It's possible things have changed since Cadwalladr wrote this last December.
How to bump Holocaust deniers off Google’s top spot? Pay Google
www.theguardian.com/technology/2016/dec/17/holocaust-deniers-google-search-top-spot
Until Friday. When I gamed Google’s algorithm. I succeeded in doing what Google said was impossible. I, a journalist with almost zero computer knowhow, succeeded in changing the search order of Google’s results for “did the Holocaust happen” and “was the Holocaust a hoax”. I knocked Stormfront off the top of the list. I inserted Wikipedia’s entry on the Holocaust as the number one result. I displaced a lie with a fact.
How did I achieve this impossible feat? Not through writing articles. Or shaming the company into action. I did it with the only language that Google understands: money. Google has shown that it will not respond to outrage or public sentiment or any sense of morality or ethics. It does not accept that leading people with a genuine inquiry about whether the Holocaust happened to a neo-Nazi website is grossly irresponsible or that it demeans the memory of the six million Jews who died. But it was prepared to take my cold, hard cash. A Google spokesman said: “We never want to make money from searches for Holocaust denial, and we don’t allow regular advertising on those terms.”
And yet, it has already made £24.01 out of me. (This was the initial cost – it has since risen to £289.) Because this is what I did: I paid to place a Google advert at the top of its search results. “The Holocaust really happened,” I wrote as the headline to my advert. And below it: “6 million Jews really did die. These search results are propagating lies. Please take action.”
I did this via Google’s AdWords programme. This is the bedrock of everything that Google does, its core business: selling ads against search results. It’s this that contributes the bulk of the $5bn (£4.07bn) profit that Google makes per quarter.
AdWords helpfully suggested possible “Ad group ideas” and search terms that included: “holocaust hoax”, “was the holocaust fake” and “did the holocaust happen”. And it told me how many searches a month are made for these terms: all in, 9,480. Or 113,760 a year. Or the population of Cambridge.
All of whom are being informed by Google that the Holocaust didn’t happen. And are being directed to Stormfront, the website where Anders Breivik used to hang out online and whose members celebrated the death of Jo Cox.
