My job is to write algos that optimize the bid on behalf of clients.

Most pay per click ad platforms have an API that let you set the bid.

I also work in this field,

> Most pay per click ad platforms have an API that let you set the bid.

even when you are let to set the bid, usually the auction is not conducted just based on your bid but also adjustments from the probability that you will actually pay out

Right, this is why I said it's not strategy proof.

The bid is just an input you control into an opaque function where the output is some cost and conversions

I’ve been a buyer for 8 years are so on ttd and another dsp but haven’t heard of the probably of paying out thing - can you share more info on that?

If you are bidding on a pay per click basis, typically your bid will be adjusted to expected revenue based on the probability someone actually clicks on your ad. For CPM ads this probably doesn't apply.

This is not for open web exchanges, referring more to stuff like adwords, facebook, etc.

Ah shoot that makes sense I was so confused. I was thinking for programmatic the ssp was reducing a bid based on whether they expected the advertiser to actually pay haha

i phrased it poorly
