View-Through Conversions (VTCs) are conversions that occur when a user sees your Google Ads display or video ad, does not click it, but later visits your website and completes a conversion action within a specified lookback window (default 1 day). They measure the indirect influence of ad impressions on user behavior.
Key Takeaways
- VTCs count conversions from users who saw but did not click your ad
- Default lookback window is 1 day (configurable up to 30 days)
- Only available for Display, Video, and Performance Max campaigns
- VTCs are reported separately from click-through conversions and are not included in the standard “Conversions” column by default
- They help measure upper-funnel campaign impact that click-based metrics miss
What Is a View-Through Conversion
View-Through Conversions capture the value of ad impressions that influence behavior without a direct click. A user sees a display banner or watches a portion of a video ad, does not click, but later navigates to your site through another channel (direct, organic, or a different ad) and converts.
| Conversion Type | User Path | Attribution |
|---|---|---|
| Click-Through | Sees ad, clicks, converts | Direct: click to conversion |
| View-Through | Sees ad, does NOT click, converts later | Indirect: impression to conversion |
The distinction matters because many users — especially on Display and YouTube — absorb ad messaging without clicking. VTCs attempt to quantify that influence.
How It Works
Google tracks view-through conversions using cookies and Google’s signed-in user data:
- User sees your ad — an impression is recorded
- User does NOT click — no click-through occurs
- User later visits your site — through any channel within the lookback window
- User converts — completes a tracked conversion action
- Google attributes a VTC — linking the impression to the conversion
Key rules for VTC attribution in the 2026 Google Ads system:
- Click always wins — if the user clicked any Google Ads ad before converting, the click gets full credit and no VTC is recorded
- Last impression wins — if multiple Display/Video ads were viewed, the most recent impression gets the VTC credit
- Lookback window — configurable per conversion action (1 to 30 days, default 1 day)
- Not in Conversions column — VTCs appear in a separate “View-through conv.” column and are not included in the default “Conversions” metric unless you modify your conversion settings
Practical Example
A furniture retailer runs a Display campaign alongside Search campaigns:
| Campaign | Spend | Click Conversions | VTCs | Combined | CPA (Click Only) | CPA (Combined) |
|---|---|---|---|---|---|---|
| Search - Branded | $3,000 | 120 | 0 | 120 | $25.00 | $25.00 |
| Search - Non-Brand | $5,000 | 50 | 0 | 50 | $100.00 | $100.00 |
| Display - Prospecting | $4,000 | 8 | 45 | 53 | $500.00 | $75.47 |
Without VTCs, the Display campaign looks disastrous at $500 CPA on click-through conversions alone. With VTCs, the adjusted CPA drops to $75.47 — competitive with non-branded Search.
The question is: how much credit should VTCs receive? A conservative approach:
- Weight VTCs at 50%: adjusted conversions = 8 + (45 x 0.5) = 30.5
- Adjusted CPA: $4,000 / 30.5 = $131.15
Even at 50% weighting, Display prospecting delivers meaningful value. Without VTC data, the retailer might cut the Display budget entirely and lose the awareness pipeline feeding branded and direct conversions.
Why It Matters
View-through conversions are essential for evaluating upper-funnel campaigns that click-based metrics systematically undervalue:
- Display and Video justification — Display campaigns and Video campaigns often have CTRs below 1%. Without VTCs, their contribution to conversions is massively understated.
- Full-funnel measurement — VTCs reveal the relationship between awareness impressions and downstream conversions, connecting top-of-funnel investment to bottom-of-funnel results.
- Budget allocation — ignoring VTCs leads to over-investing in lower-funnel channels (Search, branded) at the expense of the awareness campaigns that feed them.
- Incrementality testing — compare VTC rates across audiences and placements to estimate which impressions are genuinely incremental versus coincidental.
Handle VTCs with appropriate skepticism. A 1-day window is more credible than a 30-day window. Weight VTCs at less than 100% of a click-through conversion. And always watch for correlation without causation — some VTCs would have converted regardless of seeing your ad. Use geo-based or holdout experiments to measure true incrementality when budgets are significant.
