On a side note, there are two types of automated bidding tools from Google. One is called just “automated,” and the other is called “smart.” The key difference is that smart bidding can set different bids for every auction, thereby taking the real-time QS factor into consideration and setting “smarter” bids that are more likely to match the advertiser’s target.
Does "smart" bidding calculate QS any differently than Renkbrain or at least have defined variables?
