You still can’t measure brand strength in AI.

Ashley Faus pointed out this morning on another post that a company is claiming to measure your brand strength/presence in AI.

Unsurprisingly, the claim was not accompanied with a peer-reviewed dataset or methodology, or even a preprint paper.

Let’s review why this is impossible today.

1. Models are trained on different datasets, even within the same family. OpenAI’s o3-mini doesn’t know who Ashley is. GPT-4o does. Saying that “you know what ChatGPT knows about your brand” is an untrue claim, because OpenAI’s own models can’t agree.
2. People don’t use generative AI like they use search. You don’t go into your tool of choice and just type in Katie Robbert or Trust Insights with no other context. You ask things like “Can you find information about Katie Robbert, CEO of Trust Insights?” – and then there are a hundred different ways to word that question, some of which will produce wildly different answers. Olga Andrienko and Tim Soulo highlighted that a few months back when they each posted a snapshot of a query in ChatGPT about who the best SEO software was. Tim’s prompt and Olga’s prompt varied by two tokens, but it was enough to cause different results to appear.
3. Some AI models are grounded in search, like Perplexity or Google Gemini 2 Flash. Others like Anthropic Claude are not. Some can have search turned on, like DeepSeek. You can’t measure the effectiveness of brand search or unbranded search in an apples to apples fashion. Grok 3 is grounded in tweets, so you may have strong brand presence, but it could all be lies.

I get it. Marketers are obsessed with measurement, especially competitive measurement. Our stakeholders want it. But the technical reality of generative AI is that there is no reasonable way to measure it currently. If you’ve seen a peer-reviewed paper and research on this that shows a true, accurate, and effective way to do this, share it in the comments so we can all review it.

Until then, any company making this claim is misleading at best (and may not understand AI), and fraudulent at worst. If they’re asking for your money? They’re definitely lying.

And to be clear, it is not Ashley or her company that is making this claim!
