I really like Google’s Zeitgeist site, it gives insights into top searches and provides several ways to look at top them. You can find which are the top ones worldwide, and also break them down by country and region. You can also find the top 100 fastest rising queries. This is such a useful and powerful tool for marketeers that I recommend spending the time to review it. Click on the link to go to the 2013 Zeitgeist site. (opens in a new tab).
