Podcasters should be consistent to promote their podcast. The best way is to share little cuts or highlights in the social media, join different podcast communities, and ask listeners for reviews. You can also promote your podcast by collaborating with other podcasters or bringing guests who often feature the episode with their audience members. Making little snippets for TikTok or Instagram can also help you get new listeners. Promotion is not about shouting, it is about showing them what they miss.
I think most of the podcasters gain momentum by using social media, TikTok and Instagram reel in particular. It has helped to generate curiosity and compel individuals to listen to the podcast. They use brief clips on social media to capture the attention of people.
Promotion is most effective to reach out to your audience in a real way. Requesting reviews and feedback will also provide real time interaction as well.
