President Donald Trump has accused Google of manipulating the results of the search by the phrase “the Triumph of news”.
In a tweet, accused the technology giant of the prioritization of negative news stories based on what he described as the “national left-wing media”.
He said that most of the stories that appeared on the page of results were negative and that the conservatives reporting “suppressed”.
The BBC has been in contact with Google to make comments.
Mercedes Bunz, a professor of digital technology at Kings College London, told the BBC that it was highly unlikely that Google was deliberately ranking of the information according to political bias.
“Google’s news algorithm is optimized by the current, and the proximity of an event, but in general is not optimized to search for political orientation,” he said.
“However, it has a tendency to classify the web pages more than a lot of people in the link.
“For the news, this seems not to have changed with Google’s latest update of its search algorithm, which was launched on 1 August.”
Google says in its support page that there are “over 200 factors that feed into the ranking of a website in their search engine.
In his tweets, President, Trump stated that 96% of the news articles presented by Google in response to the phrase “Triumph news” were left-wing news media.

He did not name the source of this figure, but The Edge web site reports that seems to come from analysis by Paula Bolyard on the conservative news site PJ Media.
Ms Bolyard reported that the 96% figure, and said CNN had the largest number of featured links, that the President of Triumph mentioned.
“I’ve done a search several times using different computers are registered to different users, and Google returns similar results,” she wrote.
“While not scientific, the results suggest a pattern of bias against right-wing and in content.”
