I listened to a podcast earlier today from Christopher Penn and John Wall (Marketing Over Coffee … my favorite marketing podcast) and the discussion revolved around blogging, new media, podcasting, etc. Nothing really new there.
The little twist that Mr. Penn threw in, that I thought was interesting, was consciously infusing your podcasts with keywords and phrases. The logic is that your cast may be quoted or, in part, transcribed back into text-based mediums. When this happens, your cast will likely be found by surfers using those keywords. This is indeed an interesting little twist on how to view your own content creation.
So, instead of simply interviewing people or randomly talking for the sake of creating a podcast, you should include podcast keyword/phrase preparation as part of your entire content creation strategy … which is, of course, a part of your overall written marketing plan.
