AI Visibility Checker Methodology: GEOCARA Scoring
GEOCARA's free AI Visibility Checker measures whether a public website gives search and answer engines the structure, evidence, identity, and crawl access needed to retrieve and cite its content. It analyzes up to five representative pages, calculates eight 0-100 readiness sub-scores, averages them into a GEO Authority Score, and returns prioritized, page-specific improvements.
What the free checker measures
The checker is a technical and content readiness audit. It answers a practical question: if an AI-assisted search system retrieves these pages, are they structured and supported well enough to be understood, trusted, and quoted?
It does not claim that every AI platform has queried the website during the scan. A live mention tracker answers a different question by repeatedly submitting prompts to ChatGPT, Perplexity, Gemini, Claude, Copilot, or other engines and recording whether a brand appears. Readiness and observed visibility are complementary measurements, not interchangeable labels. See the complete comparison in AI visibility readiness vs AI mention tracking.
You can run the free AI visibility checker without creating an account. The public result keeps the overall score and selected priority categories visible.
How GEOCARA selects and crawls pages
The free scan starts from the submitted public domain and analyzes up to five HTML pages. The crawler favors representative, indexable pages such as the homepage, product or service pages, about pages, and substantive editorial content. It removes URL fragments and tracking parameters during deduplication and avoids non-HTML assets such as images, archives, fonts, and media files.
The crawler first attempts a normal HTTP retrieval. When a page looks like an empty application shell or requires client-side rendering, the audit can fall back to a browser-rendered capture. A page must still be publicly reachable: authenticated dashboards, CAPTCHA-protected routes, firewall challenges, and unavailable servers cannot be scored as ordinary public content.
The five-page limit makes the result a useful baseline, not a complete inventory of a large website. A deeper audit can analyze more pages and reveal template-level differences that a small sample may miss.
The eight GEO readiness sub-scores
Each analyzed page contributes to eight sub-scores. Most site-level sub-scores are the arithmetic mean of the page-level results. FAQ presence is calculated from the share of analyzed pages that contain a detectable FAQ, while E-E-A-T also includes domain-level signals.
| Sub-score | What GEOCARA inspects | What a stronger implementation looks like |
|---|---|---|
| Informational density | Specific facts, entities, examples, useful detail, and the ratio of substantive information to vague copy | Concrete claims and examples that can stand alone when extracted |
| Answer First | The first relevant paragraph and whether it provides a concise direct answer | A useful 40-60 word opening for English and French, with a partial score for a 60-80 word answer |
| HTML structure | H1 count and the presence of a meaningful H2 hierarchy | One H1 and at least two descriptive H2 sections |
| Schema quality | Valid JSON-LD signals, @graph, a primary page entity, and FAQ markup |
Connected Organization, WebSite, WebPage or Article entities with appropriate properties |
| FAQ presence | Whether pages contain identifiable questions and answers | A visible, non-duplicated FAQ that answers real follow-up questions |
| E-E-A-T | Authorship, dates, organization identity, technical trust, brand pages, citations, credentials, and content maturity | Named responsibility, current dates, clear company identity, and checkable evidence |
| Multimodal content | Useful images, video, charts, tables, and descriptive alternatives | Media that explains or proves something, with accessible context |
| Section length | Whether sections are developed enough to answer one idea without becoming unwieldy | Focused sections that can be retrieved as coherent passages |
These are diagnostic rules inside GEOCARA's scoring model. They are not secret Google ranking factors and no individual sub-score guarantees an AI citation. Google states that content used in its generative search features must meet the same fundamental Search eligibility requirements and that there are no special additional technical requirements for appearing as a supporting link (Google Search Central).
How the GEO Authority Score is calculated
For the free public checker, the eight site-level sub-scores receive equal weight:
GEO Authority Score = sum of the eight sub-scores / 8
The result is rounded for display. A score should be interpreted as a diagnostic baseline rather than a probability. For example, 70/100 does not mean a website has a 70% chance of being cited. It means the audited sample satisfied more of GEOCARA's defined readiness criteria than a site scoring 40/100 under the same model version.
For E-E-A-T, the current model combines four layers:
| E-E-A-T layer | Weight | Examples of signals |
|---|---|---|
| On-page responsibility | 30% | Author identity, publication or update date, Organization markup |
| Domain trust | 25% | HTTPS, robots.txt, sitemap discovery, schema diversity |
| Brand identity | 25% | About, team, contact, and recognized entity references |
| Content maturity | 20% | Depth, external evidence, citations, and relevant credentials |
This layered approach prevents one author byline or one schema block from being treated as complete evidence of trust.
How recommendations are prioritized
Recommendations are generated from the measured gaps, not selected from a fixed generic checklist. They include the current sub-score, the number of affected pages, and up to five example URLs when page-level evidence exists.
- P0 identifies blockers or major content usability gaps that can prevent retrieval or useful extraction.
- P1 identifies important structural and evidence improvements, including weak schema, missing direct answers, low information density, or poor section development.
- P2 identifies supporting authority and polish improvements that should follow the higher-impact work.
Priority is not the same as implementation cost. Removing an accidental crawler block may be a fast P0 fix, while improving thin content across dozens of pages can require a larger editorial project.
What the checker does not measure
The free readiness score does not directly measure:
- whether a brand is mentioned for a particular prompt today;
- share of voice against named competitors;
- sentiment inside an AI-generated answer;
- the number of citations received from each platform;
- organic keyword rank, search volume, or backlink authority;
- user engagement or conversions after an AI referral.
Those outcomes require recurring prompt probes, search-console data, analytics, or backlink data. The guide to checking AI visibility explains how to combine these evidence layers without turning them into one misleading score.
Data handling and repeatability
Public grader results are cached for a limited period to avoid repeatedly crawling the same website within a short window. A later run can differ because the website changed, the selected page sample changed, a server temporarily failed, or the scoring model was updated.
GEOCARA versions its public grader model so benchmark reports can use a consistent cohort. Aggregate research excludes domain names and contact details. The 2026 AI Visibility Readiness Benchmark publishes the sample size, date range, model version, aggregation rules, and limitations alongside the results.
FAQ
Is the GEO Authority Score a Google metric?
No. The GEO Authority Score is a GEOCARA diagnostic metric. Google does not publish an equivalent 0-100 AI visibility score, and the number should not be presented as a Google ranking or endorsement.
Does a high score guarantee a ChatGPT citation?
No. A stronger score means the audited pages expose more of the structure and evidence GEOCARA tests. Actual citations also depend on query relevance, retrieval systems, external authority, competition, freshness, and platform-specific behavior.
Why does the free checker analyze only five pages?
Five pages provide a fast, no-sign-up baseline while keeping the crawl focused. It is enough to expose common template and content problems, but it cannot represent every section of a large website.
Can two scans of the same domain produce different scores?
Yes. Content changes, crawl availability, page selection, model-version changes, and temporary rendering conditions can alter a result. Compare scores generated with the same model version and review the underlying recommendations rather than relying only on the headline number.
How often should a website be checked?
Recheck after meaningful technical or editorial changes, then use a regular monthly or quarterly cadence for stable sites. High-change publishing, ecommerce, or product sites may benefit from more frequent monitoring.
