Check SEO meta tags from the live page source
Toolmera extracts the title tag, meta description, canonical URL, meta robots directive, viewport, document language and charset. The values shown come from the fetched response, which is useful when a CMS preview says one thing but the production page source sends something different.
Title and description character counts are shown as diagnostics rather than rigid pass-or-fail ranking rules. Search engines can rewrite snippets, and the best metadata is primarily descriptive, relevant and distinct for the page.
Open Graph and Twitter Card metadata
Social platforms often use Open Graph or Twitter Card tags to build link previews. The checker surfaces og:title, og:description, og:image, og:url, og:type, twitter:card, twitter:title, twitter:description and twitter:image when present.
This makes the tool useful for long-tail tasks such as checking why a shared page has the wrong image, whether a social title differs from the SEO title or whether a migrated domain still declares an old og:url.
Canonical and robots metadata deserve special attention
A canonical URL can point search engines toward a preferred version of similar content, while a noindex robots directive asks compatible search engines not to index the page. Because both can materially affect search visibility, the checker keeps them visible alongside ordinary preview metadata.
Always review these values on the final live URL after redirects. A correctly configured CMS template can still be undermined by an edge rule, staging tag or deployment-specific response.
