Avail eMarketing Suite contains an automatic A/B testing functionality, which means it will randomly assign every nth (usually every 1000th) visitor into a control group (group B) and all others into the Avail eMarketing Suite group 
(group A).

All visitors in group A (Avail group) will be subject to features from Avail software, while all visitors in group B (control group) will be subject to randomly selected product recommendations from your site’s top-list.

By comparing the Conversion Rate and Avarage Order Value of visitors in the A group vs visitors in the B group, Avail software calculates the actual contribution to Sales that it has generated for our customers in real time.

The results are available to our customers in real-time in an easy-to-use web-interface.
