Free Meta Checker
Check the metadata your page gives crawlers.
Free, no-signup check for missing meta tags, social preview tags, structured data, and a few AI-search readiness signals in one small report.
Core tags
Title, description, canonical, robots, and H1.
Preview tags
Open Graph and Twitter/X card coverage.
AI signals
Structured data and llms.txt discovery.
What this tool checks
Eight categories of metadata, each mapped to a specific crawler or distribution channel.
<title>
Page Title
Shown in SERP, browser tab, and social card headline. Google may rewrite it if missing or over 60 characters.
<meta name="description">
Meta Description
Controls the SERP snippet text. Not a ranking factor, but a well-written description directly lifts click-through rate.
<link rel="canonical">
Canonical URL
Tells Google the authoritative version when near-duplicate URLs exist — e.g. with and without trailing slash.
<meta name="robots">
Robots Directives
Per-page crawl and index control. Missing is fine; a stray noindex silently removes the page from all search engines.
og:title / og:image
Open Graph Tags
Required for rich link previews on LinkedIn, Facebook, Slack, and Discord. A missing og:image usually renders as no image.
twitter:card
Twitter / X Card
Enables large-card previews on Twitter and X. Falls back to Open Graph if absent, but explicit tags are more reliable.
JSON-LD / schema
Structured Data
Powers rich results: FAQ dropdowns, article bylines, breadcrumbs, review stars. Required for most SERP features.
llms.txt / ai-meta
AI Discovery
llms.txt presence, meta ai-instructions, and robots.txt AI agent rules — newer signals for ChatGPT, Perplexity, and Claude.

Common metadata mistakes
The six issues that show up most often in audits — and that are cheap to fix once you know they exist.
Missing og:image
The most common gap. Every page meant to be shared needs an og:image at least 1200×630 px. Without it, social shares show a blank card.
Duplicate title tags
The same title on multiple pages prevents Google from distinguishing them and dilutes ranking signals across all copies.
Canonical pointing to a different URL
A misconfigured canonical silently tells Google to prefer a different page, de-prioritising the one you actually want ranked.
Meta description over 160 characters
Google truncates long descriptions, often cutting off the key message. Keep descriptions between 120 and 155 characters.
No structured data on content pages
Blog posts, product pages, and FAQ pages without JSON-LD are ineligible for rich results — FAQ accordions, article images, review stars.
No llms.txt anywhere on the domain
AI search engines use llms.txt to understand your product. Without it, AI citations rely entirely on whatever the model can infer from raw HTML.
Frequently asked questions
What is a meta checker?
A meta checker fetches a live URL and reads its HTML to report on the metadata tags that control how search engines, social networks, and AI crawlers display and index the page.
Does meta description affect Google rankings?
No. Google has confirmed that meta description is not a ranking signal. It does affect click-through rate because Google often uses it as the visible SERP snippet.
What does a canonical tag do?
A canonical (<link rel="canonical">) tells Google which URL is the official version when near-duplicate pages exist — for example, content accessible at both http and https, or with and without a trailing slash.
Why does og:image matter?
When a link is shared on LinkedIn, Facebook, Slack, or iMessage, the platform fetches og:image to build the preview card. A missing og:image produces a card with no image, which typically receives far fewer clicks.
What is llms.txt?
llms.txt is a plain-text file at the root of a domain (e.g. acme.co/llms.txt) that describes the site to large language models. AI search engines like ChatGPT and Perplexity can read it to cite your product more accurately.
