What changed (reproducible patterns)
Concrete actions RanketAI took to progress D→C in 25 days. A reproducible pattern using own media only (glossary · blog), without earned media.

- • Glossary cluster cross-link reinforcement — 9 explainer articles bidirectionally linked (ko/en)
- • Explainer semantic domain magnetism — 'AI visibility measurement tool' category definition authority page (ai-search-visibility-tool) made citable
2026-05-21 → 2026-05-25 (4 → 6 citations expanded)
- • Glossary GNB promotion — first-level menu exposure for discoverability ↑
- • DefinedTermSet schema added — explicit category definition authority signal to AI answer engines

Measurement methodology
This measurement follows these principles.
- • Tool: RanketAI's own measurement tool (dogfooding)
- • LLMs: Major LLMs (ChatGPT · Gemini · Perplexity)
- • Prompts: Diverse intent-based combinations
- • Grades: 6 tiers (A / B+ / B / C+ / C / D)
Limits
- • Measured target = 1 domain (RanketAI self). Category sample expansion from next issue.
- • Perplexity single-platform citation confirmed (other LLM citation measurements in next issue)
- • This issue focuses on citation counts. Sentiment analysis is excluded due to high per-measurement variability — multi-measurement averaging will be applied from next issue.
- • Change log — 2026-05-26: FAQPage JSON-LD structured data was automatically added to 24 glossary pages that include FAQ sections. This benchmark was measured on 2026-05-25, so the change is not reflected in this issue. If citation counts change in the next issue, we will separate the effect of body-content edits from the effect of structured-data additions.
- • Change log — 2026-05-26: The sentiment analysis logic was updated. The fix reduces cases where negated phrases are incorrectly read as positive and focuses sentiment checks around the sentence where the brand is mentioned. Sentiment analysis is not included in this issue and will be reconsidered from the next issue.
