Podcasters copy each other. For example, it's common to see someone using certain equipment and, if you like the sound, buy that same equipment for yourself.
While it's helpful to emulate what works, problems arise when everyone copies each other and there's no innovation.
Take the story of the jeweler and the factory foreman; both set their clocks by each other, assuming the other is correct, but unaware if it actually is.
Podcasters can fall into this trap too.
A common example of this situation in the podcasting space is how we pitch podcast guests. Many "guest booking" companies use templates for their clients, which means thousands of similar messages go out to podcasters.
As podcasters, we see these pitches, assume they're working, and copy them for ourselves.
And the cycle repeats itself.
Copying others is great, but make sure what you are copying is working. And never make the assumption that something working for others will also work for you – always test.
