Quick answer: UTM Link Builder
Normalize campaign tracking by appending utm_* query params without hand-editing ampersands.

Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- UTM Link Builder
- Build tracked campaign URLs with consistent UTM parameters.
Analytics tools key off consistent naming. Building URLs with a builder avoids broken encoding and mixed-case chaos in Looker Studio.
Append utm_source, utm_medium, utm_campaign, and optional content/term parameters to any valid HTTP(S) URL.
Inputs on this page: Landing Page URL, utm_source, utm_medium, utm_campaign. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use UTM Link Builder when you need a transparent utm link builder answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Landing Page URL and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Never UTMs on internal nav links - session attribution will skew.
- Stick to lowercase keys and hyphenated values as a team convention.
- Shorten links only after UTMs are final so you don’t cache the wrong params.
