UTM Parameters
UTM parameters tag URLs with source, medium, and campaign so analytics knows where visits came from.
What UTM parameters are
UTM parameters are tags appended to URLs that tell analytics where a visit came from: utm_source, utm_medium, and utm_campaign as the core trio, with utm_term and utm_content for finer detail.
Why UTM parameters matter
Untagged links melt into “direct” traffic: the newsletter click, the influencer’s bio link, and the QR scan all lose their identity without UTMs. Consistent tagging is what makes channel and campaign reporting mean anything.
Using UTMs without making a mess
- A naming convention: lowercase, no spaces, agreed values
- Source = where, medium = how, campaign = why
- A shared sheet or builder so the team tags identically
- Never on internal links: UTMs on your own navigation overwrite sessions
Frequently asked questions
Why does UTM discipline matter so much?
Because “Email,” “email,” and “newsletter” become three different channels in reports: analytics groups by exact string. One convention documented beats every clever variation.
Where do stores forget to use UTMs?
The unglamorous links: email footers, social bios, QR codes, packaging inserts, partner mentions. The campaign links get tagged; the evergreen links leak identity all year.
