Does anyone know at what point is best to email google that you notice something abnormal in click thru rates? for example if your click thru rates are usually around 5%, then should you email them when they hit 10%, 15%, 20%, 25%, or 30% , or all, or neither? How often do you guys email them? Its just that I dont want to shout the words 'fire' in a crowded movie theater if you know what I mean. But on the other hand I do want to be diligent and notify them of unusuall activity.
whenever you feel it is a abit dodgy, theres really no set rate, you must remeber also that you get some days with alot more than others, nothing will ever be consistant in the world of making money on the web
