What it means in plain language
The Facebook pixel, currently called Meta Pixel, is a measurement code that records selected user events on the website for the purposes of analytics, optimization and targeting of Meta ads.
Where it genuinely helps
The Meta pixel sends browser events to the advertising platform for measurement and audiences, subject to consent and device restrictions.
What to decide before acting
Define events and parameters, consent order, Conversions API deduplication and identifier retention policy.
How to tell whether it works
Review Events Manager, duplicates, signal loss, purchase values and any firing before consent.
