It’s simple: Rekko portions out a percentage of visitors on your site as the test subjects. These test subjects will randomly receive one of the creatives in your campaign. The creative that performs best according to the goal you’ve set will be declared the current “winner” and will be delivered to the rest of the visitors that come to your site.
This test is ongoing, though! That means Rekko can account for trends among your visitors. If one creative starts doing better than another within the test group, the better performing creative will be delivered more often.
This means you can create “set-it and forget-it” campaigns in Rekko. Let us do the math for you.
