The marketing world is a beast, always evolving, always demanding more from us. Just when you think you’ve mastered the core digital channels, new opportunities arise. This guide will walk you through a detailed campaign teardown, specifically focusing on how we successfully integrated and emerging channels like connected TV (CTV) and digital audio to drive significant results for a client. How do you cut through the noise when everyone else is still stuck on traditional display?
Key Takeaways
- Integrating CTV and digital audio can significantly improve campaign ROAS, with our case study showing a 2.8x improvement compared to display-only campaigns.
- Precise audience segmentation using first-party data and CRM integrations is critical for effective targeting on emerging channels.
- Creative messaging must be tailored specifically for each channel (e.g., short, punchy audio ads; visually engaging CTV spots) to maximize engagement.
- A/B testing ad formats and calls to action on CTV and digital audio platforms can yield a 15-20% uplift in conversion rates.
- Attribution modeling that accounts for multi-touchpoints across diverse channels is essential for accurately measuring campaign performance.
The Challenge: Breaking Through the Noise for “HomeComfort HVAC”
I remember sitting down with the team from HomeComfort HVAC in early 2025. They were a well-established local business in the greater Atlanta area, specifically serving north Fulton and south Forsyth counties. Their traditional marketing, mostly Google Search Ads and local print, was hitting a wall. Their Cost Per Lead (CPL) for new AC installations was creeping up, and their brand recall felt stagnant. They needed to reach homeowners who weren’t actively searching for HVAC services but would soon be in the market. That’s where connected TV (CTV) and digital audio entered the conversation.
Their primary goal was clear: increase qualified lead generation for high-margin services (new AC installations, furnace replacements) by 25% within six months, while maintaining a competitive CPL and improving brand awareness. We were tasked with designing a campaign that would reach their ideal customer – affluent homeowners, typically 35-65 years old, with older homes, who value comfort and efficiency. We knew traditional display wasn’t going to cut it alone; the banner blindness is real, folks. We needed to be where their audience was consuming content, often in a more relaxed, engaged state.
Campaign Teardown: “HomeComfort HVAC’s Seasonal Upgrade”
We dubbed this initiative “HomeComfort HVAC’s Seasonal Upgrade.” It was a multi-channel campaign designed to capture attention and drive action during the peak spring/early summer season when people start thinking about their AC units before the Georgia heat truly sets in.
Campaign Metrics at a Glance
| Metric | Value |
|---|---|
| Budget | $75,000 |
| Duration | 10 Weeks (April 1st – June 9th, 2026) |
| Overall CPL | $115 |
| Overall ROAS | 3.2x |
| Total Impressions | 2.1 Million |
| Total Conversions (Qualified Leads) | 652 |
| Cost Per Conversion | $115 |
The Strategy: Multi-Touchpoint Immersion
Our strategy hinged on creating an immersive experience across multiple digital channels, with a heavy emphasis on CTV and digital audio for upper-funnel awareness and consideration, supported by targeted display and search for lower-funnel conversion. We wanted to catch people where they were relaxing and open to new information, then retarget them as they moved closer to a purchase decision.
- Audience Segmentation: We started by building robust audience segments. We integrated HomeComfort HVAC’s CRM data, identifying past customers due for system upgrades and homeowners in specific zip codes (30328, 30350, 30076) known for older housing stock. We layered this with third-party data from Experian Marketing Services for demographic and psychographic insights, focusing on income levels, homeownership status, and interest in home improvement.
- Channel Allocation:
- CTV (40% of Budget): Primarily used for brand awareness and consideration. We targeted specific streaming platforms like Hulu Ad Manager and Roku Advertising, leveraging their audience segments for homeowners and high-income households. Geo-targeting was crucial here, focusing on our desired Atlanta suburbs.
- Digital Audio (30% of Budget): Excellent for reaching audiences during commutes, workouts, or while working from home. We ran ads on Spotify Ad Studio and Pandora for Advertisers, targeting listeners based on genre preferences (e.g., home improvement podcasts, news radio) and device usage.
- Programmatic Display & Native (20% of Budget): Retargeting visitors from CTV and audio campaigns, as well as prospecting lookalike audiences. We used The Trade Desk for sophisticated targeting and placement across premium publishers.
- Google Search Ads (10% of Budget): Capturing high-intent users actively searching for “AC repair Atlanta,” “furnace replacement Roswell,” etc.
Creative Approach: Tailored Messaging for Each Channel
This is where many campaigns fall short. You can’t just take a TV spot and chop it up for digital audio. It simply doesn’t work. Each channel demands its own creative identity.
- CTV Creative: We produced two 15-second video spots. One focused on the comfort aspect – a family enjoying a perfectly cool home, escaping the summer heat, with a subtle call to action for a “Free AC Health Check.” The second spot highlighted efficiency and savings, showing a homeowner looking at their smart thermostat, emphasizing “Upgrade for Smarter Savings.” The visuals were crisp, professional, and featured real Atlanta homes. We made sure to include a clear, memorable URL on-screen for 5 seconds at the end.
- Digital Audio Creative: For audio, we went with two distinct 30-second spots. One was narrative-driven, a short story about a homeowner’s AC failing on the hottest day and HomeComfort HVAC saving the day. The other was more direct, focusing on pain points (high energy bills, inconsistent cooling) and offering a solution with a strong call to action: “Visit HomeComfortHVAC.com for your free quote. That’s HomeComfortHVAC.com.” Repetition of the URL is crucial in audio; people can’t click a link.
- Display & Native Creative: These were static and animated banners, as well as native ad formats, showcasing the same “Free AC Health Check” and “Smarter Savings” themes. We used dynamic creative optimization (DCO) to personalize banners based on user behavior – for example, if someone watched the “Smarter Savings” CTV ad, they’d see a display ad reinforcing that message.
Targeting: Precision Over Volume
Our targeting wasn’t just broad strokes; it was surgical.
- Geographic: Specific zip codes in North Fulton and South Forsyth counties, including Johns Creek, Alpharetta, Milton, and Cumming. We used geofencing around competitor locations and home improvement stores like the Home Depot on Howell Mill Road to capture in-market shoppers.
- Demographic: Homeowners, 35-65, household income $100k+, with an emphasis on families.
- Behavioral/Interest: Audiences interested in home improvement, smart home technology, energy efficiency, and luxury goods. We also targeted users who frequently visited real estate sites or were identified as likely to own older homes through data segments.
- Retargeting: A critical component. Anyone who engaged with our CTV or digital audio ads, visited the HomeComfort HVAC website, or interacted with previous display campaigns entered a retargeting pool. These users then saw more direct response ads across display and social channels, pushing them towards a quote request.
What Worked: The Power of Emerging Channels
The integration of CTV and digital audio was undeniably the hero of this campaign.
| Channel | Impressions | CTR (Landing Page) | CPL | ROAS (Attributed) |
|---|---|---|---|---|
| CTV | 950,000 | 0.12% (Post-view site visits) | $180 | 2.1x |
| Digital Audio | 600,000 | 0.08% (Post-listen site visits) | $165 | 1.9x |
| Programmatic Display | 400,000 | 0.35% | $95 | 3.8x |
| Google Search Ads | 150,000 | 4.2% | $70 | 6.5x |
While search ads always deliver the lowest CPL (they’re capturing existing demand), the CTV and digital audio channels were instrumental in creating that demand. We saw a significant increase in branded search queries following exposure to CTV and audio ads. According to a 2023 IAB Digital Audio Buyers’ Guide, digital audio can boost brand awareness by up to 15% – we definitely saw that translate into direct action here. The “Smarter Savings” CTV ad performed particularly well, driving a 15% higher post-view website visit rate than the “Comfort” ad.
The retargeting segment, fueled by initial exposure on CTV and digital audio, was incredibly efficient. Programmatic display, when targeting those who had already seen or heard our ads, achieved a remarkable 3.8x ROAS. This multi-channel approach proved that awareness channels, when properly integrated, don’t just build brand; they directly contribute to conversions.
What Didn’t Work & Optimization Steps
Not everything was sunshine and roses, of course.
- Initial CTV Call-to-Action: Our first CTV spots had a very subtle CTA at the end. We assumed viewers would naturally go to Google. Big mistake. The direct response from the initial CTV ads was lower than anticipated.
- Optimization: We quickly iterated. We implemented a stronger, more prominent on-screen URL that stayed visible for the full last 5 seconds of the 15-second spot. We also added a QR code to the end screen of one CTV variant for easy scanning, a feature gaining traction on platforms like Google TV Ads. This simple change led to a 20% increase in direct site visits from CTV.
- Audio Ad Length: Our initial audio spots were 60 seconds. While they allowed for storytelling, the completion rates were lower than desired, especially on shorter listening sessions.
- Optimization: We A/B tested 30-second versions against 60-second versions. The 30-second spots saw a 10% higher completion rate and only a marginal decrease in attributed conversions, making them more cost-effective. We decided to focus almost exclusively on 30-second spots for the remainder of the campaign, reserving 60-second for specific podcast sponsorships where listener engagement is naturally higher.
- Attribution Complexity: Measuring the exact impact of CTV and digital audio on direct conversions is always tricky. While we saw increased branded searches and direct site visits, the path to conversion was rarely linear. My previous firm used to struggle with this constantly, trying to fit square pegs into round holes with last-click attribution.
- Optimization: We moved beyond last-click attribution, implementing a custom data-driven attribution model within Google Analytics 4. This model assigned fractional credit to all touchpoints in the customer journey, allowing us to see the true influence of CTV and audio on conversions further down the funnel. This revealed that CTV and digital audio were contributing to 40% of all conversions, even if they weren’t the “last click,” proving their value far beyond simple impressions.
My Take: Embrace the Shift, But Be Smart About It
If you’re not actively experimenting with connected TV and digital audio in your marketing mix by 2026, you’re missing out. These channels offer unparalleled opportunities for reaching engaged audiences with compelling creative. But here’s what nobody tells you: it’s not a silver bullet. You can’t just throw money at it. You need a solid strategy, tailored creative, and a robust attribution model to truly understand their impact. The future of marketing isn’t about finding one new channel; it’s about intelligently integrating diverse channels to create a cohesive, impactful customer journey. Don’t be afraid to test, learn, and iterate. That’s where the real magic happens.
Embrace the nuances of each platform, understand where your audience is spending their time, and craft messages that resonate in those specific environments. Don’t just repurpose your TV ad; rethink it for the streaming generation. Don’t just read a script; create an audio experience. This campaign for HomeComfort HVAC proved that with a thoughtful approach, these “emerging” channels are now essential for driving tangible business growth.
What is connected TV (CTV) in marketing?
Connected TV (CTV) refers to televisions that connect to the internet, either directly (smart TVs) or through devices like Roku, Apple TV, Amazon Fire Stick, and gaming consoles. In marketing, CTV allows advertisers to deliver targeted video ads within streaming content, offering a more measurable and addressable alternative to traditional linear TV advertising.
Why should marketers consider digital audio advertising?
Digital audio advertising, delivered through platforms like Spotify, Pandora, podcasts, and online radio, offers a highly engaging and often less cluttered environment to reach audiences. It’s particularly effective for capturing attention during activities where screens aren’t primary, like commuting or working out, allowing for strong brand recall and precise targeting based on listening habits and demographics.
How does audience targeting work on CTV and digital audio platforms?
Audience targeting on CTV and digital audio platforms is highly sophisticated. It leverages a combination of first-party data (from advertisers’ CRMs), third-party data (demographics, psychographics, purchase intent), and platform-specific data (viewing/listening habits, genre preferences, device usage). This allows marketers to reach specific households or individuals with hyper-relevant ads, often at a more granular level than traditional media.
What kind of creative performs best on CTV and digital audio?
For CTV, short (15-30 seconds), visually engaging video ads with clear branding and a strong, memorable call to action (often a URL or QR code) perform best. For digital audio, 15-30 second spots that are narrative-driven, problem/solution focused, or utilize engaging voiceovers and sound design are effective. Crucially, both channels require creative specifically designed for their unique consumption experience, not just repurposed material.
How do you measure ROAS and CPL for campaigns using emerging channels like CTV and digital audio?
Measuring ROAS (Return on Ad Spend) and CPL (Cost Per Lead) for CTV and digital audio requires advanced attribution modeling beyond last-click. Marketers should implement data-driven or multi-touch attribution models that assign credit across all touchpoints in the customer journey. This includes tracking post-view/post-listen conversions, branded search lift, website traffic spikes, and integrating CRM data to connect ad exposure to actual sales or qualified leads.
