How to promote the regional subdomain Multisite?

Question

WordPress

Hello, can anyone help us with advice? We have a main domain with a physical office in St. Petersburg, we opened a second one in Moscow, we made a website like: msk.site.ru. The problem with the subdomain is not moving forward at all, it hangs at 30 positions and beyond. Contacts, directories, numbers are unique, prices are different, toponyms too, can someone tell me where to dig?

Answer 1

And where are you trying to promote the regional domain?. And for what queries do you have the top 30? Region or world?
Is the content unique? Website optimization? Search engine optimization? Analysis of your requests for unique count. checked per day? And a lot of other things can influence your positions in the search.
seo audit, analysis of promotion in the region, semantic core of the site
