How often google re-index a site

It depends on adding contents frequency at your blog.

DON.

After Google finishes all the crawlings they have made, then they'll index it. Google made some minor crawling almost everyday and major crawling once a month.

It depends on the site page rank I think...The higher the page ranked, the deeper the site is indexed.

That depends on the Page Ranking. The higher the ranking, the more is the possibility of being indexed.

Usually it depends on site rank. when you are not having any PR the only 1st two paragraphs and the last paragraph is indexed, not the complete post. And as time passes and you get some higher page rank, then it indexes the complete post, but not every post. And when the PR goes more better, it indexes all the posts which helps in having a good traffic from search engines.

I don't think so

My page ranking seems to only ever get better when my 'adwords' campaign is running. Although it does generate clicks for me, it seems an expensive way of working my way up the rankings.

If you update your website very frequently then Google tries to keep up with it and will update it every day. Pagerank is something I would not worry about. A lot of mis leading information out there.

Ahhhh...so that's why my site get's new pages indexed super fast by google when my adwords campaign is switched on.

I beleived quality of links and frequent updates of site can make a difference in terms of page indexing.
