URL inspector: parameters, UTM and gclid, fbclid, ttclid

How to inspect a URL

A broken campaign link throws no error: it just credits the sale to the wrong source. The inspector breaks any URL into readable parameters and flags the most common UTM slips before you publish the ad.

1. Paste the full link. It can come straight from the ad, the email or the browser bar. With or without https://.
2. Read the warnings. Errors come first, then warnings and info. Each one names the parameter involved and why it matters.
3. Check the parameter table. See the decoded value, the type (UTM, click identifier or other) and the platform behind each identifier.
4. Use the codec when needed. Paste a snippet to encode or decode percent-encoding, for example to read a value with %C3%A7 or to prepare a parameter with accents.

Everything is calculated here, in your browser. Nothing you type is sent to any server and we use no third-party cookies.

What the inspector checks

The analysis uses only the text you pasted, in your browser. No request is made to the URL, so the tool does not open the link or follow redirects.

These are the checks, in the order they appear in the report:

• Duplicate or conflicting UTMutm_source=a&utm_source=b → error; utm_source=a&utm_source=a → warning
• Uppercase, space and emptyutm_campaign=Summer%20Sale → uppercase and space
• Missing required UTMutm_source without utm_medium and utm_campaign → warning
• Fragmenthttps://site.com/#?utm_source=x → never reaches the server
• Click identifiersgclid, gbraid, wbraid, fbclid, ttclid, msclkid, twclid, li_fat_id, epik, yclid
