Last few months I have started seeing strange build up of strange backlinks that are building hundreds of backlinks per day just to delete hundreds the next day.
Some of these backlinks are porn related, some are completely unrelated to the content and product we sell. My question is, could this be some negative SEO attacks?
Are other people dealing with similar issues regarding their backlinks? Are you sometimes finding porn or unrelated sites linking to you?
Should we run a backlink audit every few months to remove bad backlinks? What are your best practices when it comes to dealing with bad backlinks?
