I have always been sceptic about using analytics on my sites because I don't want google to know my real bounce rate and such. So I have this little e-commerce site that has been ranking pretty decent for the last 5 months. Now I wanted to get a little bit more info that some of the analytics alternatives are not giving me so I was like what the hell, I'll just add google analytics. 5 days later this happend: Keyword 1: 4 > 13 Keyword 2: 3 > 7 Keyword 3: 1> 10 Keyword 4: 1> 3 Pretty much all the keywords I was ranking for pretty stable for 5 months dropped 3-15 spots 5 days after addding Google analytics. Amount of organic searches I'm getting now: I don't this is a penalty or a penguin 2.0 slap or anything. It's just that google now knows the real bounce rate of the site ( ~65% ) and was like that is to high, time to adjust your rankings. Hope this is a lesson for some of you and don't make the same mistake I made.
