A pixel is a small piece of tracking code added to a website to collect data about visitor actions. Social platforms and ad networks use pixels to understand how users behave after clicking or viewing an advert, such as completing a purchase, submitting a form, or visiting key pages. This data supports conversion tracking, audience building (remarketing), and optimisation, helping platforms learn which users are most likely to take valuable actions. Pixels need correct implementation and consent settings where required, and they should be tested to ensure events are firing accurately.
