Some tricks you'll never hear about! 

Post your site to Open Directory Project, as a lot of search sites are using their raw data! Check this out:................. http://dmoz.org/Computers/Internet/WWW/Searching_the_Web/Directories/Open_Directory_Project/Sites_Using_ODP_Data/

Open Directory requires a good central theme. If you have a community web site make sure you identify your location as editors will at least try to place it in a locality if they see a city or town plus state address! Out of construction signs tell editors like myself you are dumb enough to waste our time, so we delete you on contact. Don't be stupid enough to spam, we log every entry! Make sure you have CONTENT, 5 hyperlinks and a banner tell me you have a weak site.

If you belong to a community site and are getting nowhere with submissions (Sites like Geocities for example get bounced by many search engines because of porn and spamming). Get out and set up a site at a less known community site or better yet get a site that you see being posted often by search engines perhaps like Virtual Avenue for example. (if you don't want a domain)

Getting a domain your own site for $30 for 2 years is an even better solution and insures listings in more search engines an directories than community sites ( some search engines and directories (Yahoo for example) only will take domain sites). Many of your larger search engines hardly even post community sites.

Put your "web site title" somewhere into your web page text. That way your title will always be picked up! For example my site is called "Chemical Laughter", I might say "chemical laughter is the ......:" (put it in your meta tags too.)! You'll find your site faster and so will others looking for your site!

Make sure your site title is also in your meta tags.... both description and keywords if possible. Many search engines search their databases differently and may not find your title unless you add these in.

Don't spam engines with multiple page entries, as they are eventually picked up and the webmaster will remove your site and every site associated with you. This is more serious now than ever!

Alta Vista and Google goe through all of your web pages and lists them. Make sure you have links going back and forth to each page. 

Be sure to use the statement <frames> and <no frames> on your website if it contains frames!

Cut down on graphics on your index or homepage and add more text. . This is important as Excite looks for around 100words (2-3 paragraphs of text) to help determine your site contents. Doing this will enable your site to get listed through-out the Excite's family of search engines.

Make sure you have posted sites to like MSN, even if you didn't get listed you may have been picked up by their spiders which use Inktomi.com...to add your listing to the Inktomi's big database!
