This only helps the heavy handed SEO optimized sites with deep pockets and time to kill get yet another edge.
The article with the best insight isn't likely to be the one with the perfecly optimized website.
I understand that pagespeed effects end user experience when they hit a website, however that's not what I searched for. I did not search "fastest website with okay knowledge about dogs" I asked for "website with the best knowledge about dogs".
I want Google to be able to show me the most awesome page about dogs. The most in depth and relevant information. That niche dog blogger who is so passionate that they spend all their time researching dogs. I don't want "10 cool facts about dogs by Buzzfeed".
