"This is bound to happen at some point as it has happened before in the past. Obviously, SEO is very important because any change to it and we might lose traffic to our website or blogs because they are no longer ranking high in the search engine results. First, I would strive to be proactive, staying up on breaking news about these kinds of changes so we aren't caught off-guard. If a change did take place, I would research it; every time this happens experts post recommendations on how to combat or fix the problem. I would also make sure that our SEO checklist is continually monitored and up-to-date because if everything else is already optimized one change likely won't ruin our rankings completely, and we'll be able to quickly recover."
