Reacting to EU’s opened a preliminary inquiry into competition complaints, alleges that Google operates without sufficient transparency into web sites rank. Matt Cutts says that “One of the most widely-discussed parts of Google's scoring has always been PageRank. That "secret ingredient" is hardly a secret. Here it is. That early paper not only gave the formula for PageRank, but mentioned many of the other signals in Google's ranking, including anchor text, the location of words within documents, the relative proximity of query words in a document, the size and type of fonts used, the raw HTML of each page, and capitalisation of words. Google has continued to publish literally hundreds of research papers over the years. Those papers reveal many of the "secret formulas" for how Google works and document essential infrastructure that Google uses. Some of these papers have spurred not only open-source projects but entire companies in their own right.”
