I have one niche site old 11 month, i was building backlinks every day by hand, comments, forum profiles, articles. Lastly i have used Article Marketing robot every day submitting articles and pinged the live links only for one time about 600 live links. I have 12 unique and original articles and my website was on first-second page of google. This morning every keyword disappeared from google, only my domain is show on the results. What happened? Google dance, sandboxed? what i can do to go out?
