About the utm campaign builder
Consistency is the whole point
GA4 treats Email, email and E-mail as three different sources. A single inconsistent tag splits a campaign across three rows and quietly ruins a quarter of reporting. This tool lowercases and hyphenates automatically.
Which parameters to use
Source, medium and campaign are effectively required. Term is for paid keyword data. Content distinguishes variants of the same campaign — two buttons in one email, for instance. Use all five consistently or none of them will be trustworthy.
Never tag internal links
UTM parameters on internal links start a new session and overwrite the original attribution. It is one of the most common ways teams accidentally attribute organic traffic to themselves.
Questions
Do UTM parameters hurt SEO?
They can create duplicate URLs if tagged links are crawlable. Use canonical tags, and never place UTM parameters on internal navigation.
What is the difference between source and medium?
Source is where the traffic came from (newsletter, linkedin, partner-site). Medium is the type of channel (email, social, cpc, referral).
One page at a time is slow.
Aeologic runs these checks across every URL you own and tells you which twenty to fix first.
