What is a niche forum?
A niche forum targets a specific group of people. Rather than spinning around broad interests, specialty gatherings home in on a particular theme in a way that is immediately pertinent to individuals they're attempting to target.
The simplest way to find your niche forums is by searching on Google. Type in your niche keyword with “forum”. For example, if you're in the travel business and specialize in Dubai, search “Dubai travel + forum”.
