Why Meta Tag Analyzer on Pixlane
Meta tags control how your page appears in search results and social shares. A missing canonical causes duplicate content; wrong OG tags ruin link previews; a too-long title gets truncated in SERPs. Pixlane parses your HTML client-side and checks every meta concern in one pass: title/description length, OG/Twitter completeness, hreflang consistency, robots directives, viewport, theme-color, and more.
Complete SEO Pass — Title (50-60 char target), meta description (150-160), canonical, meta robots, hreflang, Open Graph (12+ properties), Twitter Card (5 variants), viewport, theme-color, favicon — all in one view.
Social Share Preview — Live preview of how your page appears on Facebook, Twitter/X, LinkedIn, Discord, Slack, WhatsApp. Catches missing or broken og:image URLs before sharing.
Hreflang Audit — Validates hreflang alternates: correct codes (ISO 639-1 + ISO 3166-1), bi-directional references, x-default presence, self-reference.
Conflict Detection — Flags conflicts like `meta robots=noindex` alongside `meta googlebot=index`, or mismatched canonical vs og:url — quiet bugs that confuse search engines.
Frequently Asked Questions
What's the ideal title length?
50-60 characters is Google's rough display limit before truncation. Under 30 is too short (suggests unspecific content); over 70 is often cut. Mobile truncates earlier (~55). The tool flags both extremes.
Why does Open Graph matter?
OG tags (og:title, og:description, og:image) control how your URL appears when shared on Facebook, LinkedIn, Slack, Discord, and most modern apps. Without OG, social platforms guess or show nothing.
Is this tool private?
Yes. All analysis runs in your browser. URL fetching uses CORS where allowed; otherwise paste the HTML directly. Nothing is uploaded or logged.
Is this tool free?
Yes. Meta Tag Analyzer on Pixlane is completely free with no signup required.
