FAQ

Is this SEO checker really free and online?

Yes. It runs in your browser and doesn’t require accounts or payments.

Does it fetch my URL and crawl my site?

No. This tool does not make network requests; you paste HTML source to analyze.

What SEO items does it check?

Core on-page signals like title, meta description, H1/headings, canonical, robots meta, links, images alt text, and optional keyword usage.

How do I get the HTML to paste?

Open the page in your browser, use “View Page Source”, then copy the full HTML (especially the <head>).

Is my content uploaded or stored?

No. The analysis happens locally in your browser; nothing is sent anywhere by this tool.

Why does the score differ from other SEO tools?

Scores depend on each tool’s weighting. Use the checklist items as guidance, not a universal ranking metric.

Can I check keyword density with multi-word phrases?

Yes. Enter the full phrase; the tool counts phrase-style matches and estimates density from page text.
