I have a website i have been rankin for the last 2 months . Before 2 days ago i was tracking 5 kws and one of them was ranking on first page. Yesterday all of my kws hit first page . When i woke up this morning all kws i was tracking went down to position 100-250 I have had kws drop and then few dayas later they would bounce back stronger but always just one kw at the time not all of them like now . So whad do you think ? Is it the normal google dance or is this somethig else ? I have no messages in webmaster tools regarding any penalty..
