Decoding Brand Signals: How AI Systems Interpret Authority Across Industries

Decoding Brand Signals: How AI Systems Interpret Authority Across Industries Here’s the uncomfortable truth: most brands are flying blind when it comes to understanding how generative AI systems see them. They’ve nailed SEO for Google search, tweaked their social algorithms for engagement, and optimised content for every conceivable platform. But ask them how their brand performs in ChatGPT, or whether Google AI Overview even recognises them, and the room goes quiet. My theory? AI visibility is the next authority battleground. And the rules aren’t just new, they’re inconsistent. A brand might dominate in one system while being completely invisible in another. Worse, no one seems to know why. Yet this matters more than most businesses realise because generative AI isn’t just a trend , it’s rewiring how people discover and engage with brands. Here’s what I keep seeing: the way AI platforms evaluate “authority” is nuanced, and it’s not one-size-fits-all. Context matters. Industry matters. The intent behind a query matters. And if you don’t understand how your brand is showing up (or not showing up), you’re already falling behind. Let’s break it down. Is AI Authority the Same Across Industries? Short answer: not even close. In fact, the same prompt can deliver wildly different outcomes depending on the industry you’re in. Our data at Contxt highlights this disparity clearly. Across 2641 AI prompts tested, we’ve seen a staggering 39% divergence rate between ChatGPT and Google AI Overview. That means more than a third of the time, these two systems recommend entirely different brands for the same query. If you’re visible on one but not the other, you’ve got a serious blind spot. Take manufacturing, for instance. In that sector, we’ve tracked brands like Viking Pumps and Red Fern achieving a 100% mention rate across prompts. They’re crushing it. But Iconsys 2, another manufacturing player, only shows up 6.7% of the time . Same industry. Similar verticals. Completely differ
