According to Google trends, the search volume is gradually going down
And we can compare the impact of Album 5's promo and DALS on public using this graph. The peak to the left of the graph is "5" and the two on the right are premiere and winning of DALS. Note that this graph shows only the last 12 months. (the rectangle in pic below)
When looking at the recorded past, DALS is about 40% of Psych volume,
though it looks even smaller, so that's good enough
. And MCE and Gourm are not recorded (the steep slope at the beginning).
People getting used to follow her through social media rather than searching for news in google, over time, might be a cause for the gradual decrease in the long-run.
I might sound pessimistic pointing these things out, and I don't even understand the mechanism behind the Google trends (all I know is that 100 is the maximum volume recorded and the rest is being compared to that) but I thought this was worth posting in here.
