How AB tests work<\/h2>\n

AB tests on Facebook allow you to create multiple ad sets<\/strong> and make comparisons based on different variables<\/strong>.<\/p>\n

However, when designing a new test you can only define one variable to track since it is necessary to actually know what was changed and what results this change generated for your campaign.<\/p>\n

During the broadcast the audience is distributed into random groups<\/strong> which helps ensure balance when displaying ads and acquiring more legitimate comparison data.<\/p>\n

Thus, when a campaign ends, the cost per result of each ad set is calculated<\/strong> and the one that performs best wins the test.<\/p>\n

The advertiser then receives all the information via email and can use it to plan more strategic and effective campaigns based on these analyses.<\/p>\n

    • creative<\/strong> you can create between two and five versions of the ad to test images, texts, videos, titles, and\/or Call-to-Actions (CTAs). To clearly see which change achieved the best results, it is ideal to change only one creative element per campaign<\/li>\n
