"Schema markup" gets thrown around in SEO advice constantly, usually with no real explanation. Here's the plain version.
It's a translation layer, not decoration
Your webpage is written for humans — headlines, paragraphs, buttons. But search engines and AI models don't read the way people do. Schema markup is extra code added to your page that explicitly labels what things are: "this is a business name," "this is a price," "this is a question and this is its answer." It removes the guesswork.
Without it, machines are guessing
A search engine can usually figure out your page is "about" a topic through context. But "usually" and "correctly labeled" are very different levels of confidence — and that gap is exactly where AI models decide whether to trust your page enough to cite it directly in an answer.
What it looks like in practice
Common types include Organization schema (who you are), Service schema (what you offer), Article schema (what you've published, and when), and FAQPage schema (direct question-and-answer pairs an AI model can lift almost verbatim into a response).
Every page Index Nations builds ships with the schema types relevant to that page — not as an SEO add-on, but as part of the page's actual structure from day one.
