I wanted to know how long does it take for Page Rank to change. I have been doing a few link exchanges with pr2 and pr3 sites. Thanks
Google will usually take 3 months for PR updation initially. But try to get links from high PR sites so that it will boost your ranking quickly. Getting links from high PR sites increases the PR of a site. You will see the result definitely.
keep building backlinks and PR will come. depends on how many backlinks you have and what is the quality of those backlinks
Google takes at least 3 to 6 months to recognize and give value for inbound, to avoid paid links. About Google Page Rank, its up to Google, but dont worry about PR but concentrate your affords to build a solid and good SERP. Cheers Lucio
