How to Build a Successful Demand Gen Campaign in Google Ads

Demand Generation campaigns have become an increasingly important part of Google Ads. They give advertisers a way to reach potential customers beyond traditional Search campaigns, using visual content and audience targeting to generate interest before a user actively searches for a specific product or service.

Demand Gen can be particularly useful when a business wants to introduce its products to new audiences, build consideration and stay visible throughout a longer decision-⁠making process.

But the campaign type alone does not determine the result. Audience selection, creative, campaign structure, budget and ongoing optimization all play a role.

In this guide, we’ll look at how Demand Gen works, the audiences and ad formats available, and how to set up a campaign in Google Ads step by step.

What Is Demand Gen and How Is It Different from Lead Gen?

Demand Generation and Lead Generation are often used interchangeably, but they describe different marketing objectives.

Demand Generation is focused on creating awareness and interest. The goal is to introduce the product or service to relevant people and give them a reason to consider it, even if they are not yet actively looking for a specific solution.

This makes the creative especially important. The message needs to communicate the value of the product clearly and work in a visual environment where the user has not necessarily expressed direct search intent.

Lead Generation comes into play when the goal is more specific: turning that interest into an identifiable prospect. This may happen through a form submission, inquiry, registration or another conversion that gives the business a lead to follow up with.

In practice, the two can overlap. A Demand Gen campaign can also generate direct leads or sales. The difference is useful mainly because it helps define what the campaign is expected to achieve and how its performance should be evaluated.

Why Did Google Introduce Demand Gen Campaigns?

Demand Gen developed from Google’s Discovery campaigns as user behavior across Google properties continued to evolve.

People do not spend all of their time actively searching. They also discover content and products while watching YouTube, browsing feeds and interacting with other Google surfaces.

Demand Gen gives advertisers a way to reach people in those environments with more visual advertising formats.

The campaign type combines:

• visual assets, including images, carousels and video;
• audience targeting based on demographic, interest and behavioral signals;
• automated delivery and optimization;
• placements across Google’s visual surfaces;
• product information through Google Merchant Center where relevant.

This allows advertisers to reach potential customers before a specific search takes place and gives Demand Gen a different role from campaigns built primarily around existing search intent.

How Do Demand Gen Campaigns Work?

Demand Gen uses signals about users and their online behavior to identify audiences that may be relevant to the advertiser.

The campaign can work with information such as interests, demographic characteristics and previous interactions with the business. Google combines those inputs with its own signals and the campaign’s conversion data to determine how ads are delivered.

For example, a business offering digital marketing services may want to reach people who regularly consume content related to Google Ads, watch marketing videos on YouTube or show an interest in related topics.

These people may not be searching for an agency at that exact moment, but their behavior indicates that the subject is relevant to them.

This is where Demand Gen differs from Search. The campaign does not need to wait for the user to enter a specific query before the advertiser can reach them.

Automation plays an important role in delivery, but the quality of the advertiser’s inputs still matters. The campaign needs relevant audience signals, suitable creative and a conversion setup that tells Google what result it should work towards.

The Main Benefits of Demand Gen

Demand Gen gives advertisers several useful options within one campaign type.

Reach beyond active Search

The campaign can reach potential customers before they search for a specific product or service.

More visual ways to present the offer

Images, video and carousel formats give businesses more room to demonstrate a product, communicate a benefit or introduce the brand.

Audience personalization

Advertisers can work with demographic information, interests, behavior and previous interactions with the business.

Google Merchant Center integration

For eCommerce advertisers, product information can be included directly in the campaign.

Automated optimization

Google uses campaign and audience signals to optimize delivery towards the selected objective.

These capabilities make Demand Gen useful in accounts where visual communication and audience discovery can complement existing Search and Shopping activity.

What Audiences Can You Use?

Audience setup is one of the most important parts of a Demand Gen campaign.

Google provides several ways to build relevant audience groups, including:

• demographic segments such as age and gender;
• interest-⁠based audiences;
• custom audience segments;
• website visitors;
• people who have interacted with the company’s YouTube content;
• first-⁠party audience data available in the account.

The goal is not to add as many audiences as possible.

Start with groups that have a clear connection to the product or service. Then create enough separation to understand whether there are meaningful differences in performance.

Over-⁠segmentation can create the opposite problem. If every audience is too small, the campaign may not collect enough data for a useful comparison.

Once there is sufficient volume, compare the audiences against the metrics that matter for the campaign: conversions, CPA, conversion value or ROAS.

Ad Formats Available in Demand Gen

One of the main differences between Demand Gen and traditional text-⁠based advertising is the emphasis on visual creative.

Depending on the setup, advertisers can use:

Image Ads

A single visual combined with headlines, descriptions and a call to action.

This format works well when one image can communicate the product or message clearly.

Carousel Ads

Carousel ads allow several images or products to be presented within the same ad.

They can be useful when the advertiser wants to show a range of products, different features or several elements of the same offer.

Video Ads

Demand Gen can also use video content across relevant Google placements, including YouTube.

Video gives advertisers more space to demonstrate the product, explain a benefit or communicate a message that would be difficult to fit into a static image.

There is no single format that will always perform best. The stronger approach is to test the formats that make sense for the business and use the results to decide where to invest further.

How to Build a Demand Gen Strategy

Before creating the campaign in Google Ads, there are several decisions to make.

1. Define the objective

Decide what the campaign needs to achieve.

That could be traffic, conversions, sales, leads or another measurable objective.

The objective will influence the conversion setup, bidding strategy and the metrics used to evaluate the campaign later.

2. Understand the audience

Use the information already available in the account and analytics platforms such as GA4 to identify useful demographic and behavioral patterns.

Consider both potential new audiences and people who have already interacted with the business.

3. Prepare the creative

Choose images, video and messaging that fit the audience and the offer.

The creative should make the value of the product or service clear without relying on the user already knowing the brand.

4. Set the budget and targeting

Choose a budget that gives the campaign enough room to generate meaningful data and configure the audience targeting according to the strategy.

5. Measure and optimize

Once the campaign is running, compare audience and creative performance and continue testing.

CTR can help diagnose whether an ad is attracting attention, but conversions and business results should guide the larger optimization decisions when the campaign has a performance objective.

How to Create a Demand Gen Campaign in Google Ads

Once the strategy is clear, the campaign can be created directly in Google Ads.

Step 1: Create a New Campaign

Open Google Ads and select Create (+) → Campaign.

Step 2: Choose the Campaign Objective

Select the objective that corresponds to what you want the campaign to achieve.

Depending on the account and available options, this may be related to sales, leads, traffic or another relevant objective.

The choice should reflect what you ultimately want Google to optimize towards.

Step 3: Select Demand Gen

Choose Demand Gen as the campaign type.

At this stage, Google will take you into the Demand Gen campaign setup.

Step 4: Name the Campaign and Review the Conversion Goals

Give the campaign a clear name so that its purpose is easy to identify later.

Then review the selected conversion goals.

Make sure the campaign is optimizing towards the actions that actually correspond to its objective. For an eCommerce campaign, for example, a purchase should not be treated in the same way as a secondary website interaction.

Step 5: Set the Budget and Bidding Strategy

Set the campaign budget and choose the appropriate bidding strategy.

Depending on the campaign objective, this may involve optimizing for conversions or conversion value.

The choice should follow the result you want the campaign to generate rather than simply using the default setting without reviewing it.

Step 6: Configure Location, Language and Devices

Choose the geographic locations and languages relevant to the campaign.

Review the device settings and any other campaign-⁠level options that matter for the account.

These are straightforward settings, but they should still be checked carefully before launch. Incorrect geographic targeting can affect the entire campaign regardless of how well the audience and creative are configured.

Step 7: Define the Audience Targeting

Next, configure the audience.

Depending on the strategy, this can include demographic characteristics, interests, custom segments or people who have previously interacted with the business.

Keep the structure clear enough to understand which audiences are contributing to the results.

Step 8: Choose the Ad Format

Select the format you want to use: image, carousel or video.

Where suitable creative is available, testing more than one format can help identify how different audiences respond to the message.

Step 9: Add the Assets

Add the assets required for the selected format:

• headlines;
• descriptions;
• images;
• video;
• destination URLs;
• calls to action.

Review the ad preview before continuing. Check both the copy and how the visual assets appear in the available placements.

Step 10: Review and Publish

Before publishing, go through the complete campaign setup once again.

Check the conversion goals, budget, bidding, locations, languages, audiences, creative assets, URLs and calls to action.

If everything is correct, click Publish.

How to Optimize a Demand Gen Campaign

Launching the campaign is only the beginning.

Once enough data starts to accumulate, look at which audiences are generating the strongest results and which creative formats are contributing to conversions.

Audience performance can also be reviewed by demographic characteristics such as age and gender where there is enough data to make the comparison useful.

Creative should be reviewed in the same way. Test different messages and formats, then use the results to decide what should stay, what needs another variation and where budget can be used more effectively.

For campaigns focused on performance, monitor metrics such as:

• conversions;
• CPA;
• conversion value;
• ROAS;
• performance by audience;
• performance by creative.

CTR and engagement can still provide useful context, but they should not replace the main business metric.

Avoid reacting to every short-⁠term movement. Look for patterns in the data and make changes when there is enough evidence to support the decision.

What Should a Good Demand Gen Setup Answer?

Before launch – and again when reviewing performance – you should be able to answer a few basic questions.

Who are we trying to reach?

The selected audiences should have a clear connection to the product or service.

What are we showing them?

The creative should communicate the value clearly and give the campaign enough variation to test.

What do we want them to do?

The conversion goals should correspond to the actual objective of the campaign.

How will we decide whether the campaign is working?

The KPI should be clear before the campaign starts. Depending on the objective, that may be conversions, CPA, ROAS, conversion value or another relevant business metric.

If these answers are unclear, adding more audiences, more creative or more budget is unlikely to fix the underlying setup.

Demand Gen Is a Campaign Type – Not the Strategy Itself

Demand Gen expands the ways advertisers can reach potential customers within Google Ads. It combines visual formats, audience targeting and automated optimization, allowing businesses to reach relevant users without relying only on an active search.

Its role will be different from one account to another. It may support new customer acquisition, remarketing, product discovery or additional conversion volume alongside Search and Shopping.

What matters is deciding that role before the campaign goes live.

From there, the work is much more practical: choose the right audiences, prepare the creative, set the correct conversion goals, give the campaign enough data and optimize based on the results.
