Hmm.
Sorry for not getting back earlier on this.
Looking at our system-wide CTR, it was actually higher on Saturday, and moreso on Sunday than it has been since the beginning of October. However, looking at traffic for the UK, there was certainly a big dip in traffic compared to other countries, say Germany. I can't think of any particular reason other than the fantastic weather... FA cup? Not sure, maybe people were just outdoors more. However, the number of clicks on UK traffic on Saturday was almost exactly the same as those on Saturday last week... I'll ask tech if they notice anything fishy, but I'm 99% sure it's not something too scary. Hopefully.
Have a good week everyone.
