It depends. The Google update that just came out, as it did last year, will usually be geared towards e-commerce websites since this is their month to shine. You might see some fluctuations, but you shouldn’t be seeing anything too major. I’m not dealing with the situation and not expecting to.
Have you done a backlink audit? Maybe you got an influx from somewhere and it gave you a quick boost and Google just needs some time to even back out. Have you made any other big changes recently?
