Google offers a wide assortment of incredibly powerful tools and most of them are free for either personal or business use. One of my favorites that seems to be lesser known by a lot of people is their Trends tool. Imagine being able to leverage Google's incredible database of what people search for every day; that's what this tool offers! Knowing what people are searching for as well as the related terms that are used are incredibly useful for everything from Search Engine Optimization to every facet of digital marketing. The tool allows you to narrow the data by country, state, or even a specific language for the results. You can see how certain search terms have trended over time going all the way back to 2004. This is really useful when looking at the seasonality of certain types of searches, which is essential for building a solid marketing strategy. If you've never used this tool, it really is something you should explore for a variety of reasons, especially those that are in business: https://trends.google.com
