The Trending searches page explained

The Trending searches page shows trending searches around the world. You can click on a story to get more context, like the most relevant articles or trending queries. Trending searches include Daily search trends and Realtime search trends as described below:

• Daily search trends highlight searches that jumped significantly in traffic among all searches over the past 24 hours, and updates hourly. You can use Daily search trends to see what people are most interested in at any given time, and how the searches rank compared to one another.
• Realtime search trends highlight searches that jumped significantly in traffic among all recent searches. The Realtime searches are collections of Knowledge Graph topics, Search interest, and Google News articles detected by our algorithms. The Knowledge Graph enables our technology to connect searches with real-world things and places. The algorithm for Realtime search trends groups topics together that are trending at the same time on Google News and Search, and ranks stories based on the relative spike in volume and the absolute volume of searches.
