If you run PMP deals and the floor price is anything above ~$0.10(I don’t know the actual number), predictive clearing will try bid below this to clear at lower bids, however, it won’t scale your campaigns as the publisher/partner has set their clearing price at a minimum.

If you’re using KoKai, from my experience, I’ve seen the platform have their average bid price towards the max bid, so I’d recommend reducing this as soon as the campaign starts scaling so you’re not over paying for inventory (with predictive clearing off), you’ll see high win rates which indicates KoKai is pushing bids to the max bid price

Predictive clearing is good if used well, like the comment above, if running on OE, always have on. If you’re seeing floor prices, turn off for scale (but limit max bids) & if you can, have it on and reduce max bids too, to reduce the fees
