Key Features & Benefits: AB Tasty offers several capabilities that digital marketers will find useful. There are five different types of content experiments supported:
- A/B testing – Create different versions of the same page by modifying individual page elements, then measure performance.
- Predictive testing – Predictive tests allocate traffic dynamically between several variations of a page. Users will be preferentially directed towards the page that performs best with respect to stated experimental objectives.
- Multivariate testing – Create multiple variations of several different page elements, then mix and match them to find out which combination performs the best.
- Multi-page testing – Test multi-page experiences (like sales funnels) against each other to see which one converts the best
- Server-side testing – Implement server-side testing to measure the performance of factors that are invisible to users, but may still impact conversion rates. Server-side tests are coded directly onto your website instead of being applied via the client browser.
How to Get Started: With no free trial available, you’ll have to contact AB Tasty to set up a product demo before you can get started.
