Structured Data

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.

Source: Google Search Central / schema.org

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

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

56/100

Site name appears as

Page title	Seesaaブログ（シーサー）：無料でアフィリエイトからまとめブログまで
og:site_name	Seesaaブログ（シーサー）：無料でアフィリエイトからまとめブログまで
twitter:site	—
Organization.name	—

Consistent

Brand assets

Favicon

12/15

covers 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

0/10

no contact info discoverable

Findings

Missing brand name in: twitter:site, Organization.name
Add twitter:image — Twitter falls back to og:image only when it's larger than 300×157
Add an apple-touch-icon and at least two PNG sizes (32x32 + 192x192)
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.
