SEO experts say a massive leak of 14,000 ranking features exposes the blueprint for how Google secretly curates the Internet.

Maxwell Zeff:

Google Search is often referred to as the doorstep to the internet—it’s the first stop on most people’s journey to information online. However, Google doesn’t say much about how it organizes the internet, making Search a giant black box that dictates what we know and what we don’t. This week, a 2,500-page leak, first reported by search engine optimization (SEO) veteran Rand Fishkin, gave the world an insight into the 26-year-old mystery of Google Search.

“I think the biggest takeaway is that what Google’s public representatives say and what Google search engine does are two different things,” Fishkin said in an emailed statement to Gizmodo.
