Referrer analysis examines the HTTP Referer header in server logs to understand where your traffic originates, which external sites link to you, and how users navigate within your site.

## What Is Referrer Analysis?

Referrer analysis is the examination of the `Referer` (sic) HTTP header recorded in server access logs. This header contains the URL of the page that linked to the requested resource. By analyzing referrer data, you can identify traffic sources, track internal navigation paths, and detect referrer spam.

## Why It Matters for SEO

Referrer data reveals which external sites send traffic to you — a proxy for backlink activity. It also shows internal navigation patterns: which pages do users visit before converting? Unlike analytics tools that rely on JavaScript, server-log referrer data captures referrers from bots and non-JS clients. Referrer spam (fake referrer headers designed to appear in your analytics) is also visible and filterable in logs.

## How to Analyze Referrer Data

Extract the referrer field from Combined Log Format entries. Group by domain to see top traffic sources. Filter out internal referrers (your own domain) to focus on external sources. Watch for referrer spam — domains you do not recognize sending suspicious volumes of traffic. [LogBeast](/logbeast/) provides referrer dashboards with automatic spam detection.
