That’s the same with a lot of hype in SEO circles. It’s the usual loud voices making a big deal out of it, but when you get down to the actual practicalities, not much changes.

Not least because very little of it is conclusive in terms of what Google do and don’t use, weightings, etc

It’s most valuable because it shows up a lot of googles public statements where they’ve said they don’t even consider certain things, with this implying they very definitely do in some capacity

Yeah people are acting like everyone needs to scramble to take advantage of this, but it's mainly not actionable to improve your own rankings.

If you're a black hat then I guess making your clickfarms spend more time on your site might be useful now, but if you are playing by the book then continuing to make good content that people want to read remains the most important factor.
