Brand Presence

Partial brand coverage — a few channels are missing brand signals.

Findings

  • Missing brand name in: og:site_name, twitter:site, Organization.name
  • 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.
Warning::
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
Info::
Missing recommended property "description" for WebSite
Adding "description" can improve how search engines display your content.
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.

Adding "description" can improve how search engines display your content.

Why this matters

Recommended schema properties unlock richer SERP layouts — without them you get the basic rich result instead of the enhanced one.

Learn more ▾

Recommended properties expand what Google can render. E.g., adding aggregateRating to Product unlocks star ratings; adding image to Article unlocks the image-card variant. Each recommended property is a direct SERP-real-estate gain.

URL: 12 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

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.

Source: Open Graph Protocol

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.
