Podcast tracking is improving, but not super useful yet in many cases. It works best for advertisers with high LTV products that can be tracked via coupon codes or memorable vanity URLs. A lot of advertisers actually shy away from them because they try to charge high CPMs without great tracking, which is important when their reach is so low comparatively so other statistical methods aren't as useful for measurement.
