My take on the leaked docs. We don’t know if this is for production or for testing. My guess is it’s mostly for testing potential changes. We don’t know what’s used for web or for other verticals. Some things might only be used for a Google home or news etc. We don’t know what’s an input to a ML algo and what’s used to train against. My guess is clicks aren’t a direct input but used to train a model how to predict clickability. (Outside of trending boosts) I’m also guessing that some of these fields only apply to training data sets and not all sites. Am I saying Google didn’t lie? Not at all. But let’s examine this leak objectionably and not with any preconceived bias.
