Keep it short, but not too short. 2 minute pod casts are annoying. 2 hour podcasts are too long.
Follow a schedule – most of these guys just ramble, which leads to talking about how they’re rambling. Just don’t ramble.
Do not read to me. Talk, don’t read. This isn’t an audiobook. Unless of course, it is an audiobook. Then go ahead and read to me. Thanks.
Long intros/outros, especially if they’re just music, are annoying and serve no purpose.
Get to the point – don’t spend 5 minutes telling me what you’re about to tell me. Just tell me.
Make it available from places other than iTunes, including just an mp3 download from the site.
Don’t talk about Podcasting. Avoid the word altogether. Unless your podcast happens to be about podcasting. Then it’s fine with me, because I won’t be listening any way.
Have a website for the podcast, even if it’s just a simple list of the episodes. Sometimes podcatchers or RSS feeds get screwed up, and I don’t know if I have most recent show or not,
Make show notes available on the website you should have created for your show. This doesn’t have to be very detailed, just a list of links you mentioned in the show will do. I know of one podcast that makes transcripts for each show. That’s awesome.
Make ads interesting. If you preroll the same ads week after week I’m going to fast forward them. If you don’t know how to make an “infotainment” style ad, listen to a TWIT Network podcast or two.
Make every episode back to the first show available somewhere.
Stabilize the audio levels, especially if you record different segments in different places. I hate it when the volume goes up and down during a show.
