How to promote the site in several cities of the Far Eastern Federal District at once?

Question

Search Engine Optimization

What is the most effective way to promote a commercial site in several cities of the Far East?
There is no office, the business coach works throughout the Far East.
This method comes to mind.
1. We assign the region "Far East" to the site. We create a "sales training" section, optimize it for the geo-dependent request "sales training".
2. We create subsections "sales training Vladivostok", "sales training Khabarovsk", etc. and optimize for the corresponding geo-independent queries.
How effective will such a method be in competition with sites with subdomains for cities (for example, "khabarovsk.<main domain>") for each individual city of the district?

Answer 1

Just like in the far east, where did you get the idea that there will be some differences then?
