How the GEO optimizer works
This tool runs entirely in your browser and never sends your text anywhere. It looks at the same signals that AI answer engines use when deciding what to cite, then turns them into a single, readable score.
- Paste. Drop in an article, a blog post or a page's copy. If you paste raw HTML, the tags are stripped first.
- Score. The analyzer checks eight dimensions — depth, structure, data, citations, FAQ format, definitions, examples and freshness — and weights them into a 0–100 GEO score.
- Fix. Every dimension that is weak shows a plain-English tip, and the “Priority fixes” list ranks what will move the needle most.
- Repeat. Edit your draft and run it again — the score updates instantly, so you can see improvements before publishing.

When should you run a GEO check?
GEO (Generative Engine Optimization) is the practice of making content easy for AI search engines to find and quote. Run this tool when:
- Writing a blog post or guide? Check it before publishing so AI answers link back to you instead of a competitor.
- Low AI traffic? A weak GEO score often explains why ChatGPT or Perplexity rarely cite a page that ranks fine in classic search.
- Refreshing old content? Re-run after edits to confirm the freshness and data signals improved.
- Building a content playbook? Use the per-dimension tips as a repeatable checklist for your writers.
- Pitching as a source? Strong structure, stats and citations are exactly what AI answer engines prefer to quote.
Frequently asked questions
What is GEO (Generative Engine Optimization)?
GEO is the practice of optimizing content so that AI-powered search and answer engines — like ChatGPT, Perplexity, Claude and Google's AI Overviews — choose to cite and quote it. It builds on classic SEO but emphasizes depth, statistics, clear structure and authoritative citations rather than just keywords and backlinks.
Is my content uploaded or stored?
No. All analysis happens in your browser with JavaScript. Your text is never sent to a server, logged, or saved. Close the tab and it is gone.
Is the score a guarantee that AI will cite me?
No tool can guarantee citation — AI engines consider many factors, including their own training data and the query. The GEO score measures how well your content matches the signals those engines are known to favor, which strongly improves your odds.
What does a good GEO score look like?
75–100 means your content is well structured for AI citation; 50–74 is workable but improvable; below 50 is likely to be overlooked. The “Priority fixes” list tells you exactly where to start.
Do I need to paste clean text, or can I use a URL?
This tool analyzes pasted text. Copy the article body from the page (or paste the page's HTML — tags are stripped automatically). Paste only the content you want scored, not an entire site.
