One of the most important SEO tools for removing spam links is the Disavow tool. Disavow is actually a file containing a list of links that you send to Google. This file tells Google to ignore all the links in it so that they have no effect on your site. This will prevent you from being penalized by the Penguin algorithm and negative links will not decrease the site's rank.
Note that even if you mistakenly put a quality link in the Norfolk Island Email List disavow file, that link will be ignored and will not affect your ranking! So be sure to put the links in the disavow file carefully. After sending the disavow file, Google will send you a confirmation and after confirmation, it will process the file. But it doesn't mean that it will increase your site's rank quickly.
If you have already sent a disavow file to Google and you plan to send a new file again, Google will replace the previous file. Therefore, be sure to include the previous links in the new file.
Once you have removed the malicious and spam backlinks, don't make any effort to get new and valid links.
Don't remove all negative backlinks. So check your links again and add the remaining spam links to the disavow file.
Many people think that once the penalty is removed by the Penguin algorithm, their ranking will improve quickly. While this is not the case.
