question about traffic estimates for broad match
hi all, i have one question regarding keyword planner's ”get traffic estimates for a list of keywords” feature using broad match.
Let's say I want to know the impression of the two phrases.
(this is just an example)
In cases like this, I noticed the impression estimate of "Japanese food" sometimes is bigger than "Japanese".
I thought broad match will take into account both impressions of "Japanese" and "Japanese food", so the impression of "Japanese" should be larger than "Japanese food".
Could somebody teach me why it is not working this way and the opposite? Thank you very much in advance.
