We converted our vB4+vBSEO board on (update) December 01 and I've been noticing a decline in the Google organic traffic. I'm keeping a check on how many pages are indexed by Google and surprisingly Google's got larger number of URLs listed. My best guess is that it's because of the new URLs Google's discovered because of Xenforo. The old links are being removed from Google's index at the rate of about 3k URLs/day and new URLs are being added at the rate of about 2k/day. We do not have a sitemap because I'm not satisfied with the current addons. Can someone suggest steps to recover the traffic?
