But the wrong kind of backlinks can have a negative impact. This is why it’s important to only have high quality backlinks and to make sure negatively impacting links are disavowed. 

Here is a short list of factors to consider when evaluating the quality of a backlink: 
Trustworthiness – Google puts a lot more weight on trusted, popular websites. Websites that Google recognizes as reputable and trustworthy. Websites from globally recognized sources such as BBC, The Huffington Post, The New York Times, and in some cases even Wikipedia are often considered trustworthy by search engines. Having backlinks from such valuable sources will add great value to your ranking and organic traffic. 

Relevance – Industry relevance and correlation is also important. Its more valuable to have backlinks from websites relevant to your business, and your industry than you have links from random sources. 

Page Authority, Domain Authority or PageRank – this is an algorithm used by Google to rank a website on the search engine result pages. You can easily check any website to determine how valuable your backlink will be.
