There is a lot of speculation about whether or not having bad backlinks can hurt your Google performance. Some people say that if you have low-quality links, it will drag down your website’s ranking. Others believe that Google takes other factors into account, such as the overall quality of your website and the number of high-quality links you have, when determining how well you rank in search results.
The truth is, no one really knows for sure what role bad backlinks play in a site’s ranking. However, there are some things you can do to protect yourself from any potential negative effects:
1) Use a tool like MozBar to check the quality of your backlinks and get rid of any that are spammy or low-quality.
2) Monitor your link profile regularly and disavow any links that could be hurting your ranking.
