What Is Cross-Channel Marketing? Audio Is the Missing Link

Finding the right media mix can be difficult. But here's the uncomfortable truth: Your customers don't think about channels, platforms, or budget allocations the way you do. Most of us aren't thinking about which channel we're engaging with—we're thinking about what we're doing, how we're feeling, and what captures our attention in the moment. Maybe we love discovering new music on our commute, or we enjoy listening to a true crime podcast while folding laundry. Consumers follow creators, stories, and experiences, not your media plan.

That's why effective cross-channel marketing isn't about optimizing individual channels in isolation. It's about creating connected brand experiences across the moments and platforms that matter most. As consumers split their attention across streaming audio, social media, video, podcasts, and more, brands face growing challenges around fragmented data, inconsistent measurement, and understanding which touchpoints actually drive results.

Your marketing strategy needs to meet audiences across all of those moments. And that's where audio comes in. Audio reaches consumers during parts of the day when visual channels can't, helping brands create a more connected cross-channel experience while reinforcing messaging across the broader media mix.

What is cross-channel marketing?

Cross-channel marketing creates one ongoing conversation with your audience instead of a dozen disconnected messages across different platforms. Picture this: Someone sees your ad on Instagram. Later that day, they get an email that picks up where the social campaign left off. Then, on their drive home, they hear a podcast ad for the same brand, reinforcing the  same message and nudging them closer to a decision. Each touchpoint feels connected, building on previous interactions rather than competing for attention. That's the core idea behind cross-channel marketing: coordinating messaging, data, and customer experiences across multiple channels to create a more seamless journey.

However, most marketers run into the same problem: Their channels operate in silos. Different teams may run separate campaigns, measure success differently, and use disconnected tools. The result could be wasted ad spend, inconsistent customer experiences, and more. 

Cross-channel marketing helps solve this challenge by connecting audience data and aligning messaging across every touchpoint. Instead of treating social media, email, audio, video, and other channels as separate efforts, brands can create a unified experience that moves customers naturally from awareness to consideration and, ultimately, conversion.

What are the benefits of cross-channel marketing?

More engagement

People don't stick to one platform. They check their email in the morning, scroll social media at lunch, and stream music or a podcast on their evening walk. A brand that shows up in only one of those moments misses the other opportunities to connect. With cross-channel marketing, you can create consistent interactions across multiple touchpoints, building familiarity and driving real engagement.

Enhanced brand perception

Scattered messaging can make brands easy to overlook. Meanwhile, coordinated messaging makes your brand feel intentional. When you show up consistently across channels and experiences, your consumers can develop more positive perceptions. A cohesive cross-channel strategy helps reinforce brand identity, build trust, and create a smoother customer experience from one interaction to the next.

Better marketing ROI and measurement 

When channels operate independently, you risk showing the wrong message to the wrong person at the wrong time. Cross-channel marketing helps reduce risk by making each channel do its job efficiently, only meeting consumers in the right moments. By coordinating efforts across platforms, brands can improve campaign performance, optimize media spend, and gain a clearer understanding of what's driving results.

How does audio fit into a cross-channel strategy?

Cross-channel marketing is about creating a connected customer experience across every touchpoint. Audio plays a unique role because it reaches audiences during moments when other channels often can't.

While video, display, and social media depend on screens, audio accompanies consumers throughout their day—during workouts, household chores, and other activities where visual attention is limited. That makes it a valuable complement to the rest of the media mix, helping brands stay present across more moments in the customer journey.

Reaching audiences during screenless moments

Visual advertising needs a screen. But your customers aren't always looking at one. They're driving, working out, cooking dinner, or walking the dog. Audio fills those gaps—79% of audio consumption happens when visual media formats aren't available. 1 That's time your brand could be present and building familiarity—all while the competition literally can't reach them.

Boosting incremental reach

No single channel reaches everyone. That's why the most effective cross-channel strategies combine multiple formats that work together. Audio can help brands reach consumers who may not be exposed to a campaign through video, display, or social media alone. By adding audio to a broader media mix, marketers can expand audience reach and increase the likelihood that key messages are heard across different environments and devices.

In fact, after analyzing over 100 campaigns, we found that adding video and display ads to an audio-only campaign with SiriusXM Media delivers +52% incremental reach. 2

Building consistency and frequency

Consumers rarely convert after a single interaction. More often, they encounter a brand multiple times across multiple touchpoints before taking action. Audio helps reinforce messaging introduced through channels like CTV, social media, display advertising, and email. When messaging remains consistent across channels, brands can build familiarity and strengthen recall without relying solely on additional visual impressions.

Capitalizing on cross-device usage

Today's listeners use a mix of streaming audio, podcasts, and in-car audio throughout their routines. From mobile phones, to smart speakers, to connected cars—audio moves with them. This continuity makes audio a natural fit within a broader cross-channel marketing strategy. 

What is the difference between cross-channel, omnichannel, and multi-channel marketing?

These terms are often used interchangeably, but they describe different approaches to reaching customers.

Multichannel marketing 

Multichannel marketing means your brand shows up in many places (email, social media, etc.), but those places don't talk to each other. You might run email campaigns, social ads, and podcast spots, but each channel has its own independent operation, messaging, and measurement. 

Cross-channel marketing 

Cross-channel marketing takes the next step by connecting channels and coordinating the customer journey.  Your channels are aligned on messaging, audience data, and campaign goals. Each touchpoint builds on the last, so the customer experience feels connected and cohesive.

Omnichannel marketing 

Rather than focusing on individual channels, omnichannel marketing focuses on creating a seamless brand experience regardless of where or how customers engage. Messaging, data, and customer interactions are unified across channels, devices, and platforms, allowing customers to move between touchpoints without disruption. Whether someone encounters your brand through streaming audio, social media, connected TV, email, or a website, the experience feels consistent and connected.

How audio powers cross-channel campaigns

Audio + search

Search advertising captures demand. But where did that demand come from? In some cases, audio creates it. A listener may hear your ad on a podcast they love and decide to Google your brand later that day. Audio and search work well together: Audio builds awareness and consideration while search converts that interest into action.

Screen fatigue makes this relationship even more powerful. With 58% of streaming audio listeners saying audio content helps them escape from too much visual stimulation, you can tap a listener base that’s looking for a break from visual overload. 3

Audio + social

Podcast hosts aren't just voices—they're trusted figures in their listeners' lives. When you pair podcast advertising with social campaigns, you reinforce your message through people your audience already believes in. When listeners hear a recommendation from a creator they regularly follow, that message can feel more personal and authentic than a traditional ad. 

The connection between audio and social media extends beyond podcasts. Social platforms have become a powerful engine for music discovery, with users finding new songs through TikTok, Instagram, YouTube, and other creator-driven content before heading to streaming audio platforms to listen, save, and share. For brands, that journey creates multiple opportunities to reach audiences as they move between channels.

Many creators also maintain active communities on Instagram, TikTok, YouTube, and other social platforms. Brands can extend their reach by partnering with creators across both audio and social channels, creating a more connected experience for audiences wherever they engage. Whether someone discovers a song on social media before streaming it or hears a trusted podcast host and later sees that creator on Instagram, cross-channel campaigns reinforce your message across multiple touchpoints and reach audiences through voices they already know and trust.

Audio + CTV

CTV is powerful, but it can’t be everywhere your audience is. Audio helps extend the reach of CTV campaigns beyond the living room. Together, the two channels create more opportunities for audiences to encounter and remember your brand.

Video podcasts add another dimension. As podcast audiences increasingly consume content across both audio and video platforms, brands have more opportunities to reach engaged listeners through complementary formats. The result is a cross-channel strategy that follows audiences across devices, platforms, and moments throughout the day.

Ready to close the gap?

If your campaigns feel like they're working hard but not working together, you're not alone. The fix isn't adding more complexity—it's being more intentional about how your channels connect and making sure audio is part of the equation.
