UPDATED May 9: Google News has removed a prominent news source which had faced questions over possible 'gaming' of Google's news gathering algorithm.
"To ensure a high quality service for our end users, we periodically review our index of news sources, particularly following user complaints, and have recently removed some sources that do not meet our criteria as news organizations, including Playfuls.com," a Google spokesperson told Texyt today.
Google News is generated by software which scours more than 4000 sources worldwide and displays the stories that it determines most newsworthy. A number of sources appear to have been dropped on or around April 26, they include Playfuls.com, a popular news website.
Until recently, links to Playfuls' news articles had been extremely prominent on Google News. The site ranked 16th amongst Google News' English-language sources, placing higher than many better-known news organizations according to Newsknife. However, on April 26, new links to Playfuls abruptly stopped appearing at Google News.
