Just last year, Google had multiple updates for its features, especially with its algorithm continually receiving updates. Many businesses vanished due to updates on Panda, Penguin, and other algorithms. SERPs also saw several different updates, with some ups and downs throughout the year. Updates that were considered as the most popular ones were Google Possum, Penguin 4.0, Mobile Friendly Update 2, and AdWords Shakeup.
