Mastering Google Discovery Ads: Boost visibility and drive conversions in 2025

Google Discovery Ads are a strong tool for brands to reach users when they passively browse platforms like the Google Discover feed, YouTube, and Gmail.

These visually engaging ads blend seamlessly into users’ feeds and use machine learning to tailor content based on interests and behavior.

Unlike traditional search ads, Discovery Ads focus on brand awareness and conversions through immersive, non-disruptive experiences.

Their impact is reflected in Google’s $305.63 billion ad revenue in 2023, with Discovery Ads playing a key role. Discovery ads reach up to 3 billion users across Google properties.

This article discusses how they work, their significance, and the challenges they face.

What are Google Discovery Ads?

Google Discovery Ads are a fully immersive, visually compelling ad format that enables advertisers to target users within three of Google’s most-used platforms:

Google Discover feed, YouTube, and Gmail. These ads are customized based on the user’s interests and read by Google AI,

which operates on search data, app use activity, and browsing patterns.

Key features of Google Discovery Ads include:

1. Visually rich creatives: The ad is primarily done through superior-quality videos or images, which can be swiped as a carousel where numerous brands or products are presented.

2. Advanced audience targeting: Options such as affinity audience, in-market audience, or custom segments enable advertisers to target particular users.

3. Expansive reach: Discovery Ads offer comprehensive visibility to over 3 billion monthly active users across Google’s ecosystem.

Effective strategies for Google Discovery Ads in 2025

There are five practical methods to maximize the return on investment (ROI) of your Google Discovery Ads campaigns:

1. Invest in high-quality visuals

The effectiveness of Discovery Ads depends on engaging visuals. To connect with your audience, present your products or brand narrative using a high-resolution image or a short, engaging video.

Tip: Use carousel ads to highlight several items or features, and ensure that the images fit your brand aesthetic.

2. Leverage precise audience targeting

Google’s targeting options, such as affinity, in-market, and lookalike audiences, can help the advertiser reach users with a high purchase probability.

Your reach can also be fine-tuned by adding these to custom intent audiences. According to Google, advertisers who treat their audience with first-class creatives achieve 16% more conversions when combining Discovery Ads with a Display or Video campaign.

Tip: Employ A/B testing, optimizing which audience segments perform best, and targeting accordingly using performance data.

3. Optimize for mobile experiences

Mobile devices account for 61.9% of all Google Ads clicks, so optimizing them is essential.

Ensure that your landing pages load quickly, have a clear call-to-action (CTA), and are easy to navigate on mobile devices.

Tip: Use Google Web to App Connect to increase the number of app installs directly with Discovery Ads and optimize mobile conversion.

4. Utilize AI-powered bidding

Google’s Smart Bidding strategies, Target CPA, and Maximize Conversions utilize AI to maximize the delivery of ads in real-time.

According to research conducted in 2024, with the increased automation, the median cost per acquisition (CPA) was lowered by 60% for advertisers who used optimized targeting.

Tip: Make sure your campaign’s budget is at least 15x the desired CPA so Google AI can optimize Google Ads.

5. Track and analyze performance

Use conversion tracking to monitor essential activities such as purchases, memberships, or visits.

As the campaigns shift to demand gen in 2025, product-level reporting can reveal in-depth information about which products generate the most engagement.

Tip: Connect Google Analytics 4 to measure your performance across different channels and optimize your strategy using data.

Challenges of Google Discovery Ads

Although Google Discovery Ads are extremely promising, several challenges might be faced by advertisers and thus affect the success of their campaigns:

1. Ad approval delays: Ads flagged as eligible (limited) can be delayed in getting their campaigns launched due to factors such as

implied interactivity or non-adherence to advertising policies as set by Google.

2. Budget limitations: Google AI will need sufficient budget to optimize ad delivery to its best capacity; otherwise, it will perform

poorly. Low budgets limit the algorithm’s ability to test and optimize audience targeting.

3. Creative fatigue: With time, users may get used to seeing the same ad creatives, and hence, engagement and click-through may

drop. This is especially true for viewers who have repeatedly seen the same messages or pictures.

4. Complex targeting setup: Google’s advanced targeting options, including in-market or affinity audiences, may overwhelm new

advertisers and result in poorly optimized campaigns.

5. Performance measurement: Without adequate conversion tracking or analytics integration, it can be quite tough to objectively

gauge the actual ROI of Discovery Ads, so it may prove difficult to justify ad expenditures.

Overcoming common challenges

Here are some solutions to the challenges mentioned above to make the campaign successful:

1. Ad approval issues: Attention to Google’s advertising policies and create ads without problems,

such as implied interactivity. Make sure that all creatives adhere to the guidelines to hasten approval.

2. Budget constraints: Google suggests that target CPA bidding should use budgets at least 15 times the target CPA,

to gather sufficient data for optimization.

3. Creative fatigue: Refreshing the ad creative by regularly adding a new headline, image, or video to keep users interested.

Plan creative changes once every 4-6 weeks to avoid burnout.

4. Set up intricate targeting: Begin with a more general group of audiences and narrow them down as you collect performance

data. Google can use the audience insights to determine high-performing segments.

5. Performance measurement: To accurately measure ROI, use conversion tracking and incorporate Google Analytics 4 to track

vital metrics such as purchases, sign-ups, or site visits.
