Codex Build Packs

These are not keyword reports, but minimum site-building packs that can be handed directly to Codex to start work.

1. Sample size calculator matrix for surveys, A/B testing, and preclinical studies

• Representative keyword: sample size calculator
• Product format: tool
• Buildability: 64 / 100
• SERP gate: -
• Monetization: B2B leads and subscriptions: drive traffic to survey tools, questionnaire platforms, and A/B testing tools; premium features include project saving, report export, team templates, API.
• Main risk: If statistical formulas, confidence intervals, power analysis, and applicable scenarios are handled incorrectly, trust will be directly damaged.

Codex Task

# Project: Sample size calculator matrix for surveys, A/B testing, and preclinical studies
Build a small SEO-friendly web experience for `sample size calculator`.

## Goal
Two calculators: survey sample size calculator and A/B test sample size calculator; output formulas, parameter explanations, copyable reports, and CSV export.

## Pages
- /sample-size-calculator
- /sample-size-calculator/examples
- /sample-size-calculator/faq
- /sample-size-calculator/alternatives

## Requirements
- Make every claim source-backed when factual or regulated.
- Include FAQ and breadcrumb schema where relevant.
- Add a visible last-updated timestamp.
- Keep the first version narrow enough to ship in 1 week.

## Monetization
B2B leads and subscriptions: drive traffic to survey tools, questionnaire platforms, and A/B testing tools; premium features include project saving, report export, team templates, API.

## Acceptance Criteria
- Responsive pages render without login.

• Total opportunities: 10
• Build now: 0, do this week: 2, watchlist: 6, reject: 2
• Priority formula: Business value (40%) + competitive space (30%) + trend strength (20%) + execution speed (10%)
• Model summary: Most candidates in this pool are sports, entertainment, brand navigation, product purchase, broad generic terms, or copyright/gray-area download terms, and have been downgraded according to hard exclusions; the retainable opportunities are concentrated in clear tool loops: image processing, statistical calculation, AI prompt optimization, storyboard template generation, and video transcription; none are suitable for blindly heavy investment, so prioritize low-cost validation pages and tool MVPs

Full Candidate Pool Key Opportunity Details

1. storyboard template

Do this week | score=64 | work hours=10h | confidence=medium

One-sentence conclusion: Suitable for quickly building a template library + online generator; the goal is not to explain what a storyboard is, but to let users generate PDF/PNG templates.

Strongest counterargument: Storyboard That, Canva, and educational resource sites already have strong pages, and simple template downloads are easy to commoditize.

Positive opportunity:

• Why it is worth doing: The loop of template download, online editing, and PDF/Figma/Slides export is clear, and it can be expanded into industry long tails.
• Evidence: In the input, keyword=storyboard template, source=root_top, root=Storyboard, related_value=91, pre_llm_reasons=weak_intent,task_closure; the same pool includes what is a storyboard and storyboard that.
• SERP weakness: -

Keyword and Search Intent Table:

Product Format Judgment: template_library

• Task closure: high
• Related keywords: storyboard template, what is a storyboard, storyboard that

MVP Plan: Select 3/6/9/12-panel storyboard templates online, supporting landscape/portrait, A4/Letter, note areas, and PDF/PNG download.

SEO Page Structure: Homepage targeting storyboard template; long-tail pages covering blank storyboard template, printable storyboard template, video storyboard template, animation storyboard template, comic storyboard template; embed the generator on every page.

Monetization Design: Ads + paid template packs; premium features include watermark removal, brand styles, batch export, classroom packs, Figma/Google Slides/PPT export.

• Monetization basis: signal_weak

Validation Plan:

• Launch the template generator and 12 static template pages in 7 days; add Google Slides/PPT export in 14 days; evaluate download rate, email subscriptions, and paid template clicks after 30 days.

Abandonment Criteria: If the download rate is below 10% within 30 days, or search impressions are concentrated on definition terms rather than template terms, stop expanding the template matrix.

Confidence Level: Medium

• Main risk: Templates are prone to sameness, so differentiation needs to be built through scenario-based templates, online editing, and export formats.

2. sample size calculator

Do this week | score=64 | work hours=12h | confidence=medium

One-sentence conclusion: It is worth building a professional but lightweight calculator matrix, starting with survey sample size and A/B test sample size.

Strongest counterargument: Universities, statistics tool sites, and survey SaaS providers already offer similar calculators, so the head term may not be easy to rank for.

Positive opportunity:

• Why it is worth doing: This is a clear, reusable, non-hype professional calculation task, suitable for building a vertical calculator matrix.
• Evidence: In the input, keyword=sample size calculator, source=root_suggest, pre_llm_reasons=strong_tool,task_closure; it belongs to strong tool-intent calculator.
• SERP weakness: -

Keyword and Search Intent Table:

Product Format Judgment: tool

• Task closure: high

MVP Plan: Two calculators: survey sample size calculator and A/B test sample size calculator; output formulas, parameter explanations, copyable reports, and CSV export.

SEO Page Structure: Homepage targeting sample size calculator; subpages covering survey sample size calculator, ab test sample size calculator, proportion sample size calculator, margin of error calculator; use formula explanation pages for internal linking.

Monetization Design: B2B leads and subscriptions: drive traffic to survey tools, questionnaire platforms, and A/B testing tools; premium features include project saving, report export, team templates, API.

• Monetization basis: signal_weak

Validation Plan:

• Launch 2 calculators and 4 formula explanation pages in 7 days; add PDF/CSV export and email capture in 14 days; test affiliate link clicks, report export rate, and saved-project registration rate after 30 days.

Abandonment Criteria: If the calculation completion rate is below 35% within 30 days, the report export rate is below 5%, and there are no B2B/education backlinks or inquiry signals, pause.

Confidence Level: Medium

• Main risk: If statistical formulas, confidence intervals, power analysis, and applicable scenarios are handled incorrectly, trust will be directly damaged.

• arbitrage calculator | this_week->watchlist | tool->tool | high->medium | kill_reason=Downgraded from this_week: intent is not narrow enough, and finance-related results require real-time data and compliance boundaries.
