At June of last year, many of blogs pagerank change. Most of them get decreasing pagerank significantly. My blog drop from PR4 to PR2, this condition directly affected to my earning. This is not happened to me only, many blogger also affected.
And since I believe there’s impossible to change it, or asking for change to Google, I just keep silent, mad inside but keep trying to increase the page rank. Pagerank is backlinks, you want good pagerank, and you should increase your backlinks.
Actually, most important is not pagerank but traffic. Good traffic tells people your blog quality. Many traffic will shows that your visitor happy with your blog and returned. Good backlinks will increase your traffic automatically. So, it’s worth to make link exchange or buy backlinks to high traffic website.
At this year, Google makes changes to its algorithms. And again many of blog suddenly disappear from Google search engine. Some rumors telling about Google Dance, Google Sandbox and Banned. And again, there’s no documentation about this. What we can do is just trial and error, thing about some possibilities, make changes and test the result.
I really hope Google will not change my blog page rank this midyear. It’s really sucks to put backlinks everywhere. Anyway, keep working and keep earning.
