You can add your URL to some of the most poplar search engines. There is also a brief description of what that engine looks for in determining ranking.

Add Your URL to Infoseek
Infoseek uses META tags to describe how a page should be classified this is the easiest add process, but that results in a lot of people using the resource. To increase your positioning you need to use all META tags, ALT tags, all page text (that is actually likely to be seen by a visitor),be sure the correct words appear in these areas in the correct balance and frequency. And, yes -- the use of capital letters (case sensitivity) is important.

Add Your URL to Northern Light
Northern Light is a very nice engine that automatically creates "folders" for common site types, such as commercial, private,or specific URL's if many of the results are from that site. This is a great resource, and one that I think will increase in usage. Northern Light is similar to InfoSeek, except that the TITLE receives significant weight.

Add Your URL to Yahoo
Yahoo is not a Search Engine but rather a searchable directory. The keywords are restricted to their directory topics and the pages are accepted or declined by a real person that reviews your page for relevance to your desired category. TIP: Add at the regional level and (if your topic has global appeal) they will add it globally. Trying to add it globally will take forever. Try to place it exactly where you want it, and prey that the Yahoo's agree.

Add Your URL to Lycos
Lycos is another simple search engine that uses META tags and content. They will not allow special characters in some areas (such as META tags),so avoid ?, =, and $. Lycos is somewhere between InfoSeek and Northern Light in their use of META tags, except they do not care about case sensitivity.

Add Your URL to AltaVista
AltaVista is another example of a search engine that uses META tags and content. Very similar to the above except that it will ignore comments and is also not case sensitive.

Add Your URL to Excite
Excite is an example of a search engine that does NOT use META tags. It specifically ignores all META tags and instead extracts text (seemingly at random) from the body of the page. Beware: it has been known to use java scripts as text, but apparently tries to use sentences from the page as search engine keywords. As a result, it is vital that major keywords be distributed around the page. Use Key words in very short sentences whenever possible.

Add Your URL to HotBot
HotBot is another example of a search engine that uses META tags and content. It is very similar to InfoSeek except in case sensitivity.

Add Your URL to WebCrawler
WebCrawler is another example of a search engine that uses META tags and content. It is similar to Northern Light except it emphasizes KEYWORDS instead of TITLE.

CNET Search.Com Add Your URL to CNET
Similar to Yahoo in that you need to identify the area where your listing should appear then ADD URL from that page.
