What are Discovery Ads?
Discovery Ads is Google’s visual ad format that reaches users across YouTube, Gmail, and Google Discover. The format is designed to spark curiosity and purchase intent at the moments when you, as a user, are open to inspiration—not when you’re actively searching. This means that Discovery Ads act as a bridge between paid advertising and organic content, because they blend naturally into the feed you’re already scrolling through.
What makes Discovery Ads unique is that they are powered by artificial intelligence and machine learning. The system detects patterns in your behavior—for example, which videos you watch and which topics you interact with—and uses those signals to find new, relevant products that match your current interests. This happens without you, as an advertiser, having to define specific keywords. However, it does require a well-defined brand foundation and a design that can communicate visually. In other words, you need to both understand the algorithm’s logic and master the visual expression if you want to succeed with Discovery Ads.
How do you use Discovery Ads?
You use Discovery Ads to generate interest and engagement among users before they even start searching. While Search ads address a need that’s already been defined, Discovery Ads help plant the idea. To make this effective, you need to think like a content creator: What makes a person pause in a visual feed and interact with your brand? The combination of storytelling, design, and timing is crucial for the format to work.
Technically speaking, you set up the campaign directly in Google Ads and select an overall goal—typically conversions, traffic, or brand awareness. Then, you let the algorithm find the most relevant users based on their in-market signals—that is, indicators that they’re close to making a purchase. Here, you can build audiences that resemble your existing customers or let the system experiment with new segments on its own. It’s precisely this automation that sets Discovery Ads apart from traditional display campaigns.
That's Why You Should Use Discovery Ads
Discovery Ads give you access to Google’s most sought-after surfaces—feeds that billions of users visit every day. When you advertise here, you place your content right in the middle of contexts where users are already engaging with visually and personally curated content. This makes the format effective for cultivating new audiences—especially if you’re working with longer customer journeys where the relationship needs to be built gradually.
Google’s own performance metrics show that Discovery Ads can drive significantly more clicks and higher conversion rates than many display formats. This is due to the combination of AI, feed-based placement, and native design, which makes the ad feel like a natural part of the user experience. In other words, you get the performance of a paid format and the authenticity of an organic post.
What types and varieties are available?
You can choose from several creative formats that affect how your message is presented. Single-image ads work best when you want to highlight a clear “hero” product with minimal distractions. Carousel ads, on the other hand, give you room to tell a short story, since users can swipe through multiple images themselves—ideal if you want to showcase product variations or build a visual sequence. Video is the most engaging format, serving as a mini-commercial right in the middle of the feed.
Although the campaign is created as a single type in Google Ads, the format adapts to the context of each platform. On YouTube, the ad appears more visually engaging and dynamic, while Gmail uses a more text-based layout in the Promotions or Social tab. Therefore, you should think of Discovery Ads as a single format with context-dependent variations—not three separate solutions.
How do you use Discovery Ads in practice?
The first step is to define a clear goal for the campaign. Do you want to drive traffic, generate sales, or build brand awareness? Next, you upload creative assets to Google Ads, where the system automatically combines images, headlines, and descriptions into different versions. Google’s algorithms then test which combinations perform best among specific target audiences. This ongoing optimization happens in the background, so you can focus instead on refining your messaging and creative assets.
Data insights play a central role in the practical use of this format. Metrics such as click-through rate, conversion rate, and ROAS give you a quick overview of whether the ad is driving value. If you combine this with a clear content strategy and a solid grasp of SEO and brand identity, Discovery Ads become a natural extension of your overall marketing ecosystem. It’s about creating a consistent visual theme so that users recognize your brand across platforms.
What should you keep in mind?
Although Discovery Ads offer massive reach, a strategic approach is required to maximize their impact. The format isn’t designed for quick transactions, but rather to build interest and relationships over time. This means you’ll need to be patient with the algorithm, because the system spends the first few weeks learning which audiences respond best. This is often called the “learning phase” in the Google Ads environment, and results don’t stabilize until there’s enough data.
You should also pay attention to your creative output. The feed environment is highly competitive for attention, so images and headlines must be able to stand on their own and deliver value in just a few seconds. Test different combinations of colors, angles, and messages, and use AI-generated insights in Google Ads as a sounding board to refine them. Discovery Ads work best when creativity and data come together—just like in a modern, performance-driven marketing strategy.
