UTM Builder
FreeAvailable on all plans
What is the UTM Builder?
UTM parameters are query string tags appended to your destination URL that analytics platforms like Google Analytics, Plausible, and Fathom use to attribute traffic to specific campaigns. The AWSYS.CO UTM Builder generates and attaches these parameters to your destination URL before shortening, keeping your short link clean while the full UTM-tagged URL remains hidden from visitors.
Requirements
The UTM Builder is available on all plans. Your destination site must have an analytics tool that reads UTM parameters. The five standard parameters are utm_source, utm_medium, utm_campaign, utm_term, and utm_content.
Step-by-step: Build a UTM-tagged link
- Open Create Link and paste your destination URL.
- Click UTM Parameters to expand the builder section below the destination field.
- Fill in Source (e.g.,
newsletter), Medium (e.g.,email), and Campaign (e.g.,spring-2026). These three are most important. - Optionally fill in Term (for paid keyword tracking) and Content (to distinguish multiple links in the same campaign).
- The preview field below the UTM section shows the full destination URL with parameters appended so you can verify it looks correct.
- Click Shorten. Visitors clicking the link are redirected to the UTM-tagged URL, and your analytics tool records the source, medium, and campaign automatically.

Common questions
Do the UTM parameters appear in the short link?
No. The short link stays clean (e.g., awsys.co/a1b2c3). The UTM parameters are appended to the destination URL that the visitor is redirected to, so they only appear in the browser address bar after the redirect.
Can I set UTM parameters via the API?
Yes. Pass "utmSource", "utmMedium", "utmCampaign", "utmTerm", and "utmContent" in the POST /api/createShort request body. They are appended to the destination URL automatically.
What if the destination URL already has query parameters?
AWSYS.CO appends the UTM parameters with a & separator, preserving existing query parameters. Ensure there are no conflicts with parameter names already in the destination URL.
Are UTM values case-sensitive?
Yes. Google Analytics treats Email and email as different values. Use a consistent, lowercase naming convention across all your campaigns to avoid split reporting.
