The audience is being ignored.
If you don’t know the type of people that should be listening to your podcast, it will be hard to grow as a podcaster. Initially, it might be hard to find your footings when you launch your first few episodes. The problem might be with the topic of your podcast, your reaction to your current audience, or you do not know who your target listeners are. Lack of feedback to the audience is how podcasts fail.

Solution? Master The Art of Communicating With Your Audience.
Your audience should be left, right, and center of your show. Carve a niche for yourself. Use a process of trial and error to find the majority of your audience base. Give feedback to every review, especially if you have only a small number of listeners. Create shows with your audience in mind. Make it worth their while. Encourage them to like, share, and comment on your podcast on the major podcast directories such as Apple Podcasts, Spotify, and YouTube.

Lack of Consistency.
Most podcasters quit after the first three to seven episodes. Starting a podcast and not sticking to a schedule is how most podcasts fail. You probably expect to succeed after you have published your first few episodes. However, you published an episode on Monday this week, posted another on Tuesday the following week, and then waited a whole month before you dropped a new episode. It shows a lack of commitment and consistency.

Solution? Stay Focused and Committed.
Whether it is a daily, weekly, or monthly episode, you cannot have loyal fans without a working schedule. If you promise to update bi-weekly, then you must deliver. Podcasting requires a lot of work. Before you record, edit and publish, other things in your life might get in the way. Get a co-host or an assistant if you cannot do it alone. Use automation software. More importantly, tell your audience about any change in your schedule.

Lack of Authenticity.
About four million podcasts are released monthly, listened to by 116 million people. Do you think they've never heard what you are going to say before? Think again. If you drone on and put your audience to sleep, or you imitate what others have produced without any originality, you are going to lose listeners fast.

Solution? Be Original.
What differentiates you from the other podcasters is HOW you deliver your content. If the absence of originality is how podcasts end, create a well-produced show that is unique, effortless, and relevant. The timbre of your voice and the way you sound will determine whether you are enjoying your show or it is only superficial. Work with what you are passionate about. Listen to great podcasts in your niche and learn what sets those podcasters apart.

Mediocre Marketing.
Your podcast passed the soundcheck, the content is quite creative, and you consistently publish a new episode, say weekly. You have been a podcaster for six months now, but you have only five listeners with two feedbacks. Lack of adequate promotion is how podcasts fail. No matter how great your show is, if you do not market it to your audience, they will not discover you.

Solution? Promote Your Podcast.
Make a video and audio version of each podcast episode—post video teasers on social media. A great free tool to use? Headliner.app Use word of mouth. Note that these solutions will only work for you if you know your audience. You do not need every listener in the world, just those who share your interest. Also, mediocre shows that don't create value will not sustain the momentum even if people temporarily listen to them. What is the purpose of your show? Is it to inform, entertain, educate or enlighten?
