they care about how fast the pages load for visitors
given that google have said they place little score on how fast your page loads, i think thats it got more to do with how quickly the pages load for them (ie, google).
they have to spider the web every day. how expensive is that? and they have to store all the pages. how expensive is that? of course they are going to encourage us to get page weight down, because it will save them millions. all they've got to do is hint that its part of the algo and they know we will get straight on the job.
not that its a bad thing to get page weight and loading times down, or course. it benefits us too. i just think that its got more to do with saving them money than improving the serps.
