Demand Gen campaigns force a hard question on every PPC team: what do you do when there is no search query to bid on? For years, paid search let advertisers sit back and catch demand that customers already declared by typing a keyword. Demand Gen flips that. It places your ads in front of people on YouTube, Discover, and Gmail before they search for anything, which means the campaign has to create the want rather than just capture it. That shift rewards creative, audience insight, and full-funnel measurement over keyword tactics. This guide explains how Demand Gen campaigns work, how they differ from Search and Performance Max, what the benchmarks look like, and how to prove they pay.
Key takeaways
- Demand Gen campaigns run on YouTube, Discover, and Gmail to reach people before they search, so they create demand instead of capturing it.
- They demand strong creative and audience research, not keyword lists, which is why PPC can no longer hide behind search intent.
- Search still owns declared intent (roughly 6.66% CTR), while Demand Gen trades a lower click rate for cheaper, upper-funnel reach.
- Last-click attribution undervalues Demand Gen, so measure view-through conversions, brand search lift, and assisted paths.
- Google found that pairing image and video assets lifts conversions by about 6% for the same spend.
What are Google Demand Gen campaigns?
Demand Gen is Google’s upper-funnel, visual-first campaign type. It shows image and video ads across YouTube (in-feed, in-stream, and Shorts), the Discover feed, Gmail, and the Google Display Network, reaching users who are browsing and watching rather than searching. Google built it to replace Discovery ads and to give social-style prospecting a home inside Google Ads.
Three parts define the format:
- Audiences over keywords. You target lookalike segments, Customer Match lists, and custom intent audiences, then let Google expand from there. There is no keyword to declare intent for you.
- Creative that carries the message. Ads combine images, video, headlines, and an optional product feed, so the visual does the persuading a search headline never had to.
- Broad, browsable placements. Your ad sits inside a feed next to content people chose to consume, which is closer to the way Meta ads interrupt a scroll than to a results page.
Why PPC can no longer hide behind search intent
Search advertising has always carried a comfortable crutch. Someone types “emergency plumber near me,” and the keyword hands you their intent on a plate. The ad barely has to work. Demand Gen removes that scaffolding. Nobody on Discover asked for your product, so the campaign has to name a problem the viewer feels and make them care in a few seconds.
That changes the job. Instead of tuning match types and bids, PPC teams now write creative briefs, study customer reviews, and frame ads around problems rather than features. Google’s own global data shows the payoff for getting creative right: advertisers who ran both image and video assets saw about 6% more conversions for the same spend compared to image-only campaigns. Reaching buyers this way, before they ever type a query, is the same logic behind non-linear targeting that reaches buyers keywords miss.
Demand Gen vs Search vs Performance Max: how do they differ?
These three campaign types own different jobs in the funnel. Judging Demand Gen by Search metrics will always make it look weak, because they are not competing for the same click.
| Campaign type | Funnel role | Typical CTR | Typical CPC | Best for |
|---|---|---|---|---|
| Search | Capture declared intent | ~6.66% | ~$5.26 | Bottom-funnel, ready-to-buy queries |
| Demand Gen | Create demand | ~0.5% to 2% | ~$0.30 to $1.50 | Awareness and consideration on YouTube, Discover, Gmail |
| Performance Max | Convert across all inventory | Varies by channel | Varies by channel | Blended conversion goals with feed and Shopping |
Performance Max now drives close to 45% of all Google Ads conversions, and most accounts run it alongside other campaign types rather than alone. The difference that matters for planning: Demand Gen gives you channel-level placement control and transparent creative data, while Performance Max keeps its automation mostly hidden.

What do Demand Gen campaigns cost, and how do you bid?
Demand Gen buys cheaper clicks than Search, but it asks for patience and volume. Plan around a few practical guardrails:
- Bidding: target ROAS suits ecommerce, while Maximize Conversions with a target CPA fits lead generation. tROAS performs best once the account has 50 or more conversions in the past 30 days.
- Budget floor: allow roughly $100 per day, or about 20 times your target CPA, so the system has room to learn.
- Learning period: give the campaign 4 to 6 weeks before you judge it. Post-learning ROAS commonly lands in the 2x to 5x range once creative and audiences settle.
Resist the urge to pour the whole budget in on day one and then panic. That pattern backfires here for the same reasons it does everywhere else, which we cover in why frontloading ad spend usually backfires.
How do you measure Demand Gen when last-click fails?
Last-click attribution is the fastest way to kill a Demand Gen campaign that is actually working. The channel plants a seed on YouTube or Discover, the buyer searches your brand a week later, and Google hands the credit to branded search. Fospha research has flagged exactly this, showing that last-click can significantly undervalue YouTube and Demand Gen.
Measure contribution instead of clicks:
- Track view-through and engaged-view conversions, not just direct clicks.
- Watch brand search volume for lift after a Demand Gen flight goes live.
- Read assisted conversions and full customer journeys in GA4.
- Run a lift study or a geo holdout when spend justifies it.
The results reward the effort when you measure the full journey. Zoopla, in a Google case study, reported a 14% increase in valuation searches and a 28% increase in leads from Demand Gen. Attention standards are catching up too, with the IAB and Media Rating Council introducing standardized attention measurement guidelines in late 2025.
Demand Gen best practices for 2026
- Lead with the problem, not the product, and test problem-led creative against product-led versions.
- Supply every aspect ratio Google asks for: vertical, square, and landscape, plus video and image together.
- Start on YouTube and Discover, then expand placements once performance stabilizes.
- Connect a Merchant Center product feed for retail campaigns.
- Build separate ad groups for lookalike prospecting, custom intent, and remarketing so each audience tier reports cleanly.
- Exclude existing customers when the goal is new demand.
Common Demand Gen mistakes to avoid
- Grading the campaign on last-click ROAS and cutting it before the seed pays off.
- Uploading one image and calling the creative done.
- Setting a budget too thin for the algorithm to exit learning.
- Copying Search intent expectations onto an awareness channel.
- Ignoring the audience insights Google surfaces, which often reveal segments you never targeted on purpose.
Frequently asked questions
What is the difference between Demand Gen and Performance Max?
Demand Gen focuses on upper-funnel demand creation across YouTube, Discover, and Gmail, and it gives you audience and placement controls plus transparent creative data. Performance Max spans all Google inventory to chase conversions, with far less visibility into where and how it runs.
Are Demand Gen campaigns worth it?
For brands that need to build awareness and feed their Search and Shopping campaigns with new demand, yes. They are less useful if you only want to harvest existing bottom-funnel intent, which Search still does best.
What is the minimum budget for a Demand Gen campaign?
Plan for roughly $100 per day, or about 20 times your target CPA, and expect a 4 to 6 week learning period before the numbers settle.
How is Demand Gen different from the old Discovery campaigns?
Demand Gen replaced Discovery ads and added YouTube video and Shorts inventory, more creative formats, lookalike audiences, and better experimentation and reporting.
Should I use last-click attribution for Demand Gen?
No. Last-click undervalues upper-funnel campaigns. Use data-driven attribution, view-through conversions, brand search lift, and lift studies to see the true contribution.
The bottom line
Demand Gen campaigns close the era when a keyword could do the selling for you. The advertisers who win with them treat creative as the media buy, research the customer instead of the query, and measure the whole journey rather than the last click. Get those three right, and Demand Gen becomes the engine that fills the top of your funnel and makes every Search and Shopping campaign downstream work harder.
