I have created HostForward, a service that now offers an easy, no-code way of running your blog (Ghost, Wordpress etc, or any web service) on a subdirectory of your website to reap the SEO benefits. For example:
blog.example.com -> example.com/blog
It doesn't need to be a blog, it could be a support site, documentation site, shop etc. It just needs to support being run in a subdirectory. Any main website/domain is supported.
Previously you would have needed to configure a reverse proxy server to do this.
I'd like to offer the Indie Hacker community 10% off any plan - just quote "HACKER10" on sign up.
