Today I want to talk to you about DAI, or Dynamic Ad Insertion. DAI is a way for you to automatically insert ads (or any audio clip) into your already produced podcast episodes. There are lots of services that allow this, like Transistor and Buzzsprout, which makes it super easy. The way it works is this:

1. You upload your episodes
2. You upload the audio clip you want dynamically inserted
3. You mark whether it’s a pre-roll, post-roll, or mid-roll ad You can also (based on the service) set an expiration date, or manually turn it on or off. This allows you to do a few things, but the two I’m using it for are:
4. Selling a limited run ad-campaign (so a 30 day mid-roll on specific episodes)
5. Dynamically changing my call to action depending on the time of year. I got the latter idea from my guest Sam Munoz . Most of the year, I’m promoting my newsletter (this very newsletter, in-fact). But when there's some time-based event or special, I’ll be promoting that instead, without have to re-edit every episode. 

What do you think of DAI? Can you see it being useful for your podcast?
