Solo SaaS founders wear every hat, and content marketing is usually the first thing that falls off the plate. Writing SEO blog posts that actually rank means keyword research, competitor analysis, drafting, and consistent scheduling, all of which take time a one-person team does not have. SEO Content Planner is built for exactly this person. It generates SEO-optimized blog posts that target the keywords a founder's competitors already rank for, then schedules them out so publishing happens on autopilot. The MVP is narrow on purpose: connect a founder's site, point at one or two competitor domains, pull the keywords those competitors rank on, cluster them into a content calendar, generate drafts, and queue them for publishing. Revenue is a straightforward subscription: a monthly plan tiered by number of posts generated and competitors tracked, likely landing in the 29 to 99 dollar range that solo founders will expense against their own product budget. Go to market leans on the same channels the target audience already lives in: Show HN launches, indie hacker communities, and building in public where the founder publishes their own SEO wins as proof. Growth loops come from the output itself. Every post the tool generates can carry a subtle 'planned with' footer, and founders who rank from it become case studies that feed the next wave of signups.
