Split-testing, also know as A/B testing, is the best-known type of optimization experiment, pairing different versions of your website against one another to see which performs better according to specific metrics.

And in version B, you might create a new version that places your call-to-action below the fold instead. Then, after conducting your split-test, you can compare to see which placement got more visitors to take action.(more…)
