About automatic events

The Meta pixel receives information about the actions, or events, that take place on your website. Automatic events are actions that your pixel receives from your website that don't require you to add any additional code. Your pixel receives these actions through visitor activity and by using information about your web page to better understand context associated with these actions.
If you haven't used events before, with automatic events you can:
- Create an ad using the sales, leads or engagement objectives. Choose a conversion location (such as website or app), and choose a specific conversion event (such as a purchase) and see your return on advertising.
- Create custom audiences based on actions people take on your website, such as adding an item to their basket or making a purchase.
- Create a lookalike audience to find new people similar to your best customers to reach with your Meta ads.
You can see your metrics for events received when you go to Events Manager, click the Data sources tab, select your pixel and click the Overview tab. Total events can include automatic events and any events you have manually added to your website or created using another platform, such as a partner integration.
Automatic events are de-duplicated from any other events that you have manually set up. We recommend keeping automatic events on for better Meta advertising optimisation.
