By 2004, search engines had incorporated a wide range of undisclosed factors in their ranking algorithms to reduce the impact of link manipulation. In June 2007, The New York Times' Saul Hansell stated Google ranks sites using more than 200 different signals. The leading search engines, Google, Bing, and Yahoo, do not disclose the algorithms they use to rank pages. Some SEO practitioners have studied different approaches to search engine optimization, and have shared their personal opinions. Patents related to search engines can provide information to better understand search engines. In 2005, Google began personalizing search results for each user. Depending on their history of previous searches, Google crafted results for logged in users.
Hi Brian, Awsome content as ever! I’m very interested in your idea of creating an ‘uber’ resource list or expert roundup post i.e. linking out to lots of to other authorities in my niche within one post. But should you always create ‘no-follow’ links to these authority sites to prevent juice from passing to them? And similarly if you sprinkle a few outbound authority links in other posts should they all be ‘no-follow’ or do you think big G ignores ‘no follow’ these days?
