What Are Google Discovery Ads? Everything You Need to Know in 2025

July 28, 2025

Ever feel like your ads are getting lost in the noise?

Between search fatigue and ad blindness, traditional PPC strategies aren’t always enough to reach today’s scrolling, skimming, and swiping consumers. That’s where Google Discovery Ads come in—designed to engage users before they even know what to search for.

In this guide, we’ll break down what Discovery Ads are, how they work, and why they’re one of the most powerful (yet underrated) tools in your paid media toolkit.

At Let’s Go Media, we help businesses turn awareness into action—Discovery Ads are one of our secret weapons. Here’s why they matter now more than ever.

What Are Google Discovery Ads?

Google Discovery Ads are visual, scroll-stopping display ads that appear across three high-traffic Google properties:

  • The Google Discover feed (on mobile devices)
  • YouTube Home and Watch Next feeds
  • The Gmail Promotions and Social tabs

Unlike traditional Search Ads that rely on keywords, Discovery Ads are intent-based—powered by Google’s machine learning to serve content aligned with user interests, behaviour, and past engagement.

They meet users where they are, not just when they’re searching, making them ideal for brand discovery, product launches, and top-of-funnel engagement.

Key Features of Discovery Ads

Let’s break down why Discovery Ads are catching marketers’ attention:

1. Massive Reach

With over 3 billion users across Gmail, YouTube, and Discover, Discovery Ads unlock broad visibility—without needing multiple ad formats or platforms.

2. Visually-Rich Formats

Discovery Ads use high-quality images and carousel formats that blend seamlessly with organic content. It’s advertising that doesn’t feel like advertising.

3. Automated Targeting

Instead of choosing keywords, Discovery Ads use audience signals, including:

  • Custom intent audiences
  • In-market audiences
  • Website visitors and re-marketing lists

This enables more personalised ad delivery without micromanaging campaigns.

4. Mobile-First Experience

Discovery Ads are designed for mobile scrolling, making them a great fit for users engaging on the go.

Discovery Ads vs. Display Ads: What’s the Difference?

While both ad types use visuals and Google’s ad network, there are key differences:

FeatureDiscovery AdsDisplay Ads
PlatformsDiscover, Gmail, YouTubeOver 2M websites & apps
TargetingAudience signals & machine learningManual targeting & placement
Ad FormatSingle image or carouselBanner, responsive, rich media
IntentMid to high intentBroader awareness targeting

Discovery Ads focus on conversion-ready users, while Display Ads cast a wider awareness net.

When to Use Google Discovery Ads

Discovery Ads are best for businesses looking to:

  • Increase brand awareness with visually appealing content
  • Introduce new products or services
  • Re-engage warm audiences (retargeting)
  • Drive traffic to landing pages or lead magnets

They shine in mid-funnel and retargeting strategies, especially when paired with high-quality creative and clear CTAs.

Best Practices for Discovery Ad Success

Want your Discovery Ads to convert? Follow these expert tips:

✅ Use High-Quality, Mobile-Optimised Images

Avoid stock-looking graphics. Authentic, crisp visuals perform best.

✅ Focus on Clear Messaging

Use short, punchy headlines that spark curiosity or offer value.

✅ Leverage Carousels for Storytelling

If you’re showcasing a product line or process, carousel formats allow for swipe-able, step-by-step engagement.

✅ Let Machine Learning Work

Avoid over-segmenting your audience. Google’s AI optimises better with larger data sets.

✅ Test, Analyse, Optimize

Use A/B testing for creatives and headlines. Watch engagement rates, CTR, and conversion metrics closely.

How Much Do Discovery Ads Cost?

Discovery Ads operate on a cost-per-click (CPC) or cost-per-thousand impressions (CPM) model, depending on your campaign objective.

While exact costs vary, they tend to be:

  • More affordable than Search Ads (especially for broad audience targeting)
  • Highly cost-efficient for retargeting

Like all paid media, performance depends on creative quality, audience selection, and landing page experience.

Are Discovery Ads Worth It?

Short answer: Absolutely.

If you’re looking to reach users earlier in the buying journey, build brand familiarity, and leverage Google’s smart targeting you’ll want Discovery Ads in your strategy.

They’re not meant to replace Search or Performance Max campaigns, but to complement them with visually rich, intent-driven engagement.
