Hi Guys, Id like to start by saying that my website ranks on first page (average around 6-7 place) on google for most of its targeting KWs. Many years ago I made the stupid mistake of buying seo packages which included crappy spun articles, forum profile links, blog spam. While back in 2010 this worked things as we know changed and I am still left with a handful of spammy links (roughly 20%). Most of my high quality links come from my own network of sites on separate hosting much like a pbn. my question is, if I remove these 20% bad links or disavow them could they help me increase my SERP positions even though I am already on the 1st page? or in this instance there is no way I have any kind of penalty as google is just ignoring the bad links and only taking into account the good ones I have?
