How to host blog on separate domain from main site

Assumption 1

Wrong. I have a couple of WordPress installations in subfolders, some redirected to sub-domain, some not. If you set up the setting properly, there isn’t any issue with this.

Searching for “problem + WordPress + subfolder” will lead to some questions, that turn out to be having rewrite rule problems.

Assumption 2

If you are relying on SEO factors purposed by websites such as WooRank, then you shouldn’t really bother. These services offer some good recommendations, but their methods are not “Divine”. Search engines are smarter than what they were a decade ago.

You’re not going to lose 50% traffic just because you choose to use blog.example.com over example.com/blog.

What if your site is a blog itself? should it have another example.com/blog? No.

Assumptions 3

You can go either multisite or two individual installations. Multisite offers some features, such as shared users data, which you might find useful.
