I had a site on 15th spot. I built lots of junk links to my site. It got sandbox or something. After 3 months it came back on 8th position. I decided to buy quality links (1500 word unique articles on high pr blogs with only one link inside). My site came to 2nd spot in a week. I continued to buy blog reviews. It came to 1th spot and on the same hour, all my keywords disappear (not in 1000, or 60th-80th-500th,etc.) I think this is a google dance (which i'm not sure yet). But even it is a google dance, listening the recommendation of continue to buying links is a good idea? Won't it increase the time of its turn-back. (i don't want higher positions, just want my last spots-2th or 3th) Won't continue to buying links will cause an endless spiral? (it will dedect new links, re-decide my position, and will see newer links, re-decide my psition, so on so on... Although 90% of members advice continue to building links, it doesn't look logical to me (but i'm still doing what majority tell) Any opinions?
