Hello, a couple of years ago I started publishing on my site more than 10 posts a day of content that no one else had. For this reason, my competitors started paraphrasing my content without giving proper attribution, and they ranked better in Google. That's why I realized that apart from creating content I had to work on my SEO, so I started to get some backlinks, most of them via contests on blogs. I am getting about 1 high quality link from PR2, PR3 or PR4 blogs each week. According to Open Site Explorer, I have 20 root domain links (200 total links). In reality I have more backlinks but they don't show up (they do show up in Ahrefs, about 50 root domains). To my surprise, I only have 15 Domain Authority. This is the most evident example, take a look at this screenshot: http://imgur.com/dFk2rkx My website is on the far left, two of my competitors on the right. As you can see I win every category except total links and the most important, domain authority. Are total links that important for Domain authority, even if 99% are internal? By the way, I also have more posts than these guys, I don't know why the report says otherwise. Why is the site on the right ranking so high? The same thing happens with the rest of my competitors, they have a lot of low quality links from "lists of domain sites" and in general a lot of very spammy links. According to what I have been reading, my good quality links should be more helpful than my competitors'  spammy links, which should in fact affect them. So what is going on? I have no idea if I'm doing things right. Why is my domain authority so low? Thanks for your help. dFk2rkx
