Unomas LLC (Location: 2-2-15 Minami Aoyama, Minato-ku, Tokyo; Representative: Ono) has officially launched "AI Compatibility Score" (https://unomas.jp/ai-checker/), a free tool that can comprehensively diagnose the LLMO (AI Search Optimization) and SEO readiness of websites.
By simply entering a URL, the tool automatically analyzes 6 categories and 23 items in as little as 30 seconds. It presents two indicators: "AI Citation Potential Score (out of 65 points)" and "SEO Foundation Score (out of 35 points)," instantly displaying a total score out of 100, a grade from A to E, and the top 3 priority improvement items. It requires no registration, is completely free, and supports sending a PDF diagnostic report (approx. 16 pages) via email.
■ What is AI Compatibility Score?
AI Compatibility Score is a free diagnostic tool that automatically analyzes a site from both AI and SEO perspectives by simply entering a URL, and visualizes the results as a score. The diagnostic results display the following two types of scores:
【(1) AI Citation Potential Score (Total 65 points)】
Composing categories: Structured Data (25 points)・E-E-A-T (20 points)・AI Crawl (20 points)
Composed of 3 categories directly linked to being "cited/recommended" by generative AI search engines such as ChatGPT and Perplexity. These are particularly important indicators for advancing AI search countermeasures (LLMO).
【(2) SEO Foundation Score (Total 35 points)】
Composing categories: Basic SEO (20 points)・Site Speed (10 points)・Security + Mobile (5 points)
Composed of 3 categories for improving evaluation by traditional search engines like Google and enhancing site reliability and comfort. This visualizes the completeness of the SEO foundation, which serves as the base for AI search countermeasures.
The total score is calculated by summing (1) + (2) to 100 points, and is presented along with the top 3 priority improvement items.
■ Background: The spread of AI search makes "creating sites that get cited" a new essential requirement.
With the rapid spread of AI search engines such as ChatGPT, Perplexity, and Gemini, "zero-click searches" are increasing, where AI generates answers before users view search results. In such an environment, whether a company's site is cited in AI's answers has become a new competitive axis that affects organic traffic.
However, there was almost no objective means for especially SMEs, professionals, and clinics to check "whether their site is compatible with AI search." Existing SEO tools for large companies lack LLMO compatibility indicators, and diagnosis itself is difficult without specialized knowledge.
■ Differentiation from competing services: 3 unique features
▶ The only free tool that can cross-diagnose LLMO and SEO in one tool:
Many existing tools specialize in SEO diagnosis (title, meta, speed, etc.). The AI Compatibility Score uniquely adds 3 categories directly linked to optimization for AI search engines (LLMO): "Structured Data, E-E-A-T, and AI Crawl." The biggest differentiating point is its ability to diagnose LLMO and SEO comprehensively.
▶ A unique composite index: "AI Citation Potential Score":
Beyond mere pass/fail judgments for items, its unique scoring design separates "AI Citation Potential Score (65 points)" and "SEO Foundation Score (35 points)," allowing for simultaneous visualization of priority issues on both LLMO and SEO fronts. The combination of speed diagnosis via Google PageSpeed Insights API integration and free provision of an approximately 16-page PDF diagnostic report is a differentiated point among similar free tools in Japan.
▶ Just enter a URL, approximately 30 seconds, no registration required:
Designed with priority on ease of use, allowing instant diagnosis without specialized knowledge. It also integrates with Google PageSpeed Insights API to accurately obtain external data for site speed (LCP, CLS, TBT). Free email delivery of a PDF diagnostic report (approx. 16 pages) is also supported.
