Tracker registry
Meta Pixel is a tracker owned by Meta. When a website embeds it, it collects pages you visit, button clicks, and form interactions on sites that embed it — tied to your Facebook/Instagram identity.
Pages you visit, button clicks, and form interactions on sites that embed it — tied to your Facebook/Instagram identity. Because the same tracker appears across many sites, Meta can stitch those signals into a profile tied to you — often without you ever visiting their app directly.
