Ad serving is only the beginning.

Most ad servers were built to deliver ads. Modern commerce media needs to decide which ads deserve high-intent moments, how budgets should pace, how relevance and quality affect ranking, and how to optimize for both retailer revenue and advertiser outcomes.

That is the job of an intelligent ad engine. T-Engine turns ad serving into commerce-aware decisioning.

What makes T-Engine intelligent.

Every decision balances bid, relevance, budget and outcomes, in milliseconds.

01Real-time auctions

Commerce-native auctions that balance bid, relevance, placement, budget and business logic in milliseconds.

02Budget pacing

Control how advertiser budgets are spent over time so campaigns do not burn too fast or under-deliver.

03Quality score

Quality and relevance signals protect customer experience and improve long-term advertiser performance.

04Attribution-aware optimization

Connect ad decisions to clicks, conversions, attributed purchases and revenue.

05Relevance controls

Rank ads using query, category, product, seller, placement, availability and shopper intent.

06Yield optimization

Improve revenue without reducing marketplace quality or advertiser trust.

07Full-funnel decisioning

Optimize across impression, click, conversion, purchase and revenue, not a one-step delivery event.
