Resources include a wordpress plugin, a webinar and an interview with Google’s Tom Leung.

  2. Multivariate testing on this scale used to cost thousands a month. Now small businesses can optimize their landing pages at a level previously available only to those with deep marketing pockets. GrokDotCom has some incredible resources for those getting started.
