SEO Analyzer: common questions.

Is SEO Analyser free to use?

Yes — completely free, no signup and no credit card. Enter a URL and you get the full report in seconds.

What exactly does it check?

On-page SEO (titles, meta, headings, images), technical health (HTTPS, robots.txt, sitemap, indexability), Core Web Vitals via Google Lighthouse, structured-data validation, and content quality — plus an AI summary with prioritised fixes.

Can I share the report?

Every report gets a permanent public URL you can share with your team or clients, and revisit later to track progress.

How is it different from running Lighthouse myself?

It combines Lighthouse performance data with a full SEO crawl and an AI recommendation engine that ranks fixes by impact — one report instead of four separate tools.
