How the UTM Link Builder works
UTM parameters are tags added to a link so analytics tools such as Google Analytics can tell which campaign brought a visitor. Enter the page URL and at least the source, medium and campaign name; the tool adds them as utm_source, utm_medium and utm_campaign, plus optional utm_id, utm_term and utm_content.
Parameters already in the URL and any #section are kept; old UTM values are replaced. Values are URL-encoded (a space becomes %20), and the tool warns about spaces and capital letters, because analytics reports treat “Email” and “email” as different values.
Examples
A URL that already has parameters
For https://example.com/p?id=7#reviews the UTM tags go after id=7 and before #reviews, so the page still opens at the reviews.
Frequently asked questions
Which UTM parameters are required?
Google Analytics can work with just utm_source, but source, medium and campaign together give reports you can compare, so the tool asks for all three. Term, content and ID are optional.
Should I use UTM tags on links within my own site?
No. Internal UTM links start a new session and overwrite where the visitor really came from. Use them only on links placed elsewhere: emails, ads, social posts, QR codes.
How do I keep campaign names consistent?
Agree on lowercase values with hyphens (spring-sale, not “Spring Sale”), keep a shared list of sources and mediums, and reuse them. Consistent names keep reports from splitting one campaign into several rows.
