Key Takeaways
- Use server-side ad insertion (SSAI) to get around ad blockers. It makes for a smoother user experience and we’ve seen it push completion rates up by 15%.
- Put at least 30% of your CTV budget into programmatic guaranteed deals. It’s the best way to get predictable reach on premium inventory.
- Combine geo-fencing with your own first-party CRM data. Targeting high-value customers within a 5-mile radius of your retail spots can get you a 2.5x higher conversion rate.
- You have to A/B test creative with QR codes that point to unique landing pages. It’s how you directly track CTV ad engagement and see what’s driving offline actions.
- Work with CTV platforms that have transparent measurement tools. You need solid impression validation and incremental reach analysis to get a real ROAS calculation.
To get more from CTV advertising now that 5G is everywhere, you can’t just run your old linear TV playbook. We proved this with a recent campaign for a national electronics retailer that drove a 3.8x ROAS on online sales and a $12.80 CPL for in-store signups, all by using tight targeting and measurement that finally connects the dots.
Campaign Overview: The “Connected Home” Initiative
Our client, a big electronics retailer with 300+ stores in the US, wanted to push their smart home device line. The main goal was to increase online purchases and also drive foot traffic into stores for product demos by reaching tech-savvy consumers in urban and suburban areas. The campaign ran for a tight eight weeks, from mid-September to mid-November 2026, to get ahead of early holiday shopping.
Budget and Key Performance Indicators
We had a total campaign budget of $850,000. We set some aggressive KPIs based on historicals, but adjusted them for the higher engagement we expected from a focused CTV audience:
- Cost Per Lead (CPL): Under $15 for in-store demo sign-ups.
- Return on Ad Spend (ROAS): 3.5x for online sales directly attributed to CTV.
- Click-Through Rate (CTR): 0.75% for scannable QR codes within ads.
- Impression Volume: 25 million unique impressions.
- Conversions: 5,000 online purchases and 3,000 in-store demo appointments.
- Cost Per Conversion: $170 for online purchases, $283 for in-store demos.
Strategy: Using 5G and Data-Driven Targeting
Our strategy was built on two things: using 5G for better ad experiences and using hyper-local data for targeting. We knew 5G optimization meant more than just faster streams. It let us use interactive ad formats and get way more precise with location targeting.
Audience Segmentation and Targeting
Our target audience was pretty specific: adults 25-54, with household incomes over $75,000, living in designated market areas (DMAs) where 5G was strong. Our targeting approach stacked a few different layers:
- Geographic Targeting: We geo-fenced households within a 5-mile radius of the client’s top 100 retail stores. This was a direct play to get people in the door.
- Behavioral Data: Working with our data providers, we targeted audiences who were already looking at smart home tech and electronics. We bought segments like “Smart Home Enthusiasts” and “Gadget Aficionados.”
- First-Party Data Integration: The client gave us their anonymized CRM data which we onboarded into our demand-side platform (DSP). From there, we built lookalike audiences to find new consumers who behaved just like their best existing customers.
- Contextual Targeting: Ads ran inside relevant shows, think home improvement, tech reviews, and lifestyle programming on platforms like Hulu, Peacock, and various Roku channels.
Stacking our targeting like this let us find really qualified people without wasting the budget.
Creative Approach: Interactive and Action-Oriented
The creative had to show the practical benefits of the smart home gear, not just list features. We ran three main 30-second spots, each focused on a different angle (security, convenience, energy). In the final 10 seconds of each ad, we put a big, dynamic QR code on the screen. When a user scanned it, they hit a mobile-first landing page where they could:
- Schedule an in-store demo at their nearest store.
- Shop product bundles with a special CTV-only discount.
- Sign up for a product newsletter.
Each creative version got its own tagged landing page, so we could track performance down to the individual ad. On some platforms, we also ran interactive overlays that let people click on products right in the video. And this is where 5G’s speed really paid off. The low latency and high bandwidth made the interaction feel instant and smooth.
Execution and What Worked
For execution, we used a mix of programmatic guaranteed and open marketplace buys across the major CTV publishers. We put about 60% of the budget into the guaranteed deals to lock in premium placements and predictable audiences, leaving the other 40% for the open market where we could optimize on the fly.
Strong Performance in Key Metrics
The results were strong across the board:
| Metric | Target | Actual Result | Variance |
|---|---|---|---|
| CPL (In-Store Demo) | Under $15 | $12.80 | 14.7% better |
| ROAS (Online Sales) | 3.5x | 3.8x | 8.6% better |
| CTR (QR Code Scans) | 0.75% | 0.88% | 17.3% better |
| Impression Volume | 25 Million | 27.1 Million | 8.4% over |
| Online Purchases | 5,000 | 5,420 | 8.4% over |
| In-Store Demos | 3,000 | 3,350 | 11.7% over |
| Cost Per Online Purchase | $170 | $156.80 | 7.8% better |
The QR code CTR of 0.88% was even better than we hoped for and proved that people watching CTV are getting comfortable with interactive ads. This QR code setup gave us clear attribution data, tying CTV impressions directly to website visits and sales. According to a recent IAB report, this is a trend that’s only growing. The geo-fencing part of the strategy was a huge win for in-store demos. By focusing on people near the stores, we saw a real lift in foot traffic, which we could confirm by matching ad exposure to anonymized location data from mobile devices. It’s a clear example of how a digital ad can push someone to walk into a physical store.
What Didn’t Work and Optimization Steps
It wasn’t all perfect, though. A few things needed fixing mid-campaign.
Initial Creative Fatigue
About four weeks in, we saw engagement start to dip on two of our three ads. Classic creative fatigue setting in for some audience segments. Optimization: We quickly swapped in two new ads, one with user testimonials and another with a “day in the life” story. The fresh content worked, immediately bumping the CTR back up by 0.15% over the next two weeks. It just shows you absolutely need a pipeline of fresh creative ready to go in any CTV campaign.
Attribution Challenges for Offline Conversions
The QR codes were great for direct attribution, but figuring out the total effect on in-store sales (not just demo sign-ups) was still tricky. A lot of people might see an ad and just go to the store later without scanning anything. Optimization: We ran a matched market test to get a better read. We picked 20 DMAs to be a control group (where we paused the CTV ads for two weeks) and compared their in-store sales to 20 similar test DMAs where the campaign kept running. The analysis wasn’t perfect, but it gave us a solid indicator of incremental lift, suggesting a 7% sales increase in the test markets. This lift analysis gave us a much better picture of the true ROAS.
Ad Frequency Management
Early on, we noticed that ad frequency was getting a little too high in some of the smaller DMAs, which can annoy people. This is a pretty common problem with broad programmatic buys. Optimization: We went back into the DSP and tightened our frequency caps, dropping the max from 5 to 3 impressions per unique user per day. That change helped us keep the brand experience positive without really hurting our reach. We also started testing dynamic creative optimization (DCO) to show different ads to people based on how many times they’d seen one which is another good way to fight fatigue.
| Factor | Target Goal | Actual Result |
|---|---|---|
| Return on Ad Spend (ROAS) | 3.5x | 3.8x |
| Cost Per Lead (CPL) | Under $15 | $12.80 |
| Click-Through Rate (CTR) | 0.75% | 0.88% |
| Online Purchases | 5,000 | 5,420 |
| Impression Volume | 25 Million | 27.1 Million |
| Programmatic Guaranteed Budget | At least 30% | 60% |
The Role of Advanced Connectivity
This campaign’s success was tied directly to better connectivity. The spread of 5G, especially in cities like Atlanta, gave us a few key advantages:
- Higher Quality Streaming: We could be confident our 4K ads were being delivered without buffering, which made for a better viewing experience.
- Faster Interactive Elements: QR code scans and clicks on overlays felt instantaneous which cut down on user friction. An eMarketer report from last year predicted exactly this, and we saw it happen firsthand.
- More Granular Location Data: Better mobile network data, made even better by 5G positioning, gave us much tighter geo-targeting and foot traffic measurement.
Without these tech improvements, the interactive and local parts of our campaign would have been clunky and far less precise.
Conclusion
This “Connected Home” campaign showed that a data-heavy strategy with interactive creative really works for driving both online and offline sales. For our next campaigns, we’re going to use even more interactive formats and work on tightening up our attribution models to get a full picture of the impact.
What is server-side ad insertion (SSAI) and why is it important for CTV?
Server-side ad insertion (SSAI) stitches ads right into the video stream on the server. This is a big deal for CTV because it makes the ads unblockable by most ad blockers and creates a smooth, TV-like experience with no buffering between the show and the commercial. The result? People actually finish watching the ads, which drives up completion rates.
How does 5G specifically enhance CTV advertising capabilities?
5G helps CTV ads in a few ways. It lets you run higher-quality ads (like 4K) without buffering, it makes interactive ads feel instant because of low latency, and it provides more accurate location data for targeting. This all results in a better, more measurable ad experience for everyone involved.
What are programmatic guaranteed deals in CTV and when should they be used?
Programmatic guaranteed deals are basically pre-negotiated deals for specific ad inventory at a fixed price, so you’re guaranteed the impressions. You should use them when you need predictable reach on premium channels, especially for big brand campaigns or product launches where you can’t risk being left out of top-tier shows.
How can advertisers effectively measure the impact of CTV on in-store traffic?
You can measure CTV’s effect on store traffic in a few ways. Use geo-fencing to see if mobile devices that saw your ad later show up in your store. You can also use unique QR codes in the ad that offer an in-store discount. Or, you can run a matched market test, where you compare sales in a market with ads to a similar market without them to figure out the incremental lift.
What challenges can arise with creative fatigue in CTV campaigns and how can they be addressed?
Creative fatigue is just what happens when people see your ad too many times and start tuning it out, so engagement drops. You fight it by having multiple versions of your creative ready to swap in, using dynamic creative optimization (DCO) to automatically show different ads, and keeping a close eye on your frequency caps so you don’t burn out your audience.
