What this utm builder does

UTM Builder appends the five standard campaign parameters to a destination URL: source, medium, campaign, term and content. Analytics tools use these values to attribute sessions to a channel, and consistency matters more than any clever naming convention.

The builder warns when source, medium or campaign is missing, because those omissions produce the dreaded “(not set)” rows in reports. It also parses an existing tagged URL so you can check what a colleague sent before using it.

Why use it

  • Tag newsletter, social and paid links with one naming scheme.
  • Catch missing parameters before a campaign goes live.
  • Inspect an existing link to see why it appears under the wrong channel.

How to use it

  1. 1Paste the destination URL.
  2. 2Fill in source, medium and campaign; add term and content only when they add information.
  3. 3Copy the tagged URL and use it everywhere that placement appears.

Worked examples

Newsletter link

Input

https://example.com/tools/ · source=newsletter · medium=email · campaign=november

Output

https://example.com/tools/?utm_source=newsletter&utm_medium=email&utm_campaign=november

Two placements

Input

Same campaign, content=header and content=footer

Output

Two URLs that differ only in utm_content, so you can compare placement performance.

Common mistakes

  • Using different spellings such as email, e-mail and Email, which split one channel into three.
  • Tagging internal links, which starts a new session and overwrites the original attribution.
  • Putting UTM parameters on links inside an email to your own site when the platform already tags them.

Frequently asked questions

Are UTM parameters case-sensitive?
Analytics tools generally treat values as case-sensitive. Pick lowercase and stay consistent.
Do UTMs affect SEO?
They create duplicate URLs for crawlers but do not change rankings when canonical tags are correct. Do not use them on internal navigation.
What is the difference between source and medium?
Source is the specific origin, such as a newsletter name. Medium is the channel type, such as email or cpc. Reports group by medium and break down by source.
