Google's search algorithms might be shrouded in mystery, but making sure the search engine giant is indexing your Web site isn't. Aside from your Web browser and an Internet connection, the only thing you need to verify Google is indexing your Web site is Google.
To see whether or not Google is indexing your Web site so it appears in Web search results, point your Web browser to the Google Web site and search for info:<your web site> -- for example, if I want to verify Google is indexing The Mac Observer, I'd enter info:www.macovserver.com.
Google will tell you if it is indexing your Web site, and also generate links to show what cache info it has for your site, which Web sites link to yours, and more.
If Google isn't indexing your Web site, that's usually an easy fix. Just submit your URL to Google and let their servers do the rest.
