Moving Google Display to Demand Gen: What Advertisers Need to Know

Google is consolidating its display advertising into Demand Gen campaigns, a shift that affects targeting, creative requirements, bidding and measurement. Search Engine Land’s Sarah Vlietstra explains the change and its timeline, writing that “the biggest change in your newly created Demand Gen campaign will be the unavailability of certain bid strategies and ad formats.” This article breaks down what’s changing, what advertisers gain, and practical steps teams should take now to keep performance steady through the migration.

What’s happening and when

Google announced a phased migration of standalone Google Display Network (GDN) campaigns into Demand Gen. The rollout began with a migration tool appearing in accounts in June 2026 and Google plans to disable creation of new standalone Display campaigns in January 2027. Auto-migration of existing campaigns is expected later in 2027, although precise dates may vary by account.

The move is part of Google’s effort to unify campaign types and extend advertiser reach across additional inventory such as Discover and Maps while leveraging AI-driven optimization across YouTube and other visual surfaces. As Google put it in its announcement, “To help advertisers keep pace with evolving consumer behavior, Google Display Ads is transitioning into a more unified environment.”

Key changes to expect

Controls, bidding and formats

• Bid strategies: Some familiar bid strategies (Manual CPC, Viewable Impressions, Pay for Conversions) and controls such as bid adjustments, seasonality adjustments and portfolio bidding are not available in Demand Gen. You’ll need to shift to supported strategies like Target CPA, Target ROAS, or Maximize Clicks.
• Ad formats: Business data feeds, uploaded HTML5 ads and third-party creative are not supported initially (Google has said these will arrive later, with some formats targeted for late 2026), which affects advertisers relying on rich or third-party creatives.
• Billing: Google has already changed billing in some Demand Gen placements — for example, Discover placements using view-through-conversion optimization moved from CPC to CPM — so expect different billing behavior across networks.

Reach and inventory

Demand Gen expands reach beyond traditional Display placements into Discover, Maps and broader YouTube inventory. That opens doors for multi-channel storytelling and higher-funnel discovery, but it also means your campaign may deliver against different user intent signals and placements than before.

What advertisers gain

Demand Gen brings unified campaign management, more inventory, and generative creative tools. The platform better integrates video and visual assets, which can drive higher engagement across Google’s most visual surfaces. It also introduces features like view-through-conversion optimization that can attribute later conversions to impressions across YouTube or Discover.

Practical steps to prepare

Because performance can fluctuate after migration, proactive preparation is essential. Below are recommended actions for advertisers and agencies:

• Audit and prioritize creative assets: Identify and adapt high-performing images and videos. Convert or re-create HTML5 assets if necessary and prepare fallback static assets while waiting for full HTML5/third-party support.
• Seed audiences early: Lookalike Audiences have shifted toward broader “audience suggestions” and can take up to 96 hours to populate. Build and seed audiences in advance so your segments are ready when migration occurs.
• Plan bidding transitions: Map current bid strategies to supported Demand Gen options. Expect a learning period; if you relied on Manual CPC, prepare to switch to automated strategies and monitor performance closely.
• Run parallel tests: If possible, migrate a subset of campaigns first and run Demand Gen in parallel with remaining Display campaigns to compare performance and calibrate creative and bidding settings.
• Adjust measurement and attribution: Incorporate view-through conversions into your reporting where relevant and revisit attribution windows to better capture multi-touch journeys driven by impressions across YouTube and Discover.
• Monitor budget pacing and day-of migration effects: Google warns that budgets spent earlier in the day may not carry over to the migrated campaign. Monitor pacing immediately after migration and be ready to adjust daily budgets.

How to measure success post-migration

Focus on a mixed set of KPIs that reflect both upper-funnel engagement and bottom-funnel outcomes. Track impressions and view-through conversions alongside CTR, CPC (where applicable), conversion rate and CPA/ROAS. Use short A/B tests for creative variants and compare performance across placements (YouTube, Discover, Maps) to identify where your messaging resonates best.

Final thoughts

Transitioning Display into Demand Gen is more than a technical migration — it’s a strategic shift toward automation, broader inventory and richer creative formats. Sarah Vlietstra’s coverage in Search Engine Land captures the magnitude of the change: “the biggest change in your newly created Demand Gen campaign will be the unavailability of certain bid strategies and ad formats.” That limitation requires advertisers to rethink bidding and creative tactics, but the shift also opens new opportunities across Google’s visual inventory. Preparing early — seeding audiences, reworking creatives, and testing bidding strategies — will reduce disruption and position accounts to benefit from Demand Gen’s expanded reach and automation.
