Ezoic Ad Tester is a great way to get your feet wet in the world of A/B testing on your own version of your website. You can create up to 100 different ad units, place them on your site, and Ezoic Ad Tester will automatically test the different combinations of those locations including colors and sizes - to find what works best for each page of your site on each device. Ezoic Ad Tester will only display the correct number of ads on each page - so, for example, you can place 20 ad units on a page and it will display the best 3.
In the Ezoic Publisher area, you can quickly create many ad units. You then place these units on your site. Ezoic will start testing different combinations of those units and will soon start showing the best performing combinations more often. Your revenue will increase.
Testing more things is almost always a good idea, however it's highly unlikely that manually selected ad locations will out perform an automated system - especially one that tests for user experience as well. That said, the full Ezoic system will also test the locations you chose in addition to the ones it automatically tests so it is helpful to create some Ezoic Ad Tester ad units even if you don't enable the Ezoic Ad Tester feature.
Up to 100
You can set the maximum number of ads to show in the Ezoic publisher area - up to 5 per page.
