A Facebook Pixel is a piece of code that can be placed on a website to track user interactions and visitor behaviour. It’s a tool provided by Facebook for businesses and advertisers who want to measure the effectiveness of their advertising by understanding the actions people take on their website.
When a user visits a website with a Facebook Pixel installed and takes an action (like purchasing a product), the pixel is triggered and records this action. This data allows businesses to track conversions, create targeted audiences for future ads (including retargeting campaigns), and remarket to people who have already taken some kind of action on the website.
The Pixel can also be used to track specific events, like which pages a user visited, whether they added items to a cart, if they initiated a checkout, and other valuable data. This can provide important insights and enable businesses to create more personalised and effective advertising campaigns on Facebook.
