Quick answer: A view-through conversion (VTC) is a conversion credited to an ad that someone saw but did not click or interact with. It is counted only if the person converts inside the view-through window, which is 1 day by default on Google Ads and Meta and 7 days on LinkedIn.
A view-through conversion is the platform’s way of saying: “this person saw your ad, did nothing, and later bought anyway.” The ad platform records the impression, and if that same person converts within the window, the sale is credited to the ad. No click ever happened. The credit comes purely from the impression being served.
View-through conversions are mostly used to measure display, video and social campaigns, where people often watch or scroll past an ad without clicking. On Google Ads, the conversion is credited to the last viewable impression. For Display Network ads, “viewable” means at least 50% of the ad was on screen for at least one second (Google Ads Help).
Why view-through conversions matter
View-through conversions matter because they change how upper-funnel campaigns look. A YouTube or Display campaign with very few clicks can still show healthy conversion numbers once views are counted. That is useful, since people do buy after seeing an ad without clicking it. It is also risky, since an impression proves the ad was served, not that it caused the sale.
Take someone who saw your banner on a news site, ignored it, and bought through a Google search the next morning. They would probably have bought anyway, but the view-through window still gives the banner credit. This is why VTC numbers are always more generous than click numbers, and why they are the first place to look when platform-reported results do not match your actual revenue.
There are also built-in limits on what VTC can show you:
- Google Ads keeps VTC out of your main “Conversions” column. It appears only in the “View-through conversions” and “All conversions” columns, so it does not feed bidding by default (Google Ads Help).
- Google excludes people who also interacted with another of your ads. If the user clicked any of your ads, the sale is treated as a click-based conversion instead.
- Browsers that block cross-site cookies cannot report VTC. Safari and Firefox users are largely invisible here, so VTC systematically under-counts some audiences while over-crediting others.
- Windows are short. Google’s default view-through window is 1 day, and Meta’s longest available view window is now 1 day (Google Ads Help).
Platforms differ on all of this, so the same customer journey can show up as a VTC on one platform and not at all on another. For the underlying window settings, see our attribution window glossary entry.
Click-through vs view-through vs engage-through conversions
| Attribute | Click-through conversion | View-through conversion | Engage-through conversion (Meta) |
|---|---|---|---|
| What triggers it | User clicks the ad | Ad is seen, no interaction | Like, share, save or comment, but no link click |
| Google Ads default window | 30 days | 1 day | Not offered |
| Meta default window | 7 days | 1 day | 1 day |
| LinkedIn default window | 30 days | 7 days | Not offered |
| Strength of signal | Strongest, the user acted | Weakest, exposure only | Middle, real interaction but no click |
| Counted in Google “Conversions” column? | Yes | No, shown separately | Not applicable |
| Best used for | Performance reporting and bidding | Awareness and video, reported separately | Meta social, checked before trusting |
Never merge click-through and view-through conversions into one headline number. Report them side by side, so the client can see how much of the result rests on clicks and how much on impressions.
How to use view-through conversions properly
- Find the VTC columns. In Google Ads, add “View-through conversions” and “All conversions” to your campaign view. In Meta Ads Manager, break results down by attribution setting so click and view are shown separately.
- Report VTC separately from click conversions. Use click-based numbers for ROAS, CPA and budget decisions. Show VTC as a supporting number for awareness campaigns.
- Keep the view window short. One day is enough for most businesses. A long view window mainly adds sales that would have happened anyway.
- Look at overlap. If a campaign’s VTC is high but the same customers also see your search and retargeting ads, you are likely counting one sale across several channels.
- Test for real impact. Run a conversion lift test or use a holdout group to see how many sales the ad actually caused, rather than how many it was present for.
- Check against revenue. Compare platform totals with your actual sales and blended ROAS. If the platforms claim more than you banked, VTC is usually part of the gap.
Here is what this looks like in practice. Take an illustrative Mumbai D2C brand spending ₹1,50,000 a month on YouTube and Display, with an average order value of ₹4,000:
- Click-through only: 60 purchases, ₹2,40,000 revenue, 1.6x ROAS
- Click + view-through: 150 purchases, ₹6,00,000 revenue, 4.0x ROAS
At a 40% gross margin, break-even ROAS is 1 / 0.40 = 2.5x. On clicks alone, the campaign loses money. With VTC added, it looks very profitable. The truth is probably somewhere in between, and only a lift test can tell you where. See our ROAS glossary entry for the break-even maths.
Common mistakes
- Adding VTC to click conversions and calling it ROAS. This is the most common way display and video campaigns end up looking better than they are.
- Treating a view as proof of influence. An impression means the ad was shown, not that the person noticed it. On Google video campaigns, an impression is also different from a “view”, which needs about 30 seconds of watching or a click.
- Optimising bidding on VTC. Pushing the algorithm toward people who merely see ads can steer spend to audiences who were already about to buy.
- Ignoring overlap between platforms. Meta, Google and LinkedIn each claim the same sale if the person saw an ad on all three. Added together, the claimed conversions will exceed real orders.
- Dismissing VTC completely. Some awareness spend does lead to later purchases. The right move is to measure it with a holdout test, not to delete it from the report.
- Changing the view window and comparing to old data. Window changes apply going forward only, so trends that cross the change date compare two different measurement rules.
Frequently asked questions
What is a view-through conversion?
A view-through conversion is a conversion credited to an ad that the customer saw but did not click. The platform records the impression, and if the same person converts inside the view-through window, the ad gets credit. It is most common in display, video and social campaigns.
What is the default view-through window on Google Ads?
Google Ads uses a 1-day view-through window by default, and you can change it per conversion action when you create or edit it. A longer window usually produces more view-through conversions, but it also adds more sales that the ad did not cause.
Does Meta still offer a 7-day view-through window?
No. Since January 2026, Meta’s longest view-through window is 1 day, and the 7-day and 28-day view options are no longer available. Meta’s default for website conversions is 7-day click, 1-day engage-through and 1-day view.
Are view-through conversions included in Google Ads “Conversions”?
No. View-through conversions appear only in the “View-through conversions” and “All conversions” columns, not in the main “Conversions” column used for bidding. This keeps impression-only credit separate from click-based results.
Are view-through conversions reliable?
They show correlation, not cause. A view-through conversion proves an ad was served before a sale, not that the ad drove it. Use them as a directional signal for awareness campaigns, and confirm real impact with a lift test or holdout group before moving budget.
How Uginix helps
Uginix reports click-through and view-through conversions in separate columns, then compares both against your actual revenue so you can see how much of the platform-reported result is real. Our analytics and attribution work covers conversion tracking, GA4 setup, lift tests and cross-platform reconciliation. If your Google, Meta and LinkedIn numbers add up to more than your sales, our free growth audit is built to find out why.
