I am working on a startup project in the e-commerce space. We'd like to have a landing page, blog and help center hosted on the Webflow CMS. But we're also developing a booking system using our own framework, hosted on our own VPS.
The booking system will be accessible through a subdomain, something like: 'bookings.domain.com'
But the thing is: Someone recommended us to have all content located on the same domain. According to him, using subdomains for important content (like product pages) is not ideal and will not have the best SEO value.
What do you guys think about this? What would be the best approach here?
