A Forum is a website community that allows users to post, search, and respond to posts. Forums are often designed around a very specific topic, such as C+ computer programmers or owners of a specific product.
Forums can be great locations to find information on specific topics or for finding people who are gathered around a topic, activity, or brand.
Marketers should be careful when posting to forums, so as not to create spam. Most forums do not provide follow links.
Reddit is essentially a series of forums built around themes.
