Hot Trends reflects what people are searching for on Google today. Rather than showing the most popular searches overall, which would always be generic terms like “weather,” Hot Trends highlights searches that have sudden surges in popularity. Our algorithm analyzes millions of web searches performed on Google and displays those searches that deviate the most from their historic traffic pattern. The algorithm also filters out spam and removes inappropriate material.

For each search, Hot Trends shows related searches, a search-volume graph, and the top cities. We also display news, blog, and web results to help give context about why a search may be appearing on the Hot Trends list today.
