"Search Engine Saturation" was not a term I had heard previously so this thread caught my attention. A quick search seemed to lead me to think that it refers to how many of your site's pages are indexed versus how many pages an competitor's site has. Is this right? Assuming I've understood the term correctly, it should be a simple task of uploading more pages than your competitor and then ensuring they get indexed using sitemaps, backlinks, good site navigation etc. Jon
As with most issues in Google, the depth and frequency with which Google crawls your site is largely dependent on PageRank. So keep working on getting more links from other well-ranked sites whose main topic is related to yours, and do your best to set up your internal links in a hierarchical structure to help Google crawl your site more thoroughly and efficiently.
If you make seo friendly urls, unique meta info and what Thanpa said every single one of your pages will be indexed on Google, MSN and Yahoo
Have quality content and unique meta tags for your new pages, focus more on your website inner linking structure and build an updated XML sitemap.. submit it and for sure you still need quality backlinks and then.. WAIT
