So our Google Analytics are showing us that 200% increase of "organic" search traffic. Analytics are saying that search keyword is "(not provided)". We are wondering how to find out which keyword is causing this?
We are monitoring all important keywords for our website. None of keyword is in first 5, so our "organic" serach traffic is modest. However, today we received 200% increase of "organic" search traffic but none of keywords we can think of moved a bit. We also did not change anything related to SEO.
And what is interesting Google Webmaster shows no changes - ~2500 impressions and ~200 clicks.
How to find out which "keyword" might be causing this spike?
