How to promote by SEO and not duplicate in the search results: the main page, the root page of the product catalog, the description page about the manufacturer?

Question

Search Engine Optimization

Tell me how to position pages with duplicate information for Yandex? What texts to write on these pages?
What requests and pages should I bring users from the search to?
Do users need a “manufacturer description” page? Or is it already outdated?
Home: http://legrand.bel/
Product catalog page http://legrand.bel/series/
Description of the manufacturer whose goods we sell: http://legrand.bel/legrand

Answer 1

It would be better to start with semantics and define landing pages based on demand. Instead of creating a page, and then not knowing what to do with it.
If you do without semantics and proceed from logic, then the main one should be focused on requests:
legrand belgorod
buy legrand
outlets legrand
To the catalog page:
catalog of outlets legrand
legrand price
And do the page about the company: a description of the manufacturer and you, as a distributor, why it is worth buying exactly you.
Collect semantics, cluster and distribute requests across pages, see how competitors implement it and do better. Here is the recipe for perfect SEO.
