A campaign experiment lets you test your draft’s performance against the original campaign's performance. Experiments use a portion of the original campaign’s traffic and budget and run alongside the original campaign for a specified length of time.
- After you’ve created a draft, you can convert your draft to an experiment.
- As your experiment runs, you can monitor and compare its performance against your original campaign and choose to end the experiment. Once you end your experiment, it will stop running by the end of the day.
- For any given campaign, you can only have one experiment running at a time.
- Experiments are only available for Search and Display Network campaigns.
