Does anyone have a clue about an annual algorithm update that happens between March 8-9 to March 14-15? Or maybe there's some type of technical audit of specific technicalities, I'm not sure how to put it. One of my websites is undergoing a similar traffic loss to last year, starting and finishing exactly within the same dates. Last year we accounted the traffic drop due to loss of a type of rich results, which were never re-enabled, but this year everything's in the blue. I saw Barry's article about a possible Google update. I'm curious if anyone experienced similar changes within this time frame.
