The Maze: Meta will start rolling out a new default for counting website purchases on November 12, 2026. Eligible advertisers may see more sales credited to their ads without receiving more orders. The feature excludes shoppers in the European Union and UK and requires a qualifying website setup.
Source: Meta. Meta explains on-device purchase matching and the EU/UK exclusion in its public help documentation.
The Details:
The purchase already happened. Meta Pixel is website tracking code that tells the owner of Facebook and Instagram about actions such as purchases. Normally, Meta connects those actions with earlier ad interactions. It cannot always make that connection. The new setting, “Measure conversions on customer devices,” adds a match on the shopper’s own device. Meta says it uses information already shared with the business, such as an email address, and temporary device information. It receives confirmation of a purchase and the campaign to credit. This recovers measurement; it does not create a second order or establish that the advertisement caused the sale.
Eligibility follows the shopper and the website. Meta’s setup requirements exclude people located in the EU and UK. The Pixel must run directly on the page, rather than inside an embedded page or as an image-only tracker. The website must require account login with an email address or mobile number. A merchant’s headquarters alone therefore does not determine eligibility. Advertisers can review each Pixel in Events Manager, the tracking control panel: choose Data sources, select the Pixel, open Settings and find the device-measurement toggle. It defaults to on for eligible Pixels and can be switched off anytime.
Existing tracking stays in place. Meta’s help page says the feature works alongside the Pixel and the Conversions API, its server connection for sending website events. The period and rule used to give ads credit remain unchanged. Dated notice coverage places the gradual start on November 12; the help pages do not repeat that date. They also leave important implementation details unresolved, including purchase-value treatment and how this new route avoids counting the same order twice. Meta promotes a stronger signal, but the inspected material does not establish exactly how recovered purchases enter bidding.
MarketMaze Take: A more complete count can be useful and still make a campaign comparison misleading. At unchanged advertising spend, adding credited purchases lowers reported cost per purchase by arithmetic. That improvement says something about the report. It does not, by itself, say the advertising generated additional demand.
Preserve a comparable baseline. Save purchase reports before the change and keep their crediting period consistent. Compare them with paid orders in the shop’s own records. A widening gap flags a measurement question; it does not automatically prove either inflated reporting or better advertising. Avoid changing several tracking settings at once and then assigning all movement to this feature.
Separate accuracy from persuasion. A correctly matched order could still have happened without the ad. Testing additional sales needs a comparable group that does not see the advertising, rather than a higher platform count alone. For merchants selling across regions, separate shopper markets before comparing results: the EU and UK exclusion means the same measurement change does not apply to every customer.
