FAQ
What counts as a toxic backlink here?
We list referring domains that Ahrefs marks as spam (is_spam = true), one example link per domain, so you can review and disavow carefully.
Is this tool free?
Yes. Each IP gets one new scan per day. Results for a domain are cached for 72 hours, so repeat views of the same domain do not burn another daily credit.
Does a spam flag mean I must disavow?
Not always. Review each domain, check the linking page, and only disavow links you believe are harmful or manipulative. The export is a starting point, not automatic advice.
