SEO metadata checker
Paste a URL. We extract the title, meta description, canonical, Open Graph, Twitter card, and JSON-LD blocks, then grade what is missing or off.
Metadata is the only SEO surface that earns clicks without anyone visiting your site.
A better title moves CTR. A better meta description moves CTR. A better Open Graph image moves social referral. All without one extra visitor needed.
Title tag length
50–60 characters fit Google's display width. Past 65 you risk truncation; below 25 you sound generic.
Meta description
140–160 characters. Treat it as an ad: specific benefit, then proof, then action. Generic descriptions kill CTR.
Canonical link
Every indexable page should declare its canonical URL — otherwise duplicates eat your ranking.
One H1 per page
Multiple H1s confuse the topical signal. One H1 that names the page's primary topic is the cleanest signal.
Open Graph
og:title + og:description + og:image render the social preview. Missing og:image makes shares look bare.
JSON-LD
Structured data turns prose into facts. Organization, WebSite, Article, FAQPage, Product — each enables a specific rich result.
Frequently asked questions
- What does this tool actually check?
- Title length, meta description length, canonical link tag, H1 count, Open Graph tags, Twitter card tags, and JSON-LD structured data blocks. Each gets a green/yellow/red verdict with a one-line reason.
- Why is this a separate tool from the full audit?
- Metadata is the highest-leverage and lowest-effort layer of SEO. We split it out so you can fix titles and descriptions in an afternoon without running the full eight-lens audit. The full audit on the home page covers everything else.
- Will you fix the metadata for me?
- No — this is a diagnostic. The output tells you what is missing or off, and each row links to the guide explaining how to fix it. The full paid report includes per-issue fix recommendations.
- Does this work on pages that need JavaScript to render?
- We fetch the raw HTML. Tags injected after JavaScript executes will not be visible to this tool (or to most AI crawlers either). If your metadata is JS-rendered, fix that first — server-render metadata so crawlers see it.
Metadata is one lens. Run all eight.
The full audit covers crawlability, technical SEO, content clarity, AI readability, entities, schema, and internal linking too.
