EFSI SEO AEO GEO Checker

SEO, AEO and GEO analysis for the current page. Deterministic checks run locally; AI features are opt-in.

EFSI scores the page you are on for search engines (SEO), answer engines (AEO) and generative engines (GEO), then shows exactly what to fix. Open any page, click the EFSI icon and press Analyze Page. In seconds you get three scores, a prioritised list of fixes and a full dashboard in Chrome's side panel. WHAT YOU GET - Three scores: SEO, AEO and GEO. Every factor, its weight and the checks behind it are shown, so nothing is a black box. - Prioritised issues: each one has a severity, why it matters, the fix and the effort. - Technical SEO checks: titles, meta descriptions, headings, canonical tags, structured data, link and image basics. - AEO checks: direct answers, question coverage, structure, clarity and evidence. - GEO checks: entity clarity, topical coverage, information gain, evidence and citation readiness. - Competitor comparison: compare up to 5 pages you choose and see content and entity gaps. - Optional SERP overlay: pick competitors straight from Google, Bing and DuckDuckGo results. - AI visibility log: track whether your brand shows up in AI answers. - Report export: share the analysis with your team or client. WHO IT IS FOR SEO specialists, content writers, marketers, developers and agencies who want a fast, honest read on how ready a page is for both classic search and AI answers. PRIVATE BY DEFAULT - All scoring runs in your browser. EFSI has no servers, no analytics and no tracking. - A page is read only when you click Analyze. - AI features are optional and off until you turn them on and add your own API key (Anthropic, OpenAI or an OpenAI-compatible endpoint). - With AI on, only a trimmed excerpt (first 1,500 words), the headings and an issue summary are sent to the provider you chose. Never raw HTML, links or images. - Exclude any domain, keep or turn off history, and delete all data in one click. HONEST LIMITS Scores are heuristic checks of observable page characteristics. They do not predict or guarantee rankings, or citations by any search engine or AI system. Analysis is English-first. Entity and E-E-A-T checks flag signals and do not verify truth or credentials. Link checks flag placeholder links and do not find real 404 errors. AI features use your own API key and may incur charges from your AI provider. HOW TO START 1. Open any website. 2. Click the EFSI icon. 3. Press Analyze Page, or open the full dashboard in the side panel. Built by Faircode Infotech.
