I’ve been involved in web dev in different forms for 20 years, but I’ve never done anything with these types of websites.

My questions are:

* When you register a domain with them, is the domain legally yours?

* Are there any SEO penalties for using these apps to build websites? Does anyone own a website or client site hosted on Squarespace or similar that’s ranking high on Google?

I can see the benefit for developers but I’m wondering about the benefits for clients.
