It's not about the ranking really but about the PR although PR is one of the 200+ factors use by google to rank sites. PR is all about links determined by quality and quantity. So if you have a high PR, it means your site is listed on a lot of places and as google crawls the other places, it will find the link to your site and crawl you as well. Do you get the picture?
The answer to the 1st question is No and the 2nd question is Yes. High PR means you get crawled more often but to get indexed faster you need original content and not too many dofollow links as Google stays on your page rather than following your links
PageRank is the primary factor in determining the depth and frequency with which Google crawls a site. Crawl frequency is also affected by how often you update your site. And in some circumstances, the speed with which your site responds can also be a factor. If your server is unusually slow, which can easily happen with dynamic pages on shared servers, they will slow down your crawl rate to avoid problems.
From my experience yes! I own a site which is a PR6 and this gets crawled/cached every 2 - 3 days, saying this tho i do upload fresh new content everyday which in turn gets ranked normally within 4 hours.
My site gets crawled daily or so. I also add new content all the time and have a blog and forum as part of the site. Cheers APHP
PR has nothing to do with indexing. The site regularly updated with unique content tends to get indexed faster.
Exactly, its pretty simple and straight, all those big sites which updates their content every 2-3 days or in a week or so, They tends to get indexed quickly, as google bots visit those sites almost everyday.
what I know is forums.digitalpoint.com has high + natural PR and dp's threads and posts are indexed very very very fast fast fast nothing bad to have high PR isn't it
