Google Demand Gen View-Through Conversions Just Changed

First-Party Data 101

Quick Answer: A view-through conversion is a purchase Google credits to an ad someone saw but didn't click. Google has changed how Demand Gen handles them twice in two months. In August, it made view-through optimization video-only, turned it on by default for new Demand Gen campaigns, and extended it to the Google Display Network. On October 5, it announced that for Display ads in Demand Gen, an impression qualifies for view-through credit once a single pixel appears on screen, instead of meeting Active View. Neither change touches your actual sales, but both can move what Google reports. Display view-through numbers will likely rise. Campaigns that were bidding on image view-throughs may report fewer conversions, because those no longer count in the main Conversions column. Before BFCM, note the date each change reached your account, segment Demand Gen conversions by ad event type, and check Google's numbers against your Shopify orders.

Key Takeaways

A view-through conversion is credit for an ad someone saw, not clicked. It says nothing about whether the ad caused the purchase.
For Display ads in Demand Gen, "seen" now means one pixel on screen for any duration. That's a much lower bar than Active View, so more impressions qualify for credit.
When view-through optimization is on, only view-throughs from video ads land in the main Conversions column, which feeds ROAS and bidding. Image view-throughs stay in reporting.
New Demand Gen campaigns optimize for view-through conversions by default. Existing campaigns keep their current settings.
Reported conversions can move up or down with no change in customers. Compare against Shopify orders, and annotate both change dates in every report.

Google has spent the last two months quietly changing what counts as a conversion in Demand Gen. None of it requires you to touch a setting, and most of it lands right as brands start building BFCM reports.

Here's the risk. Your Demand Gen campaigns start reporting more conversions. ROAS goes up. Someone moves budget toward the campaign that looks like it's winning. And nothing about your actual sales changed, because what changed was the rule for which ads get credit.

I'm not saying view-through conversions are useless. Video ads in particular can drive purchases people don't click to make. But a reporting change isn't a performance change, and the two are about to look identical in your dashboard.

What is a view-through conversion?

Google counts a view-through conversion when someone sees your ad, doesn't click or interact with it, and later converts on your site within your view-through window. If the same person also interacted with any of your other ads, Google gives the credit to that interaction instead.

For most campaign types, view-through conversions are reporting only. They show up in the "View-through conversions" and "All conversions" columns, not the main Conversions column. Demand Gen is one of the exceptions. When view-through optimization is on, eligible view-through conversions from video ads are included in the main Conversions column, so they feed into reported ROAS and into bidding.

One more detail worth knowing: Google can't report view-through conversions from browsers that block cross-site cookies, so the numbers you do see are a partial picture by design.

What changed in Demand Gen?

There are two separate changes, announced about two months apart.

1. View-through optimization changed (announced in August). Google said it would roll out three changes to view-through optimization in Demand Gen over the following months:

Video only for bidding. View-through conversions from image assets are still reported as secondary conversions in existing campaigns, but they no longer count for bidding or appear in the main Conversions column.
On by default for new campaigns. New Demand Gen campaigns have view-through optimization switched on, and you have to opt out manually. Existing campaigns keep their current settings.
Expanded to Display. View-through optimization extends beyond YouTube and the Discover feed to the Google Display Network. Video ads served on Display also move from cost-per-click to cost-per-thousand-impressions billing, whether or not you use view-through optimization.

2. The definition of a view changed (announced October 5). For Display ads in Demand Gen, Google is moving view-through attribution from Active View to a rendered impression. Google says the goal is consistency across Demand Gen inventory, since its view-through optimization already counted a view as one pixel on screen. Eligible campaigns move over automatically in the coming weeks, with no setting to change.

How big is the definition change?

	Active View (before)	Rendered impression (now, Demand Gen Display)
Standard display ad	At least 50% of the ad visible for at least one second	At least one pixel on screen, for any amount of time
Large display ad (242,500 pixels or more)	At least 30% visible for at least one second	At least one pixel on screen, for any amount of time
What it can prove	The ad had a reasonable chance to be seen	The ad loaded on the screen
Effect on view-through credit	Fewer impressions qualify	More impressions qualify, including brief, partial ones

Neither standard proves someone actually looked at your ad. But a sliver of an ad scrolling past for a fraction of a second can now qualify an impression for credit, where it wouldn't have before.

Why does this matter for Shopify brands?

Your reports will cross a measurement boundary. A Demand Gen campaign reporting more conversions after the switch is being judged by a different rule. Comparing October to September across that line tells you about the rule, not the campaign.

Some campaigns will look worse, not better. If you turned on view-through optimization earlier this year and ran image assets, those image view-throughs used to count in your main Conversions column. They don't anymore. Reported conversions and ROAS can drop on those campaigns even while sales hold steady.

Google's purchases will drift further from Shopify's. Shopify counts each order once. Google can now credit more of those same orders to an impression. Meta may be crediting some of them too, through its own view-through window. Every platform claiming an order doesn't create a new one, so the gap between ad platform totals and Shopify orders widens without any change in demand.

Budget follows the number. When view-through optimization is on, view-throughs from video ads land in the main Conversions column, which feeds reported ROAS and Google's bidding. Image view-throughs don't, so on image-heavy Display the one-pixel change mostly shows up in the View-through conversions column instead. Either way, during BFCM a campaign that looks better or worse because of a definition change can pull spend in the wrong direction.

New campaigns behave differently from old ones. Because view-through optimization is on by default for new Demand Gen campaigns only, two similar campaigns can now report on different rules. Check the setting on anything you launch for BFCM.

How should you read Demand Gen reports now?

Note the date. Find when the rendered impression change reached your account and mark it in every report and dashboard that includes Demand Gen. Don't compare conversion totals across it without a note.
Segment by ad event type. In Google Ads, add the Segments menu option for conversions by ad event type. View-through conversions from optimized campaigns show up as "Impression," separate from clicks and engaged views.
Separate Display from YouTube. Use the network segment to look at Google Display Network results on their own, since that's where the definition change applies.
Check the view-through column too. The "View-through conversions" column includes biddable and non-biddable view-throughs, while the main Conversions column only includes eligible ones when optimization is on.
Check your view-through window. A longer window credits more conversions to impressions. Make sure it hasn't changed between the periods you're comparing.
Check new campaign settings. For anything you launch for BFCM, decide deliberately whether view-through optimization should be on, rather than inheriting the default.
Reconcile against Shopify orders. Compare Google's reported purchases, click-based and view-through separately, with your actual Shopify orders for the same window. If view-through conversions are climbing and Shopify orders aren't, you're looking at a reporting change.

If your account has access to Conversion Lift, that's the better test of whether Demand Gen video is driving purchases. It compares people who saw your ads with a group held back from seeing them, which measures added sales, not credit.

Where Aimerce fits

Google decides how to credit a purchase. Aimerce makes sure the purchases it's crediting are your real Shopify orders. Aimerce sends Shopify purchases to Google and Meta server-side from Shopify's order data, so every platform is matched against the same set of orders, however each one chooses to assign credit.

That's also why Aimerce's Attribution page shows Google next to Meta and other channels, built from the same Shopify orders. When Google changes its own rules mid-quarter, you still have one set of orders to compare every channel against.

FAQ

What is a view-through conversion in Google Ads? A conversion Google credits to an ad someone saw but didn't click or interact with, when they convert later within your view-through window. If they interacted with another of your ads, that interaction gets the credit instead.

What changed with Demand Gen view-through conversions? For Display ads in Demand Gen, an impression now qualifies for view-through credit if at least one pixel appears on screen for any duration, instead of meeting Active View. Separately, view-through optimization became video-only for bidding, is on by default for new Demand Gen campaigns, and expanded to the Google Display Network.

Will my Demand Gen conversions go up? Some will, and some may go down. Display view-through numbers can rise because a lower bar means more impressions qualify. Campaigns that were bidding on image view-throughs can report fewer conversions, because those no longer count in the main Conversions column. Neither direction reflects a change in actual sales. Note the change dates and compare against Shopify orders.

Do view-through conversions count in the main Conversions column? For most campaign types, no, they're reporting only. In Demand Gen campaigns with view-through optimization on, eligible view-throughs from video ads are included in the main Conversions column and used for bidding. Image view-throughs stay in reporting only.

How do I see view-through conversions separately? Segment conversions by ad event type in Google Ads. View-through conversions from optimized campaigns appear as "Impression." You can also use the network segment to isolate Google Display Network results.

Should I turn off view-through optimization? Not automatically. It can help video campaigns that drive purchases without clicks. Decide per campaign, judge results against Shopify orders rather than Google's totals, and use Conversion Lift if it's available to you.
