AMP has caused quite the stir from a philosophical perspective, but the technology hasn’t received as close of a look. A few weeks ago, Ferdy Christant wrote about the unfair advantage being given to AMP content through preloading. This got me wondering: how well does AMP really perform. I’ve seen folks, like Ferdy, analyze one or two pages, but I hadn’t seen anything looking at the broader picture…yet.
How well does AMP perform in the context of Google search?
As Ferdy pointed out, when you click through to an AMP article from Google Search, it loads instantly—AMP’s little lightning bolt icon seems more than appropriate. But what you don’t see is that Google gets that instantaneous loading by actively preloading AMP documents in the background.
