After weeks of complaints, Google has tweaked its search algorithm that had led users to a Holocaust denial website maintained by racist neonazis.

"We recently made improvements to our algorithm that will help surface more high quality, credible content on the web," read a statement from a Google spokesperson.  "We'll continue to change our algorithms over time in order to tackle these challenges."

Several news outlets had reported that the query "did the Holocaust happen" directed users to an article from an American white supremacy group that claimed it never took place.  Beneath that were sites for Jewish museums and ones that show the Holocaust was real.

In order to have results placed above the racist site, legitimate museums had to pay an extra fee of up to US$2 per click.  The Breman Museum, a Jewish heritage museum in Atlanta, was relying on an advertising grant from Google to pay that extra cost.

This is not the first time that Google had to alter its technology to thwart anti-Semites.  Last year, the search engine removed a search result that gave an anti-Semitic answer after asking the search engine "Who Runs Hollywood".  The search engine also altered its auto-completion suggestions earlier this month after racist, anti-Semitic and misogynistic prompts like “are Muslims bad” and “are women evil” were reported.  Even worse results came from other searches.  Google at the time said its algorithm would lead users to a site that had been linked to over and over again.

Heidi Beirich of the US anti-racism organization the South Poverty Law Center says Google still has much work to do.  "Facebook is getting slaughtered on the fake news front, but in many ways, this Google problem is more insidious," she said.  "People might assume that what they're getting is vetted, and that certainly is not the case."
