Today on Webcology we start off with a Google Search Algorithm Ranking Update. We had a Google algorithm update over the weekend, starting probably late Friday, October 6th and rolling out over the weekend. Most took notice on Saturday, October 7th but the chatter is still fairly strong and will likely remain strong for a net couple of days. It turns out Google Mobile Ranking updated. A lot of folks are not just continuing with their chatter on the Google Columbus update but also now we are seeing specific ranking changes in Google mobile results. It is hard to tell if the chatter is specific to mobile or desktop or both. But when you look at the tracking tools, a lot of them are showing huge swings specific to the mobile Google search results. Also, Google Suggests They Use Off-Site Sentiment Analysis For Ranking as well. Gary Illyes from Google was quoted by several SEOs as saying at the State of Search event that Google uses a form of sentiment analysis for search rankings. He said that Google looks at off-site sentiment to find supporting signals about the quality of a site. He also said that can mean both positive and negative off-site sentiment. The quotes suggest that this may be taken from social signals as well as other website mentions. This is not just about links, Gary Illyes said.
