What is JSON-LD?
The preferred structured-data format: a script block describing page entities without touching visible markup. One @graph can carry Organization, WebSite, Article, FAQ, and Breadcrumb nodes together.

Schema Markup
Structured-data vocabulary (schema.org) describing page entities so engines can disambiguate them. JSON-LD is the preferred format; markup must mirror visible content.
Rich Result
An enhanced search result with extra visuals or data: stars, FAQs, images, prices. Eligibility comes from valid structured data plus page quality; markup alone never guarantees display.
FAQPage Schema
Structured data marking visible on-page Q&A pairs. Only mark questions with visible answers; hidden-answer FAQ markup is a spam risk, not a shortcut.
Technical SEO
The crawling, indexing, rendering, and performance work that lets search engines reach, understand, and serve your pages. It covers directives, architecture, speed, and structured data rather than words on the page.
Crawling
How search-engine bots discover pages by following links, sitemaps, and directives. If a URL is never crawled, it cannot be indexed no matter how good its content is.
Crawl Budget
The number of pages a search engine will crawl on a site in a given period, driven by server capacity and demand signals. Large or slow sites must spend it on indexable, valuable URLs.
