This article covers two connected but distinct channels: online display advertising and digital out-of-home (DOOH) screen advertising. India's digital display segment alone was valued at ₹11,581 crore in 2025, making up 16% of total digital ad spend, according to Dentsu's 2026 report.
We'll answer the practical questions: what formats exist, how targeting works, how buying models differ, what things cost, how to measure success, and how to choose a media partner.
Key Takeaways
- Online display and DOOH serve different environments but can work together across a single campaign
- Targeting options range from contextual and geographic to first-party and retargeting, depending on the channel
- Pricing follows models like CPM, CPC, CPL, CPA, or negotiated packages, not one fixed rate
- Clicks alone don't measure success, especially for awareness and DOOH campaigns
- A clear objective and test budget matter more than chasing every available format
What Is Digital Display Advertising?
A digital display ad is a visual advertisement built from static imagery, animation, video, text, or interactive elements. It appears across websites, mobile apps, streaming environments, and digital screens. The format changes depending on where it's placed, but the goal stays consistent: catch attention without the viewer having to search for anything.
Online Display Versus DOOH
These two sit under the same umbrella but work differently:
- Online display ads run within digital properties (sites, apps, OTT platforms) and can support click-based journeys that lead to a landing page or purchase
- DOOH ads appear on physical screens in malls, transit hubs, commercial buildings, and retail spaces, where there's no click to follow, just visual exposure
Display Versus Search
Search ads respond to what someone is actively typing into a search bar. Display ads don't wait for that intent. They interrupt or complement browsing, which makes them useful for building awareness, nudging consideration, retargeting past visitors, or prompting an action at the right moment.
The Ecosystem, Simplified
Several players keep display advertising running:
| Role | What It Does |
|---|---|
| Advertisers & publishers | Buy and sell ad space |
| Ad networks & exchanges | Connect buyers and sellers at scale |
| Ad servers | Deliver creative and track impressions and clicks |
| DSPs | Let advertisers buy impressions across many publisher sites |
| Programmatic systems | Automate the matching of ad to audience in real time |
A campaign can support brand awareness or direct performance goals. Success depends on whether the creative, audience, placement, timing, and measurement method all point toward the same business goal.
Types of Digital Display Ads and Audience Targeting
Online Formats
Different formats suit different jobs:
- Banner and responsive ads – scalable visibility across desktop and mobile placements
- Video ads – storytelling and product demonstrations
- Rich media and interactive ads – deeper engagement through motion, forms, quizzes, or carousels
- Native and social-style ads – blend visually with surrounding content
- Shopping or product-led ads – display products, prices, or catalogue selections
DOOH Screen Formats
Public screen advertising in India typically includes:
- Static digital billboards
- Indoor retail and mall screens
- Transit and roadside displays
- Screens in corporate offices, residential complexes, airports, cinemas, and hospitality venues
Gautam Advertising's DOOH network spans malls, metro stations, airports, offices, residential complexes, and transit hubs across multiple Indian cities.
DOOH spend reached roughly ₹12.2 billion in 2025, about 18% of total out-of-home revenue, per EY's media report.
Targeting Approaches
| Approach | Online Display | DOOH |
|---|---|---|
| Contextual | Matches ad to surrounding content | Matches ad to venue type and time |
| Geographic | Device/browser location signals | Venue, area, or screen network selection |
| Demographic/interest | Platform-estimated segments | Dependent on screen location profile |
| First-party/retargeting | CRM and website visitor matching | Not applicable; relies on audience movement patterns |
Matching Format to Objective
- Awareness or launches → video, rich media, high-visibility DOOH screens
- Lead generation → interactive forms, retargeting, banner placements
- Footfall or bookings → geo-targeted DOOH near relevant venues, retail screens
- Recruitment or financial announcements → native ads, corporate building screens, transit displays
Online display, DOOH, social ads, and search ads each occupy a different spot in the funnel. Search responds to active intent and is highly clickable. Social blends into feeds and favours engagement. Display and DOOH build visibility, with DOOH generally non-clickable but strong on repeated, unmissable exposure.
How Digital Display and Screen Advertising Campaigns Work
A campaign typically moves through a defined sequence, whether it runs online, on screens, or across both.
- Define the brief – objective, audience, geography, timing, offer, budget, and desired action
- Select inventory – online publisher placements, specific screen networks, or a mix
- Prepare creative – correct dimensions, durations, file formats, and language versions
- Set delivery rules – targeting, scheduling, bidding terms, frequency caps, and brand-safety requirements
- Launch and monitor – track delivery against agreed KPIs and adjust where needed
Programmatic Buying in Plain Terms
When someone loads a page or app, automated systems evaluate the available ad slot within milliseconds. They select an eligible advertisement based on targeting, bid, context, and campaign rules. This is real-time bidding: each impression is offered through its own on-the-spot auction.
Direct and Negotiated Buying
Not everything runs through an auction. Premium publishers, high-visibility placements, event environments, or guaranteed venue screens are often sold through negotiated packages instead. These deals lock in price and terms upfront, unlike automated, impression-based buying.
Creative Delivery and Campaign Controls
Online assets need to be responsive across screen sizes; DOOH assets need to work at a fixed resolution and aspect ratio, viewed briefly from a distance. Controls that keep a campaign on track include:
- Frequency capping to avoid overexposure
- Exclusion lists and brand-safety filters
- Dayparting and geographic restrictions
- Creative rotation to prevent fatigue
A documented example: In February 2024, Aditya Birla Finance worked with Platinum Outdoor on a campaign featuring KL Rahul across urban centres and travel hubs, combining CGI and anamorphic digital screen sequences. The campaign was reported for its creative execution; specific reach or conversion numbers weren't published.
Coordinating inventory like this, comparing screen networks, negotiating rates, and building a schedule that fits the objective, is where media planning expertise matters.
Gautam Advertising's media planning and buying work helps businesses compare digital and DOOH opportunities and assemble a campaign suited to their goal and budget, rather than defaulting to whatever inventory is easiest to book.
Benefits, Costs, and Measuring Campaign Performance
Why Businesses Use Display and Screen Advertising
- Strong visual impact and brand recall
- Reach that scales from broad to tightly defined audiences
- Flexible formats for awareness, leads, sales, or footfall
- Retargeting for repeated exposure across a buyer's journey
- Coordinated online and offline visibility around a launch
Pricing Models
| Model | Best For |
|---|---|
| CPM | Impression or screen-exposure volume |
| CPC | Traffic or click-focused campaigns |
| CPL | Completed lead actions |
| CPA | Attributable conversions |
| Flat-rate/package | Premium publishers, venues, or exclusive screens |
Pricing typically moves with:
- Audience quality and targeting depth
- Venue reputation and placement prominence
- Campaign duration and seasonality
- Creative production, exclusivity, and reporting needs
There's no single rate across India's display or DOOH market, so treat quoted figures as context, not a benchmark.
What Counts as a "Good" CPM?
There isn't one number. A useful CPM benchmark depends on the market, the objective, inventory quality, audience fit, format, viewability, and what a conversion is actually worth to the business. Compare current, category-specific figures rather than a generic industry average.
Metrics That Matter
- Impressions and reach – how many people saw the ad
- Frequency – average repeat exposure per person
- Viewability – confirmed opportunity to see the ad
- CTR – click engagement for online formats
- Leads, conversions, footfall – the business outcome
- ROAS – commercial efficiency of spend
Clicks alone don't tell the full story, particularly for awareness or DOOH campaigns where there's nothing to click. Pair delivery data with QR scans, tracked landing pages, coupon codes, search-lift analysis, or enquiry source tracking for a fuller picture.
Budgeting Checklist for Small Businesses
- Define one clear objective
- Set a test budget before committing fully
- Prioritise placements relevant to your audience and geography
- Reserve separate funds for creative and tracking
- Agree on reporting terms upfront
- Scale only after reviewing quality and outcomes
Best Practices and Common Challenges
Creative That Works
- Lead with one primary message
- Show the brand early in the ad
- Use strong contrast and concise copy
- Make the call to action specific
- Design for the actual screen or ad ratio, not a generic template
Fast-moving animation might perform well online but fail on a DOOH screen viewed for two seconds from across a mall. Build creative for each environment separately rather than reusing the same asset everywhere.
Testing and Common Pitfalls
Test one variable at a time: headline, visual, offer, format, or time slot. Record what you learn before changing the next thing. Watch for these recurring issues:
- Ad fatigue – rotate creative and manage frequency caps
- Low-quality inventory or fraud – APAC desktop display fraud hit 1.7% in 2024 (DoubleVerify APAC report); prefer verified publishers and transparent reporting
- Privacy and signal loss – lean on consent-based, contextual, and first-party data
- Weak attribution – use dedicated landing pages, QR codes, UTMs, or offer codes
Compliance matters too. Ads should be legible, language-appropriate, and meet sector-specific disclosure rules, particularly for regulated categories like finance and real estate.
Choosing an Advertising Partner
Look for a partner that brings:
- Established media relationships across online and DOOH inventory
- Transparency on inventory and rates
- Clear creative specifications and scheduling reliability
- Optimisation support during the campaign, not just at launch
- Proof of appearance and post-campaign reporting

- Define the goal
- Pick the right format and placement
- Build creative suited to that environment
- Agree on buying and measurement terms

Frequently Asked Questions
What is a digital display ad?
A digital display ad is a visual online ad using images, video, text, or interactive elements on websites and apps. Unlike DOOH, it appears in a browser or app rather than on physical public screens.
What are the different types of digital display ads?
Common types include banner, responsive, video, rich media, interactive, native, shopping, and retargeting formats. The best choice depends on campaign objectives and placement.
What is the difference between Google Ads and display ads?
Google Ads is a full advertising platform covering search, display, video, shopping, and more. Display ads are one visual format within it, and they also run on other media platforms beyond Google.
How much do display ads cost?
Cost depends on the pricing model, audience, format, inventory quality, geography, duration, and targeting depth. Common models include CPM, CPC, CPL, CPA, and negotiated packages; there's no single universal rate.
What's a good CPM for display ads?
A good CPM is relative to your objective, audience quality, placement, viewability, and the market you're in. Compare current, relevant benchmarks for your category rather than relying on one industry-wide figure.
How do I advertise my small business?
Set one clear objective, define your audience, and pick a display or screen format with a trackable call to action. Start with a test budget, then scale what works with a transparent media planning partner.
