Which UTM parameters are required?

utm_source is required for the tags to be recognised. utm_medium and utm_campaign are strongly recommended. utm_term, utm_content and utm_id are optional.

Should I use UTMs with Google Ads?

Keep Google Ads auto-tagging (gclid) switched on, as it passes richer data to GA4. Manual UTMs are mainly for other channels such as email, social, WhatsApp, influencers and print.

Should I add UTM tags to internal links?

No. UTMs on links within your own site start a new session and overwrite the original traffic source, which corrupts your reports. Use them only on links from outside your site.

Where do I see UTM data in GA4?

Go to Reports → Acquisition → Traffic acquisition and change the dimension to Session source / medium or Session campaign.

Why should UTM values be lowercase?

Analytics tools treat values as case-sensitive, so “Email”, “email” and “EMAIL” become three rows. Sticking to lowercase with underscores keeps reports clean.

About

About this tool

UTM parameters are small tags added to a link, such as utm_source=newsletter&utm_medium=email, that tell Google Analytics 4 and other analytics tools exactly where a visitor came from. Without them, clicks from WhatsApp, email, QR codes and many apps often show up as “direct” traffic, and you can't tell which campaign worked.

This builder creates correctly encoded campaign URLs as you type. Presets fill in sensible source and medium values for Google Ads, Meta ads, newsletters, WhatsApp broadcasts, LinkedIn and printed QR codes. Lowercase and space options keep your naming consistent, because UTM values are case-sensitive and “Facebook” and “facebook” are reported separately.

Need links for many pages or channels at once? Bulk mode combines every base URL with every source and exports a CSV. Each single link also gets a QR code for print, and your last 10 copied links are saved on this device so you can reuse or edit them later.
