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'll 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.
Tracking a conversion means keeping track of the visits to a specific page of the website. This is usually the page people visit after they have completed what you want them to do.
