Does Google penalize sites with submissions to lesser directory sites that are "free" or potential seen as spam by Google? I want to submit my blog but I'm worried that Google will label submissions to free link building sites as exactally that... I have no problem going with quality niche directory sites however, I'm wondering; do submissions ever place you in the Google sandbox? Do linkbuilding campaigns backfire in this way? I really appreciate your real world experiences and insight on this important SEO issue... Thanks!
