Demand Gen

Google's AI-powered visual advertising campaign type that serves ads across YouTube (in-stream, in-feed, Shorts, Home feed), Google Discover, Gmail (Social and Promotions tabs), Google Maps (promoted pins, beta as of 2026), and the Google Display Network (integrated from June 2026). It is the successor to Discovery Ads and Video Action Campaigns, and functions as Google's answer to Meta Advantage+ and TikTok for Business for mid-to-upper-funnel ecommerce advertising.

Origin and lineage

Demand Gen launched at Google Marketing Live 2023. It replaced Discovery Ads in March 2024. Video Action Campaigns (VAC) were absorbed into Demand Gen in July 2025, making Demand Gen the single container for all visual, engagement-driven Google advertising. (Source: Registry — Demand Gen 2026-07-11)

According to Store Growers (Dennis Moons, updated 2026-02-27), the primary driver of adoption was Google's forced sunset of Video Action Campaigns — advertisers had no alternative for conversion-optimised video on YouTube. Store Growers states: "This is the real reason Demand Gen adoption exploded. Not because the product was so compelling on its own merits. Because Google eliminated the alternative." (Source: Web — Demand Gen 2026-07-11)

Placement inventory

Demand Gen ads serve across (as-of 2026-07-11):

YouTube — in-feed, in-stream, Shorts (9:16 vertical), Home feed
Google Discover — native feed on Android and Google app
Gmail — Social and Promotions tabs
Google Maps — promoted pins (beta)
Google Display Network (GDN) — migrated into Demand Gen starting June 2026

Google states the network collectively reaches over 3 billion monthly users (Source: Registry — Demand Gen 2026-07-11, groas.com 2026-02-14).

As of March 2025, Demand Gen supports channel-level controls — advertisers can select which surfaces to activate (YouTube, Discover, Gmail, GDN individually), with no equivalent placement-level control available in Performance Max (PMax). (Source: Web — Demand Gen 2026-07-11)

Funnel position

Google (Feb/Apr 2026 Demand Gen Drop) positions Demand Gen as a conversion-driving channel, citing 40%+ more conversions for best-practice adopters and framing tROAS bidding as making it performance-capable. Source: Registry — Demand Gen 2026-07-11, blog.google 2026-02-24. Store Growers (2026-02-27) argues that no bidding strategy change alters the fundamental nature of the inventory: "You're interrupting people, not answering their questions." Demand Gen remains a top-of-funnel and mid-funnel channel regardless of tROAS repositioning. Source: Practitioner — Demand Gen 2026-07-11

The practitioner consensus (Store Growers, Brandcamp Digital, Cypress North, AdVenture Media — all 2025–2026) characterises Demand Gen as a mid-to-upper-funnel tool that feeds the purchase journey rather than closing it. Performance Max (PMax) is the bottom-of-funnel complement. Search Engine Land (2026-01-22) argues the two should run together in a full-funnel architecture. (Source: Web — Demand Gen 2026-07-11)

Ecommerce benchmarks (2026)

The benchmarks below are practitioner estimates from Store Growers (2026-02-27) based on multiple client accounts, not a statistically controlled study. Google's headline figures (see contradictions) use undisclosed baselines.

Realistic 2026 ecommerce Demand Gen benchmark ranges per Store Growers (as-of 2026-02-27):

Metric	Range	Notes
CTR	0.5–2%	Higher on YouTube in-feed; lower on Gmail and Discover
CPC	$0.30–$1.50	Luxury/competitive verticals push $2–$3
Conversion Rate	0.5–2%	For product feed campaigns actively pushing conversions
ROAS	2–5x	After learning period; expect 1.5–2x in weeks 1–2
CPA	$15–$60	Wide range reflects product price and margin variance
View Rate	15–35%	Below 15% = creative not holding attention

Placement-level CPC ranges (as-of 2026-02-27):

Discover: $0.20–$0.80 (high inventory, casual browse intent)
Gmail: higher CPC, low conversion yield ("hit or miss" per Store Growers)
YouTube: $0.50–$2+ (highest engagement and conversion quality)

Google's official published benchmarks: "26% more conversions per dollar spent" and "58% higher ROAS than Video Action Campaigns" — cited in multiple 2026 Demand Gen Drops. Source: Registry — Demand Gen 2026-07-11 Store Growers (2026-02-27): Calls both figures "marketing, not benchmarks."

2026 product updates (chronological)

January 2026 Demand Gen Drop

Shoppable Connected TV (CTV) reached general availability, enabling viewers to browse and purchase products on the big screen; Google internal experiment data shows DG campaigns including TV screens drive an average 7% additional conversions at the same ROI (as-of 2026-01, Source: [[Registry — Demand Gen 2026-07-11]])

Travel Feeds — connects Hotel Center feed data to dynamic video ads (as-of 2026-01, Source: [[Registry — Demand Gen 2026-07-11]])

February 2026 Demand Gen Drop

Google published four official Demand Gen best-practice pillars: (1) Audiences — use optimised targeting and Lookalikes; (2) Bid & Budget — use tCPA or tROAS with Performance Planner; (3) Creative — achieve "Excellent" Ad Strength; (4) Data Strength — implement sitewide tagging via Google Tag Gateway and connect offline sources through Data Manager API.
Google internal data (Apr 2024–Dec 2025): advertisers adopting ≥3 of 4 best practices saw on average >40% more conversions (as-of 2026-02-24, Google self-reported — methodology undisclosed, confidence: low-med). (Source: Registry — Demand Gen 2026-07-11)

View-through conversion (VTC) optimisation launched for YouTube within Demand Gen, enabling campaigns to optimise toward conversions from users who viewed but did not click (as-of 2026-04, Source: [[Registry — Demand Gen 2026-07-11]])

Google (Apr 2026): VTC optimisation "drives more conversions in less time." Source: Registry — Demand Gen 2026-07-11 Store Growers (2026-02-27): Recommends practitioners discount VTC-attributed impact significantly due to weak causal link between a view and a later conversion. Source: Practitioner — Demand Gen 2026-07-11

May/June 2026 — GDN migration

Starting June 2026, Google rolled out a migration tool moving eligible Google Display Network campaigns into Demand Gen. The GDN is not eliminated — advertisers can use channel controls to run exclusively on GDN within Demand Gen. Full transition expected to complete by 2027. (Source: Registry — Demand Gen 2026-07-11, blog.google 2026-05-26)

When using the official migration tool, up to 42 days of performance history transfers, minimising the learning phase. (Source: Common Thread Collective, 2026-06-27, via Registry — Demand Gen 2026-07-11)

Google data (Aug 2025): adding GDN to a Demand Gen campaign delivers on average a 9.5% increase in ROI. GoFood case: 24% CPA decrease and 19% higher conversion volume after adding GDN. (as-of 2026-05-26, Source: [[Registry — Demand Gen 2026-07-11]])

Audience targeting

Lookalike audiences are exclusively available in Demand Gen — they cannot be used in Performance Max (PMax), Search, or any other Google Ads campaign type. Advertisers upload a seed audience (customer list, website visitors, or app users) and Google builds an expanded audience with narrow, balanced, or broad expansion options. (Source: Registry — Demand Gen 2026-07-11, groas.com 2026-02-14)

Optimised targeting is on by default and allows Google's AI to expand beyond selected segments; turning it off enforces strict audience-only targeting. Practitioners note that enabling optimised targeting on campaigns designed to protect specific segments (remarketing lists, high-value customers) dilutes the audience and makes results uninterpretable. (Source: Practitioner — Demand Gen 2026-07-11)

Custom intent audiences — targeting based on recent Google search queries — are described by groas.com (2026-04-29) as the "single most underused YouTube targeting feature," enabling ads to reach people who just searched for competitors or category terms. (Source: YouTube — Demand Gen 2026-07-11)

New customer acquisition

Fospha study (n=127 retail brands across fashion, cosmetics, and consumer goods, 2024–2025): Demand Gen leads to an 18% higher share of conversions from new customers compared to the paid media average. (as-of 2026-04-23, Source: [[Registry — Demand Gen 2026-07-11]]; note: study cited by Google — independent methodology not publicly available)

Google internal data (Dec 2025): 68% of Demand Gen conversions came from users who had not seen the brand's ads on Google Search in the prior 30 days (as-of 2025-12, Source: [[Registry — Demand Gen 2026-07-11]], via groas.com 2026-02-14)

The December 2025 "68% incremental" figure pre-dates 2026 and may have shifted since the GDN migration and channel expansion.

Product feed integration

Connecting a Google Merchant Center product feed to Demand Gen is described as effectively mandatory for ecommerce by practitioners — without it, the algorithm has no specific product or price data to serve. (Source: Web — Demand Gen 2026-07-11)

Store Growers notes that adding product feeds from Merchant Center typically improves conversion rates by roughly 0.5–1 percentage points over standalone YouTube campaigns (as-of 2026-02-27). Google-cited figure: 33% increase in conversions when feeds are added, without a CPA increase — though Store Growers could not verify the primary source URL for this statistic. (Source: Web — Demand Gen 2026-07-11)

Attribution: Platform Comparable column

Google introduced a "Conversions (Platform Comparable)" reporting column for Demand Gen specifically to enable cross-platform comparison. It:

Removes other Google campaigns from the attribution path (giving Demand Gen full last-touch credit)
Includes view-through conversions (excluded from standard columns by default)
Mirrors how Meta and TikTok count conversions

This column is reporting-only and does not affect bidding. (Source: Practitioner — Demand Gen 2026-07-11, Registry — Demand Gen 2026-07-11)

Cypress North (Greg Finn, 2025-04) notes this as an unusually advertiser-friendly move from Google, given Google's historical opacity in attribution reporting.

Greg Finn's analysis dates from April 2025 — behaviour of the column may have evolved since.

Demand Gen vs Performance Max

Dimension	Demand Gen	Performance Max
Funnel position	Top/mid-funnel	Bottom-of-funnel (biases toward branded search + Shopping)
Placements	YouTube, Discover, Gmail, Maps, GDN	All Google surfaces including Search + Shopping
Audience control	Manual + lookalikes (exclusive)	"Optimised targeting" only (Google override)
Creative visibility	Per-asset performance reports	Limited visibility into running assets
Channel-level controls	Yes (as of March 2025)	No
Lookalike audiences	Yes (exclusive)	No

Store Growers: "PMax goes as low in the funnel as it possibly can. It loves branded search queries because those convert easily." (Source: Web — Demand Gen 2026-07-11)

Search Engine Land (2026-01-22): "Ecommerce brands that run both in coordinated full-funnel architecture consistently outperform those who choose one and ignore the other." (Source: Web — Demand Gen 2026-07-11)

Google's "Power Pack" recommendation (via groas.com, 2026-02-14): 50–60% of Google Ads budget to PMax (ecommerce), 30–40% to AI Max for Search, 10–20% to Demand Gen (as-of 2026-02-14, Source: [[Registry — Demand Gen 2026-07-11]])

Budget and setup requirements

Minimum recommended daily budget: $100/day or 20x the target CPA (Google recommendation, as-of 2026-02-27)
Store Growers: accounts below $75/day face slower algorithm learning and higher result variability; smaller stores should fix Performance Max (PMax) and Search profitability first
Learning period: 2–4 weeks; significant changes during this window reset the algorithm
Minimum 50 conversions in prior 30 days before using tROAS bidding; use Maximize Conversions with target CPA below that threshold
Minimum $5/day absolute floor enforced by Google from April 2026

(Source: Web — Demand Gen 2026-07-11, Practitioner — Demand Gen 2026-07-11)

Practitioner note (Brandcamp Digital, 2026-03): most advertisers who conclude "Demand Gen doesn't work" killed campaigns within 2–3 weeks, well before the algorithm stabilises on cold audiences. A minimum 60–90 day evaluation period is recommended.

Creative requirements and best practices

Creative requirements (as-of 2026-02-14, Source: [[Registry — Demand Gen 2026-07-11]]):

Landscape: 1200×628px, max 5MB
Square: 1200×1200px
Portrait: 960×1200px
Vertical: 9:16 (for YouTube Shorts, available since Feb 2025)
Video: 16:9, 9:16, 1:1 formats; carousels of 2–10 cards
Copy: up to 5 headlines (40 chars), 5 descriptions (90 chars)
Minimum: 3 assets per aspect ratio at launch; 5+ recommended

Multi-format approaches (video + images) generate approximately 20% more conversions at equivalent CPA vs video-only, per Google data cited by groas.com (as-of 2026-02-14).

June 2026: aspect ratio transformations now supported (vertical to square, vertical to landscape, square to landscape).

Store Growers estimates creative quality accounts for a "2–3x performance" difference between weak and strong creative. UGC-style (authentic, less produced) content outperforms traditional brand video on Demand Gen placements. (as-of 2026-02-27, Source: [[Practitioner — Demand Gen 2026-07-11]])

What practitioners report

Remarketing vs cold prospecting: Remarking audiences on Demand Gen routinely deliver 600–1000% ROAS; cold prospecting audiences are 3–5x weaker; practitioners recommend using Demand Gen primarily as a remarketing layer feeding lower-funnel Shopping/PMax rather than as a cold prospecting tool. (Store Growers, 2026-02-27, Source: Practitioner — Demand Gen 2026-07-11)
Measurement trap: Demand Gen campaigns are frequently judged with last-click ROAS, a metric suited to Search — the real contribution appears in blended CPA, branded search lift, retargeting pool quality, and reduced Search CPCs, none of which show in the Demand Gen report. (Brandcamp Digital, 2026-03, Source: Practitioner — Demand Gen 2026-07-11)
Channel launch order: Start with YouTube + Discover only; add Gmail and GDN only after positive ROAS is confirmed; default all-channels-on setting wastes budget on low-intent placements from day one. (Store Growers, 2026-02-27, Source: Practitioner — Demand Gen 2026-07-11)
Attribution problem unique to Google: Because Google Ads is strongest at bottom-of-funnel (Search, Shopping), those campaigns steal attribution credit from Demand Gen within the same account. Meta doesn't face this because it lacks bottom-funnel inventory. This makes Demand Gen's in-platform numbers look weaker than its true contribution. (Cypress North / Greg Finn, 2025-04)

Cypress North attribution analysis from April 2025 — relevant but pre-2026.

Fashion and retail fit

Store Growers explicitly lists fashion, lifestyle, travel, and automotive as Demand Gen's strongest product categories due to visual inventory appeal. Demand Gen is described as particularly strong for:

Launching new seasonal collections
Entering new markets
Driving seasonal spikes in demand
