Aaron Wall over at SEOBook.com has an excellent write up on the recent indexing phenomenon at Google. The search engine major has supposedly been indexing ever lesser pages lately. Webmasters yearning to get more of their pages indexed and found by searchers. Aaron posted a blog entry he named The Google Crawling Sandbox. He has taken the title of the post comes from the concept that Google slowing down its crawl process. The solution that Aaron suggests is unique content. The reason being if it's "legitimate useful content" then more people will want to read it. Consequently, Google will crawl it better. So the call is not to focus on search engines only.
