utm_content vs utm_term: when to use each
The two optional UTM tags get muddled constantly. utm_content distinguishes creatives or links for A/B comparison; utm_term carries the paid-search keyword. This page draws a clean line between them so each does its job and your reports stay legible.
What each tag is for
The two optional UTM parameters answer different questions, and keeping them in their lanes keeps reports readable:
- utm_content — which creative or link variant (A/B testing, header vs footer)
- utm_term — the paid-search keyword that triggered the click
- Three core tags (source, medium, campaign) stay required; these two are optional
Why conflating them breaks reports
utm_content is the A/B dimension: use it to compare two ad creatives, two button placements, or two post variants under the same campaign. utm_term is historically the paid-search keyword field, populated for search ads. If you put keywords into utm_content, your creative comparison fills with keyword noise; if you put creative labels into utm_term, your keyword report becomes meaningless.
The rule is simple: ask whether the value answers 'which version did they click' (utm_content) or 'which keyword brought them' (utm_term). Most non-search channels never need utm_term at all — leave it empty rather than repurposing it.
How it appears in analytics and logs
utm_content tells you which version of a link or creative was clicked; utm_term tells you which keyword triggered a paid-search click. Swapping them scatters keyword data into the content dimension and vice versa.
Diagnostic use case
Use utm_content to tell two creatives or links apart and utm_term for the paid-search keyword, so neither tag ends up carrying the other's data.
What WebmasterID can help detect
WebmasterID reads both utm_content and utm_term at ingest and keeps them as separate dimensions, so creative comparisons and keyword data do not bleed into each other in your reports.
Common mistakes
- Putting paid-search keywords into utm_content instead of utm_term.
- Repurposing utm_term as a second content field on non-search channels.
- Stuffing both a creative label and a keyword into one tag.
Privacy and accuracy notes
Keep both tags to generic labels — a creative slug or a keyword, never personal data. UTM values are public in the URL and logs.

UTM parameters are query-string tags you add to a link so analytics can attribute the visit to a campaign even when the referrer is missing. This page explains the five tags, a consistent naming convention, and the hard rule that UTM values are public — so they must never contain personal data or secrets.
