Other than the index data, there's something even bigger.

Google's biggest PR success is convincing everyone that the quality of web rankings depends almost purely on algorithms. It does not. What allows Google to hold their monopoly is the $100s of millions (or more) they continuously pay to amass more manually created training data:

A new search engine could appear today with algorithms 10x better than Google, but without access to this scale of training data, their rankings wouldn't even be close to Google's quality.

Google maintains their position by paying cash for this monopoly on training data made by tens of thousands of $9/hour workers, not through superior algorithms!
