I'm setting up a wordpress site with a domain of let's say "domain.com". On that site there are Pages like "domain.com/productA" and "domain.com/productB", which are also linked to by the main menu.
I also own the domains "productA.com" and "productB.com"
What I want to achieve is that when a visitor navigates to the productA page through the menu, that the address bar displays "productA.com". The same should happen when a visitor types "productA.com" in the address bar.
I know that some of this is possible with multisite and domain mapping, but the product pages should still be conained in the main site, sharing things like header and menu, which would be complicated using multisite, or am I wrong?`
Lastly: Does this even make sense? Does this have any positive or negative effects on SEO? Would you advise just redirecting to the main domain?
