5 Mistakes to Avoid in UTM Tracking

Accurate attribution is the holy grail of digital marketing. Yet, many teams struggle with messy UTM data. Here’s how to fix it.

1. Inconsistent Naming

"Email", "email", and "Newsletter" are three different mediums in GA4. Pick one and stick to it.

2. Using UTMs for Internal Links

Never use UTM parameters for links inside your own website. This resets the session and breaks your attribution.

3. Forgetting the Source

Every UTM link must have at least a utm_source and utm_medium.

4. Too Many Parameters

Keep it simple. Don't use utm_term and utm_content unless you're actually A/B testing or running search ads.

5. Manual Building Errors

Typos can kill your data. Use a tool like the LinkShort UTM Builder to ensure your links are perfectly formatted every time.
