My site www.top10imagehosts.com went from a PR0 to a PR4 once the update occured. Does anyone have a clue why this is?
same happened to me about 2 mos ago. It still hasnt gone down. im not complaining either. I only have 1-2 strong backlinks to it also.
It might be because you have strong backlinks...get quality, trusted and related site with good PR and it'll increase...
