REVIEW
1 JSON-LD block(s) found — some improvements recommended.
Critical::
Malformed JSON-LD block #1
JSON parse error: Mismatch type map[string]interface {} with value array "at index 0: mismatched type with value\n\n\t[{\"@context\":\"http://schema.org\"\n\t^...............................\n"

JSON parse error: Mismatch type map[string]interface {} with value array "at index 0: mismatched type with value\n\n\t[{\"@context\":\"http://schema.org\"\n\t^...............................\n"

Why this matters

JSON-LD block fails to parse — Google ignores the entire block, so structured data effectively isn't there.

Common causes: trailing comma, single quotes instead of double, unescaped quote in a string value. Validate at https://validator.schema.org/ or Search Console's Rich Results Test.

Brand Presence

Your brand name differs across channels — visitors see inconsistent identity.

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
  • Only partial contact info discoverable — consider adding a dedicated contact page or mailto/tel link

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

Critical::
og:image is not reachable
The og:image URL could not be fetched. Social platforms won't be able to display it.
Got: https://a.slack-edge.com/737c9d1/marketing/img/homepage/revamped-24/unfurl/hp-revamp-unfurl.en-GB.jpg
URL: https://a.slack-edge.com/737c9d1/marketing/img/homepage/revamped-24/unfurl/hp-revamp-unfurl.en-GB.jpg

The og:image URL could not be fetched. Social platforms won't be able to display it.

Why this matters

An unreachable og:image URL (404, DNS fail, slow timeout) means social platforms cache the failure and serve no image for hours.

Learn more ▾

Social platforms (Facebook, Twitter) cache OG metadata aggressively — including failed image fetches. A momentarily-broken og:image can leave your shares imageless for hours. Test og:image URLs in Facebook's Sharing Debugger to force re-cache after fixing.
