What is a UTM link?
A UTM link is a normal URL with campaign tracking parameters appended: utm_source, utm_medium, utm_campaign, and optional utm_content and utm_term. Analytics tools (Google Analytics 4, Plausible, etc.) read these tags to attribute sessions to Instagram, email, paid ads, or a specific campaign name.
This free UTM link builder merges your base URL and tags in the browser. Copy the result into bio links, newsletters, or scheduled posts, no spreadsheet required.
UTM naming best practices
Keep names lowercase with underscores or hyphens (spring_launch, not “Spring Launch!”). Use utm_source for where the click happens (instagram, newsletter, facebook), utm_medium for the channel type (social, email, cpc), and utm_campaign for the initiative (product_launch, black_friday).
Optional utm_content distinguishes two links in the same post (carousel_slide_2, cta_button). utm_term is mainly for paid search keywords. Consistent naming makes GA4 reports usable months later.
- Presets fill common source/medium pairs, adjust campaign before copying.
- Always use HTTPS in the destination URL when your site supports it.
- Test the generated URL in an incognito window to confirm the page loads.
