Why Free SEO Software Matters
Free SEO software packs a punch. No licence fees. Full data control. Custom tweaks. Perfect for SMEs with tight budgets. You host it yourself. You own every log file. You decide every update cycle.
But there’s a catch. Many open-source tools demand technical chops. Some lack fancy AI. Others need manual reports. What if you want the cost benefits of free SEO software plus a dash of machine learning magic? Hang tight. We’ll cover nine top open-source platforms and then show you how CMO.SO bridges the gap.
