One of our partners news forum site has its traffic dropped after changing its url from dynamic one to a readable one. Indexed pages in Google have also dropped. How long will this go? Because of the change, my friend's site lost traffic and perhaps some adcents revenue, which is very, very little and can barely pay server cost. One suspicion why there was a dramatic drop of forum site was Google's newly introduced seo algorithm, which is site speed (one of the 200 algorithms in determining search ranking). Please check this news forum site whether it loads fast from your end. thank you.
