Adding `Schema` Didn't Meaningfully Lift AI Citations

JSON-LD shows a strong correlation with AI-cited pages, but the lift after implementation was tiny. Treat Schema as cleanup for discoverability, not a shortcut for citation growth.

• —Across 1,885 pages, AI-cited URLs were nearly 3x more likely to include JSON-LD; correlation is real, causation is weak.
• —The bigger takeaway is in the headline: adding Schema barely moved citation outcomes, so rollout alone won't change distribution.
• —Schema still makes sense as technical hygiene for content sites, but it should sit behind stronger levers like unique data and clearer page structure.
