Fundamentals of Digital Advertising on TV and Connected TV
Television is not what it was ten years ago. If you run a mid-sized digital agency or work with clients looking to expand their reach, you have likely noticed that linear TV budgets are migrating toward something more measurable and flexible. Digital advertising on connected television represents that natural evolution where you can combine the visual impact of the big screen with the precision of digital marketing.
The numbers support this trend. According to The Media M Group, on-demand content penetration will reach 55% by 2027. This means that more than half of your potential audience consumes content on streaming platforms, not traditional channels. For agencies managing diverse client accounts, understanding how to buy digital advertising on television has become an essential skill.
The CTV ecosystem offers something that traditional TV never could: actionable, real-time data. You can know exactly how many people watched your entire ad, on which device they did so, and what actions they took afterward. This transparency completely changes the conversation with your clients when you present campaign reports.
Differences Between Linear TV and Connected TV (CTV)
Linear TV operates on a mass-broadcast model. You buy a slot at a specific time and hope your target audience is watching that channel at that moment. It is like casting a net into the ocean hoping to catch the right fish. CTV flips this logic: you first identify your audience and then show them the ad regardless of what content they are watching.
In practical terms, linear TV requires long negotiations, months-long contracts, and minimum budgets that can exceed hundreds of thousands of pesos. CTV allows you to launch campaigns with much more accessible investments and adjust spending based on the results you are getting. For an agency managing multiple accounts with varying budgets, this flexibility is pure gold.
Another differentiating factor is measurement. In linear TV, you rely on estimates based on audience panels. In CTV, you get real metrics on impressions, completed views, and engagement. When your client asks how many people saw their ad, you can provide an exact number, not a statistical projection.
OTT ecosystem and streaming devices
OTT stands for "over-the-top" and refers to any content delivered to the user via the internet, bypassing traditional cable or satellite providers. Within this ecosystem, we find platforms like Pluto TV, The Roku Channel, and services with AVOD (advertising video on demand) models that monetize through advertising.
The devices used to consume this content are diverse: smart TVs, streaming devices like Roku or Amazon Fire Stick, game consoles, and even computers connected to large screens. According to Marketing Directo, YouTube consumption on televisions reached a 12.8% share in the United States in 2024. Young people aged 16 to 24 consume an average of 81 minutes of streaming content daily.
For agencies, this means the audience is fragmented but accessible. You don't need to buy spots on 20 different channels; you can reach your target audience across multiple platforms with a single, well-configured campaign.
Buying Models: Direct vs. Programmatic
There are two main paths for acquiring advertising inventory on CTV, and each has specific advantages depending on the type of campaign and client you are managing. Understanding when to use each model can make the difference between an efficient campaign and one that wastes budget.
Direct buying gives you total control over where your ads appear and generally guarantees premium inventory. Programmatic buying offers scale, efficiency, and the ability to optimize in real-time based on performance data.
Direct buying with publishers and networks
Direct buying involves negotiating directly with streaming platforms or their sales representatives. You establish an agreement for a specific number of impressions at a fixed CPM over a set period. This model works well when you need to guarantee presence in specific inventory or when your client requires exclusivity in certain content.
The disadvantages are clear: long negotiation processes, high minimum investment commitments, and little flexibility to adjust the campaign once it starts. For mid-sized agencies managing variable budgets, this model can be restrictive.
However, some publishers offer more flexible terms. Platforms like Masha allow access to premium inventory on services like Pluto TV and Roku without the need for extensive negotiations or prohibitive minimums. You can launch campaigns starting at $2,000 MXN and scale based on results.
Real-Time Bidding (RTB) and Private Marketplaces
RTB (Real-Time Bidding) is the backbone of programmatic advertising. Every time a user is about to watch content, an instant auction takes place where multiple advertisers compete to show their ad. It all happens in milliseconds, before the content loads.
As GoDaddyexplains, programmatic buying uses algorithms to determine when and where to deliver content to target consumers, based on the collection and evaluation of data from thousands of individual users. This means your ad is only shown to people who meet your audience criteria.
Private Marketplaces (PMPs) offer a middle ground. They are restricted auctions where only invited advertisers participate, generally with access to higher-quality inventory. For agencies seeking a balance between programmatic efficiency and brand control, PMPs are an attractive option.
Advanced Segmentation and Audiences in Digital Television
The ability to segment is arguably the most significant advantage of CTV advertising over traditional TV. You no longer rely on demographic assumptions based on program type; you can target specific individuals based on real behavioral data.
Using First-Party Data for Personalization
First-party data is information that you or your client collect directly from your own users: purchase history, website interactions, and email lists. This data is particularly valuable because it represents people who already have a relationship with the brand.
You can upload these audiences to CTV platforms to create retargeting campaigns on the big screen. Imagine showing a TV ad to someone who abandoned a shopping cart three days ago. The impact is significantly greater than a banner on a webpage.
You can also use this data to create lookalike audiences. The platform identifies patterns in your best customers and finds users with similar characteristics who don't yet know the brand. It is smart prospecting at a television scale.
Geographic and Behavioral Segmentation
Geographic segmentation in CTV goes beyond zip codes. You can target users in specific cities, states, or even particular metropolitan areas. For local businesses or regional campaigns, this eliminates the waste of showing ads to people who could never become customers.
Behavioral segmentation analyzes content consumption and browsing patterns. If someone frequently watches travel content, they are likely to respond better to ads for airlines or travel agencies. This additional layer of precision increases message relevance and improves response rates.
Trust in these ads is also high. According to Marketing Directo, 83% of users in mature markets trust the ads they see on CTV. This credibility translates into better results for your campaigns.
Platforms and Tools for Managing Campaigns
The market for CTV advertising buying tools has grown exponentially in recent years. According to PWC, CTV advertising revenue will grow at an annual rate of 10.2%, reaching €1.95 billion by 2029. This growth drives constant innovation in management platforms.
For mid-sized agencies, the key is finding tools that offer robust functionality without requiring dedicated technical teams or extensive learning curves.
Specialized Demand-Side Platforms (DSPs)
A DSP is the interface from which you buy programmatic advertising inventory. These platforms connect to multiple inventory sources and allow you to manage campaigns, set bids, and analyze results from a single location.
Specialized CTV DSPs offer specific features such as cross-device frequency optimization, deduplicated reach reporting, and access to premium streaming inventory. Well-known names include The Trade Desk, DV360, and vertical platforms focused on video.
For agencies seeking simplicity without sacrificing access to quality inventory, options like Masha consolidate planning, generative AI ad creation, launch, and measurement into a single interface. You can go from concept to live campaign in days, not weeks, with real-time reporting that facilitates continuous optimization.
Choosing the right DSP depends on the volume of campaigns you manage, the markets where you operate, and the level of control you need over your media buying.
Critical Steps for Ad Implementation
Having the right strategy is useless if execution fails. Technical and operational details determine whether your campaign runs smoothly or gets stuck in reviews and rejections.
Technical specifications and video formats
CTV ads have specific requirements that vary slightly by platform, but there are general standards you should follow. The minimum resolution is usually 1920x1080 (Full HD), although more platforms are increasingly preferring 4K. Accepted formats typically include MP4 and MOV with H.264 codec.
The standard duration is 15 or 30 seconds, though some platforms accept 6-second formats for quick awareness campaigns. Audio must be normalized and volume must meet broadcast standards to avoid rejections.
A common mistake is reusing creatives designed for social media without adapting them. CTV content is viewed on large screens, from a distance, and usually with audio on. Small text that works on mobile is illegible on TV. The first three seconds must capture attention because, unlike YouTube, many CTV formats do not allow users to skip the ad.
Budget and bidding configuration
Budget configuration in CTV generally works with CPM (cost per mille) or CPCV (cost per completed view). CPMs vary significantly depending on inventory quality, applied targeting, and competition at the time of the auction.
For programmatic campaigns, you can set maximum bids and let the algorithm optimize, or set target CPMs and adjust based on performance. The initial recommendation is to start with moderate budgets, evaluate results for one or two weeks, and scale what works.
Pacing also matters. You can configure your budget to be distributed evenly throughout the campaign or allow it to spend faster when high-quality inventory opportunities arise. For campaigns with specific deadlines, such as seasonal promotions, aggressive initial pacing may be preferable.
Measuring Success and Return on Investment (ROI)
Without proper measurement, CTV advertising loses its main advantage over traditional TV. Establishing clear KPIs from the start and setting up tracking correctly is essential to demonstrate value to your clients.
Key metrics: VTR, reach, and frequency
The VTR (Video Through Rate) indicates the percentage of users who watched your ad to the end. In CTV, this metric is usually high because many formats are non-skippable, but it remains useful for comparing creatives against each other.
Reach represents the number of unique users who saw your ad at least once. Frequency indicates how many times, on average, each user was exposed to the message. The balance between both metrics is critical: too little frequency fails to build recall, while too much causes fatigue and wastes budget.
A general rule of thumb is to aim for a frequency of 3 to 7 exposures per user during the campaign period. Less than three rarely generates impact; more than seven typically shows diminishing returns. Advanced platforms allow you to set frequency caps to optimize automatically.
Cross-device conversion attribution
The biggest measurement challenge in CTV is connecting ad exposure to subsequent actions. Someone sees your ad on their living room TV and then makes a purchase from their phone or laptop. Without cross-device attribution, that conversion looks organic when it was actually influenced by the campaign.
There are methodologies to solve this: identity graphs that connect devices within the same household, incrementality studies that compare exposed versus non-exposed groups, and conversion pixels that track website visits after exposure.
For agencies managing multiple clients, it is important to set realistic expectations. Attribution in CTV will never be as direct as in digital performance marketing, but current methodologies allow you to demonstrate impact with enough confidence to justify the investment.
Next Steps for Your Agency
Digital advertising on connected TV has moved beyond the experimental phase to become an essential channel within the media mix. Agencies that master its buying and optimization will have a significant competitive advantage in the coming years, especially considering the projected market growth.
What makes this moment different is accessibility. You no longer need million-dollar budgets or specialized teams to run effective streaming TV campaigns. Tools like Masha democratize access, allowing agencies of any size to offer this service to their clients with transparent pricing starting at $0.01 per view and no restrictive contracts.
