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

Rich Results Eligibility

Action

No JSON-LD found -- no rich-result eligibility

REVIEW

No JSON-LD found -- no rich-result eligibility

No JSON-LD structured data on the page

No `<script type="application/ld+json">` blocks found. Without structured data, search engines fall back to inferring page meaning from raw HTML -- which works but doesn't unlock SERP features (rich snippets, knowledge panel, FAQ accordion, breadcrumb trail). Adding even basic JSON-LD (Organization for the site identity, BreadcrumbList for navigation context) is a low-effort SEO win.

Image Optimization

Action

3 issues found across 3 images

REVIEW

3 issues found across 3 images

3 images missing explicit width/height

Images without dimensions cause layout shifts (CLS). Set explicit width and height attributes.

3 below-fold images missing loading="lazy"

Lazy loading defers below-fold images, reducing initial page weight.

2 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://lantian.pub/usr/uploads/202512/im-doing-my-part.png.thumb.png.webp, https://lantian.pub/usr/uploads/202110/nixos-social-preview.png.thumb.png.webp.

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.

59/100

Site name appears as

Page title	Lan Tian @ Blog
og:site_name	Lan Tian @ Blog
twitter:site	—
Organization.name	—

Consistent

Brand assets

Favicon

15/15

covers multiple sizes, apple-touch-icon + SVG

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
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.
