The pagerank of one of our established website was dropped from PR4 to PR0 recently. It happens to the home page only, the pagerank for internal links seem to be fine. We still get same amount of traffic from google.
The site has been up over 6 years and have a stable PR4 in the past. Any other sites experience the same issue in the past couple weeks? would this be another glitch in google's recent update? or it could be a penalty to the site?
