Is there a way to automatically get Google Trends comparison of two keywords?
I am able to downlaod relative interest for specific keywords and locations by using the gtrendsR R package. However, I would like to systematically compare two keywords.
This is important because of the two-step normalization procedure that Google applies to its relative interest index. The picture below shows what I am aming at.
When you download data normally on R with google trends, your keywords should be normalized together
