A focus group is a qualitative research strategy used to elicit detailed insights and opinions from a small, varied group of people on a given topic, product, service, or issue. An online focus group, also known as a virtual focus group, is a sort of focus group that takes place over the internet. 

When in-person meetings are not possible or practicable, an online focus group discussion can be a useful tool to address concerns and enable participation. Here are some tips for organizing and leading a successful online focus group discussion:
