Content and Creative

Hey there, digital marketers! While many teams focus on search and organic social, display advertising has become a data-driven growth channel in its own right. Programmatic buying now accounts for over 90% of US digital display ad spending, according to eMarketer, which projected that US programmatic display spending would exceed $180 billion in 2025. That shift is changing how businesses acquire customers.

What's interesting is how this shift separates leaders from laggards. Teams that combine data-driven targeting, strong creative and sound measurement tend to get far more from the same budget than teams running old-school campaigns.

Two Sides of Display Advertising: Programmatic and Traditional

Display advertising runs on two distinct buying methods, and every digital marketer should understand both. Programmatic display advertising uses software and algorithms to buy ad space in real time, weighing large amounts of data to serve an ad to the right potential customer as a page loads. Traditional display advertising relies on direct negotiation with publishers; it offers guaranteed placements and access to premium inventory, but it takes far more hands-on work.

The numbers explain why Basis Technologies' 2025 trends report calls programmatic a reliable mainstay: programmatic has taken more than 90% of US digital display ad dollars since 2023, and global programmatic spend reached $595 billion in 2024. Traditional display is still relevant for high-end brand awareness campaigns that need specific editorial environments or guaranteed impression delivery.

Now for performance. The in-depth analysis by Keywords Everywhere puts the Google Display Network's average click-through rate under 0.5%. Surface metrics like that miss the bigger picture, though: viewable display ads have four times higher conversion rates than ads that don't meet the MRC viewability standard, so placement quality matters more than raw volume.

Mobile is now central to display, and Statista's mobile viewability data tracks how often mobile web display ads are actually in view (second half of 2019 to first half of 2022). That makes mobile-first creative essential: ads built for thumb-friendly interaction that load quickly.

The Tech Behind What's Working in Modern Display

The technology behind display advertising separates strong campaigns from weak ones. Real-time bidding runs through demand-side platforms (DSPs), which analyze user data, contextual signals and campaign rules to set bid amounts in milliseconds. Supply-side platforms (SSPs) work for publishers, selling inventory in auctions to the highest qualified bidders while applying brand safety controls.

Real-time bidding is what makes programmatic work. As Amazon Ads' guide to real-time bidding explains, ad inventory is sold in a real-time auction, typically on a per-impression basis, with an auction run each time a user visits a site or app. Platforms then use machine learning to estimate how much each impression is worth, drawing on signals such as purchase history, browsing activity and seasonality.

Data management platforms (DMPs) form the foundation, collecting 1st, 2nd and 3rd party data to build detailed audience segments. Privacy rules are pushing advertisers to rely more on first-party data, and platform choice matters too: Agilityads' comparison of programmatic and Google Display cites The Economist's campaign, which achieved a 64% subscription increase and a 6:1 ROI through Google Display.

Creative optimization is dynamic: algorithms can test many combinations automatically. Headlines, images, calls to action and color schemes change in response to live performance data, so winning variations scale while weak ones are switched off.

Integration matters for every campaign. The best platforms connect with CRM, email marketing and analytics tools, so you can measure closed-loop attribution and link display advertising to the entire customer funnel.

Case Study: Seltzer Goods' 785% Sales Increase

When COVID-19 hit Seltzer Goods' wholesale business, the brand needed more direct-to-consumer sales to offset the losses. Its answer was a focused Facebook ads campaign, and the Inflow case study breaks down how it worked.

Seltzer Goods used Inflow's "See, Think, Do" approach to Facebook ads, launching with a single campaign aimed only at cold audiences rather than a large retargeting push.

The broader lesson is simplicity. Clean product photography and benefit-led copy usually beat generic brand messaging, and a single, well-defined campaign is easier to read and optimize.

The scaling method proved crucial. Instead of dramatic budget jumps that can break a campaign, Seltzer Goods raised budgets by 10-15% every couple of days, as long as ROAS stayed at 5X or higher. That kept costs under control while the campaign kept learning.

The results were strong. Within 30 days, sitewide sales rose 785%, equal to the previous seven months' total, and the campaign accounted for 25% of monthly revenue. ROAS reached 4.5X overall, the figure Single Grain's roundup of Facebook ads case studies also reports, and 9.68X under Facebook's own attribution. Cost per acquisition stayed under $10.

Cross-Industry: Lessons for B2B Display

B2B marketers often dismiss paid social and display as B2C tactics, but Inc.'s Facebook ads case studies suggest otherwise. In one, HubSpot, a B2B marketing software company, A/B tested its Facebook ads first by age group, then by job titles such as "marketing manager" and "chief marketing officer," and then by image text overlays. The article reports 71% more sales directly attributable to Facebook, a 15% ROI increase from Facebook, and 39% more website visitors from Facebook.

Role-based targeting works best with pain-point-driven creative. Instead of generic "increase ROI" messaging, ads can speak to specific problems, such as "cut reporting time" or "eliminate manual data entry." Clear visuals, like charts and screenshots, frame the value proposition quickly.

LinkedIn tends to offer precise professional targeting at a higher cost per click, while Facebook is often cheaper for building awareness. Many B2B teams combine the two to balance reach and lead quality.

Test formats by audience segment. Preferences for video, static images or in-depth infographics can differ by role and seniority, and only your own data will show which works.

Attribution matters just as much. Last-click models miss display's influence on pipeline when prospects convert through another channel. View-through conversion tracking can surface that influence, as long as the lookback window is set conservatively.

Healthcare Display Advertising: Staying Compliant While Driving Performance

Healthcare marketing has its own challenges that make advertising both important and difficult. OUTFRONT's case study on Ro shows how the direct-to-patient telehealth company used New York subway and commuter rail ads to build awareness after its 2017 launch; Ro's CEO is quoted saying sales went from zero to $1 million in a month.

In healthcare, compliance shapes every creative decision. Privacy rules such as HIPAA limit how patient information and testimonials can be used, and health claims need substantiation. Creative that emphasizes convenience, access and professionalism, rather than promised outcomes, is the safer route, supported by clean, trustworthy visual design.

Geotargeting matters in healthcare campaigns, because access to care and to the service itself varies by location. Time-of-day testing can also show when your audience researches health questions.

Attribution is especially hard in healthcare. Patients often research for a long time before converting, so last-click models tend to undercount display's role in patient acquisition.

Choose platforms based on audience behavior. Facebook can build reach efficiently, the Google Display Network can reach people researching related topics, and LinkedIn can reach healthcare professionals and insurance decision-makers.

Which Display Ad Format Is the Best Choice for You?

Creative format choice affects campaign success more than many marketers expect. Google's rich media guidelines set the technical rules rich media creatives must follow in Display & Video 360, from asset limits to supported formats such as in-banner video and fullscreen expandable units. Static banners are cheap to produce and perform steadily, while rich media adds interaction at a higher production cost.

Video has become a mainstream display format. In Porch Group Media's 2025 display trends article, 69% of marketers report using video ads, close to the 70% who use banner ads. Video usually costs more to produce than static creative, so calculating ROI is essential.

Interactive experiences turn passive viewing into active participation. Adbeat's 2019 introduction to HTML5 rich media ads cites Adform data showing that rich-media HTML5 ads boost click-through rates by 267 percent. Keep file sizes light so ads load quickly on mobile.

Native advertising blends content and promotion, and native formats are among the trends tracked in Amra & Elma's display performance statistics. Success means matching the publisher's editorial style while including the clear ad disclosure the FTC requires.

IAB standard sizes still matter for reach. Publift's guide to IAB standards names 300x250, 728x90 and 160x600 as the three most common standard sizes, and lists others such as the 320x50 smartphone banner and the 300x600 portrait unit.

Choosing Platforms: Where Your Budget Works Hardest

Platform choice affects reach and cost-effectiveness. Google Display Network (GDN) can reach a large portion of global internet users, according to WordStream's guide to the Google Display Network. Its inventory includes YouTube video, and Performance Max campaigns rely heavily on Google's Smart Bidding.

According to Improvado's comparison of DV360 and The Trade Desk, The Trade Desk is known for its transparency, but its minimum spend commitments can range from $100,000 to over $1 million per quarter. DV360's main strength is its integration with the Google Marketing Platform. Amazon DSP, which that comparison doesn't cover, draws on Amazon's shopping data.

Meta's Audience Network extends Facebook's targeting beyond its own apps, but iOS privacy changes have reduced its effectiveness. An analysis of Amazon's advertising growth puts Amazon's ad revenue growth at roughly 22% year over year in the first quarter of 2026, helped by first-party shopper data that doesn't depend on third-party cookies.

Emerging platforms deserve consideration for some use cases. Pinterest can suit lifestyle and home goods categories, and TikTok's ad platform is a strong way to reach Gen Z, though its measurement tools are still maturing.

Costs differ by platform and audience quality. Bobsled Marketing's Amazon DSP case study describes a beauty and cosmetics brand that saw steady increases in product sales and new-to-brand conversions, and cites Amazon's claim that display can reach 10X more high-intent shoppers than PPC alone. Premium publishers usually charge more, in exchange for stronger placement quality and brand safety.

How Privacy Changes Are Reshaping Display Advertising

Privacy regulations are changing how display advertising works, creating challenges and opportunities for marketers who can adapt. WeAreAXM impact analysis reported in 2021 that App Tracking Transparency, introduced with iOS 14.5, produced an average opt-in rate of 45%, and estimated that about 388 million users, or 10% of users, are unidentifiable on average across apps.

The Privacy Sandbox was Google's effort to keep ads relevant with less cross-site tracking. In July 2024, as Google's Privacy Sandbox update explains, Google said it would no longer deprecate third-party cookies and would introduce a user choice in Chrome instead. The page now notes that some Privacy Sandbox technologies are being phased out.

State privacy laws add complexity. eMarketer's privacy trends report notes that as more states pass comprehensive privacy legislation, it will keep getting harder for advertisers to use consumer data, and that only 9.9% of US consumers feel they always understand what they are consenting to when they accept cookies. Each law sets its own rules for data collection, consent and opt-outs.

AdExchanger's review of 2024 privacy trends highlights three shifts: Google dropped its plan to phase out third-party cookies, privacy-enhancing technologies are maturing, and the FTC has warned that data clean rooms are not automatically private. First-party data remains key, as companies build direct customer relationships through email subscriptions, loyalty programs and account registrations, and contextual targeting is getting renewed attention.

Properly configured data clean rooms let advertisers and publishers collaborate without sharing user-level information. Contextual technology analyzes page content and the surrounding environment to keep ads relevant without relying on personal data, as GumGum's cookieless targeting guide explains.

Measuring Success: Giving Display the Credit It Earns

Measurement decides whether display looks like waste or value. First-touch and last-touch models give all the credit to one interaction, which undervalues display's role in awareness and consideration. Viewability matters too: MonetizeMore's viewability guide notes that advertisers may cut rates or stop bidding when a publisher's viewability falls to around 30%.

Multi-touch attribution spreads conversion credit across every touchpoint, which shows display's real contribution. Cost benchmarks help set expectations: WordStream's conversion rate benchmarks put the average cost per lead for display and video ads at $114.44.

Viewability standards shape how performance is measured. Google's Active View guidelines define a viewable display impression as 50% of the ad's pixels in view for a continuous second (30% for very large ads). For social placements, Brafton's social advertising benchmarks put Facebook's average click-through rate across industries at 0.90%, based partly on older WordStream and AdStage data.

Brand lift and incrementality studies offer proof beyond response metrics by comparing exposed audiences with a control group. They show display's effect on awareness, purchase intent, branded search and customer lifetime value.

Cross-device tracking is hard but essential for assigning credit correctly. People research on mobile, compare on desktop and buy across screens, so you need reliable identity resolution to connect those touchpoints. Leading platforms combine deterministic matching from login data with probabilistic inference to follow the customer journey.

The True ROI of Display Advertising

That brings us to the question every CMO asks: does display advertising pay its way? ReportGarden's guide to ROI metrics doesn't give display-specific ROAS benchmarks, but it explains how to calculate ROAS and ROI and cites a Nielsen study finding that digital ads yield 300% higher ROAS than traditional media. Results vary by industry and sales cycle, and B2B campaigns usually need longer measurement windows.

Firework's marketing ROI figures show how much execution matters: retargeted ads can deliver 10x higher click-through rates and a 70% boost in conversion rates compared with standard display ads. Poorly targeted campaigns, by contrast, can burn through budget without results.

Industry benchmarks help set expectations. For Facebook ads, finance has a high average cost per click of $3.77, according to Keywords Everywhere's statistics roundup, so higher client lifetime value has to justify the cost. Looking only at the point of conversion also misses display's longer-term effect on acquisition and retention.

Attribution windows strongly affect ROI calculations. Counting view-through conversions can make a campaign look much stronger than click-only crediting, and long lookback windows can inflate results by giving display credit for conversions that would have happened anyway.

Customer lifetime value analysis is the truest measure of ROI. If display-acquired customers stay longer or spend more, a higher acquisition cost can be worth it over the life of the relationship.

Future Trends Reshaping Display Advertising

Connected TV is one of the fastest-moving parts of the display market, and its buying is now largely automated: AdExchanger's CTV analysis reports that programmatic accounts for three-fourths of all CTV transactions. CTV combines TV's emotional power with digital's targeting precision.

"The display advertising ecosystem has evolved into a sophisticated data-driven marketplace where creative excellence meets algorithmic precision. Success isn't about spending more money, it's about understanding how programmatic technologies can amplify human creativity to reach the right audience at the exact moment they're ready to engage."

Tessar Napitupulu, Founder and CEO of Arfadia

According to Marketing Dive's report on IAB video research, advertisers increasingly prioritize business outcomes such as sales or store visits as KPIs for digital video, and 54% of CTV buyers prioritize business outcomes over traditional brand awareness measures.

AI is changing how creative is made and optimized. WordStream's AI marketing trends expect hyper-personalization at scale, more mature AI content creation with human review, and AI-optimized ad campaigns becoming the norm, though that automation can reduce advertisers' control and transparency.

Best Practices for Display Advertising

Great creative starts with respect for the user experience and a clear message. Keep text overlays short, leave plenty of white space, and use high-contrast call-to-action buttons. Watch for creative fatigue and refresh on a schedule. Supply quality matters as much as creative: Digiday's programmatic report describes how fear of the open auction is pushing buyers toward private marketplaces and programmatic guaranteed deals.

Precise targeting beats a spray-and-pray strategy. Layer demographic filters, behavioral interests and contextual signals for relevance, set frequency caps to avoid burnout, and use exclusion lists to prevent brand safety incidents and wasted overlap. CTV audiences are large: MNTN's Connected TV data cites 90 percent of households using internet-connected TV devices at least once a month, US CTV ad spending of $28.79 billion in 2024, and 64 percent of US CTV users preferring ad-supported content if it lets them pay less.

Landing page alignment can make or break performance, no matter how good the ad is. Message match between ad and landing page is essential, pages should load fast, and mobile optimization isn't optional.

Platform minimums are only a starting point; budget allocation needs strategic thinking. Start with a test budget you can afford to learn from, scale the campaigns that prove themselves, and reserve a share of display spend for testing new platforms, formats and targeting.

Common mistakes are surprisingly consistent. Targeting too broadly wastes budget on the wrong audiences, while targeting too narrowly limits scale and drives up costs. Ignoring creative fatigue lets performance decline even when the budget stays steady. Even with accurate targeting, a poorly aligned landing page interrupts the user journey. And weak attribution modeling consistently understates display's role in customer acquisition and retention.

7 Common Questions About Display Advertising

How much should I spend on display advertising?

Start with a test budget you can afford to learn from, then increase spending on what works. Base allocation on your own performance data rather than on what others in your industry do, and keep part of the display budget for testing new platforms and approaches.

Should I use programmatic or traditional display buying?

For most advertisers, programmatic should carry the bulk of display spending; it already accounts for over 90% of US display ad spending, according to eMarketer. Keep traditional buys for premium placements that require guaranteed delivery, specific editorial environments or exclusive inventory.

How can I measure display ad success beyond clicks?

Look at viewability rates, view-through conversions with sensible lookback windows, brand lift studies that measure awareness, and multi-touch attribution that shows the real customer journey. Click-through rates matter less than impact on conversions and lifetime value. Incrementality testing shows true effectiveness against an organic baseline.

Which creative formats work best for which objectives?

Match the format to the goal. Video tends to suit awareness campaigns but costs more to produce, so ROI scrutiny matters. Rich media adds interaction; Adform data cited by Adbeat in 2019 found that rich-media HTML5 ads boost click-through rates by 267 percent. Direct response campaigns often do well with clean static creative and a direct call to action.

How will privacy changes impact my display advertising strategy?

Start building first-party data assets now through email capture, loyalty programs and account registrations. Lean into contextual targeting, and follow Google's Chrome privacy updates, since several Privacy Sandbox technologies are being phased out. Build plans that can handle ongoing signal loss rather than counting on privacy rules being relaxed.

Which platforms should I focus on?

Meet your audience where it is already active. The Google Display Network offers broad reach, Meta still performs well with interest-based targeting despite iOS constraints, Amazon DSP brings purchase-intent data, and The Trade Desk is known for transparency in sophisticated campaigns. Test several platforms systematically, then concentrate spending on the winners.

What's a good guideline for rotating creative?

Check performance weekly and refresh creative when click-through rates fall well below their peak or frequency climbs too high. For always-on campaigns, that often means new creative every few weeks. Seasonal campaigns may need fewer updates, while competitive industries may need more.

Machine learning can adjust bids, targeting and creative together, in small steps, far faster than any person could. According to analysis by Deusens, an immersive-technology company, platforms such as The Trade Desk and Google's DV360 use AI to analyze big data and change bids in real time, and AI can personalize targeting using browsing behavior, location and past purchases. Strategy and creative concepts still depend on human judgment.

Augmented reality advertising is moving from experiment to an option worth testing. It enables immersive brand experiences that turn passive viewing into interactive engagement, though costs and results still vary widely.

Conclusion: Your Display Advertising Success Begins Here

Display advertising is one of the biggest growth opportunities in digital marketing for organizations ready to use it well. Seltzer Goods' 4.5X ROAS wasn't luck; it came from a disciplined process that combined clear strategy with careful execution.

The technology exists, and the platforms offer precise targeting at scale. Whether you benefit before your competitors do depends on how seriously you invest in mastering display advertising now.

Remember: today's display advertising rewards depth over breadth. Instead of spreading budget thinly across every channel, successful marketers find their strongest channels and optimize them carefully. They test new formats while keeping the ones that work, and they track what counts, customer lifetime value and incremental revenue, not shallow metrics that can hide weak performance.
