Which UTM parameters are required?

utm_source, utm_medium, and utm_campaign are the core three. utm_term, utm_content, and utm_id are optional.

Are UTM values case-sensitive?

Yes. Google Analytics treats Email and email as different values, so the builder lowercases values by default to keep reports clean.

Should I use UTM links on my own website?

No. UTM tags on internal links overwrite the visitor's original source. Use them only on links from external campaigns such as emails, ads, and social posts.
