Adding your new site to the major directories is a key task if you want to build traffic and page ranking. While the list below is not exhaustive, it will get you well underway in your directory listings.
A few points to keep in mind as
you add your site to these directories:
• Directories are not search engines. Directories are edited and managed by human beings, whereas search engines are programs that troll the web looking for pages. Your site might be recommended to a directory by one of the site editors, or a very enthusiastic fan of your site, but most likely you will have to introduce yourself if you want to make a directory's list.
• Be sure the directory is indexed in the major search engines. A quick search at Google, Yahoo & MSN will do.
• Be sure the directory is not banned by Google. You probably won't get flagged by Google if you are listed there, but the risk is too great - there are hundreds of other places for your link.
• Page Rank isn't everything. Don't skip sites just because they have a low page rank. While Page Rank is extremely helpful, it changes over time. A directory with a PR of 3 this month could jump to 6 next month. Also, take note of the Page Rank of the specific page of the directory your site will be listed on. Just like it says, Page Rank is for pages, not for sites. A directory could have a PR of 7, but the page your link appears on might be a humble 1.
• Directories are not overnight traffic. Look around the submission guidelines and to see how long the editors will take to review your site. Free sites can take up to four months to get approved.
• Go after the older directories first. Google values a site's age, and you should to.
• Review the directory's guidelines and don't abuse them. Don't submit your site every week. Don't add an unrelated site to a niche directory. Don't try to trick the editors into adding your site to more than one category if that goes against the guidelines.
Now that you know the basics of evaluating and submitting to directories, here's a short list of the top sites:
