Display has a bad reputation. We still imagine it as these flashing banners that no one looks at, lost in the corner of the page. However, well conducted, a display campaign remains one of the most powerful levers for making a brand known and bringing back visitors who have not converted. The proof: a retargeting banner generates up to 10 times more clicks than a classic prospecting banner.

So what is the difference between a campaign that burns your budget and a campaign that pays off? In the method. Targeting, format, visual, landing page, management: every link counts.

In this guide, I explain how to create a successful display campaignstep by step, with the right settings, the 2026 benchmarks to know and the mistakes to avoid. Here we go.

What is a display campaign?

Display is visual advertising that is displayed on websites, applications and platforms: banners, visuals, videos, native formats. It is the heart of the profession and the expertise of a Display agency. Unlike paid referencing (SEA) which responds to an active search, display will search for the user where he iswhile reading an article or consulting an application.

The majority of these spaces are bought today in programmatic : automated, real-time auctions that place your ad in front of the right audience at the right time. This opens up enormous potential, but requires method to avoid wasting your budget. Here are the seven steps to follow.

Step 1: Set a clear goal

This is the most common initial mistake: launching a campaign without knowing what is expected of it. However, a notoriety objective and a sales objective are not managed in the same way at all.

  • Fame : you seek to be seen by as many people as possible. Key KPIs: impressions, reach, visibility rate.
  • Consideration : You want to generate interest and traffic. KPIs: clicks, CTR, qualified visits.
  • Performance : you are targeting concrete conversions (sales, leads). KPI: conversion rate, cost per acquisition, ROAS.

Set the goal before everything else. It will determine your targeting, your formats and how you judge success.

Step 2: Target the right audience

A perfect visual shown to the wrong person is of no use. Targeting is the real driver of display performance. You have several approaches, often complementary:

  • Retargeting : retarget visitors who already know your brand. It is by far the most profitable, with an average CTR around 0.7%compared to 0.1% to 0.4% for prospecting.
  • Targeting by audiences : target profiles according to their interests, their purchasing intention or first-party data (your customer base).
  • Contextual targeting : display your banners on pages whose content is linked to your offer. An approach that is making a comeback.
  • The lookalike : find new prospects who resemble your best customers.

A crucial point in 2026: the end of third-party cookies. With the deprecation of cookies in Chrome and the arrival of the Privacy Sandbox, targeting now relies on your first-party data and on the return of contextual targeting. Collecting and using your own data is no longer an option, it is the basis.

Step 3: Choose the right formats

Not all formats are equal. Certain sizes concentrate most of the inventory and performance. The essentials:

  • 300×250 (block): the most versatile format, with an average CTR of around 0.47%.
  • 728×90 (horizontal banner): ideal at the top of the page on desktop.
  • 160×600 (skyscraper): very visible on the side columns.
  • 320×50 (mobile banner): essential, as mobile accounts for the majority of impressions.

Beyond classic banners, think about advanced formats which better capture attention: the native advertising (integrated into the editorial content), the rich media and the outstream videowithout forgetting emerging channels like CTV (connected television) and the DOOH (programmatic outdoor display). Choose according to your objective and your audience.

Step 4: Take care of the visual

In display, you have less than a second to catch the eye. Your design must be clear:

  • A single message and immediately understandable.
  • A brand identifiable from the first glance.
  • A call-to-action clear (“Discover”, “Take advantage of the offer”).
  • A clean visual, without overload of text.

The big trend for 2026 is DCO (Dynamic Creative Optimization) : the AI ​​assembles variations of your banner in real time (title, image, CTA, color) based on the profile of each Internet user. Result, the right message is displayed in front of the right person, automatically. A powerful lever to boost CTR without multiplying creative work.

Step 5: Optimize the landing page

Too many campaigns send hard-won traffic to a generic landing page. Serious error. There continuity is essential: the landing page must repeat the message and visual of the banner, keep its promise and guide towards a single action.

A fast, clear page, designed for mobile and with a single conversion objective will make all the difference between a lost click and a won customer. The average conversion rate in e-commerce is around 1.5% to 2.5% : every point counts.

Step 6: Manage the budget and bids

Display remains a channel with a reasonable entry cost: the average CPC on the Google display network is around $0.63well below Search. You can buy at cost per thousand impressions (CPM) for awareness, or at CPC for performance.

It is here that the programmatic takes on its full meaning. Via a DSP (purchasing platform), you access the open exchange, but also private deals (PMP) on premium inventories. Managing auctions, audiences and frequency quickly becomes technical. For high-stakes campaigns, relying on a specialized agency allows you to avoid pitfalls and optimize each euro invested, where approximate management quickly wastes the budget.

Step 7: Continuously measure and optimize

A display campaign does not launch, it needs to be managed. Indicators to follow according to your objective:

  • The visibility rate (viewability) : an ad is “seen” when at least 50% of its pixels are displayed for 1 second. Aim for over 70%.
  • The CTR : to judge the grip (display reference ~0.46%).
  • Conversion rate and cost per acquisition : the true measure of profitability.
  • Frequency (frequency capping) : limit the number of exposures per person to avoid saturation.

Constantly test: visuals, audiences, formats. Cut what doesn’t work, strengthen what works. It’s continuous optimization that makes the difference over time.

Mistakes to avoid

Some classic pitfalls hamper performance. Keep them in mind:

  • The banner blindness : generic visuals that the eye ignores. The solution: strong creative and relevant context.
  • The absence of capping : beating up the same Internet user ends up annoying and damaging your image.
  • Ad fraud : non-human traffic and false clicks. Prioritize quality inventories and verification tools.
  • A simplistic measure : judging an awareness campaign based on CTR alone makes no sense. Align your KPIs with your objective.

Internally or with an agency?

Launching a basic display campaign is within everyone’s reach. But leveraging programmatic, orchestrating retargeting, managing first-party data and continuously optimizing requires time, tools and real expertise. That’s the whole point of calling on digital communication experts capable of managing your campaigns from A to Z and integrating them into a global acquisition strategy.

Conclusion

A successful display campaign is not about magic, but about rigor. A clear objective, precise targeting, suitable formats, eye-catching creative, a coherent landing page and continuous management: this is the recipe. The display is not dead, far from it. It reinvented itself with programmatic, AI and first-party data.
