I am looking for someone with strong Magento SEO experience, but I am unsure how to evaluate different experts objectively. One person may focus heavily on content while another talks mainly about technical fixes, and both claim they can improve organic visibility. For a store with thousands of products, which areas should a proper SEO assessment cover? I would like to understand what information a specialist should request, what problems they should identify, and what a useful action plan should look like before any major changes are made.
