非它将会成为一个公认的字（如1000或2000部分）。 This is because the digit 0 is often confused with the vowel O. If you feel that you must register a domain with the digit 0, make sure that you also register the corresponding domain containing the vowel O.这是因为数字0经常与元音澳混淆如果你觉得你必须登记，数字0一域，请确保您还注册了相应的域名包含的元音澳
• Always use ".com".始终使用“。com”。 If yours is a serious business site, avoid using domains ending in "nu" or "to".如果你是一个严重的营业场所，避免使用域的“女”或“终结”。 Your business will have little credibility if you do so.您的企业就没有什么可信度，如果你这样做。 You can consider registering a ".net" domain, but since most people are familiar with ".com", it is better to stick to convention.你可以考虑注册一个“。网”域名，但由于大多数人都以“熟悉。com”，最好是坚持公约。

• Should you or should you not use hyphens in your domain?如果你或你不应该在你的域名使用连字符？ Well, the jury is out on the question.那么，陪审团就这一问题。 While some Internet marketers will tell you that domains containing hyphens are difficult to remember, spell and pronounce, others will state that domains containing hyphens are, in fact, easy to remember, spell and pronounce.尽管一些互联网营销会告诉你，含有连字符的域名难记，拼写和发音，其他人都注明含有连字符域，其实，便于记忆，拼写和发音。 Go figure.转到数字。

  Personally, I would feel that whether or not hyphens are helpful has to be determined on a case by case basis.就个人而言，我会觉得，不管有没有连字符，有助于将于按个别情况来判断。 However, if you register a domain containing hyphens, make sure that you also register the corresponding domain without the hyphens.但是，如果您注册一个域名含有连字符，请确保您还没有注册相应的域名连字符。 Once you do that, you can simply redirect visitors from the domain without the hyphens to the domain with the hyphens.一旦你这样做，你可以简单地从域中重定向旅客没有到与连字符的域名连字符。
