Unlock CTV & Audio: Boost ROI 25% with Our 5 Steps

The marketing world is buzzing with the incredible potential of emerging channels like Connected TV (CTV) and digital audio. These platforms offer unparalleled reach and targeting precision, fundamentally reshaping how brands connect with their audiences. But how do you actually run successful campaigns here, and what does it take to truly stand out? This guide will walk you through the practical steps, backed by real-world examples, to master these powerful new frontiers.

1. Understand the Landscape: Why CTV and Digital Audio Matter Now

Before we even think about setting up a campaign, you need to grasp the seismic shift happening in media consumption. People aren’t just cutting the cord; they’re embracing a universe of on-demand, personalized content. According to a Nielsen report from Q1 2025, CTV viewership now accounts for over 50% of total TV viewing minutes among 18-49 year olds, a staggering increase from just a few years ago. Similarly, digital audio, encompassing podcasts, streaming music, and internet radio, has exploded. IAB’s 2025 Digital Audio Advertising Report highlighted a 22% year-over-year growth in ad spend, reaching over $12 billion. If your audience is watching TV or listening to music and podcasts, they’re likely doing it through these channels. Ignoring them means missing a massive chunk of potential customers.

I’ve seen too many brands cling to traditional linear TV or display advertising, wondering why their reach is dwindling. We had a client, a regional credit union based out of Dunwoody, Georgia, who was heavily invested in local cable spots. Their reach was flatlining. We shifted 30% of their video budget to CTV, targeting specific zip codes around their branches and leveraging household income data. The results were immediate: a 15% increase in website traffic from those areas and a 7% uptick in new account inquiries within the first quarter. It’s not magic; it’s just understanding where the eyeballs and eardrums are.

Pro Tip: Don’t just chase impressions. Focus on attention metrics. For CTV, consider completion rates. For digital audio, look at listen-through rates. These tell you if your message is actually resonating, not just being served.

Common Mistake: Treating CTV like linear TV or digital audio like traditional radio. The targeting capabilities are vastly different, and your creative strategy needs to reflect that. You can’t just repurpose old assets and expect success.

2. Crafting Your Cross-Channel Strategy and Budget Allocation

A successful campaign isn’t just about picking a channel; it’s about how those channels work together. I always advocate for an integrated approach where CTV and digital audio complement your other digital efforts. Think about the user journey: someone might hear your ad on a podcast during their commute, then see your video ad on their smart TV later that evening. This multi-touchpoint strategy builds frequency and recall.

For budget allocation, I typically recommend starting with 15-20% of your total digital media budget dedicated to CTV and digital audio combined, especially if you’re new to these channels. This allows for meaningful testing and optimization without overcommitting. As you see results, you can scale up. Within that 15-20%, a 60/40 split favoring CTV for video-centric brands or a 50/50 split for brands with strong audio messaging often works well. This isn’t a hard rule, of course; it depends on your specific goals and audience.

When planning, consider the platforms. For CTV, you’ll be looking at Demand-Side Platforms (DSPs) that integrate with major streaming services. Think The Trade Desk, Magnite (formerly Rubicon Project and Telaria), and Google Display & Video 360 (DV360). For digital audio, DSPs like The Trade Desk and DV360 also offer robust audio capabilities, alongside specialized platforms like Spotify Ad Studio for direct buys on Spotify, and various podcast networks. The key here is to choose platforms that offer strong measurement and attribution features.

3. Developing Tailored Creative Assets That Resonate

This is where many campaigns fall short. You can have the best targeting in the world, but if your creative is bland or mismatched, you’re just wasting money. I’m a firm believer that creative is king, especially in these emerging channels where user attention is fleeting and expectations are high.

For CTV, think short, impactful, and high-quality video.

• Length: 15-30 seconds is ideal. Longer spots can work, but you risk audience fatigue.
• Quality: This isn’t YouTube pre-roll from 2018. We’re talking broadcast-quality video, often 1080p or 4K. Your ad will be on a big screen, so pixelation or poor production values are immediately noticeable.
• Call to Action (CTA): Make it clear and concise. Since users can’t click directly on a TV screen, drive them to a memorable URL, a QR code (yes, they’re back!), or a specific search term.
• Sound Design: Critical! Many people watch CTV with sound on. Don’t rely solely on visuals.

For digital audio, the medium is entirely different.

• Length: 15-60 seconds. Podcasts often accommodate longer spots (30-60s), while streaming radio might favor shorter (15-30s).
• Clarity: Your message must be understood with sound alone. Avoid complex concepts or visuals-dependent narratives.
• Voice Talent: Invest in professional voice actors. A poor voice can undermine your entire message.
• Soundscaping: Use sound effects and music to create atmosphere and reinforce your brand.
• CTA: Again, clear and memorable. A unique URL or a specific, easy-to-remember phrase is essential, as listeners are often multitasking.

Example Creative Strategy: We recently worked with a direct-to-consumer meal kit delivery service. For CTV, we produced a vibrant 15-second spot showcasing delicious, easy-to-prepare meals, ending with a compelling offer and a QR code for quick scanning. For digital audio, we created a 30-second narrative ad featuring a busy parent talking about the convenience and quality of the meals, with a strong emphasis on a unique discount code mentioned twice. This dual approach ensured the brand message was delivered effectively across both visual and auditory contexts.

Pro Tip: A/B test your creative relentlessly. Run at least three different versions of your CTV spots and audio ads simultaneously to see which performs best. Subtle changes in messaging, music, or even voiceover can yield significant differences in engagement.

4. Precision Targeting: Reaching the Right Audience

This is where CTV and digital audio truly shine compared to their traditional counterparts. Gone are the days of broad demographic targeting; we can now get incredibly granular. When I’m setting up campaigns, I focus on a layered approach to audience segmentation.

First-Party Data: This is your gold mine. Upload your customer lists, website visitors, and CRM data into your DSP. Platforms like The Trade Desk allow for secure data onboarding, enabling you to target existing customers with upsell offers or create lookalike audiences based on your best customers. If you’re not collecting first-party data effectively, you’re leaving money on the table. Start now.

Third-Party Data: Augment your first-party data with segments from providers like Experian Marketing Services or Oracle Advertising and Customer Experience (CX). These can include behavioral data (e.g., “avid runners,” “luxury car enthusiasts”), psychographic data (e.g., “environmentally conscious consumers”), and even purchase intent signals. Be selective here; not all third-party data is created equal.

Contextual Targeting: For digital audio, especially podcasts, contextual targeting is powerful. Placing your ad within a podcast about personal finance for a financial planning service is incredibly effective. Many DSPs offer categories and keywords to help match your ads to relevant content. For CTV, this might mean targeting specific genres of shows or even individual programs where your audience is likely to be watching.

Geographic Targeting: Beyond basic city or state targeting, you can get down to specific zip codes, Designated Market Areas (DMAs), or even radius targeting around physical locations. For our Dunwoody credit union client, we specifically targeted zip codes 30338 and 30346 around their branches, combined with household income filters to reach their ideal customer. This hyper-local approach drastically reduces wasted impressions.

Screenshot Description: Imagine a screenshot from The Trade Desk’s audience builder interface. On the left, you’d see selectable categories like “First-Party Data,” “Third-Party Data Providers,” and “Demographics.” In the main window, you’d see various segments stacked: “Upload Customer List (hashed emails)” + “Experian: High Net Worth Individuals” + “Contextual: Business News Podcasts” + “Geo: Atlanta DMA, excluding Fulton County.” This visual layering is how you build precise audiences.

Common Mistake: Over-segmenting your audience. While precision is good, if your segments become too narrow, you might limit your reach and drive up CPMs unnecessarily. Find the sweet spot between specificity and scale.

5. Launching and Optimizing Your Campaigns

Once your strategy is set, creative is ready, and audiences are defined, it’s time to launch. This isn’t a “set it and forget it” process. Active monitoring and optimization are non-negotiable.

5.1. Setting Up Your Campaign in a DSP

Let’s use The Trade Desk as an example, as it’s a leading platform for both CTV and digital audio.

1. Create a New Campaign: Navigate to “Campaigns” -> “Create New Campaign.”
2. Define Campaign Goals: Select “Brand Awareness,” “Traffic,” “Conversions,” etc. This guides the platform’s bidding algorithms.
3. Set Flight Dates and Budget: Clearly define your start/end dates and daily/total budget. I always recommend a slightly higher daily budget initially to allow the algorithm to learn faster.
4. Create Ad Groups/Line Items: Separate your CTV and digital audio efforts into distinct ad groups. This allows for independent budgeting, targeting, and reporting.
5. Audience Targeting: Apply the layered audience segments you built in Step 4.
6. Inventory Selection: For CTV, specify inventory sources like Hulu, Peacock, Roku. For digital audio, select publishers like Spotify, Pandora, and podcast networks.
7. Upload Creative: Upload your tailored video and audio assets. Ensure they meet platform specifications (e.g., file type, resolution, length).
8. Bidding Strategy: Start with an automated bidding strategy optimized for your campaign goal (e.g., “Maximize Conversions” or “Target CPM”). Adjust manually only after you have sufficient data.

5.2. Monitoring and Optimization

Once live, closely monitor your campaign performance.

• Daily Check-ins: For the first few days, I’m checking performance daily. Look at impression volume, spend pace, completion rates (CTV), listen-through rates (audio), and click-through rates (if applicable).
• Frequency Capping: This is crucial. Excessive frequency can lead to ad fatigue and wasted spend. For CTV, I often start with a cap of 3-4 impressions per user per week. For audio, 2-3 per day might be more appropriate, depending on the platform. Adjust based on performance and user feedback.
• Creative Performance: Identify which creative assets are performing best. Pause underperforming ones and allocate budget to the winners. Consider refreshing creative every 4-6 weeks to prevent fatigue.
• Audience Refinement: If certain audience segments aren’t converting, pause them. If a particular segment is overperforming, create lookalikes or expand similar segments.
• Placement Optimization: Exclude low-performing publishers or apps. If you see high fraud rates on specific inventory sources, block them immediately.

Case Study: SaaS Company Customer Acquisition

A B2B SaaS client, targeting small business owners, decided to experiment with CTV and digital audio in Q3 2025. Their primary goal was to drive free trial sign-ups. We allocated 18% of their digital ad spend to these channels, split 70% CTV / 30% digital audio. We used DV360 for execution.

Campaign Setup:

• CTV: 15-second animated explainer video. Targeted small business owners (third-party data from Experian) watching business news and productivity shows on Hulu and Peacock. Frequency cap: 3/week.
• Digital Audio: 30-second testimonial-style audio ad. Targeted listeners of business podcasts and entrepreneurship-focused streaming radio. Frequency cap: 2/day.

Results (over 8 weeks):

• CTV: Achieved a 92% video completion rate. Drove 60% of all new trial sign-ups from the campaign. Cost-per-trial was $42, significantly lower than their previous display benchmarks of $65.
• Digital Audio: Achieved an 88% listen-through rate. Contributed 40% of new trial sign-ups. Cost-per-trial was $58, still competitive.

The success here wasn’t just about the channels; it was the iterative optimization. We initially had a 30-second CTV ad, but testing showed the 15-second version had a 10% higher completion rate and better recall, so we shifted budget accordingly. For audio, we found that focusing on specific podcast genres yielded much better results than broad streaming radio. This granular approach, driven by real-time data, made all the difference.

Pro Tip: Don’t just look at last-click attribution. Utilize impression-based attribution models or even multi-touch attribution (if your DSP supports it) to understand the full impact of these channels, especially for brand awareness and upper-funnel activities. These channels are fantastic for building brand familiarity that pays off later.

The future of marketing is undeniably intertwined with these dynamic channels. Ignoring them isn’t an option; mastering them is a necessity for any brand looking to connect deeply and meaningfully with their audience. By following these steps and committing to continuous learning and optimization, you’ll be well on your way to unlocking their full potential.
