Only submit ONE PAGE
Many people believe that they should submit all of the pages (or multiple pages) from their website. DON'T DO IT. You will likely get banned from the search engines.
Only submit your home page, and follow the submission rules.
If you have multiple pages on your site that relate to different subjects, make sure they are in their own directories and make sure they are really on different subjects.
Don't try to spam the engines with multiple pages in the hopes of getting more keyword results. It just won't work, and will likely backfire.
