We have a Shopify store and a Wordpress CMS site. Currently the shop is on the root domain and Wordpress is on a subdomain (help.domain.com). Everything is fine, life is good.
Our SEO company, predictably, is now asking us to merge the Wordpress side at help.domain.com into the root by installing Wordpress in a subfolder.
Is it even possible?
My understanding is that such an architecture introduces a slew of technical issues and potential headaches.
I suppose my question is how big of a challenge is this and what types of issues should I expect to face. Moreover, does the benefit outweigh the cost.
You cannot make WP a subdirectory of Shopify. You must continue to keep it as a subdomain. So while your Shopify can be domain.com, your WP must continue to be something like help.domain.com.
Your SEO company is flailing at windmills. Not unusual. If they were good, you might instead be receiving advice on how to leverage the content of your domain as a total package, rather than how you choose to organize it. The organization in terms of domain setup is so not important compared to the content within.
