Why it matters

Why you need a UTM builder

Without UTM tags, analytics tools like GA4 lump visitors into generic "Direct" or "Referral" buckets. That makes it impossible to know which specific ad, email, or post drove a sale. UTM (Urchin Tracking Module) parameters label each link so every click lands in the right report.

Best practices for naming

  • Lowercase only: GA4 is case-sensitive, so Email and email show up as two rows. This builder lowercases for you.
  • No spaces: URLs can't contain spaces. Spaces are swapped for underscores automatically.
  • Stay consistent: Don't switch between facebook and fb. Pick one convention and stick to it.

Once your links are clean, the next question is which ones actually pay off. Zyro's revenue attribution connects these UTMs to real sales. Compare plans on the pricing page, or browse more free marketing tools.

Questions

UTM tagging, answered

What is the difference between Source and Medium?

Source is where the traffic comes from (e.g. google, tiktok). Medium is how it arrived (e.g. cpc, email, social).

Does this work for TikTok Ads?

Yes. For TikTok, use utm_source=tiktok and utm_medium=cpc (or paid_social) so GA4 categorizes the traffic correctly in your Acquisition reports.
