I joined some LinkedIn groups for marketers to see if I could find some hidden gems, but the experience was largely unfulfilling due to recurring themes such as excessive noise, inactivity, low engagement, and cumbersome moderation. The experiment revealed that many groups were either too busy or too quiet, with few opportunities for meaningful discussion or interaction. As a result, my advice is to promote your own content by building a personal following through consistent engagement rather than relying on LinkedIn groups. This approach allows you to evaluate the quality of any traffic and streamline your marketing efforts more effectively.
