Google Fred is an algorithm update that targets black-hat tactics tied to aggressive monetization. This includes an overload on ads, low-value content, and little added user benefits. This does not mean all sites hit by the Google Fred update are dummy sites created for ad revenue, but (as Barry Schwartz noted in his observations of Google Fred) the majority of websites affected were content sites that have a large amount of ads and seem to have been created for the purpose of generating revenue over solving a user’s problem.

Many of the automated tracking tools currently show significant volatility and fluctuations, which is an indicator of an update. Plus, with all the industry chatter, and with webmasters both complaining about ranking declines and rejoicing about ranking increases, it’s likely that there was a Google update.
