About UTM Builder
The UTM Builder creates properly tagged campaign URLs for Google Analytics and other tracking tools. Enter your base URL along with utm_source, utm_medium, utm_campaign, and optional utm_term and utm_content values. It validates the URL, URL-encodes every value, appends only the fields you fill in, and gives you a clean link to copy in one click.
It's completely free with no sign-up, no limits, and no ads on your links. Everything runs entirely in your browser, so your URLs and campaign names never leave your device or touch a server.
Frequently asked questions
- Is the UTM Builder free to use?
- Yes, it's 100% free with no account, no sign-up, and no usage limits. Build as many tagged campaign URLs as you need.
- Is my data uploaded or stored anywhere?
- No. The tool runs entirely in your browser using JavaScript. Your base URLs, campaign names, and every parameter stay on your device and are never sent to a server or logged.
- What are UTM parameters?
- UTM parameters are tags added to a URL's query string (utm_source, utm_medium, utm_campaign, utm_term, utm_content) that let analytics tools like Google Analytics identify which campaign, channel, or ad drove a visit.
- Which UTM fields are required?
- Source, medium, and campaign are the standard trio most analytics platforms expect. Term and content are optional and only added if you fill them in. The builder appends only non-empty fields.
- Does it URL-encode special characters?
- Yes. Every value is automatically URL-encoded, so spaces, ampersands, and other special characters are safely escaped and your tracking link won't break.
- Can I add UTM tags to a URL that already has query parameters?
- Yes. The builder preserves any existing query parameters and hash fragment on your base URL and simply adds or updates the UTM values alongside them.
