This method is still under testing for last 2 months, but I’m very sure it will increase your pagerank in next update. I’m expecting at least PR3 from PR1 in next update. You need to get a lot of dofollow backlinks from higher PR sites. You cannot buy links with dofollow as they might penalty your existing PR to zero. The only legal way to get dofollow link with PR juice is by our hard work.
I have a collection of more than 100 blogs that have “Top Droppers” widget on their blog. Some blogs gives credit to their top droppers early of the month by writing a post about top droppers of the month. I bookmark them and committed to drop on all of them everyday. This gives me a lot of dofollow backlinks at the end of the month.
One of my blog has been penalized for giving dofollow paid posts. I have removed all dofollow links from paid posts and get a number of backlinks this time. I’m hoping to get some pagerank juice in next update for this penalized blog as well. Nothing is for sure now. If I can regain my lost PR, I will definitely share my entire experience on how to regain lost page rank here.
I’m going to try another way which is easier and more effective than the above method. Will apply this after next google pagerank update and share the details here soon. If you have any good and easy idea on technique to increase pagerank, please share.
