stop auto-bidding on mdsp. one sneaky trick to RON with 100% roi

It seems that lot of people will use the auto bidder function on mDSPs when they RON as part of the placement discovery process.
i use to do that, and my RONs had -50% roi at best.

Then i decided to do a little coin math. let’s say you have a 2usd payout offer. your creatives have a ctr of about 2%. and your lander should convert at about 2%. what cpm do you have to pay to make 100% roi?

1000 impressions x .02 ctr x .02 cv = 0.4 conversions every 1000 impressions. or 0.8 usd per 1000 impressions.

so paying 0.8cpm, you will break even and a 0.4cpm you will make 100% roi all else being equal ...
