Paste a URL or your content and get an instant on-page SEO audit. The On-Page SEO Analyzer checks your title, meta description, headings, links, images and schema, then scores your page for optimization, naturalness (AI-writing tells) and readability. It also runs AI research for query fan-out, Google’s Web Guide clusters, and concrete fixes you can apply. It’s free, runs entirely in your browser, and nothing you paste is stored.
How to use it
- Enter your page URL (or, if your site blocks fetching, paste the page content instead).
- Add your target keyword so the tool can score keyword intent, not just exact match.
- Read the scores and the checklist — every check is pass, warn or fail with a specific fix.
- Use the AI tabs for query fan-out, Web Guide clusters and rewrites. Add your own OpenAI, Anthropic or Gemini key, or open the prompt free in ChatGPT, Claude or Gemini.
- Export the report or grab the embed code to add the tool to your own site.
What it checks
- Title tag and meta description (length + keyword intent)
- Heading structure (one H1, clean H2s, no skipped levels)
- Internal and external links, and anchor-text quality
- Images and alt text
- Schema / structured data, mobile viewport, canonical, indexability
- Content depth, readability (Flesch) and naturalness (the AI-writing tells to remove)
- AEO research: query fan-out, Web Guide clusters and competitive gaps
Frequently asked questions
Is it really free? Yes. The audit and scores are completely free with no signup. The AI research features are optional and run on your own AI key, or you can open the prompt free in ChatGPT, Claude or Gemini.
Do I need an API key? No for the audit. A key is only needed if you want the AI analysis to run inside the tool. Without one, every AI feature gives you a “copy prompt” and “open in ChatGPT / Claude / Gemini” option.
Is my content stored anywhere? No. Everything runs in your browser. Nothing you paste is sent to or saved on this site.
Can I put this tool on my own site? Yes. There’s an “embed on your site” option that gives you a snippet to paste, free.
