3 issues found across 7 images
Warning::
7 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
7 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Warning::
All 7 images use legacy formats (JPEG/PNG/GIF)
WebP offers 25-35% smaller files than JPEG. Use <picture> with <source type="image/webp"> for modern format support.

REVIEW

Brand Presence

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

Findings

  • Missing brand name in: og:site_name, twitter:site, Organization.name
  • 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.

Ideal length is 25–60 characters for social sharing previews.

Expected: 25–60 chars
Why this matters

og:title very short — may render with awkward whitespace in social cards.

URL: 4 chars

Ideal length is 55–200 characters for social sharing previews.

Expected: 55–200 chars
Why this matters

og:description very short — provides little context in social cards.

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.

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.

The "name" property is required for the WebSite 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 "description" 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.

PASS
2 JSON-LD block(s) declaring 1 schema type(s)
Info::
SiteLinks Search Box markup detected
The page declares a `WebSite` schema with a `potentialAction` of `SearchAction`. This makes the homepage eligible for Google's in-SERP search box -- a high-visibility SERP feature for branded queries.
Info::
1 rich-result schema type(s) declared
Inventory of structured-data types on the page (each may unlock a different SERP feature): WebSite (×2) Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.
