I've been having trouble ranking my site for my targeted keywords and I see everywhere that people say that bad links can hurt you, and some would say to disavow bad badlinks. I have also read some people say that any link is good and never to disavow them. I do not have any Google manual actions, and don't have any indicators for spam. my site is not deindexed. I'm just curious to whether or not having certain links can actually do harm to you in that sense, whereas Google won't even tell you, but you'll just find it very hard to rank for your keywords? Any suggestions?
