Manual ad content dimension
The manual ad content dimension exposes the utm_content campaign parameter — conventionally used to distinguish two links to the same destination, such as A/B creative variants or header-versus-footer placements. GA4 reports it as 'Manual ad content' with scope-aware variants. It is free text, so its meaning is entirely a function of your tagging discipline, and it is distinct from auto-tagged Google Ads creative data.
What this means
Manual ad content is GA4's name for the utm_content parameter. Its conventional job is to tell apart multiple links that point to the same place — for example two button creatives in one email, or the same link in a header and a footer.
Like other manual parameters it is free text, and GA4 exposes it in scope-aware forms (manual ad content, session and first-user variants).
Manual vs auto-tagged creative
With Google Ads auto-tagging, creative-level data arrives through the gclid linkage and appears in Ads creative dimensions, not in utm_content. Manual ad content reflects only the variant labels you tagged by hand. Reading both as one creative report double-counts. Standardise a naming scheme so variant comparisons stay legible.
- Reads the utm_content parameter verbatim
- Conventionally distinguishes A/B link variants
- Separate from auto-tagged Google Ads creative
How it appears in analytics and logs
A manual ad content value is exactly the utm_content string you set. Empty or (not set) means the link had no utm_content, not that there was a single creative.
Diagnostic use case
Use manual ad content to separate clicks from competing link variants — A/B copy, placement, or button — that share a campaign and destination.
What WebmasterID can help detect
WebmasterID reads utm_content first-party from the landing URL, so creative/variant labels stay tied to the session without third-party tracking.
Common mistakes
- Using inconsistent utm_content labels across a test.
- Expecting auto-tagged creatives under manual ad content.
- Placing personal data into utm_content.
Privacy and accuracy notes
Manual ad content is self-declared metadata, not identity. Keep personal data out of utm_content, which is logged in URLs across the stack.

- Ad content dimension: distinguishing creative variants
Ad content is the dimension fed by the utm_content parameter. Its job is to differentiate links or ad creatives that share the same source, medium, and campaign — for example two buttons in one email or two banner variants in one campaign. It does not affect channel attribution; it is purely a label for distinguishing creative or placement, which makes it ideal for A/B and link-position analysis.
- Manual term dimension
The manual term dimension exposes the value you place in the utm_term campaign parameter — conventionally the paid keyword for a manually tagged ad. GA4 reports it as 'Manual term' (or session/first-user variants). Because it is whatever you typed, it is only as accurate as your tagging; it is not the auto-tagged keyword Google Ads supplies via the gclid linkage, and the two should not be conflated.
- Ad creative dimension
An ad creative is the specific image, text, or video asset shown in an ad. Analytics tools surface a creative dimension so you can compare which asset drove a click; GA4 populates it from linked Google Ads, while other channels rely on utm_content. This page covers derivation and the volatility of creative identifiers.
