Google may have released Penguin 3. On October 21, 2014, Google’s Pierre Farr confirmed that Penguin 3. 0 was an algorithm „refresh“, with no new signals added. Penguin and Panda „currently are not updating the data regularly“ and that updates must be pushed out manually. This confirms that the algorithm is not updated continuously which was believed to be the case earlier on in the year. The strategic goal that Panda, Penguin, and the page layout update share is to display higher quality websites at the top of Google’s search results. However, sites that were downranked as the result of these updates have different sets of characteristics.

On September 23, 2016 Google announced that Google Penguin was now part of the core algorithm meaning that it updates in real time. Hence there will not longer be announcements by Google relating to future refreshes. Real-time also means that websites are evaluated in real-time and rankings impacted in real-time. Two days after the Penguin update was released Google prepared a feedback form, designed for two categories of users: those who want to report web spam that still ranks highly after the search algorithm change, and those who think that their site got unfairly hit by the update.
