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

Blank or unknown referring URLs occur when privacy settings, browser restrictions, or secure (HTTPS to HTTP) redirects prevent Skimlinks from capturing the exact source page of a click. This is a common industry occurrence and does not mean that your tracking or commissions are affected.

Common Causes for Missing URL Data

Understanding why the source page is sometimes hidden:

• Security Protocols: If a click moves from a secure site (HTTPS) to a non-secure site (HTTP), browsers automatically strip the referring URL for security.
• Privacy Tools: Ad-blockers, VPNs, and "Incognito" browser modes often block the transmission of referrer data.
• Social Media Apps: Clicks originating from within apps (like Instagram or Facebook) often show as "Unknown" because the app's internal browser does not pass referral headers.

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.
• Verify via Click Data: If you see revenue and clicks in your reports, your Skimlinks installation is working perfectly, even if some URLs are marked as "Unknown."
