# Facebook Pixel The [Facebook Pixel](https://www.facebook.com/business/learn/facebook-ads-pixel) makes it easy to track conversions and determine the ROI of your Facebook (FB) advertising campaigns. Enabling this extension adds the FB Pixel code blocks to the *\* of each page with the correct FB Pixel ID and event values. ![](/files/-LBRJ69opV8b4PQ9EKuE) ## Prerequisites You must [create/setup a FB Pixel](https://www.facebook.com/business/help/952192354843755?helpref=faq_content#createpixel) in your FB advertising account. Make sure you enable the *Lead event* during setup. Once setup, please \[Contact Support]\(doc:contact-support) and include the FB Pixel ID in your request. ## Helpful Notes * On all page loads (except Confirmation page) we fire the *Pageview* standard event. * On the Thank You (Confirmation) page the *Lead* standard event. * We do not *currently* support firing custom events/conversions. * A site can have 1 or more FB Pixels providing they are not duplicate FB Pixel IDs. * The FB Pixel only renders on production and Implementation URLs. It does NOT render on on-page editing URLs. ## Testing + Troubleshooting It is recommended that you test/validate that the FB Pixel is correctly functioning. You can easily accomplish this by using the [Facebook Pixel Helper chrome extension](https://developers.facebook.com/docs/facebook-pixel/pixel-helper). Once installed, you'll get details about which FB Pixel and event was fired. ![](/files/-LBRKTqxgOB6SArIrhCk) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
