Hello friends,

  I want to know that How are bad links characterized?

It's On A Low-Authority Or Questionable Domain
It's Pointing To A Source Irrelevant To Its Content
It's Repeated Too Many Times On The Domain
It's A Part Of A Reciprocal Exchange

Links from sites that are unrelated to your sites
Low authority domain
Links from low Page Rank and Low traffic

Bad links means not relevant link to our sites.

1. It's Embedded In Suspiciously Keyword-Matched Anchor Text
2. It's Isolated From Any Meaningful Content
3.It's A Part Of A Scheme
