Hi, lets say I target 3 KWs (blue widgets, red widgets, green widgets). All of them for the same page: www.xxx.com/yyy. 2 days ago one (!) of my KWs dropped from #1to #82. The other KWs are still in top 3. Is this a Google dance or have I been penalised for one keyword? Is it possible to be penalised for 1 KW in this situation? Thanks for help!
