Organic keyword ranking drops across the board?

[AscentGroup]

Howdy Moz,

I have noticed a common anomaly across the majority of my client accounts (see attached image).

Have lost thousands of organic keywords worldwide? (no loss in UK rankings though which are the ones that matter)

Has there been an algo update?

Seems strange.

Thanks,

Joshua

This might not be affecting you or your clients, but there is a Google bug which is sinking results in SERPs if the page has an embedded video. Details here.

Is this the behaviour that you're seeing?

There seems to have been significant movement in the SERPs around November 10th in the US (which could have hit the UK a couple of days later, although I have no data to support that). Unfortunately, we don't have much in the way of details or confirmation right now.

Are you seeing any specific pattern in the loss? I'm not quite sure I understand what the graphic is showing.
