niche edits have been shown to work before but i would not say whether or not the link will work based on the type of link. sometimes, it can actually be good to have a relevant link on a piece of old content if that particullar page receives traffic already. as long as u avoid websites that promote any type of edit randomly on their website, everything should be fine.i keep hearing mixed opinions about adding links to existing articles. have niche edits worked well for anyone recently, or are guest posts a safer option?
