TikTok has updated GMV Max to include affiliate commissions, discount coupons, and platform fees in its campaign ROI calculation, changing how the metric reads for TikTok Shop advertisers.
What changed in GMV Max
The prior version of GMV Max measured returns against gross transaction value without deducting seller-side costs. For TikTok Shop campaigns that generate purchases through creator affiliates or coupon-based promotions, this meant the metric could overstate campaign profitability on a net basis. The updated calculation subtracts commissions, discounts, and fees before reporting ROI.
For campaigns using TikTok Shop's affiliate model, where creator commissions can range from five to thirty percent of the sale price depending on product category and creator tier, the difference between gross and net returns can be material. A campaign that appeared profitable under the prior metric may read differently when seller-side costs are applied. TikTok says the update is intended to give sellers a more accurate measure of campaign performance. The company has not disclosed data on how many TikTok Shop advertisers are currently running GMV Max campaigns.
Auto Selection
Auto Selection draws from three creative sources: creator-submitted content, product catalog assets, and Symphony AI-generated content. The tool allocates each asset algorithmically to the placement where it is predicted to perform best, removing the need for advertisers to manually assign creatives to specific ad slots. Advertisers define the available pool of assets; Auto Selection handles deployment and continues to optimize allocation as the campaign runs. TikTok says the tool is designed to remove the manual creative-testing phase of campaign setup.
Asset Manager
Asset Manager consolidates a brand's product catalog, data connections, and creative assets into a single interface for campaign launch. Previously, these inputs required navigation across separate sections of TikTok Ads Manager. The centralized view reduces the number of steps needed to move from asset preparation to campaign activation.
AI-powered Summary
AI-powered Summary analyzes performance data from active campaigns and surfaces optimization recommendations in real time. The feature is positioned as a replacement for mid-flight manual reporting, generating actionable signals during the campaign's active period rather than requiring advertisers to pull and interpret custom reports separately.
Competitive context
Auto Selection operates in the same category as Meta's Advantage+ Creative and Google's Performance Max, both of which automate creative selection and placement allocation across their respective inventories using machine learning. Asset Manager follows a consolidation approach comparable to Meta's Business Suite and Google's Asset Library, which centralize campaign inputs within their platforms.
All four tools were presented at TikTok World, the company's sixth annual advertising product summit. Full details are on the TikTok Newsroom.
Recap

GMV Max now factors in affiliate commissions, discount coupons, and platform fees when calculating campaign ROI for TikTok Shop advertisers. The prior version measured returns against gross transaction value without deducting these seller-side costs, meaning campaigns that relied on affiliate creators or coupon-based promotions could appear more profitable than they were on a net basis.
