Demand Gen Campaigns

Demand Gen campaigns are a Google Ads campaign type that shows image and video ads in visual, scrolling places such as YouTube, YouTube Shorts, Discover and Gmail, to people who are not yet searching for your product. They are built to create interest and new customers, while Search campaigns capture people who are already looking.

• Placements: YouTube in-stream, in-feed and Shorts, Discover, Gmail, and the Display network.
• Formats: Single image, carousel, video and product ads from a Merchant Center feed.
• Audiences: Lookalike segments, your own customer lists, and interest based segments.
• Goals: Conversions, clicks or conversion value, using automated bidding.
• History: It replaced Discovery campaigns, and later absorbed Video action campaigns.

This lesson follows one example: a D2C snack brand from Mumbai that sells roasted makhana and high protein snack bars. Its Search ads work for people who type its name, but few people know the brand yet, so it wants to reach fitness-minded buyers before they search.

Key Characteristics of Demand Gen Campaigns

• Visual first: Ads are images and videos designed for feeds, not text for search results.
• Upper and middle funnel: They work at the awareness and consideration stages of the marketing funnel.
• Audience control: You choose audiences, including lookalikes, rather than handing everything to the system.
• Channel control: You can limit which Google surfaces the campaign uses.
• Creative testing: Easy to compare images and videos, since each ad group can hold several ads.

How Demand Gen Campaigns Work

1. Choose a goal: The snack brand chooses conversions, with online purchase as the goal, and Maximize conversions bidding.
2. Build audiences: It uploads a list of past buyers who agreed to marketing, with consent recorded, as a seed for a lookalike segment. Customer lists must follow Google's policy and Indian data protection rules, covered in first-party data strategy.
3. Add creative: Square and portrait images of the bars, a vertical 15 second video for Shorts, and a horizontal video for in-stream placements.
4. Set budget: A daily budget that follows Google's Demand Gen guidance, so the campaign has room to learn.
5. Serve ads: Google shows the ads in feeds and on YouTube to people in or similar to the chosen audiences.
6. Measure: Purchases, views and new visitors are compared with Search results for the same period.

Example: Demand Gen for a Mumbai Snack Brand

• Audiences: One ad group targets a lookalike of past buyers, another targets people interested in fitness and healthy eating.
• Creative: Real videos of the product, shot on a phone in a real gym, perform the job of honest demonstration. The brand plans them with ideas from AI video generation for ads, but only publishes footage of the real product.
• Claims: Protein numbers on the ad match the pack, and any comparison is checked against the label.
• Search next door: A brand Search campaign captures people who search the name after seeing the video.
• Reading results: The team checks conversions and also the rise in brand searches, while knowing that the second is only a sign, not proof, of impact.

Benefits of Demand Gen Campaigns

• New buyers: Reaches people who would never find the brand through search.
• Rich formats: Video and image formats show the product and its use.
• Audience tools: Lookalikes extend reach from the customers you already have.
• Creative learning: Shows which messages and visuals stop people scrolling.

Limitations of Demand Gen Campaigns

• Lower intent: People are browsing, not searching, so conversion rates are usually lower than Search.
• Creative cost: Needs a steady supply of good images and videos.
• Attribution gaps: Many viewers buy later through another channel, so last click reports undercount the effect.
• Learning needs: Small budgets can struggle to give the system enough conversions.

How AI Changes Demand Gen Campaigns

What AI Automates Now

Google's AI decides who sees each ad, which placement to use and how much to bid. It builds lookalike audiences from seed lists, and generative tools can suggest image variations and crop assets for each format. Longer video guidance sits in YouTube Ads.

What Still Needs a Human

People still write the idea behind each ad, film honest product footage, pick the audiences worth seeding, and check that claims such as protein per bar are true. AI can resize a video, but it cannot decide what makes a Mumbai office worker want a healthier snack.

Risk to Watch

AI-generated product images can show something different from the real product, such as a bigger bar or different packaging. That misleads buyers and can break advertising rules. Use real product images, and disclose AI-generated people or scenes where required.

Do It with AI

Use this prompt to plan creative for one Demand Gen campaign. It works in ChatGPT, Claude or Gemini.

1. Fill in real product facts from the pack and the site.
2. Run the prompt and remove any claim you cannot prove.
3. Shoot the chosen scripts with the real product.
4. Launch two angles in separate ad groups and compare them after a few weeks.

Check Before You Use It

• Facts: Nutrition numbers must match the pack label exactly.
• Brand fit: Keep the brand's tone, whether playful or serious, in every script.
• Compliance: Follow food advertising rules on health claims, and label AI-generated people or scenes.
