Worked example: tagging a pricing-page link in a newsletter
Illustrative input: a link to https://example.com/pricing from a newsletter, with source newsletter, medium email, campaign spring_launch and content header_button. This is an invented campaign.
- The tool outputs https://example.com/pricing?utm_source=newsletter&utm_medium=email&utm_campaign=spring_launch&utm_content=header_button.
- Left-blank optional fields (term here) are simply left out of the link.
- In your analytics, visits through this link are grouped under the newsletter source and email medium instead of landing in direct traffic.
What to do next: Write down your naming convention (lowercase, underscores, one spelling per source) and reuse it, because analytics treats Email and email as different values.

Builders like this are simple, deterministic, client-side utilities — no AI call, no server cost per use. Charging credits for them was never justified, so they're free and instant. With the UTM Builder, you get this without paying per generation or hitting a credit wall.

Frequently asked questions
Is the UTM Builder free?
Yes. Every one of GrowthGadgetAi's 100+ Marketing Toolkit tools, including the UTM Builder, is completely free with unlimited use — no credits, no plan requirement and no credit card.
Do I need to create an account to use it?
You need a free GrowthGadgetAi account so your output and history are saved, but signing up costs nothing and never requires a card.
Does the UTM Builder store what I generate?
The UTM Builder runs in your browser. Copy or download your result before navigating away if you want to keep it.
What happens if I get UTM parameters wrong?
Inconsistent casing or naming (e.g. "Email" vs "email", "Q1-promo" vs "q1_promo") splits what should be one campaign into several rows in your analytics. Keep a consistent naming convention across every link you tag.
How do I use the UTM Builder?
1) Open the UTM Builder. 2) Fill in your details. 3) Copy or download the result. The whole process takes about a minute and runs on this page, on desktop or mobile.
What can I use the UTM Builder for?
Common uses: marketers preparing campaign assets; developers and marketers needing a quick utility; agencies producing client-ready deliverables.
Which UTM parameters are required?
Source, medium and campaign are the three that matter for most reports. Term and content are optional and are used to tell paid keywords or different links in the same campaign apart.
Should I put UTM links on links inside my own website?
No. UTM parameters on internal links can overwrite where a visit really came from. Use them only on links placed outside your site, such as email, ads and social posts.
