This refers to the positioning on the advert within an episode. In general, pre-roll means before the main content starts, mid-roll means during the main content and post-roll means after the content has concluded.
There are pros and cons to these three positions:
| Position | Pro | Con |
| Pre-Roll | Highest listen rate / Highest conversion rate | Most expensive |
| Mid-Roll | High listen rate / High conversion rate / More affordable | Does not maximise ad exposure. |
| Post-Roll | Most affordable | Lowest listen rate / Lowest conversion rate |
Ad positioning will often be determined by budget but the most effective, and thus the most common, is a pre-roll host-read ad campaign.
