Why do I see "Blank" or "Unknown" Referring URLs in my reports?

Blank or unknown referring URLs occur when browser privacy settings, security protocols (HTTPS to HTTP), or mobile app redirects prevent the transmission of source data. This is a standard industry occurrence and does not affect the accuracy of your tracking or commissions.

Common Causes for Missing URL Data

Understanding why the source page is sometimes hidden:

• Security Protocols: If a user moves from a secure site (HTTPS) to a non-secure site (HTTP), browsers automatically strip the referring URL to protect user privacy.
• Privacy Tools: VPNs, ad-blockers, and "Incognito" browser modes are designed to block referrer headers.
• Mobile Apps: Clicks originating from within apps (like Instagram or Facebook) often do not pass the original URL data through their internal browsers.

Resolution: Is my tracking still working?

• Commissions are Safe: Referring URLs are for your information only. They are not required for tracking sales or paying commissions.
• Tracking Method: Skimlinks tracks conversions via cookies placed in the user's browser, not via the referring URL header.
• Verify via Click Data: If you see revenue and clicks in your reports, your Skimlinks integration is working perfectly, even if some individual URLs are marked as "Unknown."
