How an RMN's tech stack impacts your advertising results

In this episode, I dive deep into why the technology stack behind these networks isn’t just a backend concern—it’s the backbone of your campaign outcomes. From ad server speeds to reporting capabilities and everything in between, we’ll look at why brands and advertisers need to get curious (and even demanding) about the RMNs they partner with.

I’ll share how platforms like Amazon and Walmart dominate with vertically integrated stacks and what that means for the rest of the market. I also explore what retailers’ tech decisions mean for advertisers and offer some essential questions you should ask any RMN partner before signing on. If you’re trying to make smarter ad investments and maximize ROI in the evolving RMN space, this episode is for you.
