Plenty of business owners try display advertising once, see very few clicks and decide it doesn't work. Yet display is a channel that quietly takes more than a quarter of all U.S. internet ad revenue. Both things can be true. Display is very good at a few specific jobs and very poor at others, and most disappointing campaigns are display being asked to do the wrong job.
Display advertising means image, banner and responsive ads shown on websites and apps, as opposed to text ads on a search results page. In 2024 it earned $74.3 billion in the U.S., according to IAB, and Google's Display Network alone reaches over 90% of internet users worldwide. This page sets out the official figures, then explains when display works for a small or mid-sized business, when it wastes money and how to measure it honestly.

How much is spent on display?
According to IAB, display advertising brought in $74.3 billion in the U.S. in 2024, a rise of 12.4%. The $258.6 billion U.S. internet ad market gives display a 28.7% share, which puts it third behind search and social media.
The full-year 2024 revenue report from IAB counts what companies actually earned selling ads, so you're looking at real spending and not forecasts. Social media (36.7%) and video (19.2%) grew faster, though display still rose by double digits. Our digital advertising statistics has the full split by channel.
How far does display reach?
Very far. Google says its Display Network covers over 2 million websites, videos and apps where ads can run, and that those properties reach over 90% of the world's internet users, a figure it attributes to Comscore. Reach is what display does best, but most people in that audience aren't ready to buy at that moment.
You'll find both numbers in Google's Display Network definition. A reach this wide suits awareness and remarketing, but it also means untargeted display can use up a budget fast, because every banner shown to someone with no use for your service costs money and brings nothing back.
When does display work, and when does it waste money?
Display pays off for remarketing to recent visitors, for local awareness around an event or launch, for products that look good and for backing up a search campaign that's already converting. It usually wastes money when audiences are broad, app placements go unchecked, the service is an emergency one that people search for, or it's the only channel on a small budget.
| Works well | Usually wastes money |
|---|---|
| Remarketing to people who visited your site in the last 30 days | Broad interest audiences with no exclusions |
| Local awareness for a launch, event or seasonal offer | Running on every app and game placement |
| Visual products people browse and compare | Emergency services, where people search instead |
| Supporting a search campaign that already converts | As the only channel on a small budget |
| Reminding past customers about repeat services | Measuring success by click-through rate alone |
Two examples show the difference. A kitchen showroom with a new range launching wants people within 15 miles to hear about it before planning begins, so a month of local display and video ads, followed by remarketing to people who open the range page, makes sense. An emergency locksmith gets almost nothing from display, since no one plans a lockout and people search the moment it happens, so search and a strong Business Profile do the work. (Neither is a real client; both are illustrations.)
The main types of display ads
Small advertisers usually get by knowing four formats, and each one belongs at its own point in the customer journey.
- Responsive display ads. Hand the ad network your headlines, a few descriptions, some images and a logo, and it puts them together to suit each placement. This is the easiest way in, because one set of assets fills a huge number of different ad sizes.
- Uploaded image ads. These are banners you build yourself at set sizes, so you control the design completely, but covering enough placements takes extra effort.
- Video ads. Brief clips that play ahead of or next to other videos, and on partner sites. They're handy when you need to walk people through a service or demonstrate a product being used.
- Native-style ads. These ads are styled to blend in with the page around them, often as recommended articles. They can suit content promotion, and you still have to label them clearly as ads.
We'd start most small businesses with responsive display ads shown to a remarketing audience. They go live fast, the results are simple to read, and the people seeing them already know who you are.
Creative that works on small screens
Phones account for most display impressions, so start your design with a small banner in mind. Stick to a handful of rules and the results improve a lot:
- One message per ad. Pick one thing to say: a reason to visit, a product or an offer.
- Your name or logo visible at a glance. If all someone takes away is who the ad came from, the ad has still partly done what it's there for.
- Short, specific headlines. A line like "Kitchen range launch, 20 models in store" tells people more than "Transform your home today."
- Real photos where possible. Photos of your own work, your team or your premises usually do better than generic stock images.
- A clear next step. Examples are "See the range", "Book a visit" and "Get a quote." Pick the one that fits the page the ad leads to.
- Fresh creative every few months. Anyone who sees the same banner again and again stops noticing it.
Remarketing audience ideas
Display most often earns its keep through remarketing, since you're reaching people who've already shown some interest. These are practical audiences to build:
- Visited a service or product page but didn't enquire in the last 30 days.
- Started a quote or booking form but didn't finish it.
- Visited your pricing page in the last 14 days.
- Past customers whose next service is coming up again, for example an annual check or a seasonal visit, provided your customer data and the platform's rules permit it.
Exclude anyone who has converted recently, so you don't pay to show ads to someone who just bought from you. Match the message to the audience as well: a person who looked at one particular service will usually respond better to a reminder about it than to a general brand banner.
A display checklist for small businesses
- Start with remarketing. In the last 30 days, visitors to your contact, pricing or service pages make up your warmest audience.
- Review placements every week. Block apps and sites that deliver clicks but no engagement, because a small number of app placements swallow a lot of wasted display budget.
- Cap frequency. One person who sees the same banner twenty times a day gets annoyed, and you've spent money on it.
- Use proper sizes and clear text. Someone holding a phone should be able to read both your name and what you're offering.
- Send clicks to a matching page. An ad about a kitchen range should land the click on that range's page rather than the homepage.
- Measure what happens after the click. Check GA4 for engaged sessions and key events, and count the later converters who saw a display ad before converting.
How to measure display honestly
Don't use click-through rate as your headline number for display. Someone reading a news site who sees your banner wasn't looking for you, so few people click straight away, and that's normal. A better test is whether display traffic produces engaged visits and key events, whether many converters saw display first, and whether brand searches climb while the campaign runs.
By source and campaign in GA4, you can compare engaged sessions with key events, and if a placement sends hundreds of clicks yet nobody engages, cut it. Over a few months, check Search Console to see if people searching for your business by name go up while your display ads run. Often that's the clearest evidence awareness is working, even if few conversions come straight from display.
If you'd like display side by side with your other channels, set up a business analytics dashboard showing sessions and key events for each source.
What our own search data shows
Over 90 days, our site picked up 753 impressions in Google for the search phrase "display marketing agency" and 214 for "automotive display advertising". So businesses are plainly looking for help with display. We think display pays off most when it backs channels that already convert, rather than as a stand-alone bet.
Car dealers show where display can work well: buyers spend weeks comparing, and a showroom visit matters more to them than a form fill. Pairing display and video for a sales event with remarketing to shoppers who viewed particular models suits the way buyers really go about buying a car. You can read about that use case on our automotive display advertising page, and our display advertising service covers campaigns in other industries.
Figures you'll see elsewhere that we left out
You'll often see display stats pages lean on ad-blocking rates, banner blindness percentages and average click-through rates. Those averages blend every industry and format together, which hides huge differences, and plenty of the numbers trace back to old or vendor studies we couldn't verify. So we stuck with IAB's measured revenue and the network figures Google publishes.
Sources and method
Revenue figures come from the IAB Internet Advertising Revenue Report for full-year 2024, prepared with PwC. Network size and reach come from Google Ads Help. The Search Console figures are from greatinflux.com over 90 days to early November. All figures were checked on the source pages.
Frequently asked questions
How much is spent on display advertising in the US?
IAB reports U.S. display advertising revenue of $74.3 billion in 2024, up 12.4% on the previous year and equal to 28.7% of all internet ad revenue.
How many people does the Google Display Network reach?
Google says Display Network sites reach over 90% of internet users worldwide, citing Comscore. The network is a group of more than 2 million websites, videos and apps where ads can appear.
Is display advertising good for small businesses?
Display works best for remarketing to people who already visited your site, for local awareness around a launch or offer, and for visual products. It is a weak first channel for a service business with a small budget, where search ads usually convert better.
Why do display ads get low click-through rates?
Display ads interrupt people who are reading or watching something else, unlike search ads that answer a query. Judge display by reach, engaged visits and assisted conversions, not by click rate alone.
What should I measure in a display campaign?
Measure where your ads appear, the cost per thousand impressions, engaged visits and key events from those visits in GA4, and how many people who later converted saw a display ad first. Exclude placements that bring clicks with no engagement.
What is remarketing?
Remarketing shows ads to people who have already visited your website or used your app. Because they already know you, these audiences usually respond better than people who have never heard of you.
How much should a small business spend on display?
Start small and fixed, with a monthly cap you can afford to learn with, and only after search or another core channel already produces enquiries. Increase it only when you can see display contributing to leads or sales.
