About Auction Ads

Last updated: April 2025

Auction ads on TikTok are a way to bid on how much you're willing to pay to have your ads shown to people. Unlike Reach & Frequency campaigns, which allow for pre-booking and fixed CPMs, auction ads are delivered through a real-time bidding process.

Benefits

  • Dynamic optimization: The auction system continuously optimizes your ad delivery to maximize performance.

  • Flexibility: You can adjust your campaigns in real-time based on performance data.

  • Cost efficiency: By setting the right bidding strategy, you can achieve cost-effective results.

  • Scalability: Auction ads can scale based on your budget and performance goals.


How Auction Ads work

When you create an auction ad campaign on TikTok, the auction considers several key components:

  • Bidding strategy: Determines how much you are willing to pay for specific actions, such as clicks or conversions.

  • Ad creative: The quality and relevance of your ad content, including videos and images.

  • Audience settings: Defines the demographic and interest-based targeting for your ads.

  • Ad account structure: Organizes your campaigns, ad groups, and ad versions for better management and performance.

Your choices in these areas will influence the performance of your ads and the cost per action (CPA) or return on ad spend (ROAS) you achieve.

When to use Auction Ads

Auction ads are ideal for campaigns that aim to drive specific actions and conversions. Consider using them when:

  • You need to drive conversions or purchases.

  • You want to test different ad creatives and audiences.

  • You have a dynamic budget.

  • You are running short-term or highly targeted campaigns.
