Every day, millions of display advertising impressions are bought and served across Canada. Yet a significant portion of that investment misses the mark, not because the format is inadequate, but because it is poorly executed. Low-quality inventory, generic creatives, overly broad targeting, superficial measurement: display advertising has a reputation problem it does not deserve.
Display is not in decline, it is evolving. And in a landscape where closed platforms like Google and Meta capture attention out of habit rather than relevance, knowing how to properly activate display advertising across the open web opens up possibilities that many advertisers have yet to explore.
This article covers the display channel from end to end: what it actually is, the formats available, how programmatic advertising has transformed media buying, the real benefits for your brand, and the mistakes to avoid.
What Is Display Advertising?
Display advertising refers to all visual ad formats served across websites, mobile applications, and digital environments whether static banners, animated creatives, or interactive formats.
It is one of the oldest forms of digital advertising, and also one of the most transformed by technology. Where display in the 2000s relied on direct buys and bilateral agreements between advertisers and publishers, today’s display inventory is largely purchased in an automated, real-time fashion through programmatic buying platforms.
Display, Search and Social: What Sets Them Apart?
These three concepts are often conflated, but display, search and social each serve a distinct purpose.
Search advertising (Google Ads, for example) targets audiences who are actively looking for something. It is a demand-capture channel: the user already has an intent, and the ad intercepts them at the right moment.
Social display advertising (Meta, LinkedIn, TikTok, etc.) inserts itself into a content feed. It leverages the behavioural and demographic data held by those platforms but within a closed environment fully controlled by the publisher.
Open web programmatic display, on the other hand, delivers your message across the entire open web and its applications: news outlets, niche publications, content platforms, mobile environments. What sets it apart from closed environments like Meta or Google Ads is access to independent editorial inventory that those platforms simply do not offer, with full transparency over where your ads actually run. It is particularly effective for building brand awareness, driving memorability, and maintaining a consistent brand presence throughout the customer journey.
The three channels often work best together within an omnichannel strategy. That said, display is frequently overlooked in strategies that lean too heavily on Meta and Google, at the expense of a diversification that would meaningfully strengthen overall impact.
Programmatic Display vs. Traditional Display
Historically, buying display advertising meant negotiating directly with each publisher. It was slow, time-intensive, and offered little flexibility.
Programmatic display changed that entirely. Ad inventory is now bought and sold in an automated fashion through technology platforms. The specialist defines the parameters, target audience, preferred environments, campaign objectives, and the platform optimises the purchase of each impression in real time.
The result: more precise targeting, more efficient delivery, and a depth of measurement that direct buys simply cannot match.
What Display Advertising Formats Are Available?
Display advertising is far more than a simple banner. It encompasses a wide range of formats, each with its own characteristics and use cases. Here is a complete overview.
Standard IAB Banners
Formats standardised by the Interactive Advertising Bureau (IAB) are the most widely used. The primary dimensions in North America are as follows:
- Leaderboard : 728 x 90 px
- Medium Rectangle : 300 x 250 px
- Half Page : 300 x 600 px
- Skyscraper : 160 x 600 px
- Billboard : 970 x 250 px
These formats appear on virtually every website. Their advantage: universal compatibility across all environments and buying platforms. Their limitation: in a low-quality open marketplace, they are easily overlooked.
| A note on real impression visibility |
| The IAB sets the viewability threshold at a minimum of 50% of the banner visible on screen for at least one second to be counted as a viewable impression. That is a floor, not a target. In Canada, the IAB’s 2025 benchmark sets 70% viewability as the minimum quality reference for display advertising. |
Rich Media and Interactive Formats
Rich media refers to enhanced ad formats: animations, embedded video, dynamic interactions, and click or hover-triggered expansions. A well-executed rich media format can drive significantly higher engagement rates than a static banner, provided it is relevant, does not disrupt the browsing experience, and is served in an environment suited to its format.
These formats are particularly well-suited to product launches, upper-funnel awareness campaigns, or any communication that benefits from a strong visual treatment.
Display Video (In-Banner and Outstream)
Display video is distinct from streaming video or connected TV advertising. It refers to video content embedded within display ad placements: in-banner (the video plays directly within the banner unit), or outstream (the video appears between blocks of editorial content and pauses as soon as it leaves the user’s field of view).
These formats combine the impact of video with the flexibility of programmatic display. They allow advertisers to reach audiences across the open web with video content, without relying on social platforms or streaming services.
Native Display
Native is a display format that blends visually into a site’s editorial content. It resembles a recommended article rather than a traditional banner, making it one of the least intrusive formats available. It typically generates stronger engagement and better memorability precisely because it integrates naturally into the reading experience.
It is a format worth considering for brands looking to promote in-depth content, support a brand awareness campaign, or reach an audience that is already in a content-receptive mindset.
Mobile Display
Mobile now accounts for the majority of time spent online. Mobile display formats include responsive banners, interstitials (full-screen ads served between two pieces of content), and formats integrated directly within applications.
Digital Out-of-Home Advertising (DOOH)
DOOH is digital out-of-home advertising: screens in streets, shopping centres, airports, and public transit. What is changing today is that a growing portion of this inventory can now be purchased programmatically, in the same way as a web banner.
This opens up meaningful opportunities for local and geo-targeted campaigns. It is now possible to deliver a message within a precise geographic area, at specific times of day, in quality environments, with the full flexibility of programmatic buying. Geographic targeting can go as far as a radius around a specific address, or leverage techniques such as geofencing for highly localised campaigns, a complementary tactic to display that is particularly effective for driving in-store traffic or supporting event-based activations.
This remains an underutilised format among many Quebec and Canadian advertisers, who often perceive it as technically complex when access is, in practice, far more straightforward than it appears.
How Does Programmatic Display Advertising Work?
Display Targeting Options
Targeting is where programmatic display truly sets itself apart from traditional media buying.
First-party and third-party data targeting: leveraging your own customer data, or qualified data from specialised providers such as Adsquare or Foursquare, available directly through DSPs.
Socio-demographic targeting: age, gender, income level, household composition. Useful for establishing a baseline audience.
Geographic targeting: province, city, postal code, or radius around a specific address. Essential for local brands or regional campaigns. Geofencing takes this further by defining highly precise virtual geographic zones (around a point of sale, a competitor location, or an event venue) to serve display banners to people who have been physically present in that area.
Behavioural targeting: based on browsing habits, interests, and past behaviour. Allows you to reach people who have demonstrated interest in a given category.
Contextual targeting: ads are served on pages whose content is aligned with your message.
Retargeting: reaching people who have already visited your website or engaged with your brand. This is often the tactic that delivers the strongest short-term return, as it targets an audience already familiar with your offer.
Open Marketplace vs. Curated Inventory: A Distinction That Matters
Not all display inventory is equal and this is arguably the most misunderstood reality in the industry. The effectiveness of a display campaign often comes down to inventory quality far more than impression volume.
The open marketplace provides access to an enormous volume of ad placements at typically low costs. But within that inventory, you will also find low-quality sites, MFA (Made For Advertising) environments that put your brand at risk, and non-negligible levels of ad fraud.
Curated inventory, on the other hand, brings together placements selected on the basis of editorial quality, real viewability, and brand safety. Quality Quebec and Canadian media, major national and international publishers, premium environments: this is where your brand has the most to gain.
What Are the Benefits of Display Advertising?
Display is one of the few formats capable of working across awareness, consideration, and conversion simultaneously. Here are its concrete advantages.
Broad yet targeted reach: Display reaches audiences across the entire open web, well beyond closed platforms. Combined with precise targeting, it allows you to connect with the right people in the right contexts.
Format flexibility: From simple banners to rich media, native, and DOOH, display adapts to a wide range of objectives and creative approaches.
Presence throughout the customer journey: Display is particularly effective for sustaining brand presence over time. A prospect who discovered your offer through a search campaign can encounter your brand again during their daily reading. That consistency builds memorability.
Detailed measurement: Impressions, viewability rates, post-view conversions, brand lift. Programmatic display offers a depth of measurement that far exceeds what traditional channels can provide.
Access to local media: For brands rooted in Quebec and Canada, programmatic display provides access to major Quebec and Canadian media inventory on far more favourable terms than direct buys. An underutilised lever for strengthening a brand’s local presence.
How to Integrate Display Into Your Advertising Strategy
Display for Brand Awareness
Brand awareness is display’s natural territory. When your objective is to build recognition, expand your audience, or position your brand within a specific space, display is one of the most effective formats available.
For an awareness campaign, the key metrics to track are reach, exposure frequency, and ideally a measure of ad memorability through a brand lift study. The goal is to be seen in the right environments, with enough frequency to make an impression, without saturating your audience.
Display and Retargeting
Display retargeting is one of the most directly measurable tactics available. If you have an audience that has visited your website, watched a video, or engaged with your content, display allows you to reach them again across the open web with a message tailored to their level of engagement.
That said, retargeting is not a set-and-forget tactic. Too high a frequency can cause irritation, and a creative not suited to a conversion context will miss its mark. Casting the net too wide, targeting all site visitors without segmentation, also dilutes effectiveness.
Solid display retargeting rests on precise audience segmentation, rigorous frequency management, and creatives built for conversion rather than awareness.
Programmatic Display for Quebec and Canadian Businesses
Today, a Quebec or Canadian small or mid-sized business can activate a programmatic display campaign across quality local media, with precise geographic targeting (region, city, neighbourhood), formats suited to their creative capabilities, and transparent measurement of results.
What sets this apart from a standard Google Display Network campaign: access to quality local Quebec, Canadian and international inventory, full transparency over where ads are served, and the ability to reach audiences in environments that Meta and Google Ads simply do not offer.
Common Display Advertising Mistakes (and How to Avoid Them)
1. Investing in open marketplace inventory without quality selection
Volume does not compensate for quality. A high number of impressions served across low-quality sites carries no real value for your brand and puts your reputation at risk. Environment selection should always come before volume negotiation.
2. Ignoring real impression visibility
A purchased impression is not a viewed impression. Without viewability tracking, you are investing in placements that may never have appeared within the user’s field of view. Incorporating viewability indicators from the planning stage is a sound foundation for any campaign.
Beyond viewability, attention metrics are gradually establishing themselves as a complementary standard. It is now possible to measure whether a user genuinely paid attention to an ad, not simply whether it was technically visible on screen. An indicator worth integrating into your campaigns if you are looking to push further on qualitative measurement.
3. Failing to manage frequency
Serving the same message to the same person too many times is one of the most common causes of inefficiency and audience irritation. Rigorous frequency management is a basic requirement of any serious display campaign.
4. Treating Display as a Standalone Channel
Display performs best when integrated into a broader strategy. A prospect exposed to both a display message and a CTV or audio message, for example, is likely to show a significantly higher conversion rate. Cross-channel consistency is a performance multiplier, not an afterthought.
5. Measuring Only Click-Through Rate
Click-through rate (CTR) is one of the least representative indicators of a display campaign’s actual impact. Display works primarily on memorability and brand awareness. Post-view conversions, brand lift, and incrementality are far more relevant measures of what display is genuinely accomplishing.
6.Failing to Refresh Creatives
An audience exposed to the same message too many times will eventually stop seeing it. This is creative fatigue: the brain automatically filters out what it recognises as familiar. Click-through rates drop, memorability erodes, and budget continues to be spent with diminishing returns.
The right approach is to test multiple messages, angles, and visuals within the same campaign. This allows you to identify what genuinely resonates with your audience and sustain attention over time. A display campaign running for several weeks without creative rotation loses a meaningful portion of its value after the first few exposures.
What NÜ Does Differently With Display
When we talk about a premium approach to digital advertising, we mean something specific: access to media environments selected for their editorial value, qualified audience, and ability to strengthen brand image, not simply for the lowest possible cost per click.
At NÜ, display advertising is a channel we activate as part of our programmatic campaigns. Here is what that means in practice.
Environment selection first
At NÜ, inventory is not chosen by default, it is selected against explicit criteria: editorial quality, brand safety, and real viewability. We start with quality Quebec and Canadian media, because that is where your brand has the most to gain. Not because it is the easiest or fastest option.
No compromise on brand safety
We apply strict protocols against ad fraud and MFA (Made-For-Advertising) environments. These sites are built to generate impressions with no real value for the advertiser. We exclude them systematically before we even begin optimising.
Targeting built around your reality
We do not start from a standard segment list. We start from your actual audience, your market, and your objectives, then build the targeting strategy from there, combining first-party data, third-party data, and contextual signals based on what is most relevant to your situation.
Measurement that goes beyond the click
Our display campaigns incorporate viewability indicators, post-view analysis, and where relevant, lift measurement to quantify the real impact on brand awareness or audience behaviour. These are not just numbers, they are actionable insights that inform your broader marketing decisions.
Full transparency, from launch to delivery
You have access to all campaign data: which sites, which formats, which results, which adjustments were made. If something is not performing, we tell you, we explain why, and we show you how we are correcting it. That is what it means to be a committed partner.
Conclusion
Display advertising remains one of the most powerful levers in digital advertising, provided it is activated with rigour. It is not a format to be improvised, nor is it one reserved for large brands with unlimited budgets.
What separates a display campaign that genuinely builds a brand from one that quietly consumes budget is the quality of the environments chosen, the precision of the targeting, the relevance of the creatives, and the depth of the analysis.

FAQ — Frequently Asked Questions About Display Advertising
What is display advertising in digital marketing?
Display advertising refers to visual ad formats served across the open web and mobile applications: banners, rich media, native, display video, and digital out-of-home (DOOH). It is distinguished from search advertising (which targets active intent) and social advertising (which operates within a closed environment) by its ability to reach audiences across the entire open web.
What is the difference between display and programmatic?
Display is an ad format. Programmatic is a buying method. Programmatic display refers to display inventory purchased in an automated, real-time fashion through technology platforms such as The Trade Desk, DV360, or StackAdapt. The majority of display inventory bought today is purchased programmatically.
Is display advertising effective for a small or mid-sized business?
Yes, provided it is activated with the right parameters. Programmatic technology has made access to local Quebec and Canadian inventory available to businesses of all sizes. The determining factor is not budget; it is the quality of the planning and the rigour of environment selection.
Which display advertising formats should I choose?
It depends on your objective. For awareness, high-visibility formats such as half-page, billboard, and rich media are well suited. For retargeting, a well-designed standard banner is often sufficient. For mobile audiences, screen-adapted formats are essential. The right answer always starts with the objective and the audience, not the format.
How do you measure the effectiveness of a display campaign?
The key metrics to track are viewability rate, reach and frequency, post-view conversions (not just post-click), and ideally a brand lift study to quantify the real impact on memorability or behaviour. Click-through rate alone is insufficient to evaluate a display campaign’s true performance.
Can programmatic display target local audiences in Quebec?
Yes. Programmatic buying provides access to quality Quebec media inventory with highly precise geographic targeting: region, city, or even a radius around a specific address. It is possible to reach audiences within credible, well-established local media environments, with the full flexibility and measurability of programmatic.
