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[\n {\n \"@context\": \"htt\n\t^...............................\n"

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

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
  • 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.

URL: 70 chars

Titles over 60 characters may be truncated in social sharing previews.

Expected: 25–60 chars
Why this matters

og:title borderline-too-long — Facebook/LinkedIn may truncate. Aim for ~60-70 characters max.

Source: Open Graph Protocol

URL: 204 chars

Descriptions over 200 characters may be truncated in social sharing previews.

Expected: 55–200 chars
Why this matters

og:description borderline-too-long — social platforms truncate around ~200 chars.

Source: Open Graph Protocol

The og:site_name tag displays the website name in social previews.

Why this matters

Without og:site_name, social cards omit the brand attribution — users see the post but not who published it.

Learn more ▾

og:site_name appears in the social card chrome (above the title in Facebook/LinkedIn previews). Without it, posts read as anonymous URLs. Set it to your brand name to get free attribution on every share.
