# UTM link checker

Paste campaign links to check their UTM tags: missing or misspelled parameters, capital letters, redirects that drop the tags, and which GA4 channel each link lands in. Free, no signup.

## What the checker looks for

- **Missing tags.** Without `utm_source` and `utm_medium`, visits can't be credited to a source, and GA4 files them under Unassigned.
- **Typos.** `utm_campain` or `utm-source` are ignored by every analytics tool.
- **Capitals and spaces.** Tags are case-sensitive, so `Facebook` and `facebook` show up as two sources.
- **Tags after the #.** Anything after `#` isn't sent to the server or read as a tag.
- **Redirects that drop tags.** Some redirects (http to https, adding www, a trailing slash) lose the query string. The checker opens each link and compares the final address.

## Which GA4 channel will it land in?

GA4 groups visits into channels using `utm_medium` and `utm_source`. The checker follows Google's default channel rules: `email` lands in Email, `social` in Organic Social, `cpc` with source `google` in Paid Search. A made-up medium like `newsletter-link` lands in Unassigned, where nobody looks.

## Questions

### Which utm_medium values should I use?

Stick to the standard ones: email, social, cpc, paid_social, display, affiliate, referral and organic. Analytics tools group those into channels automatically.

### Is my link sent anywhere?

The tag checks run in your browser. If you tick the redirect check, each link is opened once from our server to see where it ends up; nothing is stored.

### Why do my campaign visits show as direct?

Usually a redirect dropped the tags, or the link was opened from an app that strips them. Run the link through this checker to see which.
