“Leads campaigns need the Meta Pixel”
Sales and leads campaigns on Meta need the Pixel on your website.
To find people who buy or sign up, Meta needs to see those actions on your website. That is what the Meta Pixel does.
- Open Integrations → Tracking.
- Set up a Pixel for the ad account and add it to your website.
- Or change the campaign’s goal to Traffic, which doesn’t need one.
