CTV & Audio: 3.5x ROAS in 2026 Campaigns

The digital advertising ecosystem continues its relentless expansion, with particular growth in emerging channels like connected TV (CTV) and digital audio. We’ve seen these platforms mature from experimental playgrounds to essential components of a balanced media mix, demanding sophisticated strategies and precise execution. But how do you truly measure success and build campaigns that resonate in these dynamic environments?

Campaign Teardown: “Sound & Screen” for Aura Home Security

I recently spearheaded a campaign for Aura Home Security, a premium smart home security system. Our objective was clear: increase direct-to-consumer subscriptions for their advanced AI-powered monitoring service. This wasn’t about cheap clicks; it was about driving high-value sign-ups, which meant we needed to reach homeowners with disposable income and a genuine concern for security – a perfect fit for the immersive, brand-building nature of CTV and digital audio.

The traditional digital channels were already saturated. We needed to break through the noise and capture attention where our audience was increasingly spending their leisure time. My team and I identified Roku, Hulu, and Spotify as our primary playgrounds. We knew this wouldn’t be a cheap endeavor, but the potential for higher-quality leads justified the investment.

Strategy: Full-Funnel Immersion

Our strategy, which we internally dubbed “Sound & Screen,” was designed for full-funnel engagement. We didn’t just want awareness; we wanted action. The plan was to use CTV for upper-funnel brand building and consideration, showcasing the product’s sleek design and advanced features with high-quality video. Digital audio would then reinforce the message, often acting as a retargeting mechanism for those exposed to our CTV ads, or as a primary touchpoint for listeners deeply engaged with podcasts or music.

We were particularly keen on leveraging Nielsen’s Q3 2023 Total Audience Report, which highlighted the continuing shift of prime-time viewing to CTV. It underscored that our audience wasn’t just watching TV; they were watching streaming TV. Similarly, the consistent growth in podcast listenership, as detailed by IAB’s 2023 Podcast Advertising Revenue Study, confirmed digital audio’s reach.

Creative Approach: Security, Serenity, Simplicity

For CTV, we produced two 30-second spots and one 15-second cutdown. The 30-second spots focused on storytelling: a family enjoying peace of mind, a package safely delivered, an alert preventing a potential issue. The visuals were crisp, showcasing the Aura app interface and the discreet cameras. The 15-second spot was a direct-response ad, highlighting a limited-time offer. We employed professional voice actors whose tones conveyed trustworthiness and calm.

Digital audio creatives were even more nuanced. We developed three distinct 30-second audio spots. One featured a testimonial from a “satisfied customer” (actor, of course), another used ambient sound effects to evoke a sense of unease quickly followed by the reassuring sound of Aura’s alert, and the third was a straightforward benefits-driven spot. Each ended with a clear call to action and a memorable vanity URL: AuraHome.com/Secure.

Targeting: Precision Over Volume

This is where the campaign truly shined, and frankly, where many campaigns fall short. We didn’t just target “homeowners.” That’s too broad. For CTV, we used a multi-layered approach:

• Demographics: Household income > $100k, ages 35-65.
• Geo-targeting: Single-family home zip codes in suburban areas around Atlanta, specifically focusing on North Fulton County (e.g., Alpharetta, Roswell, Milton) and portions of Cobb County (e.g., Marietta, East Cobb). We even excluded apartment-dense areas like Midtown Atlanta.
• Behavioral: Audiences interested in home improvement, smart home technology, and luxury goods. We also layered in data segments from our DSP partners that indicated recent home purchases or high-value insurance policies.
• Contextual: Placements on news channels, home & garden shows, and family-oriented programming.

For digital audio, we mirrored much of the demographic and behavioral targeting. Crucially, we also targeted specific podcast genres: true crime, financial planning, and parenting. We also implemented a lookalike audience strategy based on our existing customer data, feeding anonymized subscriber lists into our platforms to find similar high-value prospects.

Campaign Metrics & Performance

Campaign: Aura Home Security “Sound & Screen”
Duration: 8 weeks
Budget: $250,000

Our average subscription value was $1,050 (annual plan), so a ROAS of 3.4x meant we were generating $3.40 for every dollar spent. This was a solid win, exceeding our initial goal of 3.0x.

What Worked: Precision and Persistence

1. Granular Geo-Targeting: Focusing on specific, affluent suburban zip codes rather than broad metros significantly improved our conversion rates. We saw a 15% higher CTR in areas like Alpharetta, GA, where the average home value is substantially higher. This was a direct result of our initial market research into the demographics of Aura’s ideal customer.
2. Creative A/B Testing: For CTV, the 30-second storytelling ad outperformed the 15-second direct-response ad in terms of view-through conversions by a factor of 1.5x. For audio, the testimonial spot had a 20% higher listen-through rate and drove more direct website visits than the sound-effects-driven ad. We quickly shifted budget towards the top-performing creatives after the first two weeks.
3. Retargeting Synergy: A significant portion (40%) of our digital audio conversions came from users who had previously been exposed to a CTV ad. This cross-channel retargeting was crucial. We set up an audience segment of users who watched at least 50% of our CTV ads and then served them specific audio ads reinforcing the offer. This is where the magic happens – one channel warms them up, the other closes the deal.
4. Frequency Capping: We were aggressive with our frequency caps, especially on audio (3x per day per user). While some might argue this is too high, for a high-consideration purchase like home security, repeated exposure builds trust and urgency. We monitored ad fatigue closely, but saw no significant drop-off in engagement.

What Didn’t Work (and what we learned)

1. Broad Interest Targeting on CTV: Initially, we included a broader “tech enthusiast” interest group on CTV. This audience segment had a significantly lower conversion rate (0.05%) compared to our more specific home-improvement and security-focused segments (0.32%). We quickly paused this segment after the first week and reallocated its budget, saving us from wasted spend. This is why you always monitor campaign performance metrics closely.
2. Generic Audio CTAs: Our initial audio ads used a generic “Learn More at AuraHome.com.” When we switched to “Visit AuraHome.com/Secure for 20% off your first year,” we saw a 1.8x increase in direct visits from audio. Specificity drives action, especially in audio where visual cues are absent.
3. Attribution Challenges: Honestly, attribution remains the single biggest headache in these channels. While we used a blended model incorporating view-through and listen-through conversions, proving direct incrementality is still an art, not a science. We used a last-touch attribution model for direct reporting but employed a custom multi-touch model for internal optimization, giving partial credit to CTV and audio for assisted conversions. It’s not perfect, but it’s far better than only looking at last-click.

Optimization Steps Taken

Based on our findings, we implemented several key optimizations:

• Dynamic Creative Optimization (DCO): We started testing different CTA overlays on our CTV ads and varying voiceovers for our audio spots based on audience segment. For example, younger audiences received ads with a slightly more modern, upbeat voice, while older demographics heard a more authoritative, calm tone.
• Budget Reallocation: We shifted 20% of the CTV budget from general awareness to retargeting audiences who had engaged with our initial ads but hadn’t converted. We also increased the digital audio budget by 15% due to its superior CPC and ROAS.
• Enhanced Audience Segmentation: We integrated third-party data from a home valuation service to create even more precise audience segments for homeowners with properties valued over $500,000. This was a game-changer for reducing our cost per qualified lead.
• Landing Page Optimization: We created specific landing pages for CTV and digital audio traffic, pre-populating certain fields and offering unique discount codes to track performance more accurately. This allowed us to confirm the efficacy of the vanity URL on audio.

The “Sound & Screen” campaign for Aura Home Security demonstrated that with careful planning, precise targeting, and continuous optimization, connected TV and digital audio are not just brand-building channels, but powerful drivers of direct response and significant ROAS. It’s about understanding the nuances of how people consume media on these platforms and crafting messages that resonate deeply.

My advice? Don’t treat these channels as an afterthought. Invest in quality creative, get surgical with your targeting, and be prepared to iterate constantly. The data will tell you where to go next.
