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

Action

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

REVIEW

Brand Presence

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

59/100

Site name appears as

Page title	読売新聞オンライン : きょうの最新ニュース・速報：発行部数No.1
og:site_name	読売新聞オンライン
twitter:site	@Yomiuri_Online
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

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.

PASS

og:image is not reachable

The og:image URL could not be fetched. Social platforms won't be able to display it.

Got: https://www.yomiuri.co.jp/ogp.jpg?type=ogp

URL: https://www.yomiuri.co.jp/ogp.jpg?type=ogp

The og:image URL could not be fetched. Social platforms won't be able to display it.

Why this matters

An unreachable og:image URL (404, DNS fail, slow timeout) means social platforms cache the failure and serve no image for hours.

Learn more ▾

Social platforms (Facebook, Twitter) cache OG metadata aggressively — including failed image fetches. A momentarily-broken og:image can leave your shares imageless for hours. Test og:image URLs in Facebook's Sharing Debugger to force re-cache after fixing.
