【LLMO Diagnostic Tool】Mesut Tools Launches May 31: Scoring Websites on AI Citation Potential

Mesut Inc. (Headquarters: Shinjuku, Tokyo; Representative: Kohei Uda) launched 'Mesut Tools' on May 31, 2026, a free AI Search Optimization (LLMO) diagnostic tool designed for the generative AI search era. Users can simply input an article URL to receive two core functions: 'LLMO Site Diagnostic,' which scores the likelihood of the site being cited by AI on a 100-point scale, and 'Entity Diagnostic,' which determines if the company/brand is recognized as a formal entity on Google Knowledge Graph and Wikidata. The tool is available for free with no registration required.

The key feature is the implementation of the proprietary citation-oriented algorithm, 'CITE Score (Citation-oriented Index by Tuned Entities).' This model is not based on 'leaking Google's hidden mechanisms' but rather reconstructs citation improvement strategies verified by Princeton University's GEO paper (KDD 2024) and public knowledge bases like Google/Wikidata into a 100-point evaluation formula, providing a transparent and reproducible scoring model.

■ Development Background: From 'Being Searched' to 'Being Talked About by AI'

Generative AI platforms like ChatGPT, Claude, Gemini, and Perplexity are becoming the 'first entrance' replacing search engines. Instead of clicking on ten blue links, users now read a few lines of summarized answers cited by AI.

This shift silently but fundamentally undermines the premises of traditional SEO:

- Even with top keyword rankings, if not cited or mentioned within AI responses, content never reaches the user.
- AI selects sources based on 'Entities' (who, what, and how reliably it is talked about in context) rather than simple 'keyword matching'.
- Consequently, many companies suffer opportunity losses without realizing how they are perceived and portrayed by AI.

Today, companies need tools to 'measure, break down, and improve' their 'AI Citation Strength (LLMO)'. Mesut Tools was developed to provide a reproducible ruler for this invisible metric.

■ Overview of the 'CITE Score' Algorithm

The core of Mesut Tools is the 'CITE Score,' which calculates how much AI 'wants to cite' a page based on seven layers totaling 100 points:

【CITE Score 7 Layers (100 pts)】
- Layer 1: LLM Extraction Optimization (26 pts) - Writing style optimized for AI citation.
- Layer 2: Entity Connection (20 pts) - Connection as an entity on Google KG/Wikidata.
- Layer 3: AI Crawler Access (15 pts) - Permissions for 17 types of AI crawlers.
- Layer 4: Structured Data (13 pts) - JSON-LD implementation for AI interpretation.
- Layer 5: Author/Operator Profile (11 pts) - Clarification of E-E-A-T.
- Layer 6: Brand Citation (9 pts) - Contextual appearance of brand names.
- Layer 7: Freshness Signal (6 pts) - Clarity of information updates.

In addition to this 100-point 'LLM Citation Strength,' the tool measures traditional SEO signals on a separate 100-point axis to determine an overall grade from S+ to D.
