On a periodic basis I use the Google Hot Trends Gadget to view the most popular searches on a given day.  Based on the Google Trends service, a popular search term is analyzed based on a variety of factors.  In addition, users can compare the volume of searches between two or more terms and analyze web searches across various regions of world.

Overall, Google Trends is a decent resource for Internet Marketers or Search Engine Optimization junkies.  If you’re looking to increase website traffic or analyze specific search patterns, Google Trends is a good place to start.
