Choosing the right template & SEO

Hello all,

I'm new to squarespace. I have worked with Wix but some friends told me that Square Space rocks.

So I need a website that allows me to give classes (pre- recorded videos) and sell learning modules. Eventually pretty much in the same line of Udemy or Linkedin Learning.

I went through the available designs and FAQs but it's difficult to decide and I don't want to change afterwards.

Additionally, would like to ask how efficient is the SEO using a website from SquareSpace? Good results?

I'm going to need a lot of SEO and want to be sure that it's fine.

Thank you very much in advance.

Best regards,

Antonio Ferreira
