How do we deal with huge and sudden changes in organic search traffic now that Google no longer posts major updates to its algorithms? Since many updates that formerly would have been assigned a name (like Penguin or Panda), or even a name and an incremental number (Panda 3.0) are now part of Google’s core algorithm, how can we know when an update is responsible for a traffic or ranking change? And even if we do know, what can we do with that knowledge?
