If you’re reading this, you’ve probably noticed that paid media feels like a money pit right now. Your tried-and-true channels don’t work anymore. Those once-fresh creative campaigns feel stale. And thanks to AI-generated summaries and LLMs, your buyers can research you without clicking through (and without leaving a trace in your attribution data).
But there’s still hope. In this episode of Full Steam, Iron Horse principal content strategist Alex Jonathan Brown talks to Iron Horse director of growth marketing Ellen Smolley about the new approaches to paid media that actually get results.
They discuss why comic-strip-style images drive engagement on LinkedIn, how using Clay helped boost audience match rates from 10% to 54%, and why Ellen’s most excited to experiment with mobile billboards ad outside prospects’ offices.


The best channels are where your audience already gathers. For most B2B buyers, that’s increasingly publisher sites.
Ellen shared how she saw results when she shifted budget from display to publisher sites like Demand Gen Report. Along with boosting ad performance, these sites can add credibility to your ads since they’ll appear alongside content that connects more closely to what your audience is seeking out.
That being said, the “best” channel can change as your needs and broader industry trends shift. And before choosing a channel, take the time to first understand your audience, then refine your audience list and intent signals.
For channels where clicks aren’t the goal, measure account-level lift instead of individual response rates.
Ellen shared the example of out-of-home advertising, where attribution is especially difficult. She recommended treating it as a brand awareness play rather than a direct response channel, measuring whether target account engagement lifts across all your channels combined.
Zero-click behavior means your buyers can learn about you before they ever visit your site, which changes what your paid media needs to accomplish.
Smart marketers are shifting some of their budget to AEO to make sure their brand shows up when buyers are doing research on LLMs. They’re also using their paid media toward building familiarity and mind share, versus driving direct response.
