Formula Used
1. Topic Demand
Topic Demand = Pillar Search Volume + (Cluster Pages × Average Cluster Search Volume)
2. Ideal Cluster Pages
Ideal Cluster Pages = max(4, ceil(Pillar Search Volume ÷ 1600) + ceil(Keyword Difficulty ÷ 18))
3. Coverage Ratio
Coverage Ratio = (New Cluster Pages + Existing Supporting Pages) ÷ Ideal Cluster Pages
4. Content Depth Ratio
Content Depth Ratio = Actual Total Words ÷ Ideal Total Words
5. Authority Score
Authority Score = 1 − (Authority Gap ÷ (Keyword Difficulty + 15))
6. Ranking Readiness
Ranking Readiness is a weighted score using coverage, depth, linking, authority, technical quality, freshness, backlinks, and intent alignment.
7. Adjusted CTR
Adjusted CTR = Target CTR × Ranking Readiness × Technical Score × SERP Retention × Cannibalization Retention
8. Estimated Conversions and Revenue
Estimated Conversions = Estimated Clicks × Conversion Rate
Estimated Revenue = Estimated Conversions × Average Conversion Value
9. Timeline
Timeline Weeks = Total Project Hours ÷ Weekly Content Hours

FAQs
1. What does this planner calculate?
It estimates pillar page readiness, cluster coverage, internal linking needs, expected clicks, conversions, revenue potential, production hours, and a practical publishing priority.
2. Why are cluster pages important?
Cluster pages strengthen topical coverage, create contextual links, satisfy narrower search intents, and help the main pillar page earn stronger semantic relevance.
3. What is ranking readiness?
Ranking readiness is a weighted planning score. It combines authority, content depth, cluster support, technical health, backlinks, freshness, and intent alignment.
4. How should I choose target CTR?
Use your historic organic CTR by ranking band, intent, and SERP type. Informational pages usually perform differently from commercial or branded pages.
5. What does SERP feature loss mean?
It models traffic lost to ads, featured snippets, maps, video packs, or other results that reduce standard organic clicks.
6. Why include cannibalization risk?
Closely overlapping pages can compete against each other. The risk field helps reduce projected CTR when intent mapping is weak.
7. Can I use this for existing content hubs?
Yes. Enter current supporting pages, realistic authority, and refresh intervals. The planner will show gaps and improvement priorities.
8. Are these results exact forecasts?
No. They are structured planning estimates. Use them for prioritization, scoping, and scenario comparison rather than guaranteed outcomes.
