Google declares war on content farms- Google announced a significant algorithmic change this week that will directly target content farms and ultimately improve the quality of Google’s search results. According to a blog post  published by Google’s Amit Singhal and Matt Cutts, “This update is designed to reduce rankings for low-quality sites — sites which are low-value add for users, copy content from other websites or sites that are just not very useful. At the same time, it will provide better rankings for high-quality sites — sites with original content and information such as research, in-depth reports, thoughtful analysis and so on.” Google introduces a new ad rotation setting in AdWords- Google announced on Wednesday a new setting in their AdWords’ ad rotation, which will enable advertisers to better optimize for conversions. Prior to the change, marketers had two options, either to optimize for clicks or show ads evenly. With this change, marketers can now elect to show ads with better conversion rates more often. To learn more about the change, check out Google’s Inside AdWords’  blog post on the topic. Bing and Facebook cozy up in social search- Bing and Facebook announced  this week that Facebook’s “Liked Results” will soon be integrated into Bing’s SERP. This should come as no surprise after Google’s update to social search , which did not include Facebook “Likes”. According to a blog post from Bing, “While we are very excited to talk about our next development, we're all aware that it's all part of a longer journey. This is the first time in human history that people are leaving social traces that machines can read and learn from, and present enhanced online experiences based on those traces. As people spend more time online and integrate their offline and online worlds, they will want their friends' social activity and their social data to help them in making better decisions. Integrating with Twitter data 16 months ago was one step, and exploring Facebook's rich streams is another."
