Demand Gen Campaign – The Ultimate Guide

Google Ads has traditionally been strongest at capturing demand that already exists. A potential customer searches for a product, service or solution, and a Search advert competes for that enquiry at the point of intent.

Demand Gen works differently. It helps advertisers reach people while they are watching, browsing and discovering content—before or between active searches. The campaign type uses image, video, carousel and product-led creative across Google’s visual inventory, supported by audience data and automated bidding.

This makes Demand Gen Google’s closest equivalent to paid social advertising. It can introduce a brand, build consideration, reconnect with previous visitors and generate conversions. However, it should not automatically replace Search campaigns or be judged as though every impression came from a high-intent keyword.

The important question is not whether Demand Gen is better than Search, Display or Performance Max. It is whether the campaign has a clear role, suitable creative, reliable measurement and enough budget and conversion data to learn.

What Are Google Ads Demand Gen Campaigns?

Demand Gen is an audience-led Google Ads campaign type designed to generate engagement and action across visually rich Google surfaces. It evolved from Discovery campaigns and also became the destination for many of the performance-focused capabilities previously associated with Video Action campaigns.

Rather than being triggered primarily by a keyword, Demand Gen uses combinations of:

• first-party audience data;

• website and app activity;

• YouTube engagement;

• custom segments;

• interests and purchase intent;

• demographic information;

• Lookalike signals;

• contextual and behavioural signals;

• creative engagement; and

• Google’s prediction of conversion likelihood.

Google then uses these inputs with the campaign’s goal, bidding strategy and conversion data to decide where and when to serve an advert.

Demand Gen is therefore best understood as a creative and audience system—not simply another type of Display campaign. It can be used for prospecting, remarketing, product discovery, lead generation, ecommerce and customer acquisition, but its effectiveness depends heavily on how those jobs are separated and measured.

Where Do Demand Gen Ads Appear?

Google’s current Demand Gen documentation lists inventory across YouTube, Discover, Gmail, Maps and the Google Display Network. Eligible formats and exact availability vary by channel, advert type, market and campaign settings.

YouTube

Demand Gen can reach users across YouTube Home, Search, Watch Next, in-stream video and Shorts. This gives advertisers access to both feed-style discovery and video consumption.

The same creative should not be stretched indiscriminately across every YouTube environment. A vertical, fast-moving Shorts advert has a different job from a longer in-stream video or an image shown in the Home feed. The opening seconds, framing, captions and call to action should suit the placement.

Google Discover

Discover is a personalised content feed based on a user’s interests and activity. Demand Gen adverts appear alongside editorial-style recommendations, making strong imagery and a clear proposition especially important.

Discover is often suitable for product discovery, educational content and mid-funnel consideration. The user may be receptive but is not necessarily searching for the advertiser at that moment.

Gmail

Eligible adverts can appear in Gmail’s Promotions and Social tabs. This can work well for offers, product collections, remarketing and messages that benefit from an inbox-style environment.

Format availability can differ by region. In particular, advertisers serving European markets should check the current Gmail advert rules and preview actual eligibility rather than assuming every Demand Gen format will serve there.

Google Maps

Demand Gen can also access eligible Maps inventory. This can add useful visual reach for businesses with physical locations, although it does not turn Demand Gen into a keyword-led local Search campaign or replace a properly managed Google Business Profile.

Google Display Network and Video Partners

Demand Gen now extends beyond Google-owned feeds into eligible websites, apps and video-partner inventory. Google is also moving eligible Display activity into the Demand Gen campaign framework.

This creates more scale, but it can also change traffic quality and creative requirements. Advertisers should use channel controls, content suitability settings and placement reporting where available rather than treating all inventory as interchangeable.

Demand Gen Channel Controls

Demand Gen was initially associated with broad automated distribution, but advertisers now have more control over where adverts appear. Campaigns can use all eligible Google channels or manually select channels and, in some cases, sub-channels such as YouTube Shorts, in-stream or feed environments.

Channel selection should follow the campaign objective:

Selecting all channels can provide more inventory and help automated bidding find conversions. Separating channels can provide cleaner insight and better creative alignment. Neither approach is universally correct. The right structure depends on budget, volume and whether the account can support several independent learning systems.

Demand Gen vs Search Campaigns

Search and Demand Gen solve different problems.

For many lead-generation businesses, Search remains the strongest starting point because it can capture explicit commercial intent and provides comparatively direct control.

Demand Gen becomes more attractive when the business has already built reliable conversion tracking, understands its customers, has convincing visual creative and wants to grow beyond the available volume of relevant searches.

Demand Gen vs Performance Max

Demand Gen and Performance Max both use Google AI and serve across multiple surfaces, but their structure and strategic purpose differ.

Performance Max is designed to pursue conversion goals across nearly all Google Ads inventory. Demand Gen gives advertisers a more focused environment for audience and creative strategy across visual surfaces.

Running both can make sense, but overlap should be expected. The advertiser needs a measurement plan that considers incremental reach, brand demand and assisted conversions—not merely which campaign receives the final attributed conversion.

Demand Gen Advert Formats and Creative Requirements

Demand Gen supports several advert experiences. Eligibility varies by placement, so supplying a complete, high-quality asset set gives Google more opportunities to serve the intended message appropriately.

Single-Image Ads

Single-image adverts are useful for clear propositions, product highlights, proof points and offers. The main image should communicate the subject before the user reads the copy.

Google’s current Demand Gen asset specifications include these principal image ratios:

• square: 1:1;

• landscape: 1.91:1;

• portrait: 4:5; and

• vertical: 9:16, particularly for Shorts.

Use genuinely composed versions for each ratio. Automatic cropping of one landscape image rarely produces the strongest portrait or vertical advert.

Carousel Ads

Carousel adverts can present several related cards. They are useful for:

• a product range;

• multiple benefits;

• a step-by-step process;

• features or service categories;

• before-and-after storytelling; and

• a sequence that moves from problem to solution.

Each card should make sense individually while contributing to the wider story. Do not hide the core proposition exclusively in the final card.

Video Ads

Demand Gen supports horizontal, square and vertical video. Google specifies a minimum duration of five seconds, although videos shorter than ten seconds are not eligible for YouTube in-stream placements.

Effective video normally needs:

• an immediate visual hook;

• the product, service or problem introduced early;

• captions or on-screen text for sound-off viewing;

• branding that is visible but not obstructive;

• a message suited to the user’s stage of awareness; and

• a specific next action.

Vertical 9:16 creative should be produced for Shorts rather than treated as an afterthought. Important text and logos should remain within safe areas so interface elements do not cover them.

Product Feeds

Eligible retailers, hotels and other supported advertisers can connect product or inventory feeds. This allows Demand Gen to show relevant items using feed data alongside image or video assets.

A feed does not remove the need for creative strategy. Product titles, images, prices, availability, landing pages and categorisation still affect the usefulness of the advert experience.

Uploaded Display Ads

Demand Gen also supports eligible static and HTML5 Display assets for Google Display Network inventory. These use different dimensions and file requirements from standard Demand Gen images, so they should be prepared and quality-checked separately.

Audience Targeting and Signals

Demand Gen is audience-led, but modern Google Ads audiences do not always behave like fixed lists of people. Some settings operate as firm targeting; others guide the system towards likely converters and can expand beyond the initial input.

This distinction is essential. A selected audience should not automatically be interpreted as proof that every impression was delivered only to people inside that audience.

Demand Gen audience options can include:

• your data segments, such as website visitors and app users;

• Customer Match lists;

• YouTube users who interacted with a channel or videos;

• custom segments based on relevant interests, searches, websites or apps;

• in-market and affinity segments;

• life events and detailed demographics;

• combined audience criteria; and

• Lookalike segments created from first-party seed data.

Learn more about the wider relationship between audiences, signals and controls in our Google Ads targeting guide.

Lookalike Segments

Lookalike segments use first-party seed data—such as customers, converters, website users or YouTube engagers—to help find people with similar characteristics.

Google has been shifting Lookalike behaviour from strict similarity thresholds towards a suggestion model. Under this approach, the seed list and selected reach level guide the system, but Google may serve beyond the original similarity boundary when it predicts that doing so will help achieve the campaign goal.

This makes seed quality more important than list size alone. A list of confirmed customers, qualified opportunities or high-value buyers normally gives the system a clearer commercial pattern than a list containing every raw lead.

Advertisers who need tighter audience boundaries should inspect the current account controls rather than relying on older explanations of narrow, balanced and broad Lookalike percentages.

Optimised Targeting

Optimised targeting allows Google to reach people beyond manually selected audience segments when the system predicts they are likely to convert.

It can add scale, particularly when selected lists are small. It can also make audience-level interpretation less straightforward. Test it deliberately, document whether it is enabled, and assess downstream quality—not only the number or cost of initial conversions.

Bidding Strategies for Demand Gen

Demand Gen supports both performance and traffic objectives. Available strategies include:

The bidding strategy must match the result by which the campaign will be judged. A campaign using Maximise Clicks should not be expected to behave like Target CPA, and a campaign optimising every form submission cannot distinguish between poor leads and customers unless better outcomes are supplied.

Google applies specific eligibility requirements before Demand Gen can use Maximise Conversion Value or Target ROAS. Current guidance requires either enough recent valued conversions in the individual campaign or sufficient valued Demand Gen conversions across the account. Check Google’s current eligibility rules before planning a value-based launch.

Budget and the Learning Phase

There is no universal minimum budget that makes Demand Gen viable for every advertiser. The required amount depends on the achievable CPA, audience size, geography, sales value and selected bidding strategy.

The practical issue is whether the budget can generate enough events for the system to learn. Google recommends allowing around 50 conversion events before making major bidding changes. Its troubleshooting guidance also recommends materially larger budgets for conversion-based Demand Gen campaigns than many small advertisers expect.

This does not mean every account should blindly adopt a fixed daily figure. Instead:

1. Estimate a commercially realistic CPA or ROAS.

2. Calculate the budget needed to generate repeated conversions, not occasional isolated events.

3. Avoid dividing a modest budget across too many campaigns, channels and ad groups.

4. Use a shallower but meaningful conversion only if the final outcome is too infrequent to support learning.

5. Keep major budget, audience and bidding changes controlled while the campaign stabilises.

If the budget cannot support the likely conversion cost, a tightly controlled Search campaign or remarketing test may be a better starting point.

Conversion Tracking and Lead Quality

Demand Gen automation is only as commercially intelligent as the data supplied to it. Before launching, verify Google Ads conversion tracking and decide which outcomes should influence bidding.

For ecommerce, this normally means purchases with accurate revenue values. For lead generation, a basic form submission may be the first available signal, but it does not reveal whether the lead was relevant, contactable or profitable.

A stronger lead-generation measurement sequence is:

Google Ads interaction → Website lead → Qualified Lead → Sales Opportunity → Customer → Revenue

Offline conversion tracking and CRM integration can send later lifecycle outcomes back to Google Ads. This allows the bidding system to learn from qualified prospects, customers or revenue rather than treating every enquiry as equally valuable.

Use primary and secondary conversions carefully. Measuring every stage is useful, but making several stages from the same customer journey primary can inflate results and create confused optimisation signals.

Where outcomes have different commercial values, value-based bidding can help the campaign prioritise more valuable conversions. Values must be defensible and consistently applied; arbitrary scoring merely gives the algorithm precise-looking but misleading instructions.

How to Structure a Demand Gen Campaign

Campaign structure should separate meaningful business decisions without fragmenting data unnecessarily.

Create separate campaigns when you require different:

• budgets;

• conversion goals;

• bidding strategies or targets;

• countries, languages or operating regions;

• product lines with materially different margins;

• new-customer and existing-customer strategies; or

• channel-level tests that need independent budget control.

Within a campaign, use ad groups to organise genuinely different audiences, messages or channel choices. Avoid creating numerous nearly identical ad groups simply to recreate the microscopic segmentation of older Display advertising.

Prospecting and remarketing often deserve separation because they reach people at different levels of familiarity and should use different messages. Existing customers may also require exclusions unless repeat purchase or cross-selling is an explicit objective.

For a wider planning framework, see our guide to Google Ads account structure.

A Practical Full-Funnel Demand Gen Framework

Demand Gen can support several stages of the buying journey, but a single advert should not try to do everything.

Create Awareness

Use visually distinctive video or imagery to introduce a problem, category or brand. Optimise the creative for attention and comprehension, but do not confuse cheap views with commercial success.

Build Consideration

Show how the offer works, explain benefits, address objections and provide proof. Demonstrations, testimonials, comparisons, case studies and product sequences can help users move from recognition to evaluation.

Re-engage Interested Users

Use remarketing to reconnect with visitors, product viewers, video engagers or existing first-party audiences. Match the message to prior behaviour rather than repeating the original prospecting advert.

Convert and Measure

Use an appropriate landing page, clear call to action and accurate conversion tracking. Search and Performance Max may capture some of the demand influenced by Demand Gen, so evaluate cross-campaign effects without claiming every correlated conversion as incremental.

Measurement and Attribution

Demand Gen often influences a conversion before another campaign receives the final interaction. Last-click reporting can therefore understate its contribution—but generous attribution settings can also overstate it.

Review a balanced group of metrics:

• conversions and conversion value;

• cost per acquisition and return on ad spend;

• qualified-lead rate and customer acquisition cost;

• click-through and engagement rates;

• view-through and engaged-view conversions;

• new-customer contribution;

• brand-search and direct-traffic trends;

• assisted paths; and

• performance by channel, audience, creative and placement.

View-through conversions should be interpreted separately from click-through conversions. They can reveal influence, but exposure does not prove that the advert caused the sale.

For significant budget decisions, use experiments, conversion lift or other incrementality methods where available. Comparing geographically or temporally controlled groups can be more informative than relying entirely on platform attribution.

Demand Gen Best Practices

Give Every Campaign One Clear Commercial Job

Decide whether the campaign is intended to acquire new customers, remarket, generate qualified leads, produce sales, promote products or drive a defined traffic outcome. Select bidding, audiences and reporting around that goal.

Build Creative for the Placement

Supply landscape, square, portrait and vertical assets where relevant. Treat Shorts, in-stream, feeds and Display inventory as different viewing environments.

Lead With the Product or Problem

Feed-based advertising is fast. Make the subject clear immediately. Avoid slow logo reveals, generic stock imagery and introductory copy that requires several seconds to reach the point.

Use Enough Variation to Learn

Test different concepts, not merely minor colour or wording changes. Useful creative variables include the hook, offer, customer problem, product demonstration, proof, spokesperson and call to action.

Refresh Based on Evidence

Do not replace creative solely because a fixed number of weeks has elapsed. Monitor frequency, reach, engagement, conversion rate and asset reporting. Refresh when fatigue or declining marginal performance is visible.

Use High-Quality First-Party Data

Customer Match and Lookalike performance depends on the meaning of the seed data. Prioritise recent customers, valuable customers or consistently qualified leads over indiscriminate contact exports.

Protect Lead Quality

For lead generation, measure spam, duplicates, invalid enquiries, qualification rates and sales progression. A low reported CPA is not a success if the sales team cannot convert the leads.

Control Expansion Deliberately

Know whether Lookalikes, optimised targeting and all-channel distribution are expanding reach. Test expansion when measurement is reliable, then compare incremental volume with downstream quality.

Avoid Constant Changes

Large and frequent changes to budgets, goals, audiences and bid targets make performance harder to interpret and can disrupt learning. Make changes with a hypothesis and allow enough data to assess the result.

Audit Landing Pages as Carefully as Ads

Creative can generate attention, but the landing page must convert it. Message continuity, mobile speed, clarity, proof and form friction remain central to performance. Our guide to the three factors that determine Google Ads success explains the relationship between targeting, landing pages and AI bidding.

Common Demand Gen Mistakes

Treating Demand Gen as High-Intent Search

People browsing YouTube or Discover are not necessarily ready to buy. Use an appropriate proposition and compare results with realistic funnel expectations.

Launching Without Suitable Creative

One landscape image and a generic video rarely provide enough coverage. Poor creative cannot be rescued indefinitely by automated targeting.

Using Raw Leads as the Only Success Signal

If all form submissions are treated equally, Google may find more people who complete forms rather than more people who become customers. Feed qualified stages or revenue back where possible.

Fragmenting a Small Budget

Too many campaigns, ad groups, audiences and channel tests can leave every segment without enough data. Consolidate until the budget and conversion volume justify further separation.

Believing Audience Labels Are Absolute

Lookalike signals and optimised targeting can expand delivery. Check the actual controls and reporting in the account.

Comparing Only Last-Click CPA

Demand Gen may contribute earlier in the journey. Equally, view-through attribution may exaggerate influence. Use several measurement views and test incrementality where the investment warrants it.

Allowing Automatic Changes Without Review

Creative enhancements and generated assets can increase coverage, but they can also change how the brand, product or offer is presented. Review available controls, previews and asset reporting.

When Should You Use Demand Gen?

Demand Gen is worth testing when:

• relevant Search demand is limited or expensive;

• the product or service benefits from demonstration or visual storytelling;

• the business has strong creative assets;

• conversion tracking is accurate;

• first-party audience data is available;

• remarketing audiences need additional reach;

• ecommerce products are suitable for discovery; or

• the budget can generate enough activity for meaningful learning.

It may be a poor starting point when:

• the business only needs immediate, high-intent enquiries;

• the available budget is small relative to the expected CPA;

• tracking is incomplete or duplicated;

• lead quality is not measured;

• there is no capacity to produce and refresh creative; or

• the offer, landing page or commercial proposition is still unproven.

For many small lead-generation advertisers, the sensible sequence is to establish controlled Search performance first, improve tracking and landing pages, and then test Demand Gen as an additional source of reach—not as an automatic replacement.

How Demand Gen Fits With Other Google Ads Campaigns

A balanced account might use:

• Search to capture explicit intent;

• Standard Shopping or Performance Max to sell products;

• Demand Gen to create consideration and reconnect with audiences;

• Video campaigns for reach, awareness or YouTube-specific objectives; and

• remarketing strategies across eligible campaign types.

The mix should reflect the customer journey, not a desire to activate every available campaign type. Google Ads performs best when each campaign has a distinct job and all campaigns learn from a consistent definition of business value.

Conclusion

Demand Gen gives advertisers a powerful way to reach potential customers across YouTube, Discover, Gmail, Maps and Google Display Network inventory. It combines visual creative, first-party audience data, automated bidding and cross-channel distribution in a campaign type designed to influence and convert demand beyond the search results page.

Its automation does not remove the need for strategy. Strong performance still depends on a clear objective, suitable channel selection, placement-specific creative, accurate conversion tracking, high-quality audience inputs and enough data to support learning.

For ecommerce and visually led brands, Demand Gen can expand product discovery and customer acquisition. For lead-generation businesses, it can support prospecting and remarketing—but should be judged by qualified leads, customers and revenue rather than cheap form submissions alone.

The best use of Demand Gen is not to replace Search indiscriminately. It is to add a controlled system for creating, influencing and reactivating demand while Search and other campaigns capture the intent that follows.

Frequently Asked Questions

Has Demand Gen Replaced Discovery Campaigns?

Yes. Discovery campaigns were upgraded to Demand Gen. Demand Gen also became the upgrade path for Video Action campaigns and is taking on eligible Display activity as Google consolidates more visual performance inventory within the campaign type.

Does Demand Gen Include the Google Display Network?

Yes. Eligible Demand Gen campaigns can use Google Display Network websites and apps. Advertisers can use channel controls to decide whether this inventory should be included.

Can Demand Gen Show on Google Search?

Demand Gen can appear in visual environments including YouTube Search results, but it is not a keyword-led Google Search campaign. Use Search campaigns to target explicit queries on the main search results page.

Is Demand Gen Better Than Performance Max?

Neither is universally better. Demand Gen provides a more audience- and creative-led route across visual inventory, while Performance Max pursues conversion goals across a wider range of Google channels, including Search and Shopping inventory.

Can Demand Gen Be Used for Lead Generation?

Yes, but lead quality must be measured. Where possible, connect the campaign to CRM lifecycle stages and offline conversions so optimisation can learn from Qualified Leads, Sales Opportunities, customers or revenue.

How Much Budget Does Demand Gen Need?

There is no single suitable amount for every advertiser. Budget should be considered in relation to the realistic CPA or ROAS and the number of conversions required for learning. A budget that can generate only occasional conversions is unlikely to provide stable optimisation.

Does Demand Gen Support Lookalike Audiences?

Yes. Demand Gen supports Lookalike segments built from first-party seed data. Google is increasingly using these as audience suggestions rather than strict similarity boundaries, so advertisers should check the current controls and interpret audience reports accordingly.

Should Demand Gen Be Used Before Search?

Usually not for a small lead-generation business that depends on immediate intent. Search is often the more controllable starting point. Demand Gen becomes more compelling when tracking, creative, audience data and budget are mature enough to support prospecting or broader remarketing.
