When the Facebook pixel tracking is implemented on you website, two cookies is set:
- "_fbp" is used to distinguish and keep track of your unique users
- "_fbc" is only set when a user arrives at your website from an Ad and the destination URL includes the click identifier "fbclid"
Both cookies are auto updated/extended by Facebook with a default expiration of 90 days. As auto update/extend can not be disabled, backup cookies will be required. This is the default setting of Cookie Saver.
Configuration to be added with the Cookie Saver installation:
acq("addCookie", {
"name": "_fbp",
"expirationDays": 90
});
acq("addCookie", {
"name": "_fbc",
"expirationDays": 90
});
