Frequently Asked Questions
What are UTM parameters?
Tags added to a URL (utm_source, utm_medium, utm_campaign, etc.) that let analytics tools like Google Analytics track exactly where your traffic came from.
Which fields are required?
Source, medium, and campaign name are the essentials most analytics platforms expect — term and content are optional, typically used for paid search keywords or A/B testing specific ad variations.
What's a good example of source and medium?
For an email newsletter, source might be "newsletter" and medium "email"; for a paid Facebook ad, source "facebook" and medium "cpc" or "paid-social."
Does this work with any website URL?
Yes, enter any valid URL and the UTM parameters are appended correctly, whether or not the URL already has other query parameters.
