No structured data (JSON-LD) found

Adding structured data helps search engines understand your content and can enable rich results.

Why this matters

Without schema.org markup, your pages can't appear as rich results (stars, FAQs, recipes) in search.

Learn more ▾

Structured data is what unlocks rich snippets — review stars, FAQ accordions, recipe cards, breadcrumbs, etc. — that take up more SERP space and dramatically improve click-through. The schema.org vocabulary is well-documented and JSON-LD is the easiest format.

No structured data found

Structured data (JSON-LD) helps search engines understand your content better. Adding it can improve your search result appearance.

Common types include:

WebSite — your site identity and search box
Organization — your company information
Article — blog posts and news articles
Product — e-commerce product pages
BreadcrumbList — navigation paths

Brand Presence

Site-name consistency, favicon, social image, meta tags, schema, and contact signals

REVIEW

Brand Presence

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

70/100

Site name appears as

Page title	Flightradar24
og:site_name	Flightradar24
twitter:site	@flightradar24
Organization.name	—

Consistent

Brand assets

Favicon

15/15

covers multiple sizes, apple-touch-icon + SVG

Social share image

20/20

og:image + twitter:image set

Meta completeness

20/20

Organization schema

0/15

Contact info discoverable

0/10

no contact info discoverable

Findings

Missing brand name in: Organization.name
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.

Open Graph

Open Graph tags are well configured for social sharing.

PASS

Open Graph tags are well configured for social sharing.

Invalid twitter:card value: "Application"

Valid values are: summary, summary_large_image, app, player.

Got: Application

og:title is long (66 characters)

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

Got: 66 chars Expected: 25–60 chars

Missing og:url

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

URL: Application

Valid values are: summary, summary_large_image, app, player.

Why this matters

Invalid twitter:card value means Twitter renders no card at all — your shares appear as plain-text URLs.

Learn more ▾

twitter:card accepts only 'summary', 'summary_large_image', 'app', or 'player'. Anything else (typos, made-up values) means Twitter falls back to no-card rendering. Use 'summary_large_image' for most blog/article content; 'summary' for compact previews.

Source: Twitter Developer Platform

URL: 66 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

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.
