Meta tags checker — single page or whole sitemap

What the meta tags checker looks at

• Title tag — present, unique, and within the ~30–60 character range Google renders before truncating.
• Meta description — present and roughly 70–160 characters, so the snippet reads well and isn't cut off.
• Canonical — a self-referencing or intentional rel="canonical" that points where you expect.
• Language & social tags — the html lang attribute plus Open Graph / Twitter Card coverage for clean shares.

Checking a whole sitemap at once

Switch to Whole sitemap mode and enter your domain (or a sitemap URL) to bulk-check up to 200 pages in one run. The tool expands your sitemap — sitemap indexes included — then fetches each page and grades three things per URL: the title (aim for ~30–60 characters), the meta description (~70–160 characters), and the URL slug (under ~70 characters). Missing tags, over-length tags, and too-short tags are flagged in place, live summary cards keep the totals in view while the check streams in, and you can export the whole table as CSV or a readable TXT report when it finishes. Larger site? Run the check again on a child sitemap to cover the next batch of pages.

Why meta tags still matter

Your title tag and meta description are the first thing a searcher reads about your page — they shape click-through rate straight from the results page, and a title that's missing, duplicated, or truncated quietly costs you traffic you already ranked for. The canonical tag decides which URL Google credits when the same content is reachable through several addresses, and the html lang attribute and Open Graph tags decide how your page reads to translation tools and how it looks when someone shares it. None of these are visible on the page itself, so they drift out of sync after a redesign or a CMS change without anyone noticing.

Both modes check your pages live, and store nothing. To audit the meta tags across your whole site on a schedule and catch regressions after every deploy, try siteOS — or start with the in-browser meta tags previewer and the full SEO audit.
