If you tell four random people you have a podcast, three of them will look at you blankly. That's because around 70% of the US population don't listen to podcasts. They are, you might say, clueless.
Keep that in mind when you are designing your promotional efforts -- a podcast page on your website, email newsletters, social posts, etc. And realize that maybe that high-paid podcasting consultant you hired (hi there!) may not have all the answers.
When it comes to promoting your show, you need to embrace the clueless.
Sure, it's important to follow best practices for engineering, production, distribution, and even content. And you very well may need some strategic help (hi there!) to make sure you've got all the bases covered.
But when it comes to designing promotional elements, are they "clueless" enough to speak the the three out of four people who'll see that promotion? Or are you better using a clueless-about-podcasting person (perhaps you) to evaluate those efforts?
