Content Optimisation Tools 2026

Content optimisation tools tell you exactly what to include in your content based on what's already ranking. They analyse NLP terms, word count, heading structure, and more. I've used Surfer SEO for 100+ articles and can tell you definitively: these tools work. The question is which one fits your workflow and budget.
