What could be the reason. My blog was doing fine till that. I am doing paid posting could it be this resulting having my blog banned?
Blog banned from where? Try searching by site:url If you see results, no need to be worried that your sites is excluded from Google's search engine. Seems you are talking about PR. Paid posting = should be reason. Did you also sell links?
Exactly about PR. There many paid oppurtinities that requir to include link in the post. I am fearing that might be the reason for the PR drop.
well my blog came from pr2 to pr0. I dont sell links nor anyone besides me have posted in the blog? Any idea?
Forget PR and google's hypocrisy...we are webmasters of our blogs...not google. Yes, we have full right to attract sponsors and advertisers. What matters is traffic and revenue.
Why Google will give you PR since you will be using it to distribute false votes to other sites? Google Page Rank or paid posts? Choose one. You won't be able to have two under this new Google Internet. I would say that just ignore PR and work the best contents out of you. Advertisers don't buy PR any more because whether you like it or not, you might get banned tomorrow.
One of my sites dropped seriously (but not to zero thankfully) after the update - I've sold some links too. It looks like they might be tightening up a bit.
