Reference links that direct users from one website to another are called backlinks. Reference links obtained from reliable and authoritative websites help the respective website to appear more reliable and authoritative in the eyes of Google. This, in turn, contributes to the performance of the respective website on the search engine results pages. However, having a large number of non-organic and bad backlinks will harm websites. Therefore webmasters should be very careful when it comes to backlinks. Also, backlinks on a website should be checked regularly by performing malicious link analyzes. These analyzes can be carried out using several free or paid tools. After these analyzes, bad and spam backlinks should be removed using the Disavow tool in Search Console.
