Sitespeed is all about user experience. With some incredible Lighthouse insights, tips and tricks, Wili makes me go all starry-eyed about Lighthouse (pagespeed 3.0). He follows that up with a few super lessons in HTTP2, and tells me that speed as a ranking factor is an illusion. Also, by the way, Google wants to be a librarian and Fili owes me TWO Lego men :)
