Two sites with the same content, how to promote?

Question

Search Engine Optimization

Manufacturing company. There is an office in Moscow, a website (the same domain.ru), advertising, everything. Production is carried out in another city (Arkhangelsk, if important), another site (same-domain.com), another advertisement, another office.
But the content of the sites is duplicated. The sites have a microdata with the corresponding addresses, there is a page "About the company" with the same details.
Is it necessary to make one of the sites the main one in this case, or is it possible to inform the search engines in some other way that this is the same organization?
hreflang is not suitable, since everything is within Russia.
The task is as follows - for residents of Arkhangelsk and the region, the Arkhangelsk site should be shown, for residents of other regions - the Moscow site.

Answer 1

Very simple.
Register sites in the Yandex directory and specify the address of the organization. By the way, do not forget to completely fill out the profile of the organization, this is important.
In Yandex Webmaster, specify the regional affiliation of each site and the problem is solved.
Video instructions for adding to the directory here .
As for Google, there is no corresponding section in the Search Console (there is, but you can only specify the country). Therefore, the region must be specified in Google Business . Also try to fill out the profile 100%, it is important in promotion and display on maps.
By the way, you can read about how the rating of an organization in the directory is calculated on the Yandex blog .

Answer 2

No way.
And there was no point in making 2 sites.
Highlight some aspects tied to geography - yes.
But it makes no sense to make separate sites, despite the fact that you cannot make them very different.

Answer 3

Not an expert, but I guess:
msk.site.ru
arh.site.ru
and redirect from .com

Answer 4

two CEOs from my team are confidently and SUCCESSFULLY promoting three similar projects, branches of Moscow + St. Petersburg + Ekat, The bottom line is that subdomains are made for each city and
the Second essence - respectively, on each of the subdomains DIFFERENT headers, basements, contacts, in goods DIFFERENT blocks with text like "Delivery in your city blablabla tomorrow, from 8-00 to 18-00. Write blabalbla to Vasya Sidorov, contacts such and such. Address such and such."
The third essence - content pages (which the site moves on its own) - have slight differences - inclusions in the text indicating the name of the city - implemented programmatically)))
In a circle - the content seems to be the same and the products are the same, but if you look carefully, there are differences in details. What do we know about the details? The devil is hiding in them!

Answer 5

For Google, you need to implement one of the sites as a subdomain, that's all. In Yandex, there should not be any special problems if you fill out 2 organization cards on the directory.
