UTM Builder

Key concepts

The UTM link builder appends query parameters so analytics tools can split traffic from ads, newsletters, and social. Values are encoded with encodeURIComponent. Source, medium, and campaign are the core three; term and content are optional. If the team does not standardize case and underscores, the same campaign splits into several rows.

If the base URL already has a query, check the final URL so question marks and ampersands do not double up. Do not put personal data in content. Generation happens only in the browser. If you use a short URL, the parameters must remain on the final destination for tracking to work.

Example

Put a landing in the base URL and generate with source google, medium cpc, and campaign spring_sale to get an address with those three parameters. Adding banner_a in content lets you split creative A/B. Paste the copied link into the ad creative URL as-is. If case and spaces are not fixed in team rules, the same campaign splits into several rows. If the base URL already has a query, check that question marks and ampersands are not duplicated in the final URL. Keep utm_content to a banner name so personal data does not go in. When trying the same input several times, reset and paste again so it does not mix with the previous output. On a shared computer, clear the fields when you finish so the original is not left on the monitor. Closing the browser tab also discards what you just pasted; you do not need to send a delete request to a server. Button names and field titles match the tool at the top of the screen, so you can follow along as you read. If the result is empty, first check that required fields are filled and that an error message is not hidden. This article is usage guidance and does not mean input is kept in external storage. On mobile, the copy button may ask for clipboard permission; allow it and press again.
