User Acquisition Strategy

Search-led, no paid ads. The demand already exists as queries — "youtube playlist to notebooklm", "how many sources can notebooklm take", "telegram export to notebooklm" — and the incumbents rank on thin authority, so a listing plus a few editorial pickups is enough to compete. Four channels, in order of effort/return: 1. Chrome Web Store listing SEO. Day zero, free, highest intent: people who search inside the store are already installing something. 2. Owned pages and articles, one per search intent. 3. Communities where the question is already being asked — the method first, the link second. 4. Third-party listings, roundups and Show HN. AI answer engines are the fifth surface: the same articles written as plain factual sentences with FAQ markup, measured monthly against a fixed prompt list. Deliberately not doing: paid acquisition, build-in-public grinding, cold outreach at scale, and lifetime-deal coupon ladders — the pricing is one flat $29.
