Do I need to include the name of the city in the query if targeting the whole country?

Question

contextual advertising

Good day!

There are two phrases "buy a pen" and "buy a pen in Minsk". Both are in the same group. It is clear that it is worth doing cross-minus. Promotion region: all Belarus.
Q: Do I need to include a city name query if there is a common query and both are in the same group?

Answer 1

Google doesn't make much sense. Moreover, within the group you will not do cross-minus.
In Yandex, you can select individual requests only to make a more targeted ad and a more accurate bid in order to occupy a specific position.
