There number of Ecommerce CMS available in the market like Magento, Open Cart, WordPress-WooCommerce etc.
Magento is one of the most popular and widely used CMS for ecommerce websites.
It supports almost all the functions related to the ecommerce websites like offers, discount, payment integration using all the available methods etc.
It has been very flexible for the catalog maintenance, because we can create all types of products using magento backend.
WordPress–WooCommerce is good for the small ecommerce websites having less than 300 products in the store.
I have listed some of the ecommerce concepts,
- Google Shopping – google displays top products based on their index and rule to their shopping page. In order to display your product you need to have semantic SEO implemented on your website.
- NextTag – seems to be shopping websites which selling products of other website and having price compare option.
