Referrer-Policy

🛠️ What is Referrer-Policy?

Referrer-Policy is an HTTP header that controls how much referrer information (the URL of the previous page) is included with requests made from your site. It plays a crucial role in both privacy and data analytics in SEO.

⭐ Why is Referrer-Policy Important in SEO?

Setting a Referrer-Policy affects how much context website owners have for incoming traffic. It can help balance the need for privacy with the benefits of data analytics for SEO. Proper configuration ensures you're able to optimize for site performance without over-sharing user data.

⚙️ How Does Referrer-Policy Work?

1. A user navigates from Site A to Site B.
2. Site A has a Referrer-Policy header set, controlling the amount of information Site B receives.
3. Based on the policy, Site B will receive a full, partial, or no URL from Site A.
4. The policy can influence analytics data and user privacy management.

📌 Examples of Referrer-Policy Types

• 'no-referrer' – No referrer information is sent with the request.
• 'no-referrer-when-downgrade' – Default policy, sending referrer on same-protocol requests.
• 'origin' – Only the origin is sent as referrer.
• 'strict-origin-when-cross-origin' – Sends full URL for same-origin, and only origin for cross-origin.

✅ Best Practices for Referrer-Policy

• Choose the least restrictive policy that meets your privacy requirements while still aiding analytics.
• Consider user privacy and data protection laws when selecting a policy.
• Test the impact of different policies on your analytics and referrer data.
