Welcome to the Q&A Forum

I have used vBulletin with vBSEO for a number of years and have been happy with the SEO results that I have achieved. However, vBulletin's recent releases have become unstable, full of bugs and are not secure. I am intending on starting some new forums in the near future and would like to move away from vBulletin. I have heard good things about Xenforo and IP Boards. Does anybody have any experience with either platforms built in SEO functionality?

Google Authorship seems to be the current buzz topic in SEO. It seems perfect for people who write lots of articles of blog posts, but what about sites where the main focus isn't articles e.g. e-commerce sites? Can the website as a whole get verified?
