Google Discovery Ads leverage the power of machine learning and user behaviour analysis to deliver personalised ads across multiple Google platforms. By harnessing user intent signals, these ads appear seamlessly in Gmail, Discover feed, and YouTube Home Feed, offering advertisers immense reach and engagement opportunities. With Discovery Ads, marketers can tap into Google’s vast audience network and deliver visually captivating ads to potential customers.

On the other hand, Google Display Ads empower advertisers to showcase their brand through visually appealing banners, images, and videos. With the extensive reach of the Google Display Network, spanning millions of websites and apps, Display Ads allow for precise targeting options, captivating audiences at various stages of the marketing funnel. This campaign type offers flexibility, enabling marketers to tailor their ads to specific audiences and placements.

Comparing Appearance and Placements:

While both Discovery Ads and Display Ads offer visually engaging formats, they differ in terms of appearance and placements. Discovery Ads captivate users with immersive, swipeable carousels that seamlessly blend with the platform’s content. These ads appear in the Discover feed, Gmail Promotions and Social tabs, and YouTube Home Feed, providing an unobtrusive and engaging user experience.

Display Ads, on the other hand, offer a range of formats, including banners, images, and videos, that are displayed across millions of websites and apps within the Google Display Network. This campaign type provides advertisers with more control over ad placement, allowing them to select specific websites or topics relevant to their target audience.

Targeting Options: Finding the Right Audience:

Targeting plays a vital role in the success of any advertising campaign. With Google Display Ads, advertisers have the flexibility to choose from a wide range of audience and content targeting options. From demographics and affinity to in-market and custom segments, marketers can precisely define their target audience based on their preferences.

In contrast, Google Discovery Ads solely focus on audience targeting, offering an array of options, including demographics, affinity, in-market segments, and custom segments. While Discovery Ads lack content targeting, the available audience targeting options ensure advertisers can reach their desired audience effectively.

Performance Metrics: Decoding Success Factors:

  • Save

Understanding the performance metrics of your ad campaigns is crucial for optimization and achieving your desired outcomes. In the case of Display Ads, traditional metrics like click-through rate (CTR) and cost per click (CPC) are essential. However, with Discovery Ads, additional metrics come into play.

  • Save

Interactions and engagements are key metrics for Discovery Ads. Interactions include clicks that direct users to your website or other interactions within Google Ads, such as opening a Gmail ad or liking a Discovery ad. Engagements encompass valuable actions like watching a certain duration of a video or forwarding a Gmail ad. Monitoring these metrics provides insights into user engagement, interaction rate, and cost per engagement, allowing for effective troubleshooting and optimization.

Optimising Performance: The Creative Edge:

  • Save

Creative elements play a significant role in the success of both Discovery Ads and Display Ads. Google’s research highlights key best practices for ad creatives. For Discovery Ads, single-object-focused, centrally framed images depicting real humans in real-life contexts tend to perform well. Minimal text overlays are recommended, with headlines and descriptions of medium length, specificity, and a clear call to action.

  • Save

Display Ads offer more creative flexibility, with various formats and sizes available. From eye-catching banners to captivating videos, the key is to create visually appealing content that aligns with your brand and resonates with your target audience. Testing different creatives and monitoring performance can help optimise your Display Ads for maximum impact.

When to Use Discovery Ads vs. Display Ads:

  • Save

Determining when to use Discovery Ads versus Display Ads can significantly impact the success of your campaigns. Discovery campaigns excel with conversion-based Smart Bidding strategies such as Maximise Conversions or Maximise Conversion Value. Their optimization capabilities, accurate audience matching, and high-quality traffic make them ideal for testing before Display campaigns. Although Discovery campaigns may have a higher cost per click, they often deliver higher conversion rates and better lead quality.

  • Save

Display campaigns, on the other hand, offer versatility and can be used with various bid strategies based on your campaign objectives. From viewable CPM for top-of-funnel initiatives to Maximise Conversions or Maximise Conversion Value for bottom-of-funnel goals, Display Ads provide ample options for performance optimization.


Understanding the similarities, differences, and suitable use cases for Google Discovery Ads and Display Ads is essential for optimising your advertising strategy. By leveraging the power of visually captivating content, precise targeting, and performance metrics, you can maximise your campaign’s impact and drive meaningful results. Incorporate these actionable insights into your Google Ads strategy to unlock the true potential of Discovery and Display campaigns.
