Important: the .ORG version of WordPress is the one you download and install on your web server, and is the fully-customizable version of WordPress.
I love WordPress, but I’m the first to admit that it is a hammer in search of a nail. WordPress is hefty, and can do a tonne of different things (there is quite literally a theme or plugin for anything). The million dollar question is do you NEED wordpress? And the answer to that is what do you NEED from your website; do you need complicated content types and relationships, advanced eCommerce, fine-grain control of users and user roles, complex online forms? If you answered NO to the above maybe give Squarespace or Shopify a try first. The power of WP really shines in its ability to do whatever you want. But this comes with a larger upfront pricetag, and potential security risks (WP powers a huge percentage of websites, and is thus a prime target for hackers).
Shopify is a Canadian business forging way ahead when it comes to eCommerce. While both WordPress and Squarespace can sell your products, Shopify makes it easy to set up and run, and does so VERY well. Shopify maybe isn’t as flashy as Squarespace, it does have some really nice themes to build a cool online store. But make no mistake – Shopify is here to start an online store – the website creation is a little basic compared to Squarespace.
Squarespace is a website creation service that helps you build your site quickly and easily with their very user-friendly visual drag and drop interface. With Squarespace they offer a total package, you can even register your domain name through their service. It’s relatively affordable, and the templates are absolutely stunning – plus, it offers basic eCommerce for those looking to sell online.
