Use the split test toggle in the TikTok Ads Manager when creating a campaign to test two different versions of your ads to determine which one performs best and to improve future campaigns.
To create a split test:
Go to TikTok Ads Manager.
Click the Campaign tab.
Click Create.
Choose an advertising objective.
Click the Create a split test toggle.
Click Continue.
Complete the settings in the Ad group tab and continue. Note: Set the test schedule dates to at least 7 days so that the system has enough time to collect a useful sample.
Complete settings under the Ad tab and continue.
Select a Split test variable in the Split test tab.
Select a Key metric. The system uses the Key Metric to compare the two ad groups and determine the highest performing ad.
Set up your Test ad group.
Click Complete.
