For a while now webmasters have fretted over why all of the pages of their website are not indexed. As usual there doesnt seem to be any definite answer. But some things are definite, if not automatic, and some things seem like pretty darn good guesses.
So, we scoured the forums, blogs, and Google’s own guidelines for increasing the number of pages Google indexes, and came up with our (and the community’s) best guesses. The running consensus is that a webmaster shouldnt expect to get all of their pages crawled and indexed, but there are ways to increase the number.
