This will return every page of your site that is indexed with a particular search engine. Links have become even more important recently as major search engines have begun to use the links to a page or a site as one of the factors used in determining which pages will appear higher in a list of matches. Pages and sites with lots of links from other sites with related content are considered important when calculating the ranking for a particular query. One nice benefit of determining who links to your site is if you have changed the address of a page on your site, or if you changed your directory structure, you can find out what pages have hyperlinks to the old addresses. Then you can contact the webmasters of those pages and request that they change to the new addresses, so you don't lose the link.
Every match is equal.
So don't worry about the order of the rank. And this is one important instance where the person submitting the query may well want to see all the results, rather than being limited to just the first 200. Site submissions to these categories can no longer be submitted for free. The prior 60-90 day wait through standard submission was costly. You don't want to wait any longer to begin making money.
