Im not sure if this is the correct forum for this but I think it is.
I've decided for SEO purposes that I want a blog, selfhosted, and as a subdirectory. The only problem is that my server software for my e-commerce site doesnt allow me to install blog software. Is it possible to host the blog on another software but have it be a subdirectory of my current domain name? Also are there any alternatives to selfhosting if I want a subdirectory?
