Meta tags checker

What meta tags are

Meta tags are snippets of HTML in the head of a page that describe its content to browsers and search engines. The most influential for SEO are the title tag, the meta description, and robots directives. Other tags control social sharing, character encoding, viewport behavior, and canonical URLs.

Which tags this tool reveals

The checker extracts the meta tags present in the page source and displays them in an organized view. This typically includes the page title, meta description, meta keywords if present, robots directives, Open Graph tags, Twitter card tags, canonical link, and viewport settings. Seeing the actual values helps you verify that they are present, unique, and correctly formatted.

Why meta tags need checking

• Search appearance. The title and description shape how a page is presented in search results and influence click-through rates.
• Indexing control. Robots meta tags and canonical links tell search engines whether and how to index a page.
• Social sharing. Open Graph and Twitter tags determine how links look when shared on social platforms.
• Duplicate content. Missing or incorrect canonical tags can cause indexing problems.

Limitations

This tool reads the HTML that is served for a single URL. It does not evaluate whether the tags are optimal for ranking, render the page, or check how search engines actually interpret the tags. Dynamically injected tags may not appear if they are added by JavaScript after the initial response. Use the extracted values to confirm what is present and compare them against SEO best practices.
