Frequently asked questions
Is the SEO Analyzer really free?
Yes. You can analyze any website and view the full report for free — no signup, no credit card and no usage limits for normal use.
What does the SEO audit check?
It runs a comprehensive audit covering on-page SEO (titles, meta, headings, images), technical SEO (HTTPS, mobile, robots.txt, sitemap, indexability, broken links), content quality (word count, readability, keywords), structured data (JSON-LD schema) and real performance metrics including Core Web Vitals via Google PageSpeed Insights.
How accurate are the performance scores?
Performance, accessibility, best-practices and Core Web Vitals come directly from Google PageSpeed Insights (Lighthouse), the same engine Google uses, so they reflect real, industry-standard measurements.
Can I share my SEO report?
Every report gets a unique, permanent public URL. You can copy the link, share it natively or post it on social media, and anyone with the link can view the full report.
How long does an analysis take?
Most audits complete in 20–40 seconds. We fetch your page, run technical and content checks, validate schema and measure page speed before generating your recommendations.
Do you store my report?
Yes — reports are stored so you (and anyone you share the link with) can revisit them later and track improvements over time with historical comparisons.
