Open Graph

Action

No Open Graph tags found — social sharing previews will be generic.

FIX

No Open Graph tags found — social sharing previews will be generic.

No Open Graph meta tags found

Without og:title, og:description, and og:image, social media platforms will generate a generic preview when your page is shared.

Why this matters

Without Open Graph tags, social shares show a broken or empty preview card.

Learn more ▾

When someone shares your URL on Facebook, LinkedIn, Slack, iMessage, or any modern chat app, the preview comes from <meta property="og:*"> tags. Without them you get either no card or whatever fragment the social platform guesses — usually unflattering. The four core og: tags (title, description, image, url) cover what every major platform actually reads.

Structured Data

Action

2 JSON-LD block(s) found — issues found that may affect search visibility.

FIX

2 JSON-LD block(s) found — issues found that may affect search visibility.

Malformed JSON-LD block #2

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

Missing or invalid @context in block #1

The @context should be "https://schema.org" for search engines to recognize the data.

Got: http://schema.org/ Expected: https://schema.org

Custom type "School" — unable to validate specific properties

2 JSON-LD blocks found

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

Why this matters

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

Learn more ▾

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.

Source: schema.org / Google Search Central

URL: http://schema.org/

The @context should be "https://schema.org" for search engines to recognize the data.

Expected: https://schema.org

Why this matters

JSON-LD without @context is invalid structured data — Google ignores the entire block.

Learn more ▾

@context must be 'https://schema.org' (or the schema-specific URL). Without it, the block isn't parseable as schema.org JSON-LD and Google skips it. Most schema generators handle this; manual edits sometimes drop the field.
