UTM Campaign URL Builder

What Is the UTM Campaign URL Builder?

This tool appends the 5 standard UTM (Urchin Tracking Module) parameters to any URL, the standard Google Analytics convention for tracking which campaigns, sources, and mediums drive traffic.

How to Use This Tool

Enter your website URL and any of the 5 UTM fields (source and medium are the most commonly required). The tagged URL appears instantly.

The UTM Parameters

What the Builder Does to Your URL

The base address you enter is parsed as a full URL, so it must include a scheme such as https://; a bare domain like example.com is reported as invalid. Each UTM field you fill in is then set as a query parameter. Empty fields are skipped entirely. If the address already contains a parameter with the same name, for instance an existing utm_source, the new value replaces it rather than adding a duplicate. Any other query parameters already on the link are left in place, and a fragment such as a section anchor stays at the end.

Values are encoded automatically. A space in a value becomes a plus sign in the resulting link, and characters such as an ampersand or accented letter are percent-encoded. That means you can type natural text, but you should still prefer clean, simple values for reporting.

Worked Example

Suppose you send a spring newsletter linking to https://example.com/offers. You enter source as newsletter, medium as email, and campaign as spring_launch, leaving the rest blank. The result is https://example.com/offers?utm_source=newsletter&utm_medium=email&utm_campaign=spring_launch. If you later run two button variants in the same email, you can fill utm_content with button_top for one link and button_bottom for the other, and analytics can separate their clicks.

Naming Conventions That Save You Later

• Pick lowercase and stick with it. Analytics reports usually treat Email and email as different values, splitting one channel across two rows.
• Use underscores or hyphens instead of spaces, and use the same separator everywhere.
• Keep medium to a small set of stable values, such as email, cpc, social and referral, and put the specific detail in source and campaign.
• Keep a shared sheet of the values your team uses so different people do not invent new spellings for the same channel.
• Include an identifiable campaign name that will still make sense in a report a year from now.

Where Not to Use UTM Tags

Do not add UTM parameters to links that point from one page of your own site to another. In many analytics setups that starts a new session and overwrites the real original source of the visit, which corrupts your data. Reserve them for links placed on external channels you control, such as emails, ads, social posts, QR codes and partner placements. Also avoid putting personal information, such as an email address, in a UTM value, because the whole link can be seen, shared and logged.

Limits and Assumptions

The tool only builds the link. It does not verify that the page exists, shorten the link, or connect to any analytics account. It also does not enforce naming rules or warn about capitalization. How the values appear in reports depends on how your analytics platform is configured, so check its documentation. If people share your tagged link widely, the tags travel with it, so consider whether that attribution is what you want. The URL Parameter Remover on this site can strip them for a clean share.
