What do you like best?
I like the fact that it is free, easy to access and use, pretty informative, and not complicated. Everyone uses Google, what else can give such a valuable piece of information on the frequency of searches for an item/person.
What do you dislike?
It may not show the websites where the volumes of traffic are pretty low meaning that we can't really see the full picture, but just the tip of the iceberg.
What problems are you solving with the product? What benefits have you realized?
It helps understand what is going on in the world, what is trending, how people react to any world news, events, occurrences. I have realized that people are rather driven by their emotions.
