Hi FS Makers an reviewers.
I have more than 6 months submitting FS to 60 LL aprox with this domain: thetgirls.com
I made some hubs, link trades, etc...but I still have not Search engines enough traffic.

1-I think it could be because for posting to 60 LL, y make 4 different index. (Duplicate content).
Do you think its to bad for Google?

2-What should i do or stop doing to my FS have SE traffic?

Thanks people.
