On June 25, 2026, Google shipped its June Demand Gen Drop, and it changes what a competent Q3 YouTube plan looks like. Three things landed at once: Gemini creative recommendations inside the Demand Gen asset picker, expanded auto-resize that transforms one video across 16:9, 1:1, and 9:16, and Web to App Acquisition Measurement (WAM) that finally attributes app installs back to Demand Gen web campaigns. If your Q3 asset brief was written before June 25, it's already stale.
Key Takeaways
- Google's June 25 Demand Gen Drop shipped three things: Gemini creative recommendations at asset selection ("coming soon"), auto-resize between 9:16, 1:1, and 16:9 (rolling out), and Web to App Acquisition Measurement (WAM), which is live now.
- Auto-resize is enabled by default at the ad level in Demand Gen. Per Google Ads Help, you can turn it off, but the default is on, so any video you upload will be transformed unless you opt out.
- WAM has one hard eligibility trap: it doesn't work when a web campaign sends users directly to an app store. If your Demand Gen landing page bounces to the Play Store or App Store, WAM cannot attribute the install.
- The practical Q3 move is a three-part refresh: rewrite the asset brief around one vertical hero cut, gate every video through the resize preview before launch, and re-check every Demand Gen campaign that touches app installs against WAM's eligibility rules.
What Google Actually Shipped in the June 2026 Demand Gen Drop
Google announced three Demand Gen updates in one post on June 25, 2026, and the reason to care is that all three change the workflow, not just the reporting. Demand Gen is Google's visual-discovery campaign type, serving on YouTube (in-stream, in-feed, Shorts), Discover, and Gmail. The June Drop targets the three friction points buyers actually complain about: creative iteration speed, aspect-ratio production overhead, and app-install attribution.
The official Google announcement frames the release as "boosting Demand Gen campaign performance" and cites research from Measured that 72% of incremental conversions on YouTube come from new customers. According to Google (2026), the Drop is designed to help Demand Gen capture more of those new-customer conversions across all screens by cutting creative friction and closing the app-attribution loop.
The three shipped features are:
- Gemini creative recommendations inside the Demand Gen asset selection workflow (announced as "coming soon").
- Expanded video auto-resize covering vertical-to-square, vertical-to-landscape, and square-to-landscape transformations, per Google Ads Help 13652431.
- Web to App Acquisition Measurement (WAM), which measures app installs generated by web-focused Demand Gen campaigns, per Google Ads Help 16440462. WAM is live in the June 25 release. Gemini recommendations and the expanded resizing are labelled "soon."
Three named PPC editors covered the Drop the day it landed. Anu Adegbola, Paid Media Editor at Search Engine Land, framed the Drop as Google giving Demand Gen "new AI creative and reporting tools" on June 25. Andrew Hutchinson at Social Media Today wrote it up the same day as Google adding "AI guidance to Demand Gen campaigns". Nelson Oboh at The Keyword led with the Gemini creative angle a day later. None of them wrote the media-plan rewrite, which is what this post is for.
What Are Gemini Creative Recommendations in Demand Gen?
Gemini creative recommendations are automated suggestions that surface inside the Demand Gen asset picker when you're selecting image and video creative, aimed at helping you pick or produce a better asset for YouTube before the campaign goes live. Per Google's June 25 announcement, the recommendations run at the point of asset selection, not after the fact.
Two things matter about the framing. First, Google said "coming soon," not "live." Nothing in the June 25 post named a specific rollout date, and there is no separate Help article for the Gemini layer as of publish. That means Q3 planners should expect this to appear in the interface over the next few weeks, not gate a launch on it. Second, this is a recommendation surface, not an auto-generation surface. Google is not (in this Drop) generating a new video for you. It's grading and suggesting improvements on the assets you upload.
This lands on top of Google's broader Gemini push across the Ads stack, which through 2026 has moved from novelty into the default creative workflow. According to Anu Adegbola at Search Engine Land (2026), the intent is to reduce creative friction before launch by grading assets in the picker, which means the buyers who benefit are the ones who ship more asset variants, not the ones who ship one polished hero and freeze it.
The tactical implication: your asset brief should now produce 3 to 5 A/B-ready variants per creative concept, because Gemini's recommendations are only useful when there's a set to grade against, not a single locked hero.
How Does Demand Gen Auto-Resize Work in 2026?
Demand Gen auto-resize takes one video you upload and generates additional aspect-ratio versions automatically, so a single creative can serve across YouTube's in-stream (16:9), in-feed and TrueView (1:1), and Shorts (9:16) placements without a manual re-cut per format. Per Google Ads Help article 13652431, the AI-generated orientation versions run automatically after a quality review, and the extra versions are added to the ad if they pass.
The June Drop expanded the transformation matrix. Previously the ad-level video enhancement pattern in Demand Gen was primarily landscape-to-vertical. As of June 25, 2026, Demand Gen supports vertical-to-square, vertical-to-landscape, and square-to-landscape as well. In practical terms, a vertical Shorts-style asset can now be transformed up to a 16:9 in-stream unit, not just squeezed the other direction.
Per Google Ads Help 13652431, the auto-resize control lives at the ad level and is enabled by default in Demand Gen. Buyers can turn it off, but only ad-by-ad. That's the setting to check before Q3 launch, because a locked-brand YouTube spot with a strict aspect-ratio requirement will otherwise be transformed and re-served in ratios the brand team never approved.
The output is a single hero brief that produces one master vertical cut, and Google's system fans out the other ratios automatically. That's a big change for how in-house teams and creative agencies scope video production. According to Andrew Hutchinson at Social Media Today (2026), the expanded resizing is intended to reduce the "manual re-editing" burden for creative teams. In practice, it means the pre-June asset brief that called for a 16:9 hero and a separate 9:16 Shorts cut can collapse to one vertical hero plus a resize review gate before launch.
What Is Web to App Acquisition Measurement (WAM)?
Web to App Acquisition Measurement (WAM) is the new Google Ads attribution feature that measures when a user clicks a web-focused Demand Gen campaign and then installs the advertiser's app, closing a long-standing attribution gap between web media and app installs. Per Google Ads Help article 16440462, WAM supports Demand Gen among other campaign types and both Android and iOS.
WAM has two eligibility requirements that Q3 planners have to check before assuming the report will populate:
- Imported first-open events. The advertiser must import first-open events for the relevant apps into Google Ads. Without those events, WAM has no signal to attribute against.
- No direct app-store handoff. Per Google Ads Help 16440462, WAM is "unavailable when web campaigns send users directly to an app store." If your Demand Gen landing page is a smart banner or link that bounces the user straight to the Play Store or App Store listing, WAM will not attribute the install. The traffic has to actually land on the web page.
That second rule is the trap. Plenty of app-first advertisers set Demand Gen landing pages to a deep link that hands the user to their store listing on tap. That's exactly the pattern WAM will not measure. If app installs matter to how a Q3 Demand Gen budget is judged, the landing page has to land, not redirect.
According to Google (2026), WAM is designed to give a "more complete view" of Demand Gen performance by attributing installs the pre-June reporting missed entirely. In practice, that means Q3 ROAS on Demand Gen for hybrid web-plus-app advertisers will look higher than Q2 did, purely because more of the conversion is now being counted. Don't confuse an attribution catch-up with a real lift.
The Q3 Demand Gen Refresh Checklist
Here is the three-part refresh I'm running against every Demand Gen account I touch this quarter. It's ordered by impact. The asset brief is the biggest change. The resize gate is the fastest. The WAM check is the one that most people will forget.
1. Rewrite the Asset Brief Around a Vertical Hero
The old brief called for two locked cuts: a 16:9 hero for in-stream and a 9:16 for Shorts. The new brief calls for one vertical hero at 9:16 that is production-designed to auto-resize up to 1:1 and 16:9 cleanly. That means keeping the primary subject inside the safe crop zone for both square and landscape framings, avoiding text at the vertical extremes, and delivering 3 to 5 short variants of the hero for Gemini recommendations to grade against.
If your creative agency still bills per aspect ratio produced, this conversation happens now, not in October. The transformation math is 3-to-1 in a Demand Gen buyer's favor.
2. Gate Every Video Through the Resize Preview Before Launch
Because Demand Gen auto-resize is on by default at the ad level, the failure mode is a transformed 16:9 or 1:1 that the brand team never saw. Before every Q3 launch, preview each generated aspect ratio in the ad, and decide per ad whether to keep the default on. For any brand-sensitive spot (talent likeness, regulated category, licensed music with framing constraints), turn the transformation off ad-by-ad and produce the extra ratios manually.
This is a five-minute check per campaign that prevents an off-brand version from running in a placement the brand team never approved.
3. Re-Check Every Web-Plus-App Demand Gen Campaign Against WAM Eligibility
For every existing Demand Gen campaign that could reasonably drive an app install, run through the WAM eligibility rules from Google Ads Help 16440462:
- Is the app's first-open event imported into Google Ads?
- Does the campaign's landing page actually land, or does it deep-link into the Play Store or App Store?
- Is Demand Gen turned on as a supported campaign type in the account's conversion setup?
If the answer to any of those is no, either fix the setup or explicitly exclude the campaign from your app-install ROAS math for Q3. Don't let a WAM-eligible-looking campaign that's actually ineligible quietly show a lower "true" ROAS than it should.
Where Demand Gen Now Sits Against Performance Max
Demand Gen and Performance Max are Google's two AI-driven campaign types, and the June Drop widens the gap between them in a way that matters for Q3 planning. Performance Max is the everything-inventory campaign optimized for a single conversion goal, and it now covers Search, Shopping, Display, YouTube, Discover, Gmail, and Maps. Demand Gen is narrower on purpose: visual-first surfaces (YouTube, Discover, Gmail) optimized for demand creation, not last-click harvesting.
With Gemini in the asset picker and auto-resize handling aspect ratios, Demand Gen is now the more sensible choice for buyers who want to keep creative control on the video side while still using Google's AI on the media side. Performance Max still owns the branded-search-and-shopping harvesting job. Demand Gen owns the top-of-funnel video and visual-discovery job.
For most Q3 budgets I plan, the split I'd argue for is Performance Max on branded and high-intent commercial terms plus product feed, Demand Gen on the new-customer YouTube and Discover surfaces, with the creative and measurement upgrades from the June Drop actually used, not just noted.
Frequently Asked Questions
When did Google announce the June 2026 Demand Gen Drop?
Google announced the Drop on June 25, 2026, on the official Google Ads blog under the title "Boost Demand Gen campaign performance with June's Drop." Three features shipped or were announced together: Gemini creative recommendations, expanded video auto-resize, and Web to App Acquisition Measurement.
Is Gemini creative for Demand Gen live now, or coming soon?
Per Google's own announcement, Gemini creative recommendations are labelled "coming soon" as of June 25, 2026. Google did not name a specific rollout date. Expanded video auto-resize was also framed as "coming soon." WAM is the only one of the three that Google described as available immediately.
Does Demand Gen auto-resize really cover 16:9, 1:1, and 9:16?
Yes. Per Google Ads Help article 13652431, the video enhancement feature generates AI-based orientation versions in 16:9, 1:1, and 9:16, and after the June 25, 2026 Drop, the supported transformation matrix includes vertical-to-square, vertical-to-landscape, and square-to-landscape. The control is at the ad level in Demand Gen and defaults to on.
What does WAM require to actually work?
Two things. First, first-open events for the advertiser's app have to be imported into Google Ads. Second, the Demand Gen landing page has to land on the web, not redirect the user directly into the Play Store or App Store. Per Google Ads Help 16440462, WAM is unavailable when a web campaign sends users straight to an app store listing.
Should I move budget from Performance Max to Demand Gen because of this Drop?
Not automatically. Performance Max still owns branded-search harvesting and product-feed shopping. What the June Drop does change is the case for Demand Gen on the top-of-funnel YouTube and Discover surfaces, because the creative production cost per campaign just dropped and the app-install attribution just got closed. If you were under-investing in Demand Gen because of production overhead or attribution gaps, that constraint eased on June 25.
Where do I read the source documents?
Start with the official Google announcement of the June 2026 Demand Gen Drop. Then read Google Ads Help 13652431 on video enhancements for the exact aspect-ratio behavior, and Google Ads Help 16440462 on Web to App Acquisition Measurement for the eligibility rules.
