Structured data (schema): markup for AI & Google

Structured data · schema.org

In short: Structured data is machine-readable markup added to your page source (in JSON-LD format): it says 'this is a product, this is its price, this is the seller'. Google uses it for rich results (stars, price); AI answer engines trust it to classify the site and cite sources. Missing it doesn't break the page, but lowers the odds machines understand you correctly.

How does a machine 'understand' your site?

To a crawler the page is text — a human reads "Linen Shirt — $45", a machine guesses. Structured data removes the guesswork: {"@type":"Product","name":"...","offers":{"price":"45","priceCurrency":"USD"}} explicitly declares what the page is, its price and its seller. For AI answer engines this declaration is a "safe to cite" signal.

Which types matter?

Organization: on the homepage — company name, logo, contact, social accounts. Like an identity record.
Product + Offer: on every product page — price, stock, currency. The base of rich results and AI product answers.
BreadcrumbList: shows the site hierarchy.
FAQPage: Q&A content — gives answer engines a directly quotable format.
WebSite + SearchAction: if you have site search.

Verify yourself

Three ways: (1) search the page source (Ctrl+U) for application/ld+json; (2) give the URL to validator.schema.org — it lists parsed types; (3) for a product page use search.google.com/test/rich-results — it shows the rich-result eligibility Google actually sees. Our scan looks for these tags on your homepage and product page automatically.

How to add it on Shopify

Most modern Shopify themes already emit basic Product schema on product pages — but missing price/stock fields and absent Organization on the homepage are common. You can add a JSON-LD block to your theme's product.json/main-product.liquid templates or use an app. What matters is the output passing the validator cleanly — markup believed added but broken is better than none yet still faulty.

Frequently asked

Does structured data raise rankings?

It's not a direct ranking factor — but it affects rich-result click-through and machines understanding you correctly; the indirect value is real.

Is it required for AI visibility?

Not mandatory, but one of the strongest signals — if the answer engine can't classify your content, the odds of citation drop.

Are OG tags and JSON-LD the same thing?

Different: Open Graph is for social share cards (og:title, og:image); JSON-LD is for search/AI understanding. Both are needed — our report checks them separately.
