Join the WaitlistSchema markup is structured data — a machine-readable description of your page using the schema.org vocabulary. Search engines use it to power rich results: star ratings, FAQ dropdowns, product prices, event dates, recipe cards, video thumbnails. AI answer engines lean on it even harder, because structured data is the cheapest way for a model to be certain about facts like price, availability, dates and authorship.
Pages with rich results consistently earn higher click-through rates than plain blue links at the same position. Schema is not a magic ranking switch — it is an eligibility switch. Without it, Google will not even consider your page for most rich result types.
Google's documentation recommends JSON-LD: a single <script> block, separate from your visible HTML, that you can add, template, and debug without touching your markup. Microdata scatters attributes across dozens of tags and breaks the moment a designer moves a div. Every output from this tool is clean, pretty-printed JSON-LD.
<head> of the page it describes.Golden rule: the markup must describe content actually visible on the page. Marking up reviews, FAQs, or prices that visitors cannot see violates Google's guidelines and can earn a manual action.

Schema markup is structured data added to a web page that describes its content in a machine-readable vocabulary (schema.org). Search engines and AI assistants use it to understand what a page is about and to display rich results like star ratings, FAQ dropdowns, event details, and product prices.
Schema markup is not a direct ranking factor, but it makes pages eligible for rich results, which typically earn higher click-through rates than plain listings. It also helps AI search engines cite your content accurately. More qualified clicks and better understanding generally compound into stronger organic performance.
Use JSON-LD. It is Google's recommended format because it lives in a single script tag instead of being woven through your HTML attributes, which makes it easier to add, maintain, and debug. This generator outputs JSON-LD only.
Paste the generated script tag anywhere inside the head or body of the page it describes — head is conventional. The markup must describe content actually visible on that page; do not mark up content that is not there.
Use Google's Rich Results Test to check rich-result eligibility and the Schema.org validator for general syntax. After deploying, monitor Search Console's enhancement reports for errors and impressions.
