ChatGPT Ads adds oCPC bidding and a product carousel

OpenAI updated ChatGPT Ads Manager on August 7, 2026, and every change lands 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 at the bottom of a conversation. For retailers already treating ChatGPT as a shopping surface, this is the update that makes the feed itself the thing worth optimizing.

What changed in the August 7 update#

Search Engine Roundtable’s report on the OpenAI advertiser email lists four changes, all scoped to product feed campaigns rather than the platform generally.

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: the advertiser still pays per click, but delivery shifts toward the clicks OpenAI predicts are likeliest to convert. 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 side by side in a single unit at the bottom of a ChatGPT conversation, letting a user compare items without leaving the exchange they are already having.

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 but related change to the same measurement stack the oCPC beta depends on for conversion signal.

Why this matters for feed visibility, not just bidding#

Every part of this update assumes the advertiser already has a working product feed connected to ChatGPT Ads Manager, because oCPC needs conversion data tied to individual feed items and the carousel needs multiple eligible products to place side by side. 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 will not get a meaningful lift from oCPC, because the model has weaker conversion signal to optimize against in the first place.

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 no efficient 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, will be the ones oCPC’s conversion signal actually favors once it leaves beta.
