Thousands of websites, blogs, and niche review sites have old affiliate links that lead to expired offers, shut-down stores, or 404 pages. These links still receive traffic and SEO juice, creating daily wasted opportunity. This tool monitors indexed pages for high-authority websites and blogs, crawls outbound affiliate links, and identifies which ones now return 404 or 410 errors. It then notifies the site owner (offering a fix via outreach SaaS or upsell), or provides you with the option to instantly redirect that link (via expired domain acquisition, cloaked redirect, or replacement offer). One-time setup. Multiple monetization paths. Works as a SaaS, affiliate sniping engine, or link rescue service for agencies.
