Welcome to the Q&A Forum

Greeting Hamid As John Cross and Sander Van Dijcke explained you clearly what you lack and basically provided you with articles to refer, I would like to mention few more points which I think you can follow: As you are having low domain authority i.e. Domain trust Focus on Content and convert it into keyword rich (Note: Maintain Keyword Constancy and Don’t Stuff Keywords). As you are having low domain authority i.e. Domain trust check for any errors or broken links in your Webmaster crawl errors database. Focus on Social Share and Building links with high page authority. There are ready available tools, which you can find out whether your website is penalized or not (http://pixelgroove.com/) Check this out. And use MOZ Open Site Explore and try to disavow spam backlinks. Check for website Speed and other small issues using free tools available online (http://gtmetrix.com/ ). Hope this helps Thank You

Howdy! It looks to me as though this may just be a hiccup within the MozBar plug-in; notice that the bar for DmT is partially filled, but there is no value displayed. So, I'd recommend clearing your cache and cookies, and potentially checking the value in MozBar for Chrome. Checking the value in Open Site Explorer's 'Compare Link Metric' section would also be a good way to see if the value does indeed exist :). If none of those seem to resolve the issue that you're seeing, then I would recommend writing in to us at help@moz.com with some more specific examples.
