This is important because before you go writing sales copy and multiple articles you want to understand why the niche is interesting to others. This will help you to narrow and define the hot spot in a much more precise way.
To do that, there are several places you can go to get some additional information on your hot topics:
This is a great tool setup by Google to focus on the trends happening in a particular segment. It allows you to see how the search volume is trending over the years. The best part of this tool, however, is the ability to put multiple hot topics in (separated by commas) and then be able to compare the volume trends per year in comparison to both. This way you can determine which one is actually the best hot topic, based on whether it shows it is trending upwards and how it compares to the search traffic of different hot topics.

This uses the Yahoo! Search engine functionality to return hot topics based on what’s being searched there. You will see some top searches displayed as well as up and coming hot topics. You can also plug in your own terms and see what people are saying about that. It is located at: http://buzz.yahoo.com
