Understanding the Storage of UTM Parameters and Referrers in Cookies

Ever wondered why UTM parameters and referrers are stored in cookies? Let's dive into the reasons behind this practice:

Why UTM Parameters and Referrers are Stored in Cookies:

Maintaining Campaign Attribution:

When users arrive at your website via a UTM-tagged link or from a specific referrer, it's essential to track the source of their visit. Storing UTM parameters and referrers in cookies ensures that this information persists as users navigate through your site or return at a later time.

Preserving Attribution Across Sessions:

UTM parameters are typically appended to URLs, but they can be lost when users navigate away from the landing page. By storing this information in cookies, you can maintain accurate campaign attribution even after the parameters have been removed from the URL.

Long-Term Tracking:

Cookies provide a means of long-term tracking, allowing you to attribute conversions or interactions to specific marketing campaigns over an extended period. The "_poper_m" cookie, lasting for 365 days, ensures that attribution data remains accessible for an extended duration.

Overwriting Old Parameters:

The cookie is designed to overwrite old parameters with new ones if they are present. This ensures that the stored information remains up to date and reflects the most recent source of user traffic.

Resetting UTM Tags or Referrers:

If you're testing Poper or need to reset the saved UTM tags or referrer, you can delete the site cookies associated with "_poper_m." This action will clear the stored parameters, allowing you to start fresh with new attribution data.
