Two versions of the same page, how to implement?

Question

PHP

There is an online store. It is necessary to present a product card in two forms - standard and as a landing page. I don’t want to load all the information at once and change it through css / js, ideally there is an idea to make
subdomains for each product. How is it best to implement it, where to dig, what to read?
UPD: I asked incorrectly. The problem is how to automate the generation of such "doubles" in wordpress

Answer 1

Alternatively, write your own wordpress plugin.
Or like this:
For the domain promo.mysite.ru/shop/example there will be a landing page for the product example. Hang up your routing on promo., and you can pull product data through api (there is such a plugin for WordPress).
In my opinion, such a system is the most optimal.

Answer 2

the dumbest option in the forehead - A / B Google test :)
