On SEO: How I got 40 signups from one comparison page

Situation I launched a micro-SaaS with no audience and a generic landing page that ranked for nothing. Organic traffic was effectively zero after two weeks. Task I needed qualified visitors who were already comparing tools in my category, without paying for ads or writing fifty blog posts. Action I published one detailed comparison page against the two obvious incumbents, linked it from my footer and profile, and shared it in two niche communities with a honest pros/cons table. Result The page started ranking within ten days, brought 40 signups over the first month, and taught me that one sharp comparison beats ten vague feature lists.
