Nawala yung Page Rank Ko

I don't really understand how google mind is. I didn't expect for what happen to my blog after a weeks done. I notice that my toolbar has no green small bar and only shows no rank on this page. As I observed for this google page rank updates many of sites have got a PR1 and some are penalized that would got a PR0, some good and some bad.

In the busby seo test blog I only got a PR1 and i'm hoping it will continuing on getting a high rank. So I keep in always maintaining. Hindi ko nga maintindihan kung bakit bigka nalng nawawala ang page rank ng isang site. E wala nmn akong ginawa dati may PR1 nung isang linggo but ngayon wala.
