How Google Panda Was Developed
• Google Engineer came up with questions.• Sent questions to human quality testers who rated sites
– Rated based on quality, design, trustworthiness, speed, and whether or not they would return to site
– Google came up with definition of “low quality”• Launched Personal Chrome Site Blocker extension earlier.
– Allowed users to specify sites they want blocked from search results
• Compared data from both sources (Raters and Chrome Blocker), and had 84 percent overlap, indicating on right track
• Came up with Classifier to indicate Low Quality vs. High Quality Sites, to be used mathematically in Google Panda.
