Build UTM links for GA4 and campaign tracking
UTM Link Builder adds utm_source, utm_medium, utm_campaign, utm_term, and utm_content values to a landing URL. Use it for newsletters, ads, social posts, affiliate links, and GA4 campaign attribution.
Useful For
- Add source and campaign values to newsletter CTAs
- Separate Google Ads, social, and affiliate traffic
- Copy a Markdown campaign link
Good To Know
Custom URLs and campaign values are not included in shared links. Example links store only the selected preset name.
Developer Check
Generated code, regexes, meta tags, and config snippets should be treated as drafts and tested again in your runtime, security policy, and deployment environment.

Yes. Add source, medium, campaign, term, and content values to a base URL for campaign tracking.
Entered values are URL-encoded, so spaces and non-English text can be included in the generated link.
Review the base URL, duplicate parameters, campaign naming rules, and the UTM conventions used by your analytics tool.
