My SERPs behavior 2007 : 8th of January, huge traffic came, 10k key phrases in top 10 positions. --18th Jan the G switch goes "off" --27th "on" --28th Jan "off" again, i mean all the key phrases jump to 8th or 10th pages! --the 30th "on" as nothing happened --3rd February "off" in 4 hours "on" again --Steady "on" for almost 3 months --19th of April "off" i mean all my google rankings went to hell ))) --In a few hours "back on" --26th of April "off" --28th "on" --2nd of May "off" --5th of May "on" --12th of May "off" -- Till today i live in a Google desert, hello.. anybody there? Well interesting to add that image ranking positions have always been stable, google still brings me about 100 daily from images. So my SERPs have been gone for 13 days now.
