UTM Checker

Paste one or more URLs to validate UTM parameters (utm_source, utm_medium, utm_campaign, etc.). This checker flags missing/empty required tags, duplicate parameters, casing issues, and values that should be encoded. It also generates a clean, normalized version of each URL—runs fully offline.

Category: SEO · URL: /tools/utm-checker.html
Checks: required UTM fields, empty values, duplicate keys, non-lowercase UTM keys, spaces in values, and outputs a normalized URL.

FAQ

What does a UTM checker do?

It parses UTMs in a URL and flags common tracking problems like missing required fields, empty values, duplicates, and inconsistent key casing.

Which UTM parameters are required?

Commonly required for clean reporting are utm_source, utm_medium, and utm_campaign; utm_term and utm_content are optional.

Does the order of UTM parameters matter?

Analytics tools typically don’t care about order, but a consistent order helps QA, deduplication, and team standards—this tool outputs a normalized order.

Why are duplicate UTM parameters bad?

If a URL contains the same key twice (e.g., two utm_source), different systems may read different values, causing inconsistent attribution.

Should UTM values be URL-encoded?

Yes—spaces and special characters should be encoded to avoid broken links or inconsistent parsing (e.g., use %20 instead of a literal space).

Does this tool send my URLs to a server?

No. It runs entirely in your browser and makes no network requests.

Can I check multiple links at once?

Yes—paste one URL (or query string) per line and the tool will validate and normalize each one.
