Build trackable campaign links for GA4
Paste your landing page URL, add your source, medium and campaign, and this UTM builder assembles a properly encoded, GA4-ready link instantly — right in your browser. Nothing is uploaded or stored.
Consistent UTM tagging is what makes your Google Analytics campaign reports trustworthy. Keep values lowercase and use a fixed vocabulary (e.g. always email, never Email) so your data stays clean.
Frequently asked questions
What is a UTM parameter?
UTM parameters are tags you add to a URL so analytics tools like Google Analytics 4 can attribute a visit to a specific campaign, source and medium. Example: ?utm_source=newsletter&utm_medium=email&utm_campaign=spring_sale.
Which UTM parameters should I use?
utm_source, utm_medium and utm_campaign are required for clean reporting. utm_term and utm_content are optional and mostly used for paid search and A/B testing different creatives.
Is this UTM builder free?
Yes. It runs entirely in your browser, stores nothing, and there's no signup or watermark. It's one of several free tools by TheDock.
Does it work with GA4?
Absolutely. GA4 reads the same utm_* parameters, so links you build here populate Traffic acquisition and Campaign reports automatically.
