Conversion tracking

Meta's pixel is adding events on its own. Should I turn off automatic events?

By The Tofu team ·

Turn it off if you already send your own Lead event; keep it only if you have no events set up. Since August 3, 2026, new pixel setups through Google Tag Manager ask whether Meta can use AI to "identify and add missing events from your website," and Meta's developer docs say Meta Ads Data Advisor pre-selects it. Once on, Meta keeps adding standard events, such as Lead, from site activity, and one it adds can become an ad set's conversion goal. The switch is in Events Manager: Datasets, your dataset, Settings, then Automatic events under Event setup.

As of October 2026.

What changed

BeforeNow
How events are foundThe pixel picks up actions from visitor activity and page information, with no code (as Meta's "About automatic events" page still puts it)Meta says "AI identifies" standard events, such as purchases or leads, and keeps adding them "based on your website activity"
New pixel setupNo question about automatic eventsSince August 3, 2026: through Google Tag Manager, a screen after setup asks, and you can decline. Through Meta Ads Data Advisor, the option is pre-selected, and suggested missing events (Purchase, Lead, AddToCart) are applied by default
Name of the switch"Track events automatically without code" (per Jon Loomer)"Automatic events," below Event setup in the dataset's Settings tab. Meta's developer docs still use the old name
Where you review themIn the Overview tab with your other events (per Jon Loomer)The Settings tab, where you can review detected events and manage each one. Data Advisor labels them "Auto-detected"

Meta's own pages don't fully agree. The Help Center says Google Tag Manager setups ask on a separate screen and you can decline, but doesn't say which answer is pre-selected. The Data Advisor docs say it's pre-selected there. Jon Loomer, who wrote about the new switch on September 1, 2026, read Meta's documentation as turning it on by default for any new pixel created on or after August 3. AdMake's October 2026 changelog, published September 27, says the answer is yes unless you untick it and cites the Help Center page, but that page, when we checked on October 26, didn't say so. The pages also name the menu differently: the Help Center's steps for the switch start from Datasets in Events Manager's left menu, while its "About automatic events" and test events pages say Data sources. Loomer also found the old "Track events automatically without code" switch still at the bottom of the Settings tab, so a pixel can show both. He kept the feature on himself, until Meta creates "erroneous events."

Meta says automatic events are deduplicated from events you set up yourself, and it recommends keeping them on. It doesn't say how it decides that two events are the same.

Who it affects

  • New pixels. Anyone who set up a pixel through Google Tag Manager or Data Advisor since August 3, 2026 and didn't decline or untick the option. Meta says it is "gradually adding this feature to more new Pixel setup experiences over time."
  • Older pixels. Meta's pages don't say the feature was turned on for existing pixels, and Jon Loomer reports his older pixels had it off. Check anyway, because the switch can be turned on at any time.
  • B2B lead gen most of all. If your Leads campaigns optimize for a website Lead event, every extra Lead changes what Meta optimizes toward. Meta defines Lead as "a submission of information by a customer with the understanding that they may be contacted at a later date by your business," such as a form or a trial signup. By Meta's own definitions, signing up for an email subscription is Complete registration, and a phone, email or chat contact is Contact. Meta doesn't say how its AI tells these apart, so check what it labels as Lead.
  • Who can mostly ignore it. If you only run Instant Forms and don't use website events for optimization or audiences, the switch matters less, because Instant Form leads are submitted on Meta, not on your site.

What to do now

  1. Check the switch. Go to Events Manager, click Datasets in the left menu (some Meta pages call it Data sources), select your dataset, click Settings, and look for Automatic events below Event setup. Then scroll to the bottom of the tab for Track events automatically without code: Jon Loomer found that older switch still there, and Meta's developer docs still use its name. Check both.
  2. See what it added. Review the list of detected events in the Settings tab. In the Meta Ads Data Advisor browser extension, events Meta found this way show the status Auto-detected. Then open the Test events tab, enter your site URL, click Open website, and submit your own form. Watch which events fire; you can filter by activity type, including automatically logged pixel events.
  3. Compare Lead with your CRM. Put Events Manager's Lead count for the last 30 days next to the form submissions in your CRM for the same days. If Meta counts many more, find the pages or buttons that fire the extra ones.
  4. Turn it off if you already send your own events. If your Lead event comes from pixel code, the Conversions API or a partner integration, switch automatic events off so Lead means one thing. Keep it on only if you have no events set up and no time to add them, which is the case Meta built it for.
  5. Define Lead yourself without code, if you need to. Create a custom conversion: in Events Manager, click Custom conversions, then Create custom conversion. Pick your data source, choose All URL traffic as the conversion event, pick Lead under Choose a standard event for optimization, and add a rule such as URL contains your thank-you page path. You can then select it as the performance goal for a campaign.
  6. Check the goal on live ad sets. Before an ad set optimizes for Lead, make sure the event behind it is your real form submission. If real leads are too few to optimize on, see what to optimize your Meta ads for when a B2B campaign gets only a few leads a week.
  7. Decide at setup on new pixels. Decline the automatic events screen, or untick the option in Data Advisor, if you want to review events by hand.
