What are digital display ads?
A digital display ad is a visually-based paid advertisement shown across websites, mobile apps, and social media platforms. Unlike text-only ads, display ads combine images, colour, motion, or interactivity to capture attention. They’re the ads you see in a news article sidebar, between Instagram posts, or in a YouTube pre-roll. For a solid digital advertising overview, it helps to understand that display is one of the broadest and most flexible channels available.
The core formats you’ll encounter include:
- Banner ads: Static or animated image ads, usually in standard sizes (leaderboard, rectangle, skyscraper)
- Rich media ads: Interactive ads with expandable panels, video, or animated elements that respond to user behaviour
- Video ads: Short clips that play before, during, or alongside content on sites and apps
- Native ads: Ads styled to match the look and feel of the surrounding content, making them less disruptive
- Interactive ads: Ads that invite user participation, such as a mini-quiz or product selector built into the ad itself
The most important distinction between display and search ads is intent. Search ads are “pull” advertising. They appear when someone actively types a query into Google or Bing. Display ads are “push” advertising. They reach users based on who they are and what they’ve done online, not just what they’re searching for right now. This means display is particularly powerful for building brand awareness and re-engaging people who’ve already visited your website.
Display ads are also highly measurable. Every impression (how many times the ad is shown), click, and conversion (a sale, a form submission, a call) can be tracked. Because types of digital ads vary so widely, the format you choose will shape everything from your creative design to your measurement approach. Following display ads best practices such as using high-quality visuals and clear calls-to-action is the baseline for any effective campaign.
How do digital display ads work?
Understanding the mechanics helps you make smarter decisions about where your budget goes. At a high level, display ads are delivered through programmatic advertising platforms. These are automated systems that buy and sell ad space in real time, a process called real-time bidding (RTB). When someone loads a webpage, an auction happens in milliseconds. Advertisers bid for the chance to show their ad to that specific user, and the winning ad appears instantly.
Targeting is where display advertising becomes genuinely powerful. The four main targeting methods are:
- Geographic targeting: Show ads only to users in a specific city, region, or postcode
- Demographic targeting: Reach people based on age, gender, household income, or parental status
- Behavioural targeting: Target users based on their browsing history, purchase behaviour, and online interests
- Contextual targeting: Place ads on websites whose content matches your product or service category
Here’s a simplified view of the key metrics you should track:
| Metric | What it measures | Why it matters |
|---|---|---|
| Impressions | Times your ad was shown | Reach and visibility |
| Clicks | Times users clicked | Direct engagement |
| CTR (click-through rate) | Clicks divided by impressions | Creative effectiveness |
| Conversions | Desired actions taken | Campaign ROI |
| Viewability | % of ad actually seen on screen | True exposure quality |
A typical user journey looks like this: a potential customer browses a cooking blog, sees your kitchen product ad (impression), clicks through to your website (click), and purchases online (conversion). Every step is recorded. Focusing on improving ad performance means watching all of these numbers together, not just clicks. And because mobile outperforms desktop by 33-68% in engagement, making sure your ads are mobile-ready is non-negotiable for best practices for display ads.
Types and formats of digital display ads
Choosing the right format is just as important as choosing the right audience. Each format has its strengths, and matching format to goal will save you money and improve your results.
| Format | Best for | Strength | Limitation |
|---|---|---|---|
| Banner ads | Brand awareness, retargeting | Widely supported, affordable | Lower engagement rates |
| Native ads | Content marketing, awareness | High trust, low disruption | Slower to produce |
| Video ads | Storytelling, brand lift | High attention and recall | Higher production cost |
| Rich media | Product showcases, demos | Interactive, memorable | Requires more technical effort |
| Interactive ads | Lead generation, engagement | Participatory, data-rich | Complex to build |
For businesses just starting out, banner ads and native formats are usually the smartest entry point. They’re cost-effective, straightforward to produce, and supported across almost every publisher network. You can explore display ad formats explained to get a deeper breakdown specific to each type.
Here’s a quick guide to matching format to goal:
- Brand awareness: Native ads, video ads
- Retargeting past website visitors: Banner ads, rich media
- Direct response (sales, sign-ups): Interactive ads, banner ads with strong CTAs
- Product launches: Video ads, rich media
Video ads, while more expensive to produce, deliver some of the highest recall rates in digital advertising. If your business tells a strong story, video is worth the investment. For social-first campaigns, guide to digital ad types shows how the same message can be adapted across Facebook, Instagram, and YouTube with format-specific variations.
Pro Tip: Before committing to one format, test two or three with a small budget. Real audience data will always tell you more than assumptions about what your customers prefer.
Best practices for effective digital display ads
Knowing the ad types is useful, but strong results come from following proven industry best practices. The gap between a display campaign that drains budget and one that delivers real ROI often comes down to a handful of decisions made before the campaign launches.
Start with your creative. High-quality visuals are not optional. Blurry images, cluttered layouts, and weak calls-to-action (CTAs) are the fastest way to waste ad spend. Your CTA should be specific and action-oriented: “Book a free consult” beats “Learn more” almost every time. Follow banner ad optimisation strategies to ensure your creative is built for performance from the start.
Key best practices to implement from day one:
- Prioritise mobile: Mobile ads outperform desktop by 33 to 68%, so always design mobile-first and test on smaller screens
- A/B test everything: Run two versions of each ad with one variable changed at a time (image, headline, CTA) to find what performs better. See optimising ad creatives for a practical testing framework
- Measure viewability, not just impressions: An ad can be “served” but never actually seen. Viewability tells you how often your ad appeared in a user’s actual viewport
- Use retargeting: Showing ads to people who’ve already visited your site dramatically improves conversion rates compared to cold audiences
- Integrate with other channels: Display works best as part of a broader strategy. Combining display with search, social, and email creates multiple touchpoints. Targeting strategies for ads explains how to coordinate across channels effectively
“Focus on viewability and attention over raw impression counts. An impression that nobody sees has zero value to your business.”
Avoid these common pitfalls: targeting audiences that are far too broad, running the same creative for months without refreshing it, and failing to connect your ad data to actual business outcomes. For a structured checklist, display ad best practices is a solid reference point.
Our perspective: How small businesses can unlock the real power of display ads
Here’s something most guides won’t tell you: small businesses often have a genuine advantage in display advertising over large competitors. Big brands move slowly. Approvals take weeks. Creative refresh cycles drag on for months. As a smaller operation, you can test a new ad concept today and have real data by the end of the week.
The businesses we see getting the best returns aren’t necessarily spending the most. They’re spending smarter. They start with tight geographic targeting to reduce waste, test two or three creatives simultaneously, and scale only the winners. They treat their ad account like a living experiment, not a set-and-forget machine.
Display advertising rewards patience and curiosity. The first campaign rarely performs best. It’s the second and third, refined by real data, that start to generate consistent returns. Understanding why invest in digital ads is the mindset shift that separates businesses that grow with display from those that give up after one attempt. Budget matters far less than an experimental approach and honest measurement.

Frequently asked questions
How are digital display ads different from search ads?
Display ads push your message to relevant audiences visually based on who they are and what they’ve browsed, while search ads appear when users actively search for specific keywords. Display is ideal for awareness and retargeting, whereas search captures existing demand.
Which digital display ad format works best for small businesses?
Banners and native ads are usually the simplest and most scalable starting points, but the best format depends on your target audience, budget, and campaign goals. Testing two formats with a small spend is always the safest approach.
How can you track the effectiveness of a display ad campaign?
Track impressions, clicks, conversions, and viewability together to get an accurate picture of campaign performance. Relying on just one metric, such as impressions, can be misleading because an ad served is not always an ad seen.
Do mobile digital display ads really perform better than desktop?
Yes. Mobile display ads typically deliver 33 to 68% higher engagement than desktop equivalents, which is why designing mobile-first is now an industry standard rather than an optional extra.
