REVIEW

Brand Presence

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

69/100

Site name appears as

Page title	NASA Science
og:site_name	NASA Science
twitter:site	@NASA
Organization.name	—

Inconsistent — names differ across channels

Brand assets

Favicon

15/15

covers multiple sizes + apple-touch-icon

Social share image

20/20

og:image + twitter:image set

Meta completeness

20/20

Organization schema

4/15

Organization schema present but missing all recommended fields

Contact info discoverable

5/10

contact page

Findings

Brand name differs across channels — users see inconsistent identity
Organization schema missing logo — add a logo property pointing to a square PNG
Organization schema missing url — point it at the canonical homepage
Consider adding contactPoint — helps appear in "contact us" rich results
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.

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.

PASS

2 JSON-LD block(s) found — structured data is well configured.

Missing required property "name" for Organization

The "name" property is required for the Organization schema type.

Missing recommended property "url" for Organization

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

Missing recommended property "logo" for Organization

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

Missing recommended property "sameAs" for Organization

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

2 JSON-LD blocks found

The "name" property is required for the Organization schema type.

Why this matters

Schema markup missing required properties is silently rejected by Google — your structured data appears in source but never as a rich result.

Learn more ▾

Each schema.org type has required properties (Article needs headline + author + datePublished; Product needs name + offers; etc.). Missing them means Google's rich-result eligibility check fails. The Search Console Rich Results Test surfaces specific gaps. Fix the missing property; rich results re-appear within hours.

Adding "url" 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.
