I'm confused... How can the mode number of searches be 0.5?!
"More people perform half a search every day, than any other amount." -- What?!
I guess maybe that's more like "the mode over 30 days, divided by 30"?

That you would publish him... Well, that's your judgement but I consider it to be lacking.
Thus neatly showing how comment threads turn "pretty toxic". If you have better analysis of the data, that would be great to see.
And it is. According to his numbers, the mode is precisely 0. The most common number of searches is zero... more people do 0 Google searches in a day than do 7 or 1 or any other specific number.
This is not a USEFUL statistic, but (according to this data) it is accurate.
In order to get the mode, you'd need to know how many searches each person does each day. You can't get the mode from the figures he's been provided.
But in the article, he wrote:
"I tried modelling what search activity probably looks like on mobile: I used a mean = 0.925 (as per Singhal) and mode = 0.5. The mode must be below the mean because of the long tail of higher values; 0.5 is a guess, but moving it around doesn’t have a large effect. This gives a median of 0.94, close to the mean, which you’d also expect."
He made some guesstimates which he used as input parameters to form a Pareto Distribution.
As for the mode always being less than the mean, that's wrong too.
I was referring to the fact that the graphs - e.g. https://theoverspill.files.wordpress.com/2015/10/screenshot-... - are using using mode = 0.5
