Google Demand Gen Campaigns for Local Business (2026)
Part of the guide: Local Marketing Strategy
Should a local business run Google Demand Gen campaigns? Only after Search ads and your Google Business Profile are working, and only with a budget big enough to leave the learning phase. Demand Gen shows image and video ads on YouTube, Discover, Gmail and the Google Display Network to people who are not searching yet. Google's own guidance says to budget at least 10 times your target cost per action and to allow about 50 conversions before changing bids. For a small local account, that maths decides everything.
This guide uses Google's help pages and one 2026 benchmark report, each linked below. Worked examples are labelled as assumptions.

What Is a Demand Gen Campaign?
Google describes Demand Gen as a campaign type that combines video and image assets on visual, discovery-oriented surfaces. Its AI serves the best-performing visuals to people likely to be interested, even if they are not searching (Google Ads Help: About Demand Gen campaigns).
The detailed channel list names YouTube (including Shorts), Discover, Gmail and the Google Display Network. The page's introduction also mentions Maps, but the channel list does not, so Maps delivery is not confirmed there. Check the channel options in your own campaign before you count on it.
Asset requirements, per the same page:
- Images: landscape 1.91:1, portrait 4:5, square 1:1, plus a 1:1 logo.
- Video: landscape, portrait, square and vertical formats.
- Carousel: 2 to 10 image cards.
- Text: headline, description, business name, call to action and final URL.
Google recommends using both image and video assets for better performance. Discovery campaigns were upgraded to Demand Gen; Google's upgrade page says no action is needed from advertisers (Google Ads Help: Upgrade Discovery ads to Demand Gen). The same Demand Gen page says Display campaigns are also moving to Demand Gen, with voluntary migration starting in June 2026.
How Is Demand Gen Different From Search Ads?
Search catches demand that already exists. Demand Gen interrupts people who were watching a video or checking email. That changes what you should expect.
| Search ads | Demand Gen | |
|---|---|---|
| Who sees it | People typing a query | People browsing YouTube, Discover, Gmail |
| Creative needed | Text | Images and video |
| Typical job | Capture ready buyers | Introduce, retarget, promote an offer |
| First test | Keywords and location | Creative and audience |
The cost gap is visible in LocaliQ's 2026 search benchmarks, which give a sense of what a lead costs when someone is already looking. Median cost per lead was $31.50 for Animals and Pets, $39.25 for Beauty and Personal Care, $30.57 for Restaurants and Food and $67.36 for Health and Fitness (LocaliQ search advertising benchmarks). Those are Search figures. LocaliQ does not publish Demand Gen benchmarks on that page, so none are quoted here.
How Much Budget Does Demand Gen Need?
Two numbers matter. The first is a floor. Google told developers that Demand Gen campaigns need a daily budget of at least 5 USD or the local equivalent for campaigns managed through the Google Ads API, from April 1, 2026 (PPC Land report on the Google Ads Developer Blog notice). That is second-hand reporting, and it is a floor, not advice.
The second is Google's own guidance. For target CPA bidding, it recommends a budget "at least 10 times your target CPA". It also says to allow around 50 conversion events for the learning period before changing bids, and to give ads at least 24 hours for review (Google Ads Help: Create a Demand Gen campaign).
Put those together and the rule is blunt. A low target CPA with a tiny daily budget cannot reach 50 conversions quickly.
Worked Example: What Does the 10x Rule Cost?
All figures below are assumptions for illustration, not results.
| Salon | Pet groomer | Fitness studio | |
|---|---|---|---|
| Target CPA (assumption) | $40 | $30 | $65 |
| Daily budget at 10x | $400 | $300 | $650 |
| Spend to reach 50 conversions | $2,000 | $1,500 | $3,250 |
| Days to reach 50 at $15 a day | 133 | 100 | 217 |
How to read it: a business spending $450 a month ($15 a day) would take months to finish the learning period on any of these targets. That does not make Demand Gen useless. It means a small budget is better spent where intent is higher, and Demand Gen should wait until Search is already converting.
A Simple Rule
If your total Google Ads budget is under roughly 10 times your target CPA per day, put the money into Search and your Google Business Profile first. Use Demand Gen when you have a creative asset worth showing and a conversion goal you can measure.
When Does Demand Gen Make Sense for a Local Business?
Three situations justify a test:
- A seasonal or launch offer. A new class timetable, a summer menu or a grand opening has a clear message and an end date.
- Warm audiences. Google says you can build lookalike segments from past purchasers, website visitors or YouTube channel viewers. A small customer list gives the model less to learn from, so treat this as a test.
- Visual businesses with spare footage. Salons, groomers and studios already film their work.
Situations to skip it:
- No tracked conversion, such as a booking form or call.
- A website that cannot take a booking on a phone.
- A monthly ad budget so small that one test would exhaust it.
How Do You Target Locally in Demand Gen?
By default, location and language targeting sit at the ad group level, set to all locations and all languages. Google says to use campaign-level targeting only if you need a radius around a location, and warns that you cannot switch back to ad group level after publishing (Google Ads Help: Create a Demand Gen campaign). Decide before you publish.
Practical steps:
- Set a radius or a list of cities that matches the area you can actually serve.
- Upload vertical video and square or landscape images, so the AI has options for each surface.
- Track a booking or call as the conversion. Count only that.
- Choose a bid strategy that fits your data. The page lists maximise conversions, target CPA, maximise clicks, maximise conversion value and target ROAS.
- Wait for about 50 conversions, or a few weeks of data, before judging.

What Should You Measure?
Do not judge a Demand Gen campaign only by clicks. Track three things:
- Cost per booking or call, compared with your Search campaigns.
- Branded searches for your business name over the test period, as a rough signal that people remember you.
- Assisted results in your analytics, where a visitor first saw the ad and booked later by another route.
Brand search lift is an inference from your own data, not a Google-published Demand Gen metric. If you cannot see a booking source at all, fix tracking first with our budget planning guide as a starting point.
FAQ
Q: Is Demand Gen the same as Performance Max?
A: No. Google describes Demand Gen as a campaign for visual, discovery-oriented surfaces where you supply image and video assets. Check Google's current help pages for how it differs from other campaign types in your account.
Q: Does Demand Gen show on Google Maps?
A: Google's overview page mentions Maps in its introduction, but the channel list does not include it. Look at the channel options in your campaign setup before assuming Maps delivery.
Q: What is the minimum daily budget?
A: PPC Land reports Google set a 5 USD daily minimum for Demand Gen campaigns through the Google Ads API from April 1, 2026. That is a floor. Google's own guidance for target CPA bidding is a budget at least 10 times your target CPA.
Q: Can I use customer lists?
A: Google says Demand Gen supports custom audiences and lookalike segments built from past purchasers, website visitors or YouTube channel viewers. Check the audience size requirements in your account before you plan around a small list.
Q: Should a coffee shop or salon start here?
A: Most should start with Search ads and a complete Google Business Profile. Our Google Business Profile checklist is the cheaper first step.
