What is a referrer?

When someone clicks a link, the browser can tell the target site which page the click came from. That page is the referrer. Search engines, social networks, newsletters and other websites all show up as referrers.

Visits without a referrer are usually grouped as direct traffic. Privacy settings and referrer policies can hide the source, so referrer data is never perfect.

Why Referrer matters

  • It shows which sites and channels bring visitors.
  • It helps you decide where to invest in content and partnerships.

Practical tips

  • Tag campaign links with UTM parameters for more precise sources.
  • Watch for new referrers, they can point to mentions or backlinks.
