About the Meta Tag Analyzer
The Meta Tag Analyzer fetches any URL and audits everything search engines and social networks read first: title, meta description, canonical, robots directives, Open Graph, Twitter Cards, H1 structure, language declaration and JSON-LD structured data — rendered as a pass/check list with a pixel-true Google SERP preview.
After fixing tags, re-run the analyzer to confirm, then use the Redirect Checker to verify the canonical URL is reachable in a single hop and the Server Response Time Test to keep TTFB in the green.
Google truncates titles at roughly 580 pixels (about 50–60 characters) and descriptions at around 920 pixels (about 150–160 characters). This analyzer counts characters and flags anything likely to be cut off in the search results.
No. Google has ignored the meta keywords tag since 2009. Title, meta description, canonical, robots directives and structured data are the tags that actually influence how your page appears and ranks.
Open Graph (og:) tags control how your page looks when shared on Facebook, LinkedIn or WhatsApp — title, description and preview image. Twitter Cards do the same for X/Twitter. Missing tags mean shares render as bare links with no image.
The canonical tag tells search engines which URL is the primary version of a page, consolidating duplicate variants (with/without www, tracking parameters, http/https). A missing or wrong canonical is one of the most common causes of duplicate-content issues.
