Full Candidate Pool Decision Dashboard

• Total opportunities: 14
• Build immediately: 0, build this week: 4, watch: 9, eliminate: 1
• Priority formula: Business value (40%) + competitive space (30%) + trend strength (20%) + execution speed (10%)
• Model summary: Most terms in the full pool are news, sports, entertainment, brand navigation, e-commerce products, or generic red-ocean tool terms; retained opportunities are mainly concentrated in terms with clear tool loops, feasible long-tail matrices, locally completable tasks, or maintainable structured databases; however, no real-time SERP crawl was performed, so competitive judgments are conservative assessments based on keyword intent and input signals

Full Candidate Pool Key Opportunity Details

1. pdf to excel converter free

Build this week | Score=62 | Work hours=24h | Confidence=Medium

One-sentence conclusion: Viable, but the entry point should be “accurate table extraction, privacy, local/short-term deletion, and batch processing,” not a generic PDF converter.

Strongest counterargument: The PDF tools space is highly crowded, and the input shows pdf converter with metrics_kd=62, indicating generic terms are very hard to compete for.

Opportunity case:

• Why it is worth building: Office conversion tasks are clear and commercially valuable, and a free entry point can upsell batch/OCR/privacy value propositions.
• Evidence: In the input, pdf to excel converter free comes from root_rising, related_value=130, pre_llm_reasons=strong_tool,task_closure; pdf converter has metrics_volume=500000, metrics_kd=62, metrics_cpc=8.40, metrics_source=csv_exact, showing demand and commercial value exist, but generic terms are highly competitive.
• SERP weakness: -

Keyword and Search Intent Table:

2. sample size calculator

Build this week | Score=58 | Work hours=12h | Confidence=Medium

One-sentence conclusion: Suitable for building a high-trust, niche but stable calculator, then expanding into a statistical tools matrix.

Opportunity case:

• Why it is worth building: The calculation loop is clear, making it suitable as a trusted statistical tool and expandable into research/survey workflows.
• Evidence: In the input, sample size calculator comes from root_suggest, pre_llm_score=8, pre_llm_reasons=strong_tool,task_closure; no metrics_volume/KD/CPC.
• SERP weakness: -

Keyword and Search Intent Table:

Product Type Judgment: tool

• Task closure: high

Abandon Criteria: Pages receive traffic within 30 days but calculation completion rate is below 30%, or affiliate/export clicks are near zero.

Confidence Level: Medium

• Main risks: Formulas, statistical assumptions, and explanations must be accurate, otherwise trust costs will be high.

3. writing prompt generator

Build this week | Score=58 | Work hours=14h | Confidence=Medium

One-sentence conclusion: A lightweight generator is viable, but it must start from specific categories and a saveable prompt library, not a generic AI prompt generator.

Strongest counterargument: Content generation tools are everywhere, free AI chat tools already satisfy a lot of demand, and willingness to pay may be weak.

Opportunity case:

• Why it is worth building: The generation task is clear, and education, writing practice, and classroom scenarios can form a reusable template library.
