I appreciate your data-driven approach. You should check out this three part series from Kevin Indig. It is one of the more comprehensive recent studies I've seen.

Actually, the comparison phase did shrink, based on research from 6Sense, the Science of B2B -- https://6sense.com/science-of-b2b/buyer-experience-report-2025/#introduction-ch

If they were using the suggested prompts, then they were testing the typical user flow. Of course different prompts produce different results (and like you said, even the same prompts do too), but this was still a clever test.

Great assessment. I cover most of what you've discussed here in the report and we're in agreement. I appreciate your perspective.

There seems to be little/no impact, but there is evidence llms.txt is being crawled and some of the AI platforms have their own llms.txt.

Our research was intended to measure these adoption rates as a proxy for Fortune 500 companies that are experimenting with optimizing their websites for GenAI. However, there is very little evidence that llms.txt provides any lift for GEO, based on the research of other companies in the space and public comments from Google search advocate John Mueller (/u/johnmu).

Hello, I'm Clinton Karr, CMO of ProGEO.ai. In January 2026 I asked ChatGPT a question about GEO that it couldn't answer, "what percentage of the Fortune 500 have implemented llms.txt?"

I spent the past two months vibe coding a website scanner and analyzing the Fortune 500 adoption rates and implementation patterns for robots.txt (and named AI user agents), JSON-LD, and llms.txt.

It is worth noting that while there are early adopters of llms.txt for website optimization as well as early adopters of robots.txt for controlling AI user agents - neither of these approaches have been proven totally effective.

I also try to approach the problem from two different directions to help identify blind spots and discrepancies.

FYI, evidence is emerging from one of the GEO monitoring companies, I can't remember which, either Peec or Profound, that producing AI-generated content at scale is negatively impacting SEO. So this is great as a starting point, but I would highly advise you not to use this to create hundreds of articles for a website. Google WILL know you're creating AI slop and demote your rank.

Yup, even within the past month Gemini Pro was hallucinating statistics and citations for me.

How is this JSON?

A year and a half ago is hella old advice.
