We use your Referer to identify if our tracking links are located on your website. We may also share your Referer with our partners, such as affiliate networks and/or advertisers, upon your request.

No other information will be transferred to our partners. Read more about the Referer Policy in Section 4.3 of our Terms of Use

Main features of the Referer header:

The Referer contains the absolute or partial address from which the user requested the resource.
The Referer allows a server to identify referring pages users come from or where requested resources are used. You can use this data for analytics, logging, optimized caching, and more.
When users click a link on any page, the Referer contains the address of the page that includes the link.
TheReferer can contain an origin, path, query string, and may not contain URL fragments (i.e #section) or username:password information.
The request referrer policy defines the data that can be included in the Referer header.

The usage of the header increases the risk of privacy and security breaches on the website. It’s important to handle it with care. Read more

How to set Referer to your website

You can set referrer policies inside HTML. For example, you can set the referrer policy for the entire document with the <meta> tag with the name of referer:

<meta name="referrer" content="origin" />

There are many different types of content associated with the <meta> element. We are only interested in origin. For example, a document at https://example.com/page.html will send the referrer https://example.com/. Read more

Also, you can specify the referrerpolicy attribute for <a>, <area>, <img>, <iframe>, <script>, <link> tags to set referrer policies for individual requests:

<a href="http://example.com" referrerpolicy="origin">…</a>
