UTM builder
Campaign tags that merge, not clobber
Add UTM parameters to a code’s destination and redireo folds them into the URL at scan time — keeping any query parameters your link already carries, so attribution lands without breaking the destination.
What does the UTM builder do?
It attaches standard campaign parameters to a code’s destination so scans show up correctly in the analytics you already run. Instead of hand-appending ?utm_source=… to every link and hoping you got it right, you set the tags on the code once and every scan carries them.
What if my URL already has query parameters?
They survive. redireo merges the UTM parameters with the existing query string rather than replacing it. If your destination already depends on a parameter — a product id, a locale, a session hint — that value is kept, and the campaign tags are added next to it. Nothing you relied on gets silently dropped.
When are the parameters applied?
At scan time, during the redirect. The scanner arrives at your destination with the merged query string in place, so tools like Google Analytics attribute the visit to the right source, medium and campaign without any manual link editing per placement.
Which parameters are supported?
The five standard UTM fields: source, medium, campaign, term and content. Those cover what mainstream attribution tools read, so a redireo code drops straight into reporting you already have.
UTM builder questions
What does the UTM builder do?
It attaches campaign parameters — utm_source, utm_medium, utm_campaign and the rest — to a code’s destination so your existing analytics attribute scans to the right campaign. You set them once on the code and every scan carries them through.
What happens to query parameters already on my URL?
They are preserved. The UTM builder merges its parameters with whatever is already on the destination URL rather than clobbering it. A parameter your link already relies on stays intact, and the campaign tags are added alongside it.
When do the parameters get applied?
At scan time, on the redirect. The scanner is sent to your destination with the merged query string, so your downstream analytics see the UTM tags on arrival without you hand-editing every link.
Which parameters can I set?
The five standard UTM parameters — source, medium, campaign, term and content. Those are what Google Analytics and most attribution tools read, so the codes slot into reporting you already run.
