> explicite feedback on SERP using "Block result from xyz site
I left it out intentionally. I feel that the signal is so small and noisey, that the value of it, must be limited. It's only value is in spotting stuff for hand checks. I don't believe it is going into the algo what-so-ever. Chrome has 5-10 million daily users. of those, there will be a pretty small percentage that have the extension, know what the extension is, and use the site block option on any kind of basis. It's main usage will be by competitors reporting each other. I bet there are less than 10k clicks on the 'block' button a day. The only place that is of value is in keeping the top searches clean via hand checks.
quiet the opposite and more of a nightmare really. I brought all this up, for the main reason of reminding people that what we think we know about the Google algo, is often 180 off. We can't assume we know anything without some empirical proof. That type of proof is next to impossible to work up in this day age. The data set is too deep.
