Finally, the mystery about why pagerank suddenly goes up from 4 rank to 5 rank is solved :)) While trying this excelent SEO tool, named PageRank Prediction, I found out that the 4 rank on Google is for http://blog.funponsel.com/ and the 5 rank is for http://www.funponsel.com/blog :p

I started using subdomain name for my blog about 2 month ago, so that’s why the pagerank is differ than my original blog address. My other URL address, the free .TK domain, got lower rank on Google. Simply because I use it for only 1-2 weeks, on my first blogging experience

Case closed! :p
