I'm thinking of moving to Xenforo. Currently i'm using vBulletin 4.2.0 and I have a really bad pagerank in Google of zero. In the past when I was running vBulletin 3.6.x with vBSEO it was like 3 or 4, and the traffic from search engines was great. Now it's horrible, and I'm looking for a way to improve it.
vBSEO is no option due to the troubles and security issues the have.
Will Xenforo make the difference? Will it improve my pagerank and search engine traffic? I have more than 3 million posts, is that a problem? My forums are at http://forum.scooterforum.net
