Google Trends is a tool that allows you to see how often a particular search term is entered into Google search over a specific period of time and in a specific location. It can be a useful tool for market research because it allows you to see the relative popularity of different search terms, which can give you an idea of consumer interest in a particular product, service, or topic.

To use Google Trends for market research, follow these steps:

1. Go to the Google Trends website (https://trends.google.com).
2. In the search bar at the top of the page, enter the search term or terms that you want to research. You can enter multiple terms separated by a comma to compare their relative popularity.
3. Use the filters on the left side of the page to specify the time period and location for your search. You can choose a custom time period, or select a predefined range such as “Past 12 months.” You can also choose to see search data for a specific country, region, or city.
4. Once you have entered your search terms and set your filters, click the “Go” button to see the results.
5. The results page will show you a graph of the search volume for your search term or terms over time. You can hover over the graph to see the exact search volume for a particular day.
6. You can also use the “Related Topics” and “Related Queries” sections to see what other topics and queries are related to your search term, which can give you additional insights into consumer interests and preferences.
7. If you want to see more detailed data or customize your search further, you can use the options in the “Explore Data” section on the right side of the page. This will allow you to view data for different time periods, locations, and categories, and to see how search trends have changed over time.

By using Google Trends, you can get a sense of how popular a particular product or service is, and how that popularity has changed over time. This can help you make informed decisions about your marketing strategy and product development efforts.
