ChatGPT Ads adds oCPC bidding and a product carousel

OpenAI updated ChatGPT Ads Manager, Search Engine Roundtable reported on August 7, 2026, and most of the changes land on the product feed side of the platform: conversion-optimized cost-per-click bidding moved into beta, landing page links gained macros for attribution, and a multi-product carousel format started testing. For retailers already treating ChatGPT as a shopping surface, this is the update that makes the feed itself the thing worth optimizing.

What changed on August 7?#

Search Engine Roundtable’s report on the OpenAI advertiser email lists four changes that matter here. It also lists other updates, among them Triple Whale and Hightouch integrations, pixel diagnostics and a Brazil and Mexico launch.

oCPC bidding entered beta. Conversion-optimized cost-per-click campaigns are now available for product feed campaigns. The initial release supports click-billed campaigns using fixed or manual bidding with a positive conversion bid cap. Advertisers can clone an existing CPC campaign into a new oCPC campaign, or create oCPC campaigns in bulk, with conversion events prefilled where they already exist.

Dynamic URL parameters went live. Landing page query parameters now support the macros campaign_id, ad_group_id, ad_id and ad_account_id, populated automatically at delivery time. That closes a basic attribution gap: a retailer can now tell which product feed campaign and ad drove a given session without hand-building URL variants for every SKU.

A multi-product carousel format entered testing. OpenAI is testing a carousel that places several products from one advertiser’s feed in a single unit. Brodie Clark said on X that it was already live on August 7.

Automatic advanced matching gets a deadline. Advanced matching is already the default on new web pixels. OpenAI will turn it on for existing web pixels on August 17, 2026 unless the advertiser opts out before then, a separate change to conversion measurement.

Why feeds matter, not just bids#

Every part of this update assumes the advertiser already has a working product feed connected to ChatGPT Ads Manager, because the carousel shows several products from the advertiser’s feed in one unit and oCPC is offered only on product feed campaigns. That puts ChatGPT Ads in the same position Google Merchant Center has occupied for years: the feed is the asset, and bidding or ad format changes only compound on top of feed quality that is already correct. A retailer whose feed has thin titles, missing images or unclear availability is unlikely to get much from these changes.

The dynamic URL macros matter for the same reason technical SEO people already care about clean attribution: without campaign_id and ad_id resolving automatically, a retailer running product feed campaigns at scale has a harder way to tell which SKUs and creative combinations are actually converting inside ChatGPT, as opposed to which ones simply got the most impressions.

Why we care#

This is a bidding and measurement update dressed as a shopping feature, and that is the useful reading of it. OpenAI is not yet describing feed submission mechanics the way Google documents Merchant Center’s spec, but the direction is the same: retailers who treat their ChatGPT product feed with the same rigor as a Merchant Center feed, accurate titles, current pricing, working images, are the ones best placed to benefit once oCPC leaves beta.
