I have an e-commerce site that is just now beginning to rank in the top 2 for very competitive keywords and starting to bring in meaningful traffic. As such, I'd like to strike a solid balance between further serp improvement on other keywords and safety, i.e. protecting the traffic that I have right now. Below is a quick summary of what I'm doing: 1) e-commerce site -- plenty of relevant content; no keyword stuffing 2) automatic link building only with content -- I rely mainly on well spun, relevant articles, blog entries and social bookmarks for my links 3) scrapebox to help links get indexed -- right now, I use scrapebox runs to link to my first tier backlinks Of the above strategies, I'm most concerned with the scrapebox blasts. Although I'm not using scrapebox to link directly to my money site, I'm not sure if one layer of separation is enough. Questions: 1) I'd like to hear if anyone in this community has had experience with sites that have been penalized by Google, what might have caused the penalty, and how the penalty was removed (if in fact it was removed). 2) Also, if anyone has experienced any penalties using the strategy that I am currently using, please do share. 3) Would it be safer to use web 2.0 profile or forum profile links in lieu of or in front of the scrapebox blasts?
