What this checker looks at

Meta tags are the small bits of HTML in the <head> that tell Google and social platforms how to present your page in search results and link previews. Get them wrong on one or two pages and you might miss out on clicks — get them wrong across an entire site and you lose a lot of traffic.

This scanner pulls every URL from your sitemap and reads each page's <title>, meta description, canonical link, robots directive, Open Graph tags and Twitter Card tags. The results show up in a sortable, filterable table so you can spot patterns across the whole site, not just one page at a time.

Common issues this checker finds

  • Missing title or meta description. Without these, Google has to guess what to put in the search snippet — usually badly. Empty descriptions are flagged as critical so you can prioritise them.
  • Over-long titles (> 60 chars) and descriptions (> 160 chars). Anything longer gets truncated with an ellipsis in search results, often cutting off the most important words. We surface the exact length so you can edit precisely.
  • Accidental noindex or nofollow. A stray robots directive can quietly de-index a page that should rank. The scanner reads the full robots value on every page so you can catch these immediately.
  • Missing canonical tag. Pages without a canonical can cause duplicate-content confusion, especially when query parameters or trailing slashes create multiple URLs for the same content.
  • No Open Graph or Twitter Card tags. When someone shares your link on LinkedIn, X or Slack, OG tags decide whether you get a rich preview with an image or a sad bare URL. Both presence flags are reported.

Best-practice cheat sheet

  • Title: 50–60 characters, unique per page, the most important keyword near the start.
  • Description: 120–160 characters, written for humans (not keyword stuffing).
  • Canonical: point at the absolute, https, lowercased version of the URL.
  • Open Graph: at minimum og:title, og:description, og:image, og:url.
