Apptrian Facebook Pixel Extension for Magento adds Facebook Pixel with Dynamic Ads code on CMS pages (including home page), category pages, product pages, catalog search pages, catalog advanced search pages, customer registration page, checkout page (default Magento one but also can be made compatible with others - this will require small changes in code), checkout success page, and wishlist page.
Optionally Facebook Pixel block can be added to any other Magento page or any other extension page (blogs, form pages, etc.) via xml layout updates. The Facebook pixel allows you to place a single pixel on your entire website to report conversions, build audiences and get rich insights into how people use your website.
Conversion measurement lets you track actions people take after viewing your Facebook Ads across multiple devices, including mobile phones, tablets, and desktop computers. By creating a Facebook pixel and adding it to the pages of your website where conversions happen, like the checkout page, you will see who converts as a result of your Facebook Ads. The pixel will continue to monitor the actions people take after clicking on your ad. You can see which device they saw the ad on and which device they ultimately converted on.
To use this extension, a free Facebook Business Manager account is required.
