What Are UTM Parameters and Why You Need Them
UTM parameters (Urchin Tracking Module) are tags added to the end of a URL. They tell analytics platforms — like Google Analytics 4 — exactly which channel, campaign, or ad brought a visitor to your site.
Without UTM tags, GA4 often labels traffic as (direct) / (none) — even when it actually came from a paid ad or email campaign. With UTM parameters, you get a complete picture of what drives results.

UTM Best Practices
- Always use lowercase. GA4 treats
Googleandgoogleas two different sources. Stick to lowercase across all parameters. - No spaces. Use underscores (
_) or hyphens (-) instead. Our tool encodes spaces automatically, but it’s best practice to avoid them. - Keep campaign names consistent. Adopt a naming convention like
product_sale_june2025and apply it across all channels. - Never add UTMs to internal links. UTM tags are for external traffic only. Applying them to internal links resets the session in GA4.
- Test the link before launching. Make sure it opens correctly and leads to the right landing page.
