About

Link Sonar is AI-powered link building software built for SEO agencies, in-house SEO teams, and freelance link builders who need to scale outreach without scaling headcount. The platform consolidates the entire link building workflow into a single dashboard: boolean search-powered prospect discovery, automated contact enrichment, AI-generated personalized outreach emails, multi-step follow-up sequences, real-time backlink monitoring with instant alerts, A/B testing for subject lines and copy, and white-label client reporting. Link Sonar replaces the patchwork of spreadsheets and disconnected tools that slow most link building campaigns down. It is a modern alternative to legacy platforms like Pitchbox and BuzzStream, delivering agency-grade capabilities starting at $49/month. Start a free 14-day trial today.
