No structured data (JSON-LD) found

Adding structured data helps search engines understand your content and can enable rich results.

Why this matters

Without schema.org markup, your pages can't appear as rich results (stars, FAQs, recipes) in search.

Learn more ▾

Structured data is what unlocks rich snippets — review stars, FAQ accordions, recipe cards, breadcrumbs, etc. — that take up more SERP space and dramatically improve click-through. The schema.org vocabulary is well-documented and JSON-LD is the easiest format.

No structured data found

Structured data (JSON-LD) helps search engines understand your content better. Adding it can improve your search result appearance.

Common types include:

WebSite — your site identity and search box
Organization — your company information
Article — blog posts and news articles
Product — e-commerce product pages
BreadcrumbList — navigation paths

Findings

Brand name differs across channels — users see inconsistent identity
Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
No Organization schema — Google can't render your logo in the knowledge panel

How consistently your brand appears across channels — shared link previews, structured data, favicon, contact info.
