Put it into practice

Preflight referral links before a campaign

A malformed URL can fragment analytics or remove the identifier used for referral attribution. This checker reviews the URL itself for common mistakes without visiting the destination or sending the link to a server.

The result is a syntax and tracking-readiness review. It cannot confirm that a destination installs cookies, preserves parameters across redirects, or records conversions correctly. Use Refport's test workflow for end-to-end attribution verification.

Common affiliate link problems

Check the exact URL partners will receive, including all query parameters and fragments.

A missing partner or referral identifier
Duplicate parameters with conflicting values
Spaces or inconsistent capitalization in UTM values
Non-HTTPS destinations
Very long URLs that are difficult to share reliably

Questions, answered

About the referral link checker

Does the checker visit my URL?+

No. It parses the text locally in your browser and does not request the destination.

Can it verify referral cookies?+

No. Cookie and conversion verification requires an end-to-end test on the destination site. This free checker focuses on URL structure and tracking parameters.

Which referral parameters are recognized?+

The checker recognizes common names such as ref, via, affiliate, aff, partner, and referral, as well as standard UTM parameters.
