About solutions for scaling Auction Ad spend

Last updated: April 2025

Scaling auction ad spend is a strategy in TikTok Ads Manager that helps you increase your ad budget and reach a wider audience while maintaining or improving performance metrics. Once your campaigns and ad groups pass the learning phase and generate consistent conversions, you can begin to scale your auction ad spend at a rate that is in line with your risk tolerance.


Key concepts for scaling auction ad spend

TikTok Ads Manager uses a learning phase to find the right audience for your ads. Your cost per action will vary until the system is able to identify the people most likely to convert. This is important because if you attempt to calculate your return on ad spend (ROAS) before passing the learning phase, you won't have accurate data about your true advertising costs and cost per action.You'll start with a relatively low budget to test a variety of campaign settings and creatives. As you find winning combinations, you can start to increase your budget. The types of campaigns will generally determine how you can measure success:

  • For conversion campaigns, you can start to scale when an ad group generates at least 50 conversions within a week and when the campaign meets or exceeds your performance metrics.

  • For non-conversion campaigns, you need to analyze your targeted cost per action. Your campaigns and ad groups should be spending 90-100% of their budget with the cost per action at or below your target. This indicates that the system will be able to sustain the results while reaching a wider audience.


Optimization tips for scaling auction ad spend
