OpenAI has informed ChatGPT Ads advertisers that automatic advanced matching will become the default on existing web pixels from August 17, 2026, according to a product update email distributed during the week beginning August 3, 2026. The feature, which uses hashed customer information from website forms to attribute more conversions to ads, is already switched on by default for newly created web pixels. Advertisers who do not want it on existing pixels have until that Monday to disable it via the Tools menu, then Conversions, then Data Source, then Edit pixel. No action is required to accept the change. Barry Schwartz published the email’s contents on X on August 5, 2026, and Search Engine Roundtable carried a consolidated account. The email also detailed nine changes to the advertising stack, including conversion-optimised cost-per-click (oCPC) campaigns, now available in beta for product feed campaigns. This initial release supports click-billed campaigns using fixed or manual bidding with a positive conversion bid cap. Existing CPC campaigns can be cloned into new oCPC campaigns, and oCPC campaigns can be created in bulk. During cloning, Ads Manager prefills the conversion event when a single eligible event is available, otherwise prompting for a selection. Conversion-optimised campaigns began rolling out on June 5, 2026, gated on advertisers having at least one conversion event flowing through the Pixel or Conversions API.
