UTM Builder
Build consistent campaign links for Google Analytics 4 with UTM parameters.
How to use UTM Builder
- Paste the page URL you want people to land on.
- Fill in source, medium and campaign (and term/content if useful).
- Copy the finished link and use it in your email, ad or post.
How it works
UTM parameters tell analytics where a visit came from. Google Analytics 4 reads utm_source, utm_medium, utm_campaign, utm_term, utm_content and utm_id. Values are case-sensitive in reports, so "Email" and "email" become two different mediums; forcing lowercase keeps reports clean.
Existing query parameters and #fragments in your URL are preserved, and any old UTM values are replaced rather than duplicated. Use the medium names GA4 recognises (such as email, cpc, social, referral, affiliate) so traffic lands in the right default channel group.
Example
https://toolgix.com/merge-pdf/ with source newsletter, medium email, campaign november_launch becomes https://toolgix.com/merge-pdf/?utm_source=newsletter&utm_medium=email&utm_campaign=november_launch.
Frequently asked questions
Which UTM parameters are required?
Technically none, but always set source, medium and campaign, or GA4 reports will be hard to read.
Should I use UTM links on my own site?
No. Internal links with UTMs start a new session and overwrite the real source. Use them only on links from outside your site.
Do UTM parameters affect SEO?
Not if your pages have canonical tags pointing to the clean URL, which most sites do.
Is anything tracked by Toolgix?
No. The link is built in your browser; Toolgix does not shorten or redirect it.
Limitations
- Does not shorten links.
- Medium-to-channel mapping depends on your GA4 settings.
