Hi, How comes that when I do lot's of internal link building and also build external links for 3 different keywords that they suddenly show up on spot 7,12 and 9 just for a few hours and then they jump back to spot 70,150,52.. I thought it was a Google Dancing, but it has been 3 days since the first keword did it and it moves nowhere atm. the second keyword did it for 11 days and still not moving the 3 keyword did it today. Is there any reason for why it is so, maybe penalty or something from Google? I use SERP BOOK, SEMRUSH and Some other tools to check ranking.
