Is it reasonable to make landing pages a subdomain or a subdirectory of the main site?

Question

Search Engine Optimization

Roughly speaking, instead of http://buy-this-wonderful-crap.rf and http://Roga&Hooves.rf make http://buy-this-wonderful-crap.Roga&Hooves.rf.
Motivation:

• you need several landings (or their analogues) and there is no certainty in how many and which ones;
  
• the desire to save on domains with limited funds;
  
• the desire to easily change the structural logic of the site (s).

The question is speculative. The real task is not yet worth it.
Will such a solution still give some kind of output in search engines, as well as in attracting / encouraging customers, or does it completely eliminate it? Will there be any difference between a subdomain and just a directory?

Answer 1

It doesn’t matter, you can create a path for landing pages /promo/vasha-kakashka
and that’s all, why are you worrying about this?

Answer 2

It’s somehow stupid to save on them at a price of one hundred rubles

Answer 3

for the PS it will be the same thing, so that the so-called. seo-shniks)))
so we stock up on 190r and go ahead, buy domains.
it’s clear that it’s a toad, but if you set a goal, then here’s my personal experience - once, the other day))), I look, BEGETA has shares - domains for 65r! Well, why not buy 4-signs like twenty pieces?))) I bought it))) half have been hanging with a plug for half a year already, there is no time, the main thing is to grab it on the cheap (the principle of a typical US resident? I'm getting ready slowly)))

Answer 4

subdomains are considered a separate site of the
subdirectory - part of the site
in total, 10 landings on subdomains will not affect the main site in any way
10 landings on subdirectories will give the site its weight and requests (that is, landing on Christmas trees on the subdirectory of the site on lanterns will tell the search engine that the main site is about Christmas trees and lanterns ).
And vice versa! That is, a new site about sleds in the subdirectory will be considered part of the already promoted site, which has now begun to trade sleds.
