I have a site that's been consistently ranking for multiple generic keywords on Page 1. For the past two months, I've noticed on ahrefs that I'm getting low quality backlinks almost on a daily basis. I checked the domains and they all seem to point to a single individual/company. I really think I'm being attacked. Consequently, my rankings have gone down. I regularly disavow these domains on Google but the backlinks keep coming.
Any other remedy to counter negative SEO? Are do I really have to track this guy/company and warn them of legal action? Thanks.
