There are probably 150 fairly active search engines being used in the US.  However, the majority of searches for content probably use only about 4 of these engines.  In fact, if you have your web site listed on approximately 15 to 20 of the most popular engines, your site has a very good chance of being found by almost anyone searching for content that appears on your pages.

Orcacom has studied the main search engines and has developed a routine that can help your website be found near the top listings of these major search engines.  For more info on this technology and how we can apply it to your website, contact our design team. 

Here is a list of some of the most popular search engines used in the United States.  These search engines receive close to 90% of the search traffic on the Internet in the United States.
