Hi all, I have a site for which I am doing linkbuilding for 10 keywords. Half of them had a top 5 position in google.nl and the rest was coming along nicely (positions ranging between 15-30). One keyword however was stuck at position 150. Yesterday I built 5 profile links on high PR sites and then pinged them. When I checked about 8 hours later I could see that this keyword had jumped to page 1. Next day however ALL 10 keywords had disappeared from the rankings. Also when I checked whether my pages were still in the index with site:mysite google only returns pages that are in the cache from 20 December. What happened? Did I trigger a penalty?
