  Gerry White: Raising your DA is great for selling more links - other than that, my goto vanity metric is Sistrix visibility Seriously - good content is the best first steps, but in addition, use what you know to write on other peoples sites (I am not talking about guest blog type sites) If you can write good content for a company in your niche, you will be able to get good backlinks, Can you offer resources or other assets that people would want to link to ? Unfortunately getting true links the whitehat way just isn`t always feasable
