Free UTM Link Builder

Add source, medium and campaign to any link so Google Analytics can show exactly which channel and campaign brought each visit and enquiry. Presets keep your naming consistent.

Fill in the address, source, medium and campaign.

Use the same names every time (lowercase, underscores) so your reports do not split one channel into several.

A simple naming system

  • Source: the platform, for example facebook, google, newsletter.
  • Medium: the type, for example paid_social, cpc, email, social.
  • Campaign: the push, for example diwali_offer_2026.
  • Content: which version, for example video_a or button_blue.

Frequently asked questions

What are UTM parameters?

UTM parameters are tags added to a URL, such as utm_source, utm_medium and utm_campaign. Analytics tools read them to show where visitors came from and which campaign they clicked.

Which parameters are required?

Source, medium and campaign are the three that matter. Term (for paid keywords) and content (for telling ads or links apart) are optional.

Why should I use lowercase and underscores?

Analytics treats Facebook and facebook as different sources. Using one lowercase style with underscores keeps your reports clean.

Should I use UTMs on links inside my own website?

No. UTM tags on internal links can overwrite the real source of a visit. Use them on links that bring people to your site from elsewhere.

Where will I see the results?

In Google Analytics 4, under Reports → Acquisition → Traffic acquisition, with source, medium and campaign dimensions.
