Question 2

How does auction-time bidding (used in Google's smart bidding) differ from traditional rule-based bid adjustments?

Accepted Answer

It evaluates dozens of real-time signals for each individual auction

Auction-time bidding evaluates real-time signals such as device, location, time, and search query at the moment of each auction to optimize the bid.

Question 3

What is the primary purpose of setting a bid floor in programmatic advertising?

To set the minimum price below which an impression will not be sold

A bid floor is a minimum price set by publishers; impressions are not sold to bids that fall below this threshold.

Their ads appeared 60% of the time they were eligible to show

Impression share is the percentage of eligible auctions in which your ad was actually shown, out of all the auctions it could have appeared in.

Impression Share Lost (Rank) specifically shows the percentage of eligible impressions lost because your Ad Rank was not high enough.
