Reminds me I need to sell off my wordpress blogs

From personal experience:

The default theme 2014 works wonders SEO wise. It scored 56.5 out of 100.

A theme I contorted into what I need scores 52 out of 100 and I have many #1's in Google using it.

So that plugin is pure shit and won't help you at all.

If you want to rank, just use 2014 if you have no knowledge of how to play with themes.

What kind of sites?

Woothemes and Studio Press are both built on solid foundations. You can use these themes on standard web hosting packages.

Once you start getting into the fancy/bloated WordPress themes you need a powerful web server along with dynamic caching, memcache and HHVM or PHP 7.

Woocommerce requires a lot of power especially if you have multiple transactions at the same time.
