I want to increase my sites pagerank and i have been getting backlinks, but how will i know/when does google update pagerank rating?
Google updates PR internally every day and factors that into the rankings every day, so you would have got the benefit from the backlinks. They export a historical snapshot of that internal PR to the toolbar every 3-4 months - your rankings do not change then as the PR is already factored into the rankings.
Hi, Last PR was updated on October, It updates every 3 months but now a days people are not concerning much about PR because it's not a main parameter for SEO any more.
A minor PR update happened during November second week, and we cant say for sure when will the next PR update will be, as Google takes its time. You continue to build backlinks and practice other seo techniques and time will tell when the next Pagerank update hits it.
It happens once in 2-3 months. But, I never care for it. It does not seem to be important for my website.
Why bother with your page rank? Just focus on delivering traffic to your site. It would be better if you will target more keywords and rank them in high positions.
No need to worry about page rank. you can see the number of backlinks from Google webmaster. It does not show you all the backlinks, just some of the most recent ones.
