Podscribe calculates spend differently based on if ads in a campaign are episodic or dynamic.
Episodic Campaigns:
We apply all spend on the day the episode launches. If multiple episodes are matched to a campaign because ads were found in all of them, we apply spend to the earliest published episode matched to the campaign.
In the Overview tab, the spend for a particular date range would be the sum of the spend of the campaigns that have ads that came out within the date range.
If the first ad is found on YouTube, it is excluded by default from spend to prevent distortions to ROAS and CPA. But you can include it from the Overview tab:
Dynamic Campaigns:
For impression buys, we divide the spend pro-rated by day based on delivery. Eg if 10% of expected impressions come in day one, we apply 10% of spend on day one.
If only 90% of expected impressions are served by the campaign end date, we simply use the fraction of delivered (not expected) impressions each day. If > 100% of impressions are delivered, we cap the applied spend at the campaign's total cost.
In a perfect world, episodic buys would likely have spend pro-rated by delivery too. However, they also receive impressions indefinitely (as long as the ad stays in the episode), so a cap at 30-60 days probably makes the most sense.
