What is creative testing?
Creative testing is the practice of running different versions of an ad's images, video, copy, or format against each other to see which performs best. The results show which ideas to scale and which to retire.

What you can test
Almost any part of an ad can be tested. Common choices include the opening hook of a video, the image, the headline, the offer, and the call to action.
Testing a big idea, such as a different message or format, usually teaches you more than changing a single word.
How to run a clean test
To isolate a creative effect, use a platform experiment that randomly assigns eligible people or traffic to mutually exclusive versions. Change one element, keep other settings constant, and plan the sample size and stopping rule before launch. Similar audiences and budgets alone do not guarantee a fair causal comparison.
Decide in advance which metric will pick the winner. Matching it to your goal, such as cost per acquisition, keeps you from chasing clicks that don't convert.
Why creative testing matters
Creative often has a large effect on results, because it decides whether anyone stops and responds. Regular testing also gives you a steady supply of fresh ads, which helps with ad fatigue.
Common questions
What is the difference between creative testing and A/B testing?
A/B testing is a method that compares two versions. Creative testing applies that idea, and others like it, to ad assets such as images, videos, and copy.
How long should you run a creative test?
Run it until each version has enough results to compare fairly. The time needed depends on your budget and conversion volume, so avoid calling a winner after a day or two of thin data.
How many ads should you test at once?
Fewer is usually easier to read. Each added version splits your budget, so it takes longer for each one to reach a useful amount of data.
What should you do with a winning creative?
Scale it carefully while watching for fatigue, and use what you learned to brief the next round. A winning angle can often be reused in new formats.
