SerpStep launched after 3 months of solo dev, born from frustration: every SEO tool shows 47 metrics but none tells you what to do next. Today's launch: Keyword Opportunity (SERP analysis + difficulty scoring), SERP Explainer (why each page ranks and where it's weak), Content Brief Generator (outlines backed by SERP evidence), Idea-to-Keywords, and 20 supported markets. Free tier: 3 analyses/month. Next: competitor tracking and portfolio management.
