How to Test Your SEO With Rigor

Unlike multivariate testing for optimizing conversion rates, where many experiments can be run parallel, SEO testing requires a serial approach. Everything must filter through Google before the impact can be gauged. This is made more difficult by the fact that there’s a lag between making changes and having the revised pages get spidered, as well as another lag while the spidered content makes it into the index and onto the search engine results pages (SERPs). On top of that, the results delivered depend on the search history of the user and the Google data center accessed.
