Editorial Team Sarah, the marketing director for “GreenThumb Gardens,” an online plant nursery, had hit a wall. She was staring at her Google Ads dashboard, and the familiar frustration was setting in. While their search campaigns were doing okay, growth was flat. She knew their customers, mostly new homeowners and city dwellers between 25 and 45, were all over visual platforms, but GreenThumb’s ad strategy was still stuck in a text-heavy rut. How could they get noticed with eye-catching visuals on platforms like Google Discovery Ads, where images are everything?
Key Takeaways
- You have to prioritize high-quality, aspirational images and short, punchy videos for Google Discovery Ads. They’re what grab attention instantly in a busy feed.
- Create different sets of creative for your audience segments. You need to be testing everything from color palettes and which products you feature to the kind of lifestyle you’re showing.
- Set up a strict A/B testing plan for all your visuals. Keep a close eye on metrics like click-through rate (CTR) and conversion rate to figure out what’s actually working.
- For the first three months of a new Discovery campaign, plan on dedicating at least 60% of your budget to creating and testing visual assets.
- Work with user-generated content (UGC) and influencers. It’s the best way to get authentic, diverse visuals that people actually trust.
The Visual Imperative: Why Discovery Ads Demand a New Approach
Sarah’s intuition about needing better visuals was right on the money, and the data backs it up. An eMarketer report from 2025 on digital ad trends showed that people are 3.5 times more likely to engage with visual content than with text-only ads in their social and discovery feeds. This is especially true for Google Discovery, which puts your ads right into people’s YouTube, Gmail, and Google Discover feeds based on their interests. On these platforms, your ad is in a direct battle with engaging articles, emails from friends, and the latest viral video. A good visual is the primary hook that pulls people in.
GreenThumb Gardens had plenty of products, but their ad creative was mostly just photos of plants on plain white backgrounds. “These look like catalog pages, not inspiration,” Sarah said in a team meeting. “We need to show the dream, not just the plant.” They had to get away from static, boring product shots and create something that made people feel an immediate, aspirational desire. For Discovery Ads, the image does all the work, it’s your headline and your call to action all rolled into one.
Crafting a Visual-First Content Strategy: GreenThumb’s Transformation
Sarah decided to completely rethink GreenThumb’s Google Discovery Ads. Her first move was to put real money into professional photography and video that put their plants inside aspirational homes. So instead of a lonely fern on a table, they shot it in a beautiful, sun-drenched living room with books and a cozy blanket. Instead of a basic succulent close-up, they created a shot of a gorgeous succulent arrangement on a minimalist balcony with a city view.
She brought in a local lifestyle photographer who got the exact vibe GreenThumb was going for: calm, natural, and elegant without being intimidating. They built their visual strategy around three main themes: “Urban Jungle Oasis” for people in apartments, “Beginner Gardener’s Bliss” for newcomers, and “Pet-Friendly Plants” for anyone with animals. Each of these themes got its own set of images and quick 15-second video clips showing things like watering, repotting, or just a plant adding some life to a space.
Beyond the Static Image: The Power of Short-Form Video
Good images were a start, but Sarah knew video was dominating. She’d seen a 2024 IAB report on digital video that pointed out how short-form video ads (under 30 seconds) get much higher completion rates and brand recall on discovery-style platforms. For GreenThumb, this meant producing fast, visually dense videos. One of their most successful ones was a time-lapse of a seed sprouting into a small plant, which ended with the line: “Grow Your Own Joy.” Another was a quick montage of different plants, each with a tag like “Air Purifying” or “Low Maintenance.” These weren’t big, expensive productions. They were just tight, compelling clips made for a quick scroll.
“The whole point,” Sarah told her team, “is to tell a complete story in less than 15 seconds, and it has to work with the sound off. We want someone scrolling their Discover feed to just stop for a second and think, ‘I want my home to feel like that.'”

Audience Segmentation and Creative Iteration: The Data-Driven Approach
Once they had a solid library of visuals, GreenThumb launched the new Discovery campaigns. Instead of just throwing everything at the wall, Sarah took a surgical approach. She built custom intent audiences in Google Ads based on what people were searching for, like “indoor plant delivery” or “best houseplants for beginners.” She also targeted in-market audiences who were already looking at “home decor” and “gardening supplies.”
She then matched different creative sets to each segment. The “Urban Jungle Oasis” visuals were shown to audiences interested in modern design and apartment living, while the “Beginner Gardener’s Bliss” creative went to people searching for easy-care plants. This kind of specific targeting made sure the images would actually connect with what the viewer wanted.
A big lesson came from testing. “We assumed our minimalist look would appeal to everyone,” Sarah said. “But the data showed that our ‘Beginner Gardener’ segment converted way better with images that had clear care instructions or before-and-after shots of plant growth. For them, it wasn’t about looking cool. It was about feeling confident they wouldn’t kill the plant.” Using Google Ads’ A/B testing, they compared everything, hero images, video thumbnails, even small tweaks in color grading. They found that a specific deep forest green in their branding consistently beat lighter greens in click-through rates (CTR) by almost 15%. That’s the kind of insight you only get from rigorous testing.
“On Google, you bid on keywords, and Google surfaces your ad on those results pages. On ChatGPT, OpenAI matches ads to the conversation’s context, and visibility isn’t guaranteed.”
Integrating User-Generated Content and Influencer Collaborations
As the campaigns gained traction, Sarah knew they needed even more variety in their visuals. The professionally shot content was great for establishing the brand’s look, but user-generated content (UGC) is what builds real trust. They ran a social media contest asking customers to post photos of their GreenThumb plants with a specific hashtag, and then (with permission) they turned the best photos into Discovery Ads. These UGC ads, showing plants in real people’s homes, felt more authentic and relatable. A 2025 Nielsen consumer trust study backs this up, finding that ads with UGC are seen as 2.4 times more authentic than brand content.
They also started working with micro-influencers in the home decor and plant care space. These creators made unboxing videos and styled GreenThumb plants in their own homes, giving the company a constant supply of fresh, genuine visual content and expanding their reach to new, highly engaged audiences.
Measuring Success and Adapting: The Ongoing Process
Six months after launching their visual-first strategy for Google Discovery Ads, GreenThumb Gardens was seeing real results. Their overall conversion rate from Discovery campaigns shot up by 30%, and their return on ad spend (ROAS) jumped by 25%. Ad groups that used the new video creative had CTRs 20% higher than the old image-only campaigns.
Sarah’s team lived in the Google Ads asset reports, figuring out which image dimensions worked best on which placements (like square images for YouTube feeds and horizontal ones for Gmail). They also saw that creative showing people actually interacting with their plants, watering them, admiring a big Monstera, always outperformed sterile product shots. They were selling a lifestyle and a feeling of connection to nature.
Of course, this wasn’t easy. Producing high-quality visual content costs money upfront, and you can’t just create it once. “You can’t set it and forget it,” Sarah would tell her team. “Audiences get ad fatigue. We need a constant flow of new visuals every quarter and nonstop testing to keep things from going stale.” She started treating content creation as a regular line item in her marketing budget, with funds set aside for quarterly photo shoots and video edits.
GreenThumb’s turnaround demonstrates what it takes to win on Google Discovery Ads. You have to operate in a visual world. To get ahead, marketers have to think more like content creators, telling stories with images and videos that are good enough to stop someone from scrolling. Sarah’s work proved that by investing in visuals, segmenting audiences, and testing relentlessly, you can turn Discovery campaigns into a serious engine for growth.
If you’re trying to grow your business on Google’s discovery network, a strong visual-first content strategy isn’t just a nice-to-have. It’s the only way to get a meaningful connection and results you can actually measure. Learn more about how to avoid paid media mistakes that even the pros make.
What aspect ratios are best for Google Discovery Ads visuals?
For images, you should provide both 1.91:1 (field) and 1:1 (square) formats. For video, 16:9 (field) and 1:1 (square) are standard, but it’s a good idea to have vertical 9:16 versions for mobile-first placements, too. The key is to supply assets in multiple sizes so Google can optimize the display across YouTube, Gmail, and the Discover feed.
How frequently should I refresh my visual content for Discovery Ads?
You should plan on refreshing your main visual assets at least once a quarter to avoid creative fatigue. Your top-performing ads can obviously run longer, but you need to be constantly testing new images and videos to keep engagement up. For anything seasonal or related to a product launch, you’ll need to update even more often.
Can I use stock photography for Google Discovery Ads?
You can, but it’s risky. Custom, high-quality photos that show your actual products and reflect your brand’s style will almost always perform better. Stock photos often look generic and won’t create a real connection. If you absolutely have to use stock, be extremely picky and make sure it fits your brand’s aesthetic perfectly.
What key performance indicators (KPIs) should I track for Discovery Ads?
The most important KPIs for Discovery Ads are click-through rate (CTR), conversion rate, cost per conversion, and return on ad spend (ROAS). You should also keep an eye on total conversion volume. Tracking these numbers is the only way to know which visuals and targeting strategies are actually making you money.
How important is text in a visual-first Discovery Ad strategy?
The visuals do the heavy lifting, but the text still has a job to do. Your headlines and descriptions need to back up the visual by providing some context, a clear value proposition, and a strong call to action. Keep your headlines short and punchy, and make sure your descriptions are informative but brief, since they often get cut off on mobile.
