Inspect title, description, Open Graph, Twitter Card, and canonical tags for any URL. See exactly how your page looks to Google and social platforms.
What it checks: title length, meta description length, Open Graph and Twitter Card tags for social previews, and canonical tag correctness — with live previews of how the page renders in Google search results and social shares.
Meta tags are HTML elements in a page's
that provide metadata about the page — title, description, keywords, and social sharing info. Search engines use the title (50–60 chars) and description (120–160 chars) to display your page in search results. Missing or poorly written meta tags directly hurt your search rankings and click-through rates.Open Graph (OG) tags control how your page appears when shared on social media platforms like Facebook, LinkedIn, and WhatsApp. Key tags include og:title, og:description, og:image (at least 1200×630px recommended), and og:url. Without them, social platforms guess what to display, often with poor results.
Twitter Card meta tags control how your links appear when shared on X/Twitter. The most important is twitter:card (use summary_large_image for a big image preview), followed by twitter:title, twitter:description, and twitter:image. They're separate from Open Graph tags, though many sites set both.
A canonical URL () tells search engines which version of a page is the "official" one when the same content is accessible via multiple URLs. For example, if your page is accessible at both http:// and https://, or with and without www, set the canonical to your preferred URL to avoid duplicate content penalties.
A meta tag checker is an online tool that fetches any URL and displays all the meta tags in its HTML head section — including title, description, Open Graph tags, Twitter Card tags, canonical URL, and robots directives. It saves you from manually viewing page source to audit SEO tags.
Enter any URL into the InfiniUm Meta Tag Checker and click Analyse. The tool fetches the page server-side and returns all meta tags with character counts and validation — no account or browser extension needed. Works for any publicly accessible URL including competitor pages.
Google typically displays 120–158 characters of meta description on desktop and around 120 characters on mobile. Descriptions longer than 160 characters are truncated with an ellipsis. Write your most important content within the first 120 characters to ensure it displays on both platforms.
