FIX
7 issues found across 24 images
Warning::
1 images significantly larger than display size
Resizing to display dimensions could save approximately 460 KB.
Got: ~460 KB wasted
Warning::
23 images missing explicit width/height
Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.
Info::
6 below-fold images missing loading="lazy"
Lazy loading defers below-fold images, reducing initial page weight.
Warning::
All 17 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.
Warning::
Total image weight: 1187 KB (1.2 MB)
Consider compressing images, using modern formats, and serving appropriately sized images.
Info::
2 image(s) wider than 400px without srcset (no responsive serving)
These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://tdsolarenergy.com/assets/img/pv-06.jpeg, https://tdsolarenergy.com/assets/img/pv-05.jpeg.
Info::
1 image(s) rendered at a different aspect ratio than the source
The displayed dimensions distort the source -- CSS is forcing the image into a container at the wrong ratio, producing visible stretching or squashing. Either crop the source to match or use object-fit: cover (and accept the crop). Sample: https://tdsolarenergy.com/assets/img/pv-06.jpeg.

REVIEW
1 autoplay media element(s) -- all muted
Info::
1 autoplay media element(s) on page (muted)
Autoplay video transfers bytes whether the user engages or not -- a sustainability concern even when muted. Consider replacing with a static poster image and a click-to-play overlay; the user opts in to the bandwidth cost.

Brand Presence

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

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
  • Single favicon only — add apple-touch-icon for iOS home-screen and high-DPI support
  • Organization schema missing logo — add a logo property pointing to a square PNG
  • 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.

Titles over 60 characters may be truncated in social sharing previews.

Expected: 25–60 chars
Why this matters

og:title borderline-too-long — Facebook/LinkedIn may truncate. Aim for ~60-70 characters max.

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.

Warning::
Missing required property "address" for LocalBusiness
The "address" property is required for the LocalBusiness schema type.
Info::
Missing recommended property "openingHours" for LocalBusiness
Adding "openingHours" can improve how search engines display your content.

The "address" property is required for the LocalBusiness 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 "openingHours" 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.

Info::
1 rich-result schema type(s) declared
Inventory of structured-data types on the page (each may unlock a different SERP feature): LocalBusiness Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.
All checks on this page are automated. Results are estimates - run targeted manual reviews when the score affects a release decision.
