Schema is the cheapest, most underused lever in modern SEO.

Structured data (usually JSON-LD) embedded in your pages that tells search engines and LLMs exactly what your content is — an article, a product, a how-to, an organisation. It's how machines understand the meaning, not just the words.

Yes — for rich results (FAQ snippets, How-To, Product, Review), for eligibility for AI Overviews and SERP features, and for indexation efficiency on large sites. It rarely moves rankings directly but it shapes how your results appear and how often they're cited.

Yes — and this is underrated. LLMs use structured data to disambiguate entities (your company vs another with a similar name), to extract facts cleanly, and to understand relationships (Person → worksFor → Organization). Schema is foundational for AEO/GEO, not optional.

For most businesses: Organization (or LocalBusiness), Person (for the founder/team), Article (for content), FAQPage (for Q&A blocks), and Service or Product (depending on your offer). I pick the right minimum set per content type — not the maximum.

Yes on all three. Webflow gets template-level JSON-LD in the head; WordPress gets a plugin-free implementation in the theme; headless stacks get a CMS-aware schema layer. The platform decides the technique, not the outcome.

You do. Schema lives in your codebase, validates in your CI, and is documented in an SOP your team uses for new content types. There's no vendor lock-in and no recurring fee — by design.
