Google has deprecated the desktop Web. It's still here, but for Google it just got less important.
At least that's the implicit message in Google's recent mobile search update. The company is now judging how "mobile-friendly" a site is and is using that metric to weight search results served to mobile devices.
This is the third update in Google's slow push for Web developers to start building mobile-friendly sites. First, Google announced that it would start calling out sites that used Flash and at the same time rewarding mobile-friendly sites. Initially, that was just a little label next to search results on mobile devices that told viewers the site was "Mobile-friendly".
Now mobile-friendliness has moved from visual alerts and promos to affecting actual page rankings.
