Findings

  • Brand name differs across channels — users see inconsistent identity
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • Consider adding contactPoint — helps appear in "contact us" rich results
  • No discoverable contact info — trust signal is weak, legal risk is higher in regulated regions

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

Info::
Missing recommended property "sameAs" for Organization
Adding "sameAs" can improve how search engines display your content.

Adding "sameAs" can improve how search engines display your content.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Learn more

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.
