Many people believe that the search engines will give more weight to your domain when considering your site for search engine rankings. Keep in mind that there should be a clear relationship between your domain name and website theme to increase your chances of ranking well in search enginesFirst, try a plural version of your key phrase. So, in the example above, you might check out the availability of top level names using "search-engine-optimizers", rather than "search-engine-optimizer
