Just went live on a vb to Xenforo conversion. Have rebuilt everything, have redirects in place that seem to work and pointed Google webmaster tools at the Xenforo sitemap. Google now says there are 33,432 pages submitted versus the previous total indexed according to Google that used to be in the range of 400,000. Any idea why such the hit in the new sitemap?
Looking at your forum, 33,000 seems about right -- you have around 31,000 threads and that will be the bulk of it. I don't have a clue how you could have 400,000 entries before unless there was an entry for every post, which doesn't really make sense IMO.
