What happened?
TikTok Shop US launched the Product Diagnostics feature on November 12, 2026. Integrated into sellers’ Product Analytics, the feature adds a list of products that need attention, explanations for changes in product GMV, benchmarks from top-performing sellers in the category, and related action entry points alongside existing GMV, traffic, and conversion data. The system also breaks down product performance by affiliate livestreams, affiliate videos, seller livestreams, seller-created videos, and Shop Tab & Search. This helps sellers further assess whether declining product sales are related to traffic, price, inventory, ratings, affiliate promotion, product opportunities, or account health. The feature is currently available to sellers in the US market. It is an operational analytics feature, not a mandatory policy. Its analysis can support sellers’ product selection, inventory, and advertising decisions, especially for stores with many SKUs that operate both short-video and livestream channels. Sellers can also assess future product performance by comparing their own period-over-period results with gaps relative to strong sellers in the same category.
What does this mean for cross-border sellers?
US sellers can view products that need attention, reasons for GMV changes, top-seller category benchmarks, and performance across different traffic scenarios in Product Analytics. Use the diagnostic results to distinguish traffic, price, inventory, rating, affiliate-promotion, and account-health issues before deciding on restocking, product selection, or advertising changes, rather than relying only on total GMV.
What should sellers do now?
- 1Log in to US Product Analytics this week, review each priority SKU marked as needing attention and its GMV-change reasons, and organize an issue list by affiliate livestreams, affiliate videos, seller livestreams, seller-created videos, and Shop Tab & Search.My AI Agents
- 2For US SKUs that require restocking, compare your period-over-period performance with the top-seller category benchmark, distinguish inventory, traffic, and product-opportunity issues, and prepare a replenishment-procurement list covering products to continue stocking, defer, and monitor.Procurement List
- 3Check performance differences for priority US products across affiliate livestreams, affiliate videos, seller livestreams, and seller-created videos. Add the corresponding content or creator promotion for scenarios with insufficient traffic, and retain a scenario diagnosis record for each SKU.Creator Outreach
- 4For US products whose advertising performance is covered by the diagnostics, review campaign effectiveness together with traffic, conversion, and GMV changes. Create an advertising adjustment record for each product and specify whether each SKU will be retained, optimized, or paused.ACoS / ROAS calculator
