I have a client that has a service in una supersmall city and when i search the service+city (example "plumber+verysmallcity" on Keyword Planner i find 0 searches.
There is a way to know how much people of this city search simply "plumber" on Google?
If i can't now, in this cases it make sense to do seo? I have just to do "standard seo" to gain the first page for all the country? (i live in a small country, it's not impossible to achieve the first page).
Thank you for your help!
