A referrer is the web address that sent a visitor to a page. Analytics tools read it to show which sites and apps bring traffic.
When you click a link, your browser usually tells the next site where you came from, in a header called Referer. The header is spelled with one r, a typo kept from the original HTTP standard.
Referrers are often incomplete. Many apps open links in an in-app browser that sends no referrer, and sites can limit what they share with a referrer policy. Visits with no referrer show up as direct traffic.
This gap is one reason UTM parameters exist. A tag in the URL survives when the referrer does not.
Example
A blog's analytics shows 300 visits from t.co, the address X uses for links in posts. The blogger knows a post on X sent those readers.
In pageo
Turn on UTM tags in pageo settings to label the visits your page sends to other sites, even when an app hides the referrer.
