    The page people should land on, e.g. your product or landing page.

    Choose where the link will be used. Source and medium fill in for you; add a campaign name.

A simple naming rule that keeps reports clean

Pick one way of writing each tag and stick to it. A simple rule that works for most businesses:

  • Source is the platform: facebook, instagram, google, newsletter.
  • Medium is the type: paid_social for ads, social for unpaid posts, cpc for search ads, email for email.
  • Campaign is the offer and month: shopify-october, eid-sale-2026.
  • Content tells ads apart: video-1, carousel-a.

With this rule, GA4's default channel report puts your ads under Paid Social and your posts under Organic Social, without any extra setup.

Questions about this tool

What are UTM tags?

Small labels added to the end of a link (utm_source, utm_medium, utm_campaign and so on). Google Analytics reads them, so you can see which ad, post or email sent each visit.

Do I need UTM tags on Google Ads links?

Usually not. If your Google Ads account is linked to GA4 with auto-tagging on, Google adds its own click ID. Use UTM tags for Google Ads only if auto-tagging is off.

Why does the tool make everything lowercase?

GA4 treats "Facebook" and "facebook" as two different sources, which splits your reports. Lowercase with dashes keeps them together.

Can I tag a WhatsApp wa.me link?

No. Tag links that go to your website. WhatsApp does not pass UTM tags on, so they do nothing on a wa.me link.
