Frequently asked questions
Which UTM parameters are required?
utm_source, utm_medium and utm_campaign are the core three. utm_term and utm_content are optional for keywords and A/B variants.
Should UTM values be lowercase?
Yes. Analytics treats “Email” and “email” as different sources, so the builder lowercases and hyphenates values by default.
