While there are a handful of reasons why I don’t generally think that Squarespace is the best option as website/blogging platform, the main issue I have with Squarespace is the same as I have with sites like Blogger, and far outweighs things like not having full control over your design. (Although, I think that’s a pretty big issue too, let’s be real.)
The simple fact of the matter is, with sites like Squarespace and Blogger, you don’t own your content. Which is why it blows my MIND to see so many businesses on Squarespace.
Now to be clear, if you’re a new blogger and you’re just getting your feet wet, great! Explore every possibility there is, make sure you find what’s right for you, and that blogging is something you’re going to stick with before you invest a ton of money into something. We all started out somewhere and there’s always possibility and room for growth to a self-hosted solution in the future.
For a business though? Come on, now.
