Almost everybody knows PageRank plays a great role in determining your site’s position in google’s large webpage database, but less people have noticed that PageRank also determine how many pages or how fast the crawlers from google will index your pages.

Here is my own experience from MapList.Org. About a month ago, when maplist has a PageRank of 3 and some of the local sites, for example http://toronto.maplist.org, have 3 too, Google indexed about 400,000 pages.

Then, due to some reason, the PageRank dropped to 2 and now the pages for MapList in Google’s database has dropped to 40,000 and the number is still decreasing.

As for how to increase your PageRank, everybody has his own answer, but one of the most important one is to improve your site quality and so that more natural links will appear for your site.
