RanketAI Self-Measurement Case Study
D → C grade progression in 25 days (2026-05-01 ~ 2026-05-25)
RanketAI measurement results (evidence)
RanketAI measurement — 2026-05-21 (grade · confidence · grading basis)
RanketAI measurement — 2026-05-25 (grade · confidence · grading basis)
Key takeaways
- • D → C one-tier progression in 25 days
- • Progression via own media only — no earned media yet
- • Next tier requirement = earned media (external authority sources)
Timeline
| Date | Grade | Cited responses | Progression note |
|---|---|---|---|
| 2026-05-01 | D | 0 | Baseline — brand not mentioned in Perplexity answers |
| 2026-05-21 | C | 4 | Brand mentioned in Perplexity answers — 4 citations from a single glossary page (ai-search-visibility-tool) |
| 2026-05-25 | C | 6 | Citation expanded in Perplexity answers — 3 from glossary + 3 from blog explainer = 6 total (DefinedTermSet schema + menu IA reorganization) |
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.
2026-05-01 → 2026-05-21 (D → C, 4 citations gained)
- • 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
- • Menu IA reorganization (Content → Insights) — asset category cohesion

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 auto-injection rolled out across all glossary pages (applied to 24 glossary entries with FAQ sections). The schema change occurred after the 5.25 measurement, so next-issue citation variance must be evaluated as a schema-injection effect — not a page-body change.
- • Change log — 2026-05-26: Sentiment algorithm fix applied (negation invalidation, sentence-bounded window, English word-boundary guard). Sentiment data inclusion reconsidered from next issue.
