On Facebook, an advertiser needs to keep the creatives fresh in order to engage the audience. It’s a god idea to test different elements that make up an ad (like the image, body etc) to check which one is performing well. And at the most basic level, that is what the multivariate tool allows you to do – to test different elements of a creative so we know which ones are working well (based on target).
This tool gives you a few additional benefits (like allowing you to conserve your budget). Please contact our Sales team in order to get more information.
