Check Essential SEO Metadata
Inspect title tags, meta descriptions, canonical URLs, robots directives, and viewport declarations.
Check your website's meta tags and identify missing, duplicate, or incomplete SEO metadata. Review title tags, meta descriptions, canonical URLs, robots directives, and social sharing tags in one place.
Meta tags provide information about a webpage to search engines, browsers, and social platforms. They help describe page content, communicate indexing instructions, and control how information may appear when a page is shared.
A well-written title tag and meta description can help users understand what a page offers before visiting it. Canonical tags help indicate the preferred URL when similar or duplicate pages exist, while robots directives communicate crawling and indexing preferences.
Although not every meta tag directly affects search rankings, reviewing them helps identify missing information and technical configuration issues. MoSanKit's free Meta Tag Checker lets you inspect metadata through a website URL or pasted HTML source.

Quick answers about checking website metadata.
A meta tag checker is an online tool that examines a webpage's HTML metadata. It helps identify title tags, meta descriptions, canonical URLs, robots directives, and social sharing tags.
Yes. You can use the MoSanKit Meta Tag Checker for free without creating an account.
You can check publicly accessible websites when their pages can be retrieved successfully. Some websites restrict automated requests. In those cases, you can paste the page's HTML source code for analysis.
There is no fixed character limit enforced by Google. Search titles are displayed according to available space and may be rewritten. Keeping titles concise and descriptive can help make them easier to understand.
Google does not enforce a fixed meta description character limit. Search snippets are generated dynamically and may be shortened or replaced depending on the search query and device.
A checker does not directly improve rankings. It helps identify metadata issues so you can make informed improvements to your website.
Search engines can generate a snippet from the page's visible content. Adding a relevant meta description can provide a useful summary, although search engines may choose different text.
Open Graph tags provide information such as a page title, description, and image to social platforms when a webpage is shared.
Yes. If a website cannot be fetched directly, you can paste its HTML source code into the checker to inspect the metadata included in that source.
No. The tool checks metadata found in the inspected HTML. It does not measure keyword rankings, indexing status, or overall search performance.
Review your page metadata, find missing tags, and identify potential issues before they affect how your pages are presented online.
