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.
Step-by-Step Guide to Success
Build a crawler to index outbound links from niche blogs and affiliate-heavy sites.
Scan for HTTP 404, 410, or timeout errors across all outbound links.
Tag links that contain affiliate patterns (e.g. '?ref=', '/go/', 'affiliate_id=').
Create alert system to contact site owners offering fixes, alternatives, or redirection services.
Offer SaaS plans to webmasters for continuous monitoring.
Optionally acquire expired domains of broken links to redirect traffic to similar affiliate offers.
Create database of recurring broken offers and replace them with evergreen alternatives (via API).
Monetize via SaaS subscriptions, CPA redirects, expired domain traffic, or outreach services.
