Meta Tag Checker: Scan every page.
Free meta tag checker. We scan every page in your sitemap and flag missing meta descriptions, duplicate titles, broken canonicals, and Open Graph issues - with a ranked fix list.
Why meta tags still matter (and which ones don’t)
Google has spent a decade telling people meta tags don’t matter. They mean themeta keywords tag, which they stopped using in 2009. Other meta tags still carry real weight: title drives click-through from the SERP, meta description influences click-through and is often what Google shows below the title, canonical determines which URL gets indexed, robots controls whether the page is indexable at all, and Open Graph + Twitter Cards control how the page renders when shared on social.
What we check, page by page
- Title tag — present, unique, within character bounds (~60 chars before SERP truncation), keyword-front-loaded.
- Meta description — present, unique, within bounds (~155 chars), naturally written.
- Canonical — present, absolute URL, self-referential or correctly pointed.
- Robots — checks for accidental noindex on pages that should be indexed (the most expensive single mistake in SEO).
- OpenGraph — og:title, og:description, og:image, og:url all populated.
- Twitter Card — at minimum twitter:card type set correctly (summary or summary_large_image).
- Hreflang — for international sites, validates language/region codes and self-references.
Pattern detection across the whole site
The free tier covers up to 500 pages, but the real value is in pattern analysis. Most meta-tag bugs are template-level — a single CMS template generates the same broken tag on thousands of pages. We aggregate findings to surface the templates rather than the individual pages, so the fix list is short and actionable rather than overwhelming.
We also flag duplicate titles and duplicate meta descriptions across the site, since either is a flag for Google to deprioritise both pages. The deduplication rules are exactly Google’s — exact match plus close paraphrase.
