2. Penguin Unleashed
Paid link exchanges have been a big part of gaming affiliate SEO strategies for a long time, but in February, Google Penguin changed that plan for good. Overnight, Penguin made link quality a top issue for gaming affiliates and paid link exchanges were a thing of the past. Penguin’s ability to tank page rankings caused major headaches for webmasters who were forced to evaluate and/or remove practically every link in their ecosystem. By the end of the year, most SEO gurus agreed that building up an inventory of quality links was a better option than trying to remove the old ones. No matter which route you took, Penguin was a very disruptive force in 2012.
