Frequently Asked Questions
What is structured data?
Structured data is code (usually JSON-LD) added to your HTML that explicitly tells search engines about your content's meaning. It enables rich results (star ratings, FAQ dropdowns, recipe cards, event listings) that stand out in search results.
Which structured data types trigger rich results?
Common rich result types: FAQ, HowTo, Product, Recipe, Review, Event, JobPosting, LocalBusiness, Article, Breadcrumb, Video, and Course. Google continuously adds new types - check the Search Gallery for current eligibility.
Does structured data improve rankings?
Structured data doesn't directly boost rankings, but rich results significantly increase click-through rates (20-30% higher). Higher CTR leads to more traffic and can indirectly improve rankings through positive engagement signals.
