When you’re running display advertising campaigns, the design of your ads can make or break your results. Even with perfect targeting and bidding strategies, a poorly designed display ad will fail to capture attention and drive conversions. Let me walk you through the top five mistakes that advertisers make when designing display ads, and more importantly, how to avoid them.
Mistake #1: Overcrowding Your Ad with Too Much Information
One of the most common mistakes in display ad design is trying to cram too much information into a small space. Your ad might be competing with dozens of other elements on a webpage, and users typically spend less than two seconds deciding whether to engage with an ad.
When you overload your display ad with text, multiple images, and competing calls-to-action, you create visual noise that overwhelms the viewer. This leads to lower click-through rates and wasted ad spend. Instead, focus on one primary message and one clear call-to-action.
Keep your text minimal – aim for no more than 10-15 words total. Use bullet points or short phrases rather than complete sentences. Remember that your ad should create curiosity and encourage users to click through to your landing page for more information.
Mistake #2: Using Poor Color Contrast and Hard-to-Read Fonts
Color choice and typography significantly impact how users perceive and interact with your display ads. Many advertisers make the mistake of using colors that blend into the background of websites or fonts that are difficult to read on various devices.
Research from the Nielsen Norman Group shows that users scan web pages in an F-pattern, and your ad needs to stand out quickly. Poor color contrast not only makes your ad harder to read but can also make it appear unprofessional or spammy.
Choose colors that create strong contrast between your text and background. Dark text on light backgrounds or light text on dark backgrounds typically work best. Avoid using similar colors for text and background, even if they’re different shades. For fonts, stick to clean, sans-serif typefaces that remain legible at smaller sizes. Test your ad designs across different devices and screen resolutions to ensure readability.
Mistake #3: Ignoring Mobile Optimization
With mobile devices accounting for over 50% of web traffic, designing display ads that don’t work well on mobile screens is a critical mistake. Many advertisers still create ads optimized only for desktop viewing, missing out on a massive portion of their potential audience.
Mobile users have different behaviors and expectations compared to desktop users. They’re often on-the-go, have shorter attention spans, and interact with content through touch rather than mouse clicks. Your display ads need to accommodate these differences.
Ensure your ad designs are responsive and look good on various screen sizes. Keep important elements like your call-to-action button large enough for easy tapping on mobile devices. Test your ads on actual mobile devices rather than relying solely on desktop previews. Consider the loading speed of your ads, as mobile users are particularly sensitive to slow-loading content.
Mistake #4: Weak or Missing Call-to-Action
A display ad without a clear, compelling call-to-action is like a salesperson who won’t ask for the sale. Many advertisers either forget to include a call-to-action altogether or make them too subtle to notice.
Your call-to-action should be the most prominent element in your ad design. It should tell users exactly what you want them to do – whether that’s “Shop Now,” “Learn More,” “Get Started,” or “Claim Your Free Trial.” The language should be action-oriented and create a sense of urgency or value.
Design your call-to-action button with contrasting colors that make it stand out from the rest of the ad. Use whitespace around the button to draw attention to it. Test different button sizes, colors, and text to find what works best for your audience. Remember that your call-to-action is often the deciding factor in whether someone clicks your ad or scrolls past it.
Mistake #5: Poor Brand Consistency
Many advertisers create display ads that don’t align with their overall brand identity, causing confusion and reducing trust with potential customers. When users see an ad that looks nothing like your website or other marketing materials, they may question its legitimacy.
Brand consistency builds recognition and trust over time. Your display ads should use your brand colors, fonts, logo, and overall visual style consistently. This doesn’t mean every ad needs to look identical, but there should be clear visual connections between your ads and your brand.
Create a brand style guide specifically for your display advertising that outlines acceptable color palettes, font choices, logo usage, and image styles. This ensures that everyone creating ads for your brand maintains consistency. Consider how your ads will look alongside your competitors’ ads and make sure yours stand out while still representing your brand accurately.
The Connection Between Ad Design and Bidding Strategy
Your display ad design directly impacts your bidding strategy and campaign performance. When you have well-designed ads with high click-through rates, you can often achieve better results with lower bids. This is because advertising platforms like Google Ads reward ads that engage users with better placement and lower costs.
For campaigns focused on brand awareness, you might want to explore CPM (cost-per-thousand impressions) bidding. Well-designed display ads that capture attention can be particularly effective with CPM strategies, as you’re paying for visibility rather than clicks. Check out our guide on when to use CPM instead of CPC for brand awareness to learn more about this approach.
Testing and Optimization Strategies
Creating effective display ads isn’t a one-time task – it requires ongoing testing and optimization. A/B testing different design elements can help you understand what resonates with your audience and drives better results.
Test one element at a time, such as different headlines, images, colors, or call-to-action buttons. Use the data from your tests to make informed decisions about your ad designs. Even small changes can lead to significant improvements in click-through rates and conversions.
Consider implementing dynamic creative optimization, which automatically adjusts your ad elements based on user behavior and preferences. This can help you deliver more personalized and effective ads to different audience segments.
Advanced Design Techniques for Better Results
Beyond avoiding the common mistakes, there are several advanced techniques you can use to make your display ads more effective. Animation and motion can capture attention more effectively than static images, but use them sparingly and purposefully.
Video display ads can be particularly powerful, but they need to be short and attention-grabbing. The first few seconds are crucial for capturing viewer interest. Consider using interactive elements that encourage user engagement, such as quizzes or product configurators.
Personalization is another powerful technique. Use dynamic content to show different messages or offers based on user demographics, behavior, or location. This can significantly improve relevance and conversion rates.
Measuring Design Success
To know if your display ad designs are working, you need to track the right metrics. Click-through rate is an obvious starting point, but also pay attention to conversion rate, cost per acquisition, and return on ad spend.
Use heat mapping tools to understand how users interact with your ads. This can reveal whether people are noticing your call-to-action buttons or getting distracted by other elements. Monitor your quality scores and ad relevance metrics to ensure your designs are contributing to overall campaign health.
Frequently Asked Questions (FAQ)
What size should my display ads be for optimal performance?
The most effective display ad sizes vary by platform and placement, but some consistently perform well across networks. The 300×250 medium rectangle and 728×90 leaderboard sizes are widely supported and tend to have good inventory. The 160×600 wide skyscraper works well for sidebar placements. Always create multiple sizes to maximize your reach across different ad placements.
How many words should I include in my display ad copy?
For most display ads, aim for 10-15 words maximum. This includes your headline, body copy, and any additional text. The goal is to communicate your core message quickly and encourage clicks. Remember that users are scanning quickly, so every word needs to earn its place in your ad.
Should I use stock photos or custom images in my display ads?
Custom images generally perform better than stock photos because they’re more authentic and unique to your brand. However, high-quality stock photos can work well if they’re relevant and not overused. Avoid the most popular stock images that users have seen repeatedly. The key is choosing images that support your message and resonate with your target audience.
How often should I update my display ad designs?
Plan to refresh your display ad designs every 2-3 months, or sooner if you notice declining performance. Ad fatigue can set in when users see the same designs repeatedly. Regular updates keep your ads fresh and can help maintain engagement rates. Monitor your performance metrics closely to identify when it’s time for a redesign.
What’s the ideal contrast ratio for display ad text?
For optimal readability, aim for a contrast ratio of at least 4.5:1 between text and background colors. This ensures that your text remains legible across different devices and for users with various visual abilities. Use online contrast checkers to verify your color combinations meet accessibility standards.
Conclusion
Creating effective display ads requires attention to detail and a deep understanding of user behavior and design principles. By avoiding these five common mistakes – overcrowding, poor color choices, ignoring mobile optimization, weak calls-to-action, and inconsistent branding – you can significantly improve your ad performance.
Remember that great display ad design is an ongoing process of testing, learning, and optimization. Start with these fundamentals, then continue refining your approach based on your specific audience and campaign goals. The investment you make in better ad design will pay dividends through improved engagement, lower costs, and better overall campaign results.
Focus on creating ads that not only look good but also drive meaningful business results. Your audience will appreciate the clarity and professionalism of well-designed ads, and you’ll see the difference in your campaign metrics.
