Our large e-commerce platform, built on a custom framework, is experiencing stagnation in organic search visibility. We require a highly skilled technical SEO specialist to conduct a deep dive audit. This includes crawlability, indexability, site structure, core web vitals, schema markup, and mobile friendliness. Deliverables are a detailed report with prioritized, actionable recommendations and an implementation guide for our development team. Extensive experience with large-scale e-commerce SEO is mandatory.
