Depending on what tech you're using, there may be some simplistic analytics you can bake in with some packages.

Generally I'd recommend having some very basic analytics set up within your product, and allow the ability for easy integration with analytics providers for your users to do it themselves if they want more in-depth info.

E.g. BearBlog has builtin support for Fathom analytics, but you can do whatever you like with other platforms too.
