Hello,
I used the Keyword plan flow to Generate historical metrics.
I called keywordPlanCampaigns:mutate with this an input:
[{"create":{"keyword_plan_network":"GOOGLE_SEARCH","geo_targets":[{"geo_target_constant":"geoTargetConstants/1021048"}],"keyword_plan":"customers/xxx/keywordPlans/xxx","name":"campaign xxx","language_constants":[],"cpc_bid_micros":"1000000"}}]
Geotarget location is 1021048 - Charlotte, North Carolina, United States.
For this input, I got 40500 Search volume. That search volume looks strange. I tried the same setup for location 2840 - the whole United States and I got the same Search volume.
It looks like you have some fallback to the location - United States.
I tried the same setup at Keyword planner and got different results.
Why did this happen and how can I fix it?
Thank you
