Prompt folder promotion

#1
Hi. Please tell me there is (site.com.ua / city) selling building materials. Created two subfolders as two different sites for two cities. A question from the main page (site.com.ua) needs to put links from the footer to cities. Or whatever you recommend. Promotion for Google. Thank you.

I don't quite understand what exactly you need. Are there two language versions of the site and need to promote them? Just fill up with quality materials and Google will drive traffic to relevant pages.
