Welcome to the Q&A Forum

I was just expecting some "peak" in analytics, but there was none.

Is there any other possibility, other then personalization?

Already did, its not personalization. We really are no 2.

But is there possibility that personalized SERP of our potential visitors is the problem? That we have lower rankings on theirs SERPs.

Tnx

Yes, its 20k pr month. And its base KW for our industry.  Tnx

We were ranked no8, and in one week we jumped to no2 on Google, but there is no change in nuber of our visitors. What is going on? Is it personalization of SERP? What can we do? Tnx
