One of the first challenges link builders discover starting in a new industry is that building relationships takes time. Promoting infographics, guest posts, and other linkable assets with cold contacts can be difficult.
So a major focus in link building is relationship building. A few methods we've covered in the past include networking, e-mailing friendly commentary, blog commenting, blogging, using trackbacks, and connecting via Twitter and Linkedin.
In all these cases, the basic strategy is the same: contribute to the conversation in your industry, build relationships with influencers, and hope that those relationships lead to links.
