Ok, thank you! So if consider such approach as you have I didn't refresh disavow file.
but I regularly add to it links like from porn or content scrappers or search engine or services. From the last month I noticed the coupon codes low quality websites that just steal my content with dofollow...
Thank you for all details! I see all business owners here do not refresh disavow file, but it need to be refreshed. I just wondered, so if I ad guest posts done I should disavow them? Didn't understand this part of your message Which links should be disavowed among all guests?
