Cons
  • No public pricing - enterprise quoted
  • Scale-justified: overkill for a single small site

  • Full pricing requires a sales conversation rather than published tiers
  • Combined scope adds more surface area to learn than a single-purpose tool
  • Newer GEO features are less battle-tested than the platform's core SEO tooling
