Hi
Google Trends is a tool offered by Google that helps you track and analyse the popularity of search queries. It is quite simple to use. All you've got to do is go to the
Google Trends website and enter a topic that you want to analyse the popularity of.
You can find out how its popularity has ranged over a period of time and how it ranges across different geographical locations. You can also compare the popularity of two or more topics!
It's a great way to analyse your audience and even discover new niches. You can also find out the most popular product trends and analyse the popularity of your competitors.
Hope this helped.
