A few weeks ago, rankings for pages on a key section of my site dropped an average of a full position in one day. I’ve been an SEO for 7 years now, but I still ran around like a chicken with my head cut off, panicked that I wouldn’t be able to figure out my mistake. There are so many things that could’ve gone wrong: Did I or my team unintentionally mess with internal link equity? Did we lose links? Did one of Google’s now-constant algorithm updates screw me over?
