Crafting compelling ad creatives isn’t just about flashy visuals; it’s about understanding the intricate dance between psychology, data, and platform mechanics. For marketing professionals and students, we publish how-to guides on ad design principles that go beyond surface-level advice. Today, I’m going to walk you through setting up a high-performing Google Ads Discovery campaign in 2026, a format I firmly believe is often overlooked but delivers exceptional results when executed correctly. Ready to transform your reach?
Key Takeaways
- Google Ads Discovery campaigns leverage Google’s extensive feed-based properties (YouTube Home/Watch Next, Gmail, Discover) to reach users with visually rich ads.
- Successful Discovery campaigns require a minimum of 5 images (including at least 1 landscape and 1 square), 5 headlines, and 5 descriptions to allow Google’s AI sufficient creative assets for optimization.
- Audience targeting in Discovery is paramount; focus on custom segments, in-market audiences, and remarketing lists over broad demographic targeting for initial campaign setup.
- Bid strategy should start with “Maximize Conversions” with a target CPA, transitioning to target ROAS once sufficient conversion data is accumulated.
- Regularly review the “Asset Report” (found under “Campaigns” > “Ads & assets”) to identify underperforming creative elements and replace them promptly.
Step 1: Campaign Creation and Goal Setting – The Foundation
This is where we lay the groundwork. Don’t rush this part. A poorly defined goal or campaign type will hamstring your efforts before you even start.
1.1 Navigating to Campaign Setup
- Log into your Google Ads account.
- In the left-hand navigation panel, click Campaigns.
- Click the large blue + New Campaign button.
- You’ll be presented with a choice of campaign goals. For Discovery campaigns, I always start with Sales, Leads, or Website traffic. While you can choose “Create a campaign without a goal’s guidance,” I find Google’s goal-based structure helps align settings from the get-go. For this tutorial, let’s select Leads.
- Under “Select a campaign type,” choose Discovery. It’s usually the last option, easily identifiable by its distinct icon.
- Confirm your conversion goals. Google will pre-populate this based on your account settings. Make sure only the relevant conversion actions for lead generation (e.g., “Form Submission,” “Contact Us”) are selected. If you’re unsure, you can adjust these later under Tools and Settings > Measurement > Conversions.
- Click Continue.
Pro Tip: Don’t just accept Google’s default conversion actions. I’ve seen countless accounts tracking everything from “page views” as conversions, which completely skews optimization. Be precise. If you want leads, track lead forms. If you want sales, track purchases. Simple, right?
Common Mistake: Selecting “Brand awareness and reach” for a Discovery campaign. While Discovery does offer broad reach, its strength lies in driving action. If you’re purely after awareness, you’re better off with a Video or Display campaign, where different metrics and bidding strategies apply.
Expected Outcome: You’ll be on the “Select campaign settings” page, ready to name your campaign and choose geographic targets.
Step 2: Campaign Settings – Defining Your Reach
Here, we tell Google who, where, and when to show our ads. This is critical for controlling costs and maximizing relevance.
2.1 Naming and Location Targeting
- Campaign name: Choose something descriptive. I typically use a format like “DISC – [Product/Service] – [Audience] – [Geo] – [Date]” (e.g., “DISC – SaaS Demo – B2B Marketers – US – 2026-03”).
- Locations: Click Enter another location. I highly recommend targeting specific areas rather than entire countries if your business has a regional focus. For example, if you’re a solar installer based in Atlanta, Georgia, you might target “Fulton County, GA” and “DeKalb County, GA” rather than the whole state. You can also exclude locations, which is just as important. I once had a client, a local bakery in Decatur, GA, accidentally targeting “Georgia, US” and burning through budget showing ads in Georgia, Russia. Don’t make that mistake!
- Languages: Set this to the language of your ad copy and landing page. Defaulting to “English” is usually fine for most US campaigns.
2.2 Bidding and Budget – Your Financial Levers
- Bidding: Under “What do you want to focus on?”, select Conversions. Then, check the box for Set a target cost per action (optional). I strongly advise setting a target CPA from the outset. If your average lead acquisition cost is $50 from other channels, start with $60-70 here to give the system room to learn. My experience shows that Google’s AI learns much faster with a target CPA than with pure “Maximize Conversions” initially.
- Budget: Enter your Daily budget. Remember, this is a daily average. Google might spend up to twice your daily budget on any given day but will balance it out over the month. For a new Discovery campaign, I recommend starting with at least $30-50/day to give the algorithm enough data to work with. Anything less and you’re essentially starving the machine.
Pro Tip: Don’t change your bidding strategy or target CPA too frequently, especially in the first 2-3 weeks. Google Ads needs time – at least 50 conversions per month – to optimize effectively. Fiddling too much during the learning phase is a surefire way to confuse the algorithm and waste budget.
Common Mistake: Not setting a target CPA. While “Maximize Conversions” sounds appealing, without a cost constraint, Google might drive conversions at an unsustainable price point, especially if your conversion volume is low initially.
Expected Outcome: You’ll have a campaign name, targeted locations, a language, a defined bidding strategy with a target CPA, and a daily budget. Now, onto the ad group!
Step 3: Ad Group and Audience Targeting – Finding Your People
This is arguably the most critical step for Discovery campaigns. Unlike Search, where intent is explicit, Discovery relies heavily on intelligent audience segmentation.
3.1 Ad Group Naming and Audience Selection
- Ad group name: Again, be descriptive. “AG – [Audience Type]” (e.g., “AG – Custom Intent – Digital Marketers”).
- Audiences: This is where the magic happens. Click Add an audience.
- Custom segments: These are gold. Instead of relying on broad interests, create a custom segment based on “People who searched for any of these terms on Google” (e.g., “best marketing automation software,” “CRM comparison,” “lead generation strategies”) or “People who browse types of websites” (e.g., competitor websites, industry blogs). I often create custom segments based on competitor URLs – it’s a powerful way to siphon off their audience.
- Your data segments (Remarketing): Essential! Upload your customer lists (e.g., email subscribers, past purchasers) and create remarketing lists for website visitors. Targeting people who already know your brand or have shown interest is always a high-ROI play.
- In-market segments: Explore these carefully. Google identifies users actively researching products or services. For a B2B SaaS, I might look for “Business Software,” “Marketing Services,” or “CRM Solutions.”
- Life events & Detailed demographics: Use these sparingly and only if highly relevant. For example, “Starting a new business” could be relevant for some B2B services.
- Exclusions: Don’t forget to exclude irrelevant audiences. For instance, if you’re selling a premium product, you might exclude lower-income demographics if your data suggests they don’t convert.
Pro Tip: Start with 1-3 highly relevant audience segments per ad group. Don’t throw everything in at once. This allows you to analyze performance more effectively. If you combine a remarketing list with a broad in-market audience, and one performs terribly, you won’t know which one is the culprit.
Common Mistake: Over-relying on “Interest & detailed demographics.” While they can be useful, they are often too broad for Discovery campaigns, leading to wasted spend. Custom segments and your own data are far more potent.
Expected Outcome: Your ad group is named, and you have at least one well-defined audience segment applied. Now, the creative part!
Step 4: Ad Creation – The Visual Storytelling
Discovery ads are inherently visual. Your images and headlines need to grab attention in a feed-based environment.
4.1 Crafting Your Discovery Ad
- Final URL: This is your landing page. Make sure it’s mobile-friendly, loads quickly, and directly relates to your ad copy. I always use a unique UTM-tagged URL for tracking purposes.
- Images: This is where many campaigns fall short. You need a MINIMUM of five images, but I recommend providing as many as Google allows (up to 20).
- Aspect Ratios: You need at least one Landscape (1.91:1) and one Square (1:1). Upload multiple variations for each.
- Quality: High-resolution, professional images are non-negotiable. Avoid stock photos that look generic. Show your product in use, happy customers, or a compelling visual representation of your service.
- Text Overlay: Keep it minimal. Google’s AI often prefers images with little to no text.
- Logos: Upload at least one square (1:1) and one landscape (4:1) version of your logo.
- Videos (Optional but Recommended): If you have high-quality short video assets (under 60 seconds), upload them! Discovery campaigns can serve video ads on YouTube’s home feed, which is incredibly powerful.
- Headlines (5 minimum): Write compelling, benefit-driven headlines (up to 40 characters). Aim for variety. Some should highlight a problem you solve, others a unique benefit, and some a strong call to action.
- Example: “Boost Your Lead Quality,” “CRM That Works For You,” “Free Demo: See Our Platform,” “Stop Wasting Ad Spend,” “Get More Qualified Leads Today.”
- Long Headlines (5 minimum): These are slightly longer (up to 90 characters) and provide more context. Use them to expand on your main headlines.
- Descriptions (5 minimum): These are your body copy (up to 90 characters). Use this space to elaborate on your offer, highlight key features, and reinforce your call to action.
- Business Name: Your brand name.
- Call to action: Choose from the dropdown. “Learn More,” “Get Quote,” “Apply Now,” “Shop Now” are common. Pick the one that best matches your landing page’s primary action.
Pro Tip: Don’t be afraid to test radically different creative angles. A/B testing images and headlines is crucial. What you think will work often doesn’t, and vice-versa. I’ve had campaigns where a simple, almost bland image outperformed a professionally shot, high-concept one by 3x. The data tells the story.
Common Mistake: Reusing Display ad creatives verbatim. Discovery is a different beast. It’s more about native-feeling content consumption. Images need to blend in, not scream “ad.”
Expected Outcome: Your Discovery ad is complete, with a variety of images, headlines, and descriptions, and you’re ready to launch.
Step 5: Review and Launch – The Final Check
Before hitting that launch button, take a moment to review everything. A small error here can lead to significant wasted spend.
5.1 Final Checks
- Review all campaign settings: budget, bidding, locations, languages.
- Double-check your audience targeting. Are there any unintended exclusions or inclusions?
- Scrutinize your ads: Are all images uploaded correctly? Are headlines and descriptions grammatically correct and compelling? Is your final URL accurate and working?
- Ensure your conversion tracking is fully operational. This is non-negotiable. Without accurate conversion data, Google cannot optimize your campaign. I use Google Analytics 4 conversions imported into Google Ads, along with Google Ads’ own conversion tag for redundancy.
Editorial Aside: Seriously, if your conversion tracking isn’t perfect, pause everything and fix it. It’s like driving a car without a speedometer – you have no idea how fast you’re going or if you’re even moving in the right direction. This is where most campaigns fail, not because of a bad ad, but because the measurement is broken.
Expected Outcome: Your campaign is launched and begins serving ads. Now, the real work of monitoring and optimization begins!
Ongoing Optimization – The Journey, Not the Destination
Launching is just the beginning. Effective Discovery campaigns require continuous monitoring and refinement.
Monitor Performance and Adjust
Regularly check your Asset Report (under “Campaigns” > “Ads & assets”) to see which images, headlines, and descriptions are performing best. Replace “Low” performing assets with new variations. Look at your audience segments – which ones are driving the most conversions at the lowest CPA? Double down on those, and consider pausing underperforming ones. My firm, for instance, saw a 45% improvement in CPA on a client’s Discovery campaign within 3 months simply by consistently rotating out low-performing creative assets and refining audience segments based on the Asset Report data. According to an IAB report, digital ad spending continues to grow, emphasizing the need for efficient campaign management.
Google Ads Discovery campaigns, when set up meticulously and optimized consistently, offer a powerful channel to connect with potential customers who are open to discovering new products and services. Focus on compelling visuals, precise audience targeting, and robust conversion tracking, and you’ll unlock a significant growth opportunity for your business.

What is the minimum recommended daily budget for a Google Ads Discovery campaign?
I recommend a minimum daily budget of $30-50 for a new Discovery campaign. This provides enough data for Google’s machine learning algorithms to effectively learn and optimize your campaign for conversions. Anything less risks starving the campaign of data.
How many images should I upload for a Discovery ad?
You need a minimum of 5 images, including at least one landscape (1.91:1) and one square (1:1). However, I strongly advise uploading as many high-quality, diverse images as Google allows (up to 20) to give the system more creative options to test and optimize.
What are the most effective audience targeting options for Discovery campaigns?
The most effective audience options are typically custom segments (based on search terms or website visits), your own data segments (remarketing lists), and highly relevant in-market audiences. Avoid overly broad interest-based targeting initially.
How often should I check my Discovery campaign’s performance?
You should review your campaign’s performance, particularly the “Asset Report,” at least once a week. In the initial learning phase (first 2-3 weeks), checking every 2-3 days can be beneficial, but avoid making drastic changes too frequently.
Can I use videos in Google Ads Discovery campaigns?
Yes, you can! While optional, I highly recommend uploading high-quality, short video assets (under 60 seconds) if you have them. Discovery campaigns can serve these video ads on YouTube’s home and watch next feeds, significantly expanding your creative reach.
