Build a content idea bank from my customers' real questions

Build an idea bank for my content from what my customers actually say. This is step 1 of a 4-step content engine pack; later steps (weekly anchor piece, batch production day, monthly review) can use this idea bank. Audience: [WHO] Content pillars: [LIST - or "suggest groupings"] Raw material: [paste any mix of: sales call notes, support tickets, customer emails, reviews, comments, forum threads, survey answers, questions from webinars] What I sell: [PRODUCT/SERVICE] Steps: 1. Extract every distinct question, complaint, objection, misconception, and "how do I..." from the raw material. Keep the customer's own words. 2. Cluster them by pillar and by buyer stage: unaware of the problem, exploring solutions, comparing options, using the product. 3. Turn each into a content idea with a working title, the angle (how-to, myth vs. reality, story, comparison, checklist, teardown), and the best format. 4. Score each idea 1-3 on: how often it came up, closeness to a buying decision, and my ability to say something original. Return: 1. A table: Idea title | Customer's words (quote) | Pillar | Stage | Angle | Format | Score. 2. The top 10 to make first. 3. Gaps: stages or pillars with few ideas, and where to listen next to fill them. 4. A simple way to keep adding to this bank weekly (a capture habit and template). Only use quotes that appear in my raw material; don't invent customer language.
