Quote: Eliminate Navigation Barriers
Search-engine spiders prefer easy-to-navigate sites as much as your end users, with all seeking to understand where to find information on your site. Providing clear pathways to all the pages on your site is essential for "findability."
Create an XML site map for spiders and a user-friendly site map for your visitors. XML site maps provide guidance to spiders in regards to what pages exist on a site, and how often you update them. They are becoming the standard for crawl submissions. User-friendly site maps provide additional navigation links throughout your site for users and spiders alike.
Check Your Code
If the spiders can't understand your code, they will miss your entire page around a few "simple errors." Is your code valid? Validate your code often through tools like those available from W3C.
Check your robots.txt file to make sure that it's not blocking spiders for any content that you want indexed. It's surprising, but companies have blocked spiders from their entire sites with a misplaced backslash or other errors. Don't let this be you.
