How to promote a site with subdomains without duplicating content?

Question

Search Engine Optimization

Good day to all!
There is a site that we want to promote with subdomains (by region).
The site itself has a complex structure, a lot of unique content, etc.
It is planned to have about 25 subdomains.
The essence of the question:
How to create subdomains without having to write a bunch of unique texts for twenty-five sites (or duplicate existing ones)? If you implement it with landing pages, will it be a hat with seo?
If anyone knows a trick, please share.

Answer 1

If the texts are equally suitable for any regions, you can duplicate it, just be sure to specify your regions for all subdomains in the Yandex webmaster. Subdomains should have regional contact information, it would also be nice to make titles with descriptions relevant to a particular region.
For example, let's take Skoda dealer websites - the brand has a strict policy that prohibits the dealer from changing the content on the site. Dealers differ in contact details, promotions and news. Duplicate content does not prevent them from ranking equally well.
