Welcome to the Q&A Forum

Hey guys, over the past two months my DA has gone down from 17 to 12, and I have no dura what could have caused it. I started putting in some Amazon affiliate links in my posts - could that be the reason why? Also, I have about 30 backlinks from a blog with a spam score of 11% - could this also be affecting it in any way?

I have been doing everything right that I could possibly do on my blog, tracking down and deleting broken links, writing for endless other publications to build my link profile, having an easy to read site with regularly updated content. Despite this, my DA has gone down by two. It's infuriating and I don't know why this is happening - does anyone have any ideas?
