Is it necessary to indicate the region in which services are provided in the title?

Question

Search Engine Optimization

There is a small corporate website with standard pages (about the company, services, sub-services, contacts) and a small product catalog.
So is it necessary to indicate at the end of each heading the region in which services are provided?
For example: Delivery of drinking water to Mars or Drinking water "Phobos" on Mars ?
Does this affect output in any way? There are no competitors in the region and so far only companies with the ability to deliver "to Mars" are popping up, and the client provides a full range of services in this region directly from the supplier, etc.
I feel that this has been discussed many times already, but a cursory search did not return any results :(

Answer 1

The more accurately the title matches the search query, the higher the link ranking. Those. You have nothing to lose in the case of the usual Water Delivery request, but you gain a lot in the case of Water Delivery to Mars.
