Domain Migration Health Monitor & Alert System
A SaaS tool that continuously monitors domain migrations by tracking redirect status, canonical selection, sitemap integrity, and GSC indexing data. It alerts website owners when Google starts reverting canonicals or when any signal chain breaks, enabling early intervention before traffic loss occurs.
Pourquoi c'est important
You run a successful website and decide to rebrand with a new domain. You follow every best practice for domain migration and traffic recovers nicely. Then four months later, Google inexplicably reverts everything back to your old domain. Thousands of pages drop to crawled-not-indexed status, daily impressions crash from 5,000 to 20, and brand-new pages that never existed on the old domain simply refuse to get indexed. The only diagnostic path available is manually inspecting URLs one by one in Google Search Console, checking redirect types, comparing canonical signals, and hunting for what changed on your hosting or CDN around the time things broke. There is no tool that monitors your migration health continuously or alerts you the moment Google starts losing trust in your new domain.
- · Conçu pour SEO professionals, website owners, and digital marketing agencies managing domain migrations or redirects for sites with significant organic traffic.
- · Monétisation la plus probable : SaaS subscription.

Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1Google Search Console API rate limits and data delays of 2-3 days could make alerts arrive too late to prevent traffic loss, undermining the core value proposition of early detection.
- 2Domain migrations are episodic events — users may subscribe during a migration and cancel once the crisis passes, making it hard to sustain a recurring revenue model without expanding into broader SEO monitoring.
- 3Google could at any time improve Search Console with built-in migration monitoring and canonical change alerts, instantly commoditizing the tool's primary differentiation.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
Approximately 5 commenters in the discussion describe the painful, manual, and disconnected diagnostic process for domain migration failures. Users report manually checking redirect types, comparing Google-selected vs user-declared canonicals one URL at a time, cross-referencing sitemap status across old and new properties, and trying to correlate hosting or CDN changes with indexing events. The original poster reports catastrophic traffic loss from 5,000 to 20 daily impressions after Google reverted their migration. Multiple commenters recommend checking the same set of disconnected signals, confirming there is no unified diagnostic tool available.
