Welcome to the Q&A Forum

Hey there, Sam from Moz's Help  Team here! So, a couple of things - all links do factor into your DA profile. When you disavow a link through Google, it doesn't actually remove the link, Google just stops putting SEO weight into it. So our crawler will still find the link. Unfortunately there isn't a way in Link Explorer to "disavow" a link yet so we will still show it. Disavowing a link doesn't take it away from our tools, so they will still appear as backlinks to your site. The fact that Google disregards them in relation to your site does not take them off the sites they are on, so best practice is to approach the webmaster first and request the link be removed. If you get no response then disavow with Google:). I also want to note here that your Spam Score in Moz Pro is actually the percentage of sites with similar features we've found to be penalized or banned by Google (it's not based on the spam score of the sites linking to you). To improve this score I would recommend reading our guide which explains the 27 factors used to make up this score. You can then look at your site and investigate areas you would like to improve on your site: https://moz.com/help/link-explorer/link-building/spam-score Best of luck, and let me know if I can help with anything else!

Yep, some similar to previous answer advice: lost opportunity for keywords internal linking not the best link profile. At a very basic you could look for good quality web directories and also try to check practices of your competitors (have you gather information who your competitors are?). Maybe there is an opportunity to get link from sites that links to your competitors. try to create good quality content with statistics and references to external, relevant websites (we would advice setting that as nofollow) what's your website mobile friendliness and speed - these two can significantly harm your website
