UTM Campaign URL Builder
Add source, medium, campaign, and optional term/content parameters to any URL to build a properly tagged campaign tracking link.
These parameters are how Google Analytics and most other tools tell a genuine campaign click apart from organic or direct traffic. Keep source/medium/campaign values consistent (same casing, same spelling) across every link in one campaign, GA treats "Newsletter" and "newsletter" as two different sources and will split your numbers between them.
Frequently asked questions
Do I need all five UTM parameters?+
No, source, medium, and campaign cover the vast majority of use cases. Term and content are optional, mainly useful for differentiating paid search keywords or A/B testing different versions of the same ad or link.
Why does capitalization matter for UTM values?+
Google Analytics and most other tools treat UTM parameters as case-sensitive strings, so "Newsletter" and "newsletter" get tracked as two separate sources. Pick a casing convention (lowercase is the common default) and stick to it across every link in a campaign.
Will UTM parameters break the destination page?+
No, they're just additional query parameters most pages ignore entirely. The one thing worth checking: if the destination page has its own canonical tag logic, make sure it points to the clean URL without the UTM parameters, so search engines don't index the tagged version.
