What to do (in terms of SEO) if the company is engaged in the same services in different cities?

Question

Search Engine Optimization

Good afternoon!
A very common situation: the company is engaged, for example, in the installation of windows in different cities.
And we need to promote the site with the keys "Installation of windows in Moscow", "Installation of windows in St. Petersburg", etc.
How to be in such a situation at the design stage? Should I write unique articles for each city or just replace the name of the city? Should I do everything on one domain or is it better to do cities on subdomains?
Thank you!

Answer 1

I would do it on subdomains. As for the articles, well, here we need a tricky combination where part of the article does not change and part changes ... Look at how competitors have done it.

Answer 2

It is better to do everything on one domain.
Cities - as categories.
Caps - corresponding to the cities.
Text - can be the same with the substitution of the name of the city.
Tags - cross-links to other information for this city.

Answer 3

I.catalog up to 7 regions allows you to choose. Make micro-markup, add trust addresses of the company, if the company is located throughout Russia, but there are no offices, then it will not be possible to fully promote it.
