Does ghostwriting include editing?

It depends on the package you choose or your talk with the ghostwriter. Because ghostwriters offer many packages, and it also depends on the type of content you want. Like if you hire ghostwriting agency online to write blog posts or articles then the perfect written content is included in the service and the ghostwriter has to edit the content to make sure that it is written perfectly. While for other services like if you hire them to write a whole book. Then editing might cost you additionally after writing. So, you should talk clearly to the ghostwriter about the editing service.
