My site has been steadily going downhill the last several years despite steady improvements to the quality of the site before and after the drop started. I assume a lot of this is due to panda/penguin issues.
However, the initial and perhaps largest drop seemed to coincide immediately after I *started* using Google Analytics. Is it possible that once Google obtained increased visibility to my site that is what caused them to knock me down? For example Google may not have known my bouce rate before I enrolled in GA, but they do now.
