How long will my Site Increase it's PR? after link building..

It depends on how often you do link building activities..and if the contents of your sites are good..i can suggest that do link building often and make the contents of you're site interesting...

You should keep on doing link building until the google crawler crawl your website and google crawler comes after each three months.

any buddy dont know when google crawl your website for pr ma be every 3 months pr crawler crawl your website

thanks for the info guys.. now I have to do link building more often .. I have done some link building activities for a month.. hope that my site could get a PR.. thanks

i have heard google reviews pr after every 3 months.

And after the three months is up, it's a good idea to do some maintenance linking so you don't drop after the next crawl.

Dont wait for anything. Link building is a daily work. Do it regularly soon your site get good pr. Google will announce their pr update in every three months. Before the announcement, try to have a many backlinks.

It depends your link building well or not, content richness.And you should keep on doing link building,do well Web Engine Optimization.

focus on getting good number of quality back links instead of worrying your PR.
