Adding structured data helps search engines understand your content and can enable rich results.

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.

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
Info::
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.

Open Graph / Twitter Card Depth
1 OG/Twitter depth issue(s) detected
PASS
1 OG/Twitter depth issue(s) detected
Info::
1 Twitter Card field(s) differ from Open Graph counterparts
Twitter Cards inherit values from Open Graph tags when the Twitter-specific tag is absent (`twitter:title` falls back to `og:title`, etc.). Explicitly-set Twitter values that DIFFER from OG are usually stale -- the marketing team updates `og:title` for FB/LinkedIn previews and forgets to update `twitter:title` separately, leaving Twitter showing the old text. Mismatches: - title: twitter="costdown.org | Đề án Costdown", og="Costdown.org | Giảm Chi Phí Sản Xuất & K..." Fix: either remove the redundant Twitter-specific tags (rely on inheritance) or sync them when updating OG.
Got: 1 field(s) differ
