Welcome to the Q&A Forum

It supports to see time and time again is that someone has added some of social profile page URLs. What happens here is that whatever sites you listed are the ONLY sites that will be shown. So if you added your Facebook page, YouTube Channel page and Twitter page then only links to those pages will show up. You must make sure that if you add any URLs to this section in GA, you also include your domain and any sub-domains you may want tracked as well.

I suggest WooCommerce, which is a free WordPress plugin and one of the fastest growing shopping carts. Many small business used WooCommerce for their online store. They recognized that it allows them manage site with simplicity and SEO friendly. It is difficult to say that WooCommerce is the best SEO friendly CMS platform. However, I think it is a good solution for small business because of cheap cost and effectiveness.

If you are sure about WooCommerce and WordPress, you should try WooCommerce migration tool by Litextension to convert to new site with keeping SEO URLs. Check it: http://litextension.com/woocommerce-migration-tools.html
