How we fix your links
1. Question Mark Syntax
URLs only allow one ? to initiate parameters. We keep the first one and convert all subsequent ? marks into & to preserve your data structure.
2. Character Cleaning
Non-latin characters (like ñ or ç) are normalized and stripped to prevent "percent-encoding" mess in analytics. Spaces are replaced or removed based on your preferences.
⚠️ Important: Manual Review Required
If our tool detects more ampersands (&) than equals signs (=), we flag a syntax error.
Note: We do not automatically delete extra ampersands. Because we cannot programmatically determine which parameters are intentional and which are broken, these must be corrected manually to avoid losing campaign data.
