Sterling Capital’s 2026 AEO Marketing Challenge

The financial services world is conservative, but the pressure to get marketing right is immense. The problem is that quantifying the results of audible experience optimization (AEO) for financial services is a real challenge. Take Sterling Capital, a mid-sized wealth management firm in Chicago. They were pouring money into digital campaigns but their client acquisition had completely stalled. Their marketing director, Eleanor Vance, had a hunch their audio content, everything from podcast ads to how they showed up in voice search, wasn’t pulling its weight, but she didn’t have the data to prove it or figure out what to do next. How do firms like that stop guessing and start actually measuring the impact of their audio marketing?

Eleanor’s problem is incredibly common. So many financial firms throw big budgets at digital marketing, including audio, with no real way to measure the return. Sterling Capital had sponsored a whole series of podcasts about retirement planning and ran targeted audio ads on streaming services. But the old-school metrics like impressions weren’t leading to new client meetings or more assets. “We knew people were hearing us,” Eleanor told me in one of our first meetings, “but we couldn’t tell if they were actually listening, understanding, or, most importantly, acting on it. It felt like shouting into the void sometimes.”

Our first job was to define what “success” even meant for Sterling Capital’s audio spend. For a financial firm, it has to go beyond brand awareness. You need leads, you need appointments booked, and you need asset growth. That demands a much sharper approach than just counting ad plays. We decided to build an AEO analytics framework designed to connect what people heard with what they actually did.

Our initial audit found some big gaps. For instance, their podcast sponsorships had no dedicated landing pages or unique call-to-action (CTA) codes mentioned in the audio. Listeners just heard a generic website address, making it impossible to know if that specific channel was driving any traffic at all. Their voice search strategy was just as basic. The website content wasn’t written for natural language, so when a potential client asked their smart speaker, “What are the best investment strategies for retirement?”, Sterling Capital was nowhere to be found.

This is where you have to look outside your own four walls for data. To get beyond guesswork, we dug into public insights from industry leaders. BlackRock data, for one, provides a ton of information on investor sentiment and digital habits that can directly shape an AEO strategy. A BlackRock Q3 2025 earnings report, for example, showed a 12% year-over-year jump in digital engagement on their platforms, with a big spike in mobile-first interactions. That tells you audio, especially on phones and smart speakers, is a touchpoint you can’t ignore.

We also tore apart reports from the Interactive Advertising Bureau (IAB). A 2025 IAB Audio Advertising Revenue Report showed digital audio ad revenue was still climbing, hitting an estimated $7.5 billion. The report made it clear that programmatic audio and the data needed to personalize ads are becoming central. For Sterling Capital, this was a clear signal to stop using generic messaging and start creating targeted audio ads that would actually connect with specific investor profiles.

The next phase was getting our hands dirty with implementation. For the podcast sponsorships, we gave them unique, trackable URLs and phone numbers to use only in the audio ads. We also got the podcast hosts to include specific, memorable codes that listeners could drop when they called Sterling for a consultation. This finally let Eleanor’s team pin new leads directly to specific audio campaigns. Voice search was a bigger project. We had to figure out how real people ask about financial planning.

By integrating data from the Google Assistant API and Amazon Alexa Skills Kit, we got a much clearer view of user queries. It turns out people were asking long, conversational questions, not the short keywords we’re all used to. Instead of “investment advisor Chicago,” they’d ask, “Who can help me plan for retirement in the Chicago area?” This single distinction changes everything for AEO because it means you need to optimize your site content and build audio answers that directly respond to these more complex questions. We had Sterling Capital develop a library of short, helpful audio snippets for their website that tackled these common financial concerns head-on.

Eleanor was a bit wary at first. “This feels like a lot of moving parts,” she admitted. “How do we make sure it all connects back to our marketing ROI?” It’s the right question to ask. The point of the tech is to drive new client acquisition, period. Our whole approach was built on clear attribution. We built a dashboard that pulled data from their CRM, their website analytics, and all the new audio tracking tools. For the first time, they could see exactly how many consultations came from a podcast code and how many voice searches led to a filled-out contact form, and in the end, how many of those became clients.

One insight from the data was particularly revealing. The audio ads they ran on business news podcasts had a much higher listen-through rate and converted far better than ads on general interest podcasts, even though the general podcasts had more listeners. It proved that for financial services, targeting a smaller, highly engaged audience is far more effective than just chasing reach. We advised them to shift their budget into these niche audio channels where the audience was already primed for financial topics.

We also got a regular A/B testing process going for their audio ad creative. One version might use a direct, authoritative tone, while another took a more empathetic, problem-solution angle. By tracking which ad drove more calls or site visits (using the unique URLs), Sterling Capital could methodically figure out what messaging worked best. This data-driven, iterative loop is what lets you consistently improve audio performance.

Six months after we started, Sterling Capital had a 15% jump in qualified leads that came directly from their audio channels. Even better, their cost per acquisition for these clients dropped by 10%. Eleanor, once hesitant, was now the biggest champion of the program. “We now strategically invest in audio because we know precisely what’s working and why,” she said. “This has completely transformed how we look at our digital strategy.” That level of granular insight is what makes AEO effective instead of just experimental.

Sterling Capital’s story makes one thing perfectly clear for financial services marketing: without hard data and a solid measurement framework, your investment is just a guess. To properly quantify AEO, you have to commit to specific tracking, use external data from sources like BlackRock to inform your bets, and be ready to change things based on performance. It’s about drawing a straight line from the auditory experience to the balance sheet, making sure every single ad and spoken word is helping the firm grow.

The future of financial marketing is happening through the ear. The firms that build sophisticated AEO strategies backed by real data will win the attention of the next generation of investors, who are already using their voice to find information and make decisions. Failing to measure the impact of this shift simply isn’t an option.
