View-Through Conversion, explained properly.
Quick answer
A view-through conversion (VTC) happens when someone sees your display, video, or YouTube ad without clicking it, but then converts on your site within a defined window (typically 30 days). VTCs help measure the awareness and brand-building impact of upper-funnel campaigns that would not otherwise show up in last-click attribution.
How VTCs work in Google Ads
Google records a VTC when: 1. A user's browser loads your ad (counts as a viewable impression). 2. The user does NOT click the ad. 3. Within the view-through window (default 30 days), the user reaches a conversion page on your site through any other path. VTCs appear in Google Ads reports under a separate column from primary conversions. They are not counted in Smart Bidding optimisation by default.
When VTCs matter
- **Display campaigns:** most display traffic does not click but does see ads, then converts later via search or direct. - **YouTube campaigns:** especially for awareness goals where view-through impact matters. - **B2B with long sales cycles:** where users need multiple touchpoints before converting. - **Brand campaigns:** where the goal is awareness rather than direct response.

Understanding view-through conversions is essential for accounts running display, YouTube, or other awareness-focused campaigns. We help clients calibrate VTC reporting that is honest rather than inflated. Ready to apply this to your own account?

View-Through Conversion: common questions.
Are view-through conversions accurate?
Approximately. VTCs rely on cookies and device IDs, which face increasing limits from privacy regulations and browser changes. Modern VTC reporting includes a degree of statistical modelling. Treat the numbers as directional rather than precise.
Should I include VTCs in ROAS calculations?
Cautiously. Including 100% of VTCs at full conversion value typically overstates campaign performance. A conservative approach is to count VTCs at 25 to 50 per cent of click conversion value, or report two ROAS figures: with and without view-throughs.
What is the default view-through window?
30 days for most conversion types in Google Ads. Some advertisers shorten it to 7 days for display-heavy accounts to filter incidental impressions. Some lengthen it to 60 to 90 days for B2B with long buying cycles.
Do view-through conversions feed Smart Bidding?
By default, no. Smart Bidding optimises against click conversions only. You can include VTCs in Smart Bidding optimisation, but doing so changes how the algorithm values upper-funnel impressions. Test cautiously.
What clients say about working with us.
“I've had the pleasure of working with Chris on several SEO projects for my websites in the health field. He was definitely been able to demystify things so that I felt able to make decisions with him and feel confident they were the right ones. For a non-techie, that is worth gold! I look forward to working with Chris again and warmly recommend him to anyone who - like me - is unsure about all things SEO.”
