When Julia started her recipe blog in 2022, she did everything right — keyword research, quality content, proper on-page SEO. Eight months and 120 articles later, she wanted to know which posts were actually ranking. The cheapest option? Ahrefs at $99/mo — more than her blog's total revenue. She tried Google Search Console, but it only shows averages, not daily positions, and comparing against competitors is impossible.
The SEO tools market generates over $1B in annual revenue, dominated by Ahrefs ($100M+ ARR), SEMrush (public company, $330M revenue), and Moz. But 80% of their features serve enterprise users — site audits, backlink analysis, content gap analysis. For the millions of bloggers and small site owners who just need rank tracking, these tools are like buying a commercial kitchen to make toast.
SerpWatch, Nightwatch, and AccuRanker have nibbled at this space but all converge around $29-49/mo — still expensive for bloggers. The real opportunity is a $19/mo tool tracking 200 keywords daily with a gorgeous UI and dead-simple setup. SERPRobot proved $10K+ MRR is achievable at $5/mo per domain. Scale that to $19/mo with a better UX and you have a sustainable $30K+ MRR business.

📊 Market Evidence
The Market Gap
Ahrefs ($99/mo) and SEMrush ($129/mo) are overkill for small sites. AccuRanker ($116/mo) is enterprise. No one owns the $19/mo 'rank tracking and nothing else' niche with modern UX.
