Fascinating and useful tool for guidance of the topics that need covering out in the wider marketplace. As an agency partner, I find this useful and allows me to plan my future focus as well as areas to discover and build into if I were to be going down the website monetisation route.
I do use this in conjunction with Google trends, but google trends is not so Entity based as this is, which means, it amalgamates the results including all synonyms of the topic, its therefore more accurate.
As a digitial consultant, this leads well into the work I have done using the Inlinks suite of tool, my an essential tool for me for SEO.
