Can anybody please explain why my site suddenly dropped from a PR2 to a PR0. This was only about a week ago. I didn't do anything different to cause it. Checked my rankings in the search engines and there the in the same positions as before. Have around 1040 indexed pages in Google. Site is about 7 months old and is a forum. Thanks for your help.
I think No one can be explain about pagerank..As you can see that there are many sites who has pagerank with low backlink but in other hand many site with huge and quality backlink but has low pagerank..To make it simple you have check your backlinks? increase or decrease?
Your website may have violated Google's webmaster guidelines. Or it may have links from spammy websites or something else. It's not easy to find out the exact reason. All you can do is to make sure that your website complies with google's guidelines and is free of spam.
Sometimes sites just jump around a little. If it is permanent though, it may because your site was seen as doing something "black hat"?
Checked my PR yesterday and it's back up to a PR2. Don't know why it went to zero for about a month, but good to have it back.
This was happend to me, I got PR3 and then going to PR0 for three months, I'm then recheck the back links and start concentrating on OFF page more on quality links, Right Now become PR4
I agree with lightless's advice of following Google Webmaster guidelines: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=35769
Usually, if your site is really PR2 in value, PR will show as 0 if data center is down, but it won't take long to show the original PR back again.
One of the frustrating things about forums is that if you don't keep a very close eye on the links that are coming in, your PR can suffer. One of your posters links to a "bad neighborhood" site, for example (such as a spam or MFA site), and you're toast. The easy way to avoid this is to modify your forum to make all user-submitted links "no follow", but this can reduce the popularity of your site. Another big problem is paid links. If Google picks up on paid links within a site, PR can drop through the floor. It takes a little creativity to keep paid links from looking like...well, paid links, but this can seriously save your site's PR.
