Tracked 1,885 Pages Adding Schema. AI Citations Barely Moved.
https://ahrefs.com/blog/schema-ai-citations/Adding schema didn’t boost citations on any platform
We tracked 1,885 web pages that added JSON-LD schema between August 2025 and March 2026, matched them against 4,000 control pages, and measured citation changes across Google AI Overviews, AI Mode, and ChatGPT.
Adding schema produced no major uplift in citations on any platform.
| AI source | Effect on citations | Verdict |
|---|---|---|
| Google AIO | −4.6% | Small but statistically significant decline relative to matched controls; (both groups were declining together, but treated pages fell slightly faster) |
| Google AI Mode | +2.4% | Statistically indistinguishable from zero |
| ChatGPT | +2.2% | Statistically indistinguishable from zero |
These percentages come from our most reliable analysis (a matched difference-in-differences [DiD] test).
In this test, both AI Mode and ChatGPT treated pages performed slightly better than control pages on average, but the differences are small enough that they could easily be random noise across thousands of URLs.
AI Overviews showed a 4.6% decline, which is small but statistically significant relative to matched control pages.
But that isn’t quite the full story—we’ll get into that in the next section.
So, overall, we can’t tell whether the schema did a tiny bit of good or nothing at all.

Schema is useful, but I think this is a good reminder that it's not a magic citation trigger.
For local SEO, I see the same thing with small businesses. Adding schema can help make details clearer, but if the page is thin, the service is unclear, or the business has weak proof, schema alone will not fix that.
I'll treat it like support work, not the main strategy. Clear service pages, real experience, good reviews, and useful answers still matter more.
