If you've ever browsed a news site or a weather app and noticed a banner ad for a business you visited last week, you've already seen display advertising in action. It's one of the oldest forms of online advertising, and one of the most misunderstood.
This guide breaks down what display advertising actually is, what it's genuinely good at, what it's not built for, and how it fits alongside the other advertising you're probably already doing.
Why It Matters
Most local businesses only advertise on platforms where someone is actively searching or scrolling with intent, like Google or Facebook. Display advertising works differently: it puts your business quietly in front of people as they go about browsing the rest of the internet, reinforcing your name over and over.
That kind of repeated visibility matters more than it might seem. People rarely buy from a business the very first time they hear of it — display advertising helps make sure yours is a familiar name by the time they're ready.
How Display Advertising Works
What It Actually Is
Display ads are image or banner ads shown across a network of other websites and apps — not inside search results and not inside a social feed.
Because display ads appear across thousands of other sites, they can put your business in front of a local audience far more often than a search ad alone ever could.
Confusing display ads with search ads or social media ads — they run through separate systems with different goals.
A banner for a local roofing company appearing along the side of a news article is a classic display ad — the reader wasn't searching for a roofer at all.
What It's Best Used For
Display advertising shines at two things: retargeting people who already visited your website, and building broad awareness across your local area over time.
Staying visible to someone who already showed interest — or building general familiarity in your community — pays off later, even if it doesn't generate an instant response today.
Expecting display ads to generate the same immediate response as a search ad.
Someone who looked at a landscaping company's website last week but didn't book, and then keeps seeing that company's banner ad while reading the news, is far more likely to eventually reach out.
What It's Not Good For
Display advertising is not the right tool for capturing someone actively searching for your service right now — that's the job of search ads or Google Local Services Ads.
Search ads catch active intent ("plumber near me"); display ads reach people who aren't currently searching at all. Using the wrong tool for the wrong job leads to disappointing results and the wrong conclusions.
Cutting a search ads budget to fund display ads while hoping for the same volume of immediate leads.
A plumber with a burst pipe emergency is searching Google right now — display ads simply aren't built to catch that moment of urgent, active intent.
What Good Creative Looks Like
Keep the message simple, make sure text stays legible even at small banner sizes, and give the reader one clear call to action.
Display ads appear in small spaces across all kinds of screens. A cluttered or text-heavy design becomes unreadable and gets ignored.
Cramming a full paragraph of text into a banner that's only a couple hundred pixels tall.
A simple banner reading "Free Estimates — [Business Name]" with a clean logo and a "Get a Quote" button reads clearly even at a glance.
How It Fits Alongside Other Advertising
Display advertising works best as a supporting layer alongside search and social ads, not as a replacement for either one.
Search ads capture people actively looking; display ads keep your name in front of people who aren't ready yet. Together, they cover more of the customer's journey than either one alone.
Treating display advertising as a standalone strategy instead of one piece of a broader plan.
A dental practice running Google search ads for "dentist near me" alongside display ads that retarget past website visitors covers both the immediate searcher and the person still deciding.
If you're only going to run one type of display campaign, make it retargeting. It reaches people who already know your business, which usually makes it the most efficient use of a smaller budget.
Common Mistakes
Judging display ads by search-ad standards
Display advertising plays a different role. Measuring it purely on immediate calls or leads misses what it's actually good at.
Using cluttered, text-heavy banner designs
Display ads are small and often seen in passing — simple, legible creative performs far better than busy designs.
Running display ads with no other advertising in place
Display works best as a supporting layer. On its own, without a way to also capture active search intent, it leaves opportunity on the table.
Ignoring frequency
Showing the exact same banner to the same person dozens of times a week can start to feel intrusive rather than helpful.
