Free SEO checker FAQs
What does this free SEO checker analyze?
It runs an on-page SEO audit of the initial HTML response: meta title and meta description, H1–H6 headings, canonical and robots directives, Open Graph and Twitter tags, structured data, favicon, robots.txt, sitemap, custom 404, HTTPS/HSTS, mixed content, compression, HTML size, and content length signals.
Is this website SEO audit tool free to use?
Yes. DebuggedSoftware’s free SEO checker lets each visitor run three website SEO checks per day. When you need a full technical SEO engagement, we can fix on-page issues, performance, and the code behind the site.
How is an on-page SEO analysis different from Google PageSpeed?
This free SEO checker focuses on crawlable on-page SEO factors (titles, meta tags, headings, indexing signals, and security headers). It does not replace a lab Core Web Vitals run in a headless browser. Use both for a complete website SEO audit.
Will JavaScript-rendered pages score correctly?
The tool fetches the first HTML response without executing JavaScript. SPAs and client-rendered apps may look thin or missing headings here even if Google renders them later. For accurate audits of JS-heavy sites, critical SEO content should be in the initial HTML or we can review the rendered page for you.
Can DebuggedSoftware fix the SEO issues this checker finds?
Yes. We provide SEO services and custom software work (Django, Laravel, WordPress, and more) to fix titles, technical SEO, structured data, performance, and conversion UX for teams in the USA, Canada, and Europe.
