Expose Hidden PBNs & Link Networks Before Google Penalizes You
Detect link networks, PBNs, and spam clusters with SEOScaleUp's free Link Network Detector. Uncover hidden backlink patterns, identify toxic link neighborhoods, and protect your site from Google penalties—no signup required.
Stop Hidden PBNs & Link Farms From Destroying Your SEO
Link network detection identifies interconnected groups of websites that link to each other—often Private Blog Networks (PBNs), link farms, and spam clusters designed to manipulate rankings. These networks are prime targets for Google penalties.
SEO professionals unknowingly acquire links from toxic networks that trigger algorithmic penalties. Our Link Network Detector analyzes backlink patterns, IP addresses, WHOIS data, and content similarity to expose dangerous link neighborhoods—before Google takes action.
PBN Detection Algorithm
Identifies Private Blog Networks using 30+ signals: IP overlap, WHOIS similarity, content patterns, linking structure, and domain age consistency. Flags networks before they impact your rankings.
IP & Hosting Overlap Analysis
Detects domains sharing IP addresses, C-class blocks, and hosting providers—classic PBN fingerprints. Visualize clusters of sites on the same infrastructure.
WHOIS & Registration Correlation
Cross-references domain registrant data, creation dates, and registrar usage. Identifies networks where multiple domains share the same owner details.
Content Similarity Detection
Analyzes site content, templates, and writing style to identify networks using duplicate or spun content—a hallmark of low-quality link schemes.
Network Visualization Map
Interactive force-directed graph showing how referring domains connect. See clusters, shared IPs, and network size at a glance.
