UTM Builder

Untagged links are invisible in analytics — traffic lands in 'direct' and your campaign learnings evaporate. This UTM builder assembles campaign URLs with proper encoding and parameter order, so every newsletter, social post, and partnership is attributable.

— fill in the fields above —

Adopt a naming convention before you scale: lowercase everything, hyphens not spaces, consistent source/medium taxonomy (newsletter/email, x/social). Consistency is what makes reports readable a year later.

How to Use the UTM Builder

  1. 1Paste the destination URL.
  2. 2Fill utm_source (where), utm_medium (how), utm_campaign (why).
  3. 3Optionally add term and content for ad/variant detail.
  4. 4Copy the final URL — test it once before mass sending.

Frequently Asked Questions

What do source, medium, and campaign mean?
source = the referrer (newsletter, x, partner-site); medium = the channel type (email, social, cpc); campaign = the initiative (spring_launch). GA4 groups traffic by these exact values.
Should UTM values be lowercase?
Yes — analytics tools are case-sensitive, so 'Email' and 'email' split into two rows. Lowercase everything, always.
Should I use UTMs on internal links?
Never — internal UTMs reset the visitor's session and misattribute the original source. Use them only on links from external properties into your site.
