Running an eCommerce site from a shared host according to most isn’t recommended. Due to sharing it may result in your site running slower and therefore not giving your user the optimal experience.
Many Magento stores are recommended to use VDS plans or shared plans. But, this isn’t always necessary, consider the size and traffic to your site.
It goes without saying that if you do go shared hosting, pick a host who knows how to configure the server to run your Magento store and one who isn’t going to stuff one single serve to the brim with too many site.
