Meta Tags Analyzer checks pasted HTML for common technical SEO tags and highlights missing or weak basics. It is designed for quick audits of page source, static builds, and previews.
Technical SEO
No. Paste the page HTML or head section. This avoids server-side fetching and keeps the tool fully browser-only, so it works on staging builds not yet publicly reachable too.
No. They are practical ranges (roughly 50-60 characters for titles, 120-160 for descriptions) that help catch obvious SEO issues, not hard ranking rules enforced by search engines.
A missing canonical tag can lead to duplicate-content ambiguity when the same content is reachable at multiple URLs (with/without trailing slash, with tracking parameters, etc.), which can dilute ranking signals across near-identical pages.
Yes — paste the HTML output from your local build or a preview environment. Since the tool doesn't fetch anything externally, it works identically whether the page is live, staged, or only on your machine.
No. This checks technical tag presence and length only — it says nothing about content quality, backlinks, page speed, or search intent match, all of which matter more for actual rankings.
Open Graph tags affect how a page appears when shared on social platforms, which indirectly impacts click-through traffic even though they aren't a direct search-ranking factor — worth checking alongside core meta tags.
This tool covers the full technical SEO tag set (title, description, canonical, robots, viewport, H1, and OG basics); the Open Graph Checker focuses specifically on rendering a social preview card from OG/Twitter tags.
