I am just stumped right now and would love to hear from the experts here. We run two sites. One of our sites seemed to have been penalized by the big G - since we do a lot of backlinking for that site. On the other hand, we have another site - we have not done any backlinks - and major keywords are number 1, 2 or 3. Both sites are updated with 100% unique articles. Which leaves us wondering why if we should do any backlinks at all? What do you guys think?
