Cons

- Significant Learning Curve: The depth and breadth of features across SEO, AI search, accessibility, and site speed can be overwhelming, requiring meaningful onboarding investment before teams realize full value.
- Requires Demo/Sales Contact for Pricing: Lumar does not display transparent pricing publicly; prospective customers must book a demo or contact sales, which slows down the evaluation process for teams comparing tools.
