Hi saurik, that's one of the earliest videos I ever taped, back in 2006: http://www.mattcutts.com/blog/more-seo-answers-on-video/ http://www.mattcutts.com/blog/more-seo-answers-on-video/ I had to move that video over from video.google.com, which is why the YouTube date appears more recent. I should probably make a new video or blog post about A/B testing, but I can try to summarize here. In the original video, I said: - it's nice if you can A/B test on a part of your site that Google doesn't see. Then it's a moot point for us. - failing that, it's helpful to do something server-side. - don't do anything special for Googlebot. The state of A/B testing has evolved quite a bit in the last six years though. If I were making a fresh video, I'd say: A/B testing is a perfectly fine thing to do. You can do A/B testing via either server-side or client-side technology. In both cases, don't do anything special or different for Googlebot. Treat Googlebot just like any other user and don't hard-code our user-agent or IP address.
