Adobe’s entry into the world of AB testing comes in the shape of Adobe Target, part of Adobe’s wider Marketing Cloud. Packed with advanced testing and targeting functionality out of the box, there’s also the option to add your own JavaScript where required, so you can strive for total customisation of your testing. The WYSIWYG version of Test & Target has been known to be buggy, but it’s worth persevering given the powerful testing options available at the other side. With Test & Target, you can create numerous different tests across a series of different bases, before hooking up with Sitecatalyst so you can take advantage of all that juicy data.
