Let's get real for a minute.
Do you like when people come to your door to try to sell you something?
Do you enjoy when you're walking along the street and someone stops you to try to get you to take their flier or get you into their store?
Do you like pop-up ads?
Then stop spamming your podcast!
Here's the deal — I know your podcast is probably great. Your audience likes it. You're probably getting feedback from your listeners. But if you're constantly (keyword here is "constantly") throwing out your latest episode link on social media, to your friends, family, in your groups and all over the place, it may get you a few more listeners, but it's also going to annoy more people.
