Google data weakens claims that schema drives AI citations

Agencies selling schema as a fast lane to AI visibility just lost a lot of their pitch. Google now says FAQ rich results are no longer appearing in Search, and Ahrefs found no major citation lift after tracking 1,885 pages that added JSON-LD schema and comparing them with 4,000 control pages across Google AI Overviews, AI Mode and ChatGPT.

The Google side of the story is moving in one direction: narrower rewards and tighter eligibility. Google first cut back FAQ rich results in August 2023, limiting them to well-known, authoritative government and health sites and reducing HowTo visibility at the same time. Its current structured-data guidance says markup helps Google understand page content and can make a page eligible for a richer appearance, but it does not guarantee that any rich result will show. Google also says a structured-data manual action affects eligibility for rich results, not web-search ranking.

That matters because the visible payoff for markup has been shrinking, not expanding. Google’s FAQPage documentation now limits eligibility to authoritative government-focused or health-focused sites, and its documentation says FAQ rich results are no longer appearing in Search. Google plans to drop the FAQ search appearance, the FAQ rich result report and Rich Results Test support in June 2026, with Search Console API support following in August 2026. Google Search Central’s updates page now includes that deprecation in its May 2026 documentation updates.

Ahrefs’ numbers undercut the other half of the sales pitch, the idea that schema directly buys you more mentions inside AI answers. The study followed pages that added JSON-LD between August 2025 and March 2026 and found no major uplift in citations across Google AI Overviews, AI Mode or ChatGPT. That does not make schema useless. It does make the promise around it much smaller.

The practical takeaway for SEO teams is straightforward: use schema where it improves machine readability, page structure and content clarity, but stop treating it like a magic visibility lever. Google still says structured data can help it understand title text, images and date information, which makes it an organization tool first. In a market where clients hear “schema” and expect instant gains, the harder sell is also the honest one: markup can help a page make sense to systems, but it does not guarantee prominence, authority or citations.
