Structured data is one of the clearest signals you can hand both Google and LLMs about what a page actually is. Pick a type, fill in the fields, copy the JSON-LD, and follow the install guide for your stack. Nothing here is sent anywhere. It's all generated in your browser.
Once your JSON-LD looks right, it needs to land somewhere in your page's HTML. Anywhere in
<head> or <body> works, search engines and LLM crawlers parse it
regardless of position. Pick your platform below.
If you skimmed the tool above without fully knowing what any of it does, start here.
Every page you publish has two audiences: the people reading it, and the machines trying to understand it. Schema markup is how you talk directly to the machines. It's a small block of code, written in a format called JSON-LD, that sits inside your page and states facts explicitly. This is an Article. It was written by this person, on this date. This is a Product. It costs this much and is currently in stock.
None of it shows up on the page itself. A visitor never sees it. It exists purely so that Google, Bing, ChatGPT, Perplexity, and everything else that reads your site doesn't have to guess what it's looking at.
For years schema mattered mostly for "rich results," the star ratings, FAQ dropdowns, and breadcrumbs you see in Google search. That's still true. It matters more now because AI systems building an answer from your page have no guarantee they'll correctly parse a stylised heading, a caption, or a claim buried in the third paragraph. Schema removes the guessing. It hands the fact over directly, in a format built to be read by software rather than interpreted by a human eye.
Schema markup is a ranking factor.
RealityGoogle has said directly that it isn't. It doesn't move you up the results page on its own. What it does is make you eligible for rich results and easier for machines to understand, both of which can indirectly help clicks and citations.
More schema always helps.
RealityMarking up types that don't match what's actually on the page, or data that isn't accurate, can trigger a manual action or simply get ignored. Only mark up what's genuinely there.
Adding schema guarantees rich results.
RealityIt's a prerequisite, not a promise. Google still decides whether to show the enhanced listing, and the eligibility criteria change often, without much warning.
Only ecommerce sites need it.
RealityAny content type benefits. A SaaS blog, a job board, a webinar page, an FAQ section: all of them have a schema type built specifically for them.
You need a developer to add it.
RealityFor most sites it's one script tag, pasted once. No build step, no plugin required, no ongoing maintenance unless the underlying content changes.
Schema is only for Google.
RealityAI systems building answers read structured data too. A clearly marked up page is easier to cite correctly, and citation is exactly what GEO is trying to earn.
Valid markup helps AI systems understand a page. It doesn't guarantee they'll cite you over a competitor. The audit checks whether your brand actually shows up in AI Overviews and LLM answers, and gives you a prioritised fix list if it doesn't.
