All podcasts will include audio ads, either pre-recorded or a live host endorsement. They are placed at the beginning (pre-roll), middle (mid-roll) and end (end-roll) of the show.

As part of an advertising package, podcasters can offer you graphic banners in the sidebar, show notes, in the footer, etc. in all different sizes.

As part of their offering, many podcasters will mention and link to you on Facebook, Twitter, Instagram, Pinterest, or wherever their community and your audience hang out.

If the podcast has a healthy blog, they may consider including some dedicated blog posts as a part of your ad package. This could be as a review, or they could allow someone from your company to write a piece as well.

Email is a great way for you to get in front of your podcast partner's audience. They may link to you in their emails, include a graphic banner, or perhaps dedicate an email every so often to your company and it's benefits.

Many podcasters speak all over the world, and/or host events for their podcast. You could sponsor or co-host these events, or you could have logo placement on any podcast branded materials they take along with them.
