I think its rather hard to tell what results vBSEO has done for vBulletin installs. Some people report a dramtic increase in revenue from CPC programs such as adsense, some report a jump in the SERPs and Page Rankings. Then you have some who report nothing, or have results that arent desirable or worth typing out. One thing is certain that it takes a period of time to start seeing the results.

Since its almost impossible to have a perfectly controlled experiement of two identical boards, one with vBseo and one without to see which does better its near impossible to tell where any one would be without it, as compared to where they are with it.
