I am developing a website using a ghost theme, which have only blogs, about us page, and contact page. The homepage is listing of all blogs. So, I am confused if I should have segment blog in url to look like example.com/blog/sample-slug or example.com/sample-slug is fine  ? How would this affect SEO  ?
