I saw that wordpress has a lot of different plugins for SEO so I was thinking that would be a big plus for it. I was not sure about the other CMS website softwares.I have read before that the CMS does not matter for the SEO of a website and I have also read that it does so I don't know for sure. I know that I see things all the time that says that wordpress is real good for SEO without much setup and that's what I use.
I know there are some like wordpress that have plugins to help the SEO of your website so you will probably be ok with any of the good ones.
Isn't woocommerce just for selling things on your wordpress site?I suggest WooCommerce, which is a free WordPress plugin and one of the fastest growing shopping carts. More small businesses used WooCommerce for their online store
