Does Blue arrow on Google SERPS decrease your visits?

I recently saw at Analytics ( Traffic Sources > Search Engines > Google > )that my firsts positioned SERP keywords in Spanish Google: “musaka”, “leche frita”, “recetas con carne picada” have decreased incoming visits from Google from -17 to -25% just because they are marked with the blue arrow.

I check those words the 29th of september versus 30th september (the day the blue arrow was launched). It is incredible how the visits from Google are decreasing just because the little arrow.

I suppose most of users see that little arrow as an “Advertisement” and thats whay they dont click as usual in the first position of SERPS.

This is very very annoying for my first ORGANIC and FREE positioned keywords at Google. But think about the ADWORDS blue arrowed SERPS. Yes, Google adds a blue arrow to Adwords too… wow!! So now the 1st positioned pay words must decrease from 15 to 25% too??…. woooooooow!!! Who is the person in charge of this change in the Google SERP Interface?

My webpage has almost 7000 visits per day. Here you can check the decrease of visits from Google from 29th to 30th september:

Im a bit worried about this because I checked the difference between this first positioned keywords the other weeks and they dont use to be so different.

Did anyone check if blue arrow is good or bad for your traffic?

Its very simple, just compare 29th to to 30th September keywords incoming from Google …
