I will use Shopify to build an fashion e commerce site, have several questions .. 1, when it comes to SEO result, is it the same for Spotfire and website made by developers? I donot want to buy a cheaper site but, in stead, I need to spend more time and effort to get the same SEO result. 2, can I easily switch my site from Shopify to my own site building by developers with the same domain if my business grows and I have money to hire someone to do customized design for my site? Thank you!!
