Meta Tag Checker

Audit titles, descriptions, canonicals, lang attributes, and viewport tags before you publish another landing page.

Run your first audit to visualize meta titles, descriptions, canonical tags, and responsive settings here.

What is a meta tag checker?

Meta tags control how your page appears in search results and how search engines interpret each locale. This checker fetches your live title, meta description, canonical URL, lang attribute, viewport tag, and favicon so you can fix mistakes without manually viewing source code.

Why audit titles and descriptions?

Search engines truncate titles above ~60 characters and rewrite weak descriptions. By auditing lengths, you can tighten messaging, keep canonical signals clean, and ensure every landing page aligns with current campaigns.

SERP essentials

  • <title> — 30–65 characters, keyword-rich headline.
  • Meta description — 120–165 characters that summarize the offer and CTA.
  • Canonical URL — Primary URL reference that prevents duplicate content.

Technical hygiene

  • <html lang> — Language code for each locale template.
  • Viewport meta — width=device-width, initial-scale=1 for responsive layouts.
  • Favicon — Brand icon shown in SERPs and browser tabs.

Everything you need tooptimize SEO tags

Get answers to the most common questions about meta titles, descriptions, canonicals, and responsive markup.

Enter your URL and we’ll fetch the live title and meta description, count characters, and flag whether they fall inside the recommended 30–65 and 120–165 character ranges.
Canonicals consolidate duplicate URLs (UTM parameters, filtered pages, localized variants) so link equity and structured data roll up to one primary page.
The report surfaces the exact lang value from your <html> tag so you can confirm each locale (en, de, fr) is configured correctly for multilingual SEO.
No. Each audit is generated on demand, shown in your browser, and discarded. Nothing is saved or shared.
Yes—many “duplicate without user-selected canonical” or “missing description” issues can be solved by tightening the tags this tool highlights.
As long as the URL is publicly accessible (or temporarily allowlisted), you can audit metadata before merging to production.
Absolutely. Use unique titles and descriptions per language or region to avoid duplicate snippets. The lang attribute makes sure Google serves the right variant.
Yes. If the responsive viewport tag is missing or incomplete, you’ll see a warning so you can patch it before mobile users land on the page.
Audit whenever you launch new campaigns, clone templates, or notice CTR drops. Quarterly reviews keep content fresh and SERP-safe.
Pair strong metadata with structured data, clean headings, and fast load times to maximize click-through rates and rankings.
