Once you release a podcast episode, you'll obviously want to share it on social media. However, you cannot forget that you're competing with a lot of noise on Twitter. Nonetheless, I still see plenty of Tweets like this:
Our latest podcast is now available! Check it out - (Link)
Episode 52 of the show is out now - (Link).
My initial response is...so?
I don't know anything about that episode. Plus, if this is the first time I've seen your podcast, you just lost a chance to intrigue me. Just like other forms of content (blogs, video), you need to post something that might get me or someone else to click on it. An episode number or simply saying, "check it out" isn't going to be enough for most people.
Use hashtags, images or clever text to draw attention to your latest episode.
I'll give you a personal example. When I was first learning how to do this, I posted a generic Tweet about my latest episode. As you can imagine, it didn't get much response. Then I thought I would highlight something specific that might get people to click on the link.
This episode featured an interview with Anthony Michael Hall, and he had some interesting things to say about playing Kelly LeBrock's love interest in Weird Science. So, I tweeted about that (in some fashion), and it got a much larger response. In fact, it got Kelly LeBrock's attention as well. She began following the show on Twitter.
So, don't share meaningless episode numbers or generic call to actions. Get attention and intrigue the audience! If I can help your podcast in other ways, contact me anytime!
