October 2026 Google Ads Update – Demand Gen Changes View-Through Conversion Reporting

Granular analysis and first look

Google Is Updating Demand Gen View-Through Conversion Reporting

Google Ads is changing the definition of a “view” used to attribute view-through conversions (VTCs) for Display ads running within Demand Gen campaigns.

The update applies specifically to Display inventory within Demand Gen and is intended to create more consistent VTC measurement across Demand Gen inventory.

Previously, Google relied on its Active View standard when determining whether an impression qualified for view-through attribution.

Under the new definition, Google will use a rendered ad impression. A view will now qualify once at least one pixel of the ad appears on screen for any amount of time.

What This Means for Advertisers

The threshold for receiving view-through conversion credit is becoming significantly less restrictive.

Because an impression no longer needs to satisfy the Active View standard, advertisers may begin seeing higher VTC totals from Demand Gen Display inventory even if actual campaign performance has not materially changed.

This is especially important when evaluating historical performance. A rise in view-through conversions after the change may partially reflect the new measurement methodology rather than an increase in incremental conversions generated by the campaign.

Advertisers who include VTCs in campaign reporting, optimization decisions or attribution analysis should keep the methodology change in mind when comparing performance before and after the transition.

Key Takeaways

• VTCs may increase without an equivalent improvement in actual campaign performance 
• The change only applies to Display ads within Demand Gen campaigns.
• Google is moving from an Active View-based definition to a rendered impression definition for VTC attribution.
• A view can qualify when just one pixel appears on screen for any amount of time.
• This could result in more reported view-through conversions.
• Historical VTC comparisons may become less apples-to-apples after the change.
• No campaign changes are required; Google will implement the update automatically.

What Advertisers Should Watch

While no action is required, advertisers should monitor Demand Gen reporting once the new definition takes effect.

If VTC volume increases while clicks, engaged visits and other conversion indicators remain relatively stable, the reporting methodology change may be contributing to the difference.

For advertisers using view-through conversions to evaluate Demand Gen’s broader influence, this also reinforces the importance of looking beyond attributed conversions alone and considering incrementality, assisted conversions and other measures of downstream business impact.

Google says the new definition will roll out automatically in the coming weeks.
