Deltio

Deltio watches your sites 24/7 so you never discover an SEO problem from an angry client. Add a domain and it auto-discovers sitemaps, tracks URL additions and removals, and scans titles, descriptions, H1s, canonicals, and hreflang tags. It also monitors HTTP status, response times, SSL and domain expiries, cookie code, and robots.txt changes. The moment something breaks, you get an alert via email or Slack with full history and reports so you catch issues before they cost you traffic, rankings, and client trust.
