CTV Advertising: Winning 2026 Engagement with $30B at

Connected TV advertising is just part of the job now. By 2026, ad spend is projected to blow past $30 billion a year, so getting it right matters. If you want to actually get people’s attention, you have to move past just running your TV spot online. You need to understand the advanced CTV ad formats and what the platforms can really do, designing video experiences that people actually interact with.

Step 1: Setting Up Your Campaign in a Demand-Side Platform (DSP)

Any good CTV campaign starts with a solid setup in your Demand-Side Platform (DSP). For this walkthrough, we’ll use The Trade Desk, since it’s a common choice with tons of CTV inventory and good targeting options. You always have to start by defining what you’re trying to achieve and who you’re talking to.

1.1 Working through to Campaign Creation

Log into your The Trade Desk account. From the main dashboard, find and click “Campaigns” in the navigation pane on the left, then select “Create New Campaign”. You’ll have to name it, pick something that makes sense, like “Q3 2026 Product Launch – CTV Interactive,” so you can find it later.

1.2 Defining Campaign Goals and Budget

On the “Campaign Settings” page, find “Goal Type” and select either “Brand Awareness & Reach” or “Performance” based on what you’re being measured on. Honestly, if you’re trying to maximize engagement, a hybrid approach usually works best. After you input your total campaign budget and flight dates, I always set a daily cap. It’s a simple step that stops a single ad unit from blowing your whole budget in a day if it unexpectedly takes off in some weird corner of the internet.

1.3 Audience Targeting Configuration

This is where you get granular. Under the “Audience” tab, you’re going to layer your segments. You can start broad with demographics like age and household income, but then you need to get smarter. Add behavioral segments by picking categories like “Streaming Enthusiasts” or “Recent Auto Shoppers” from the third-party data providers that plug into The Trade Desk. The most important step here is uploading your own first-party data segments. This is your gold, website visitors, app users, CRM lists. The better your first-party data, the sharper your targeting will be. A 2025 IAB report confirmed that campaigns using first-party data smoke those that just use third-party segments in CTV.

Pro Tip: Geo-Targeting Specificity

Don’t just target by state. That’s lazy. Use zip codes or Designated Market Areas (DMAs), especially if your product or service is regional. For instance, if you’re pushing a new restaurant chain, targeting a handful of neighborhoods in Atlanta, Georgia, is going to work a lot better than blasting the entire state. You can also exclude specific areas, a tactic that’s often forgotten but is great for efficiency.

Common Mistake: Over-targeting

While you want to be specific, you can definitely overdo it. Remember that CTV audiences are often smaller than what you’d find in a huge display buy. If you keep adding targeting layers, you might shrink your addressable audience down to nothing, so keep an eye on the potential reach estimate as you build out your segments.

Step 2: Selecting and Customizing Advanced CTV Ad Formats

The days of just running a static pre-roll ad are over. For 2026, you’ve got to use more innovative CTV ad formats. The Trade Desk, and other big DSPs, have a whole suite of options that go way beyond a simple linear video.

2.1 Interactive Overlays and QR Codes

In your ad group settings, go to “Creative Type” and pick “Interactive Video Ad”. This lets you put clickable elements right on top of your video. You upload your main video file, and then you can use a drag-and-drop tool to add things. A retail brand, for instance, could add a “Shop Now” button that pops up a QR code on the screen. The viewer scans it with their phone and lands directly on the product page. It just gets the customer there faster. Make sure the QR code is big enough to be scannable from the couch and stays on screen for at least 10 seconds. A recent eMarketer forecast is calling for a 40% jump in QR code use in CTV ads by 2027, so it’s becoming standard practice.

2.2 Shoppable Ad Experiences

For any direct-to-consumer brand, shoppable CTV ad formats are a huge opportunity. Select “Shoppable Video Ad” as your creative type. This is where you can tag individual products in your video. When a viewer shows interest (maybe they hover over an item with their remote or click a button), a small storefront pops up on the side of the screen where they can browse and buy something using stored payment info or a QR code for mobile checkout. It keeps the disruption low and captures that impulse buy. Be warned: the creative lift for these is bigger. You need good product photos and a solid back-end to handle the orders.

2.3 Dynamic Creative Optimization (DCO) for Personalization

Under the “Creative” section, you have to turn on “Dynamic Creative Optimization”. You’ll upload a bunch of different ad components, headlines, calls-to-action (CTAs), product shots, even slightly different video clips. Then, The Trade Desk’s DCO engine mixes and matches these pieces to serve the most relevant combination to each viewer based on their data, location, or past behavior. A travel ad could show beaches to someone in a cold state and mountains to someone in a warm one. When an ad is that personalized, it feels like a helpful suggestion, not an annoying interruption.

Expected Outcome: Increased Click-Through Rates

When you use interactive and shoppable formats with DCO, you should see your engagement metrics go up, specifically your click-through rates (CTR) on the interactive parts and your direct site visits. The whole point is to give viewers a clear and easy way to do something.

Step 3: Implementing Advanced Measurement and Attribution

Attribution for CTV is tough. People see an ad on their TV and then pull out their phone to buy something days later, so you need an attribution model that can connect those two events, especially for engagement-focused campaigns.

3.1 Cross-Device Tracking and Attribution

Inside The Trade Desk, go to “Measurement & Attribution” in your campaign settings and make sure “Cross-Device Graph” is on. This feature tries to link an ad impression on a TV to an action on a phone or laptop in the same household, using a mix of data to make the connection. This is how you see the actual influence your CTV spend has across the entire funnel. I’ve seen too many campaigns get their ROI wrong because they only tracked direct CTV conversions and completely missed all the actions happening on mobile as a result of the ad.

3.2 Integrating with Third-Party Measurement Partners

For deeper analysis, you need to connect your DSP to a third-party measurement partner like Nielsen ONE or Branch Metrics (especially for app install attribution). You can find this under “Integrations” in The Trade Desk. This gives you an independent check on your numbers for reach, frequency, and conversions which is way more credible. For serious marketers, using a third-party for validation isn’t optional.

3.3 Post-Impression and Post-Click Conversion Windows

You need to be thoughtful about your conversion windows. For CTV, a longer post-impression window (like 30 days) usually makes more sense than it does for a direct-response display ad. A viewer might see your ad, think about it for a few days, and then finally make a purchase on their laptop. Go into your “Attribution Model” settings and adjust these windows so CTV gets the credit it deserves.

Pro Tip: A/B Testing Attribution Models

Don’t just pick one attribution model and stick with it forever. Run some A/B tests on different models (last-touch vs. linear vs. time decay) and see which one actually lines up with your sales cycle. This is a great way to show the value of your top-of-funnel CTV ads that last-touch models usually ignore.

Common Mistake: Ignoring View-Through Conversions

So many marketers are obsessed with clicks. But on CTV, a huge part of the value is in branding and awareness, which means view-through conversions (when someone takes action after *seeing* an ad, not clicking it) are incredibly important. Your measurement has to account for these, especially when you’re using interactive ads that prompt someone to grab their phone.

Step 4: Using Sequential Messaging and Retargeting

Engagement is a conversation you build over time, not a single ad impression. CTV is perfect for telling a story with sequential messaging and smart retargeting.

4.1 Implementing Sequential Ad Delivery

In your ad group settings, go to “Frequency Capping & Sequencing” and choose “Sequential Messaging”. You can upload a series of creatives and set the order and timing for how a viewer sees them. For instance, a viewer could see a 15-second brand spot first, then a 30-second ad showing a product feature a few days later, and finally a 60-second customer testimonial the following week. This lets you build a narrative. This is the way to go for complex products or services that need a little more explanation.

4.2 Cross-Device Retargeting

You should always set up separate ad groups just for retargeting. You can target people who saw your CTV ad or even clicked on an interactive element but didn’t convert. Then you can hit them with a different ad on their phone or even back on their TV, maybe with a special offer. The Trade Desk lets you build audience segments from CTV ad exposure that you can then retarget anywhere. As even Google’s own docs on remarketing will tell you, this kind of personalized retargeting can really push up conversion rates by keeping your brand front and center.

Expected Outcome: Improved Conversion Rates and Brand Recall

When you sequence your ads and retarget people who’ve already shown interest, your conversion rates and brand recall will get better. This approach just makes sense. It follows the customer’s actual path instead of pretending it’s a straight line.

Step 5: Continuous Optimization and A/B Testing

CTV changes fast, which means your campaigns can’t be ‘set it and forget it.’ You have to be optimizing constantly.

5.1 A/B Testing Creative Elements

You should always be running A/B tests. Test different interactive elements, CTAs, video lengths, even where you place the QR code. In The Trade Desk, it’s as simple as duplicating an ad group and changing one single variable. Let it run for two weeks and see what the data says. Did a different button color work better? Was a 15-second spot better at grabbing initial attention than a 30-second one? This is the kind of data that justifies your budget.

5.2 Monitoring Frequency and Recency

Keep a very close eye on your frequency caps. Too many ads burn people out and create a negative feeling about your brand. Too few and you’re leaving money on the table. You can find these caps under “Frequency Capping & Sequencing” in the ad group settings. The right number varies by industry and campaign goal, but my general rule is to start with a cap of 3-4 impressions per user per week and then adjust it based on what the engagement numbers are telling you.

5.3 Analyzing Viewer Engagement Metrics

You have to look beyond the basic metrics like impressions and clicks. Pay close attention to the numbers specific to interactive CTV, like QR code scan rates, interactive element click-through rates, and completion rates for shoppable experiences. These numbers tell you exactly how well your ads are working. If scan rates are low, your QR code probably isn’t big enough or the CTA is weak. If people are bailing on shoppable experiences, your checkout flow has friction.

Getting real engagement with CTV ad formats in 2026 is all about using data to run interactive, personal, and shoppable ads. It’s about moving beyond just delivering a video and instead creating an experience that connects with people and produces results you can measure.
