# UTM Campaign Builder: Common Mistakes and Best Practices

Most problems with uTM Campaign Builder aren't caused by not knowing what to do — they're caused by small, easy-to-miss mistakes that compound quietly over time. Here are the ones that come up most often.

Mistake 1: Letting every team member invent their own naming convention, which fragments campaign reporting into dozens of near-duplicate rows.

Mistake 2: Using inconsistent capitalization or spacing ('Email' vs 'email' vs 'e-mail'), which most analytics tools treat as entirely distinct values.

Mistake 3: Tagging a link once and never auditing old UTM parameters, letting outdated or mistyped campaign names accumulate in historical reports indefinitely.

The fix for most of these isn't more effort, it's a regular check. A few habits that prevent them from creeping back in:
- Keep a shared log of every UTM combination created, so nobody accidentally creates a near-duplicate variant that fragments reporting.
- Avoid tagging internal links with UTM parameters — it can incorrectly reset session attribution in some analytics setups, misreporting the original traffic source.

Worth reading alongside this: our guide to SEO-friendly URL slugs, which covers the adjacent side of the same part of a technical SEO audit.

UTM Campaign Builder catches most of this automatically, which is the easiest way to stop these mistakes from shipping in the first place.
