A conversion that happens after a user sees a display or video ad but does not click it, and then converts within a set attribution window.
Digital marketers reading about campaign performance and advertising metrics.
01What it is and how it works
View-through conversion tracking relies on cookies or device IDs to link an ad impression to a future conversion event. When a user is served a display or video ad that is viewable (per the Media Rating Council definition, at least 50% of pixels visible for one second for display, two seconds for video), the ad platform records the impression. If that user later completes a conversion — such as a purchase, sign-up, or lead — within a configurable time window (commonly 1 to 30 days) without having clicked the ad, the platform attributes that conversion as view-through. The attribution is typically last-click or data-driven, but the key difference is that no click occurred. The mechanism requires the user to have been exposed to the ad and then to convert on the same device or within the same browser environment, unless cross-device tracking is enabled.
Someone sees your ad, doesn't click, but later buys or signs up. That sale is counted as a view-through conversion if it happens within the time window you set.
02What to do about it
To use view-through conversions effectively, start by setting an appropriate attribution window in your ad platform. For brand awareness campaigns, a 7- to 14-day window is common; for direct response, a shorter window (1–3 days) reduces over-attribution. Enable viewability measurement and only count impressions that meet the MRC standard. Combine VTC data with click-through conversion data to get a fuller picture of campaign performance. Adjust bidding strategies: if you use target CPA or ROAS, decide whether to include view-through conversions in the model. Many platforms allow you to exclude VTCs from automated bidding to avoid inflating conversion counts. Finally, segment reports by conversion type (click-through vs. view-through) to compare the relative impact of each.
03How it is measured or noticed
In Google Ads, view-through conversions appear in the 'Conversions' column when you add the 'View-through conversions' metric. The platform shows the number of conversions attributed to impressions without clicks. You can also view the 'View-through conversion rate' and 'View-through conversion value'. Similar metrics exist in Meta Ads Manager under 'View content' or 'Landing page view' attribution settings. To notice a view-through conversion, look at the conversion path report: it will show an impression event followed by a conversion event with no click in between. Data-driven attribution models can also assign partial credit to view-through impressions. The key diagnostic is comparing the ratio of view-through to click-through conversions: a very high ratio may indicate a too-long window or low viewability thresholds.
04Common mistakes
- Setting an attribution window that is too long, which credits ads for conversions that would have happened anyway.
- Counting view-through conversions without verifying that the impression was actually viewable (e.g., below the fold, too short).
- Including view-through conversions in automated bidding without segmenting, causing the algorithm to overvalue low-engagement impressions.
- Ignoring the fact that view-through conversions often double-count users who also clicked another ad in the same campaign.
- Using view-through conversions as a primary KPI for direct-response campaigns where click-through conversions are more actionable.
- Failing to exclude view-through conversions from reports when comparing performance across channels that do not support VTC.
05Limits
View-through conversions are not applicable to search ads because search ads require a click to visit the landing page. They are also less reliable for upper-funnel campaigns where the conversion event is far in the future, as attribution windows become arbitrary. VTCs are often confused with click-through conversions, but the two measure fundamentally different user behaviors. Another common confusion is with 'view-through attribution' in multi-touch models, where view-through is just one touchpoint among many. The main limit is that VTCs rely on cookies and device IDs, which are increasingly restricted by privacy regulations and browser changes (e.g., third-party cookie deprecation). Without cross-device tracking, view-through conversions are only counted on the same device, missing cross-device influence.
06Worked example
A user browsing a news site sees a display ad for a new running shoe. They do not click the ad. Two days later, they search for the brand name on Google, click a paid search ad, and buy the shoes. In Google Ads, if the view-through conversion window is set to 7 days, this purchase is attributed as a view-through conversion from the display ad, because the user was exposed to the display impression and converted without clicking that specific ad. The search ad click is also recorded, but the view-through conversion gives credit to the display impression for influencing the purchase.
Frequently asked questions
How is a view-through conversion different from a click-through conversion?
A view-through conversion occurs when a user sees an ad but does not click it, then converts later within an attribution window. A click-through conversion requires a direct click on the ad. The key difference is that VTC measures brand impact from viewable impressions, while click-through tracks direct response.
Should I use view-through conversions for my campaign?
It depends on your goal. If your campaign aims for brand awareness and upper-funnel impact, view-through conversions are valuable. For direct response campaigns focused on immediate clicks, click-through conversions are more relevant. Consider your attribution model and whether viewable impressions drive conversions in your industry.
How do I set up view-through conversion tracking in Google Ads?
In Google Ads, you enable view-through conversions by adding the 'View-through conversions' column to your reports. You also set an attribution window (e.g., 1–30 days) in your conversion tracking settings. The platform uses cookies or device IDs to link impressions to future conversions automatically.
Are view-through conversions reliable for measuring ad effectiveness?
View-through conversions have limitations. They rely on cookies and device IDs, which can be affected by privacy changes and cross-device gaps. They also may overcount conversions if the attribution window is too long. Use them alongside other metrics and consider viewability thresholds for better reliability.
What happens if my attribution window for view-through conversions is too long?
A long attribution window can inflate conversion counts by attributing conversions that would have happened anyway without the ad impression. This leads to overestimating campaign performance. Start with a shorter window (e.g., 1 day) and test longer windows only if supported by data.
How long does it take for a view-through conversion to be recorded?
View-through conversions are recorded when the user converts within the set attribution window after seeing the ad. The exact timing depends on the user's behavior; it could be minutes or days. Check your ad platform's reporting for real-time or delayed updates, typically within 24 hours.

spoken, not typedThe same term in the words somebody uses speaking to an assistant rather than typing into a box — written from the situation, which is why each one carries the situation it came from.
Those are view-through conversions. They happen when someone sees your display or video ad, doesn't click, but later visits your site and converts. They show the brand impact of your impressions.
You should use view-through conversions. They measure conversions from people who saw your ad but didn't click, which demonstrates brand influence beyond direct response. Add the view-through conversion metric to your report to show that.
It depends on your goal. For direct response, track clicks. For brand awareness, track view-through conversions. If you're unsure, run both and compare the data to see what drives actual conversions.
