REVIEW

1 JSON-LD block(s) found — some improvements recommended.

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\":\"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.

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.

REVIEW

Brand Presence

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

C

59/100

Site name appears as

Page title	TU Delft homepage
og:site_name	TU Delft
twitter:site	—
Organization.name	—

Inconsistent — names differ across channels

Brand assets

Favicon

15/15

covers multiple sizes + apple-touch-icon

Social share image

og:image set; twitter:image missing

Meta completeness

20/20

Organization schema

0/15

Contact info discoverable

5/10

contact page

Findings

Brand name differs across channels — users see inconsistent identity
Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
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.

Open Graph tags are well configured for social sharing.

PASS

Open Graph tags are well configured for social sharing.

og:title is short (8 characters)

Ideal length is 25–60 characters for social sharing previews.

Got: 8 chars Expected: 25–60 chars

og:description is long (347 characters)

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

Got: 347 chars Expected: 55–200 chars

Missing og:url

The og:url tag specifies the canonical URL for the shared content.

URL: 8 chars

Ideal length is 25–60 characters for social sharing previews.

Expected: 25–60 chars

Why this matters

og:title very short — may render with awkward whitespace in social cards.

Source: Open Graph Protocol

URL: 347 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:url tag specifies the canonical URL for the shared content.

Why this matters

Without og:url, social platforms infer the canonical URL — often picking a tracking-param variant that pollutes share counts.

Learn more ▾

og:url tells the social platform which URL to count this share against. Without it, platforms use the literal URL the user pasted (which may include utm_* parameters, ref codes, etc.). Setting og:url to the canonical form keeps share-count attribution clean.
