And by content, I'm not referring purely to the anchor text. Traditionally, content oriented links would have been articles, videos, podcasts and press releases. While these still apply, you can also add to that list blog comments, guest blogging and forum commenting IF they are relevant to your niche and contain significant content.
Less likely to have an impact is simply getting a link on a directory or in a profile. However, social bookmarking sits somewhere between these two areas as sometimes social bookmarks appear as just a link with maybe a short comment whereas other times, they carry a more detailed description or review of your website. Then of course, there is the issue of website authority and page rank. Links from authority sites and high page rank web pages are likely to carry more weight.
