It takes a team to make a podcast. It may just look like it's one or two hosts who are completing the tasks associated with keeping a podcast running but everyone has a team behind them. Sometimes it's friends and family but many times it looks more like having an editor, a manager, or a full team of professionals to keep things running smoothly.
As of this year, there are over 2 million podcast shows currently available. Sitting down to record, talking for an hour, and publishing your show as-is isn't enough to stand out anymore. Starting strong with a clear vision and with a well-produced podcast should be a top priority for new podcasters. Quality in content and in audio are core parts to this. Don't try to reinvent the wheel, guarantee a strong start by hiring experts to work on your production.
