Google Trends

Google Trends is a useful and valuable tool for marketers and planners, allows them to see how popular specific keywords or subjects are over a period of time, and receive information about products, events, and services that matter most to their clients. The Google trends results are demonstrated through graphs; make it easy for them to view the distribution of changes in keywords since 2004.
Google Trends shows trends for your keywords by regional trends, related trends, top trends, rising trends, local trends, different categories, and it helps understand competitors and pay attention to and respond to shifts within the specific industry. It can also help you finding content ideas, and show you seasonal spikes and local differences for specific keyword.
In addition, since Google Trends doesn’t give actual numbers, it works best when used in combination with the Google Keyword Planner.
