Does schema markup help with AI search and AEO?

Which schema is worth adding

For most service businesses: Organization or LocalBusiness on the home page with consistent name, address and contact details; Service on service pages; Article on blog posts; BreadcrumbList for site structure; and FAQPage where a page genuinely contains questions and answers.

The markup must describe what is actually visible on the page. Marking up content that users cannot see, or adding fake reviews, breaks Google's guidelines.

Keep expectations realistic

Google has narrowed where some rich results appear over the years, so markup will not always change how your listing looks. Its main value now is clarity: it tells crawlers, including the ones that feed AI tools, exactly what your business is and what each page is about.
