FIX

Brand Presence

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

53/100

Site name appears as

Page title	Prometheus - Monitoring system & time series database
og:site_name	—
twitter:site	—
Organization.name	—

Consistent

Brand assets

Favicon

8/15

covers 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: og:site_name, twitter:site, Organization.name
Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
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.

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

Missing og:type

The og:type tag helps social platforms categorize the content.

Missing og:site_name

The og:site_name tag displays the website name in social previews.

The og:type tag helps social platforms categorize the content.

Why this matters

Default og:type is 'website' but the right value (article, product, profile) unlocks richer metadata fields and higher engagement.

Learn more ▾

og:type controls which other og: fields a platform respects. og:type=article enables og:article:published_time, author, and section — surfaced in news cards. og:type=product enables price/availability fields surfaced by Pinterest and shopping integrations. Default 'website' silently disables those.

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.
