www.brandname.com is a Rails app hosted at Heroku. brandname.wpengine.com is a Wordpress blog hosted at WPEngine.
I know I can't use the DNS (CNAME) to map www.brandname.com/blog
to brandname.wpengine.com
.
I may map blog.brandname.com
to brandname.wpengine.com
instead.
But I've read many posts about subfolder and subdomain and the impact on SEO. Sometimes it seem it doesn't matter, sometimes it does.
So, what about a rack redirect ni the rails app? Someone as answer a similar question here: https://stackoverflow.com/questions/17327761/make-an-existing-wordpress-blog-a-subdirectory-of-a-rails-app
What do you think ? What is the best way to link a Heroku app and a WPEngine blog to maximize SEO?
blog.brandname.com or rack redirect?
Cheers
