Everyone says schema markup = more AI citations. Ahrefs tested 2,000 pages and found… nothing. Correlation was never causation 👀 What do you actually think moves the needle? #GEO #AISearch #StructuredData #SEO2026
If you've been following GEO advice on how to rank an AI search, you definitely heard about the importance of structured data or schema markup. I think it's safe to say this is the most commonly repeated piece of advice for ranking an AI. If you want AI to notice you, you need to have structured data or schema markup on your pages. Most of the time, people making these LinkedIn posts or TikTok videos had no data to support this claim, but occasionally they would point to the fact that pages cited by AI are much more likely to have structured data on them. And that seems like proof, right? Well, recently Ahrefs called BS on that. They just published, as far as I know, the first large scale study to figure out if structured data has any impact on AI citation rate.

Ahrefs' blog post provides a lot more data and information, including why they think there might be a slight negative correlation in AI overviews. Their methodology is really impressive, but for those of us that have actually been doing the work and running the experiments, this was no surprise. The truth is, if structured data actually made AI cite your pages more often, it would be really easy to prove, and there are a lot of incentives for people selling these services to prove it. Of course, that data has ye...
