FIX

Brand Presence

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

53/100

Site name appears as

Page title	Proton: Privacy by default
og:site_name	Proton
twitter:site	—
Organization.name	—

Inconsistent — names differ across channels

Brand assets

Favicon

15/15

covers multiple sizes + apple-touch-icon

Social share image

14/20

og:image set; twitter:image missing

Meta completeness

14/20

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
twitter:card missing
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.

REVIEW

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

Missing or invalid @context in block #1

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

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

Custom type "WebPage" — unable to validate specific properties

URL: https://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.

Missing twitter:card

Without twitter:card, Twitter falls back to Open Graph tags. Adding it gives you more control.

Why this matters

Without twitter:card, Twitter renders posts as plain text — no preview image, no structured layout.

Learn more ▾

Twitter requires `<meta name="twitter:card" content="summary_large_image">` (or summary) to render share-cards at all. Without it, links appear as raw text and engagement plummets vs cards. Twitter also falls back to og:image if twitter:image isn't set, so configure both.
