Was there another update?
Our website traffic drops at night times (11pm - 4am) on under 5% in last 14 days. No changes where done on website from our end.
AccuRanker, RankRanger and SEMrush Sensor are showing high level of SERPs fluctuations on July 9, 2017 . Maybe the start of a new algorithm update, who knows happy!
I'll keep an eye on the SEO community chatter but I strongly doubt we will get Google to confirm any update here.
