Use the schema generators to produce clean JSON-LD, then validate before you publish.
Structured data helps search engines understand your pages and can unlock rich results. SEODock includes generators for the most common types, all producing JSON-LD — the format search engines recommend.
Structured data must reflect content that's actually visible on the page. Don't mark up reviews, prices, or FAQs that aren't really there — search engines penalize deceptive markup. See our acceptable use policy for more.
