Why Now?

Google's 2025 core updates penalize sites with poor link health more than ever. Content sites are growing larger, making manual checks impossible. SEO agencies need scalable, automated solutions.

Revenue Model

SaaS: $12/mo Solo (1 site, monthly crawl), $29/mo Pro (5 sites, weekly crawls), $79/mo Agency (25 sites, daily crawls, white-label reports).

Competitive Landscape

Screaming Frog

Desktop crawler. Powerful but requires download, technical skills, and manual scheduling. £199/yr

Ahrefs

Has broken link reports but it's a $99/mo full SEO suite — overkill for just link checking

Dr. Link Check

Simple cloud checker but slow, limited free tier, and basic reporting
