The cost of Amazon SEO starts from around INR 8000, but may increase based on specific requirements, goals, and products of a business. Apart from SEO-specific factors, such as the number of keywords and backlinks, content requirements, and keyword competition, the cost also majorly depends on the number of products a business offers. Doing SEO for a higher number of products will cost more as compared to the cost of optimizing one or two products for Amazon.
