Meta Tag Analyzer

At minimum, every page needs a unique title tag, a meta description, and a canonical URL so search engines know which version of the page to index. For social sharing you also want Open Graph tags (og:title, og:description, og:image) and a Twitter Card tag so links render with a proper preview. This Meta Tag Analyzer checks all of those plus robots and viewport tags for any URL and flags the important ones that are missing.

The meta description is the snippet text search engines may show under your page in results, while Open Graph (og:) tags control how your link looks when shared on social platforms like Facebook and LinkedIn. They serve different audiences, so you generally want both, and the og:title and og:description don't have to match your SEO title and description word for word. The analyzer reports each set separately so you can confirm both are present and reading sensibly.

If a shared link shows no preview thumbnail, the page is usually missing an og:image tag, or the image URL isn't an absolute, publicly reachable URL. Social platforms read og:image (and twitter:image as a fallback) at share time, so the tag has to be in the raw HTML the crawler sees. Run the URL through this analyzer to confirm whether og:image and twitter:image are actually set, since a missing one is the most common cause of a blank preview.

A canonical tag tells search engines which URL is the master version of a page, which prevents duplicate-content issues when the same content is reachable via multiple URLs (trailing slashes, tracking parameters, http vs https). A missing or wrong canonical can split ranking signals or cause the wrong URL to be indexed. The analyzer marks the canonical as an important tag and shows you the exact value it found, so you can verify it points where you intend.

You can check a single page's current title, description, canonical, and social tags any time by running its URL through this analyzer. To catch changes you'd otherwise miss, SiteGauge can re-check a page on a schedule and alert you the moment a title, meta description, canonical, or OG image is edited, which are the on-page SEO signals that often move rankings. That turns a one-off snapshot into ongoing monitoring of your own pages or a competitor's.
