We catch the problem
before your client does.
Deltio checks your sitemaps and SEO metadata every day and watches your server uptime around the clock — and alerts you as soon as something changes.
No credit card required · Setup in 2 minutes · Cancel anytime
The only tool that monitors sitemaps, SEO metadata and server uptime in one dashboard — without three separate subscriptions.
Why it matters
Three scenarios you've lived through.
Or will.
The dev deployed on Friday.
Fourteen product pages silently vanished from the sitemap. Your client saw the traffic drop Monday morning — before you did.
URL removed from sitemap · undetected for 72h Someone edited a template.
80 page titles became "undefined". Google recrawled them over the weekend. You found out when rankings collapsed.
Title tag broken across 80 pages · recrawled by Google The server went down at 3:47 AM.
Four hours of downtime. No notifications. No alerts. You were asleep. The client was not.
Site unreachable · 503 · downtime 4h 13m With Deltio, you'd have been the first to know.

Add a new site
Deltio watches
Every URL added or removed from your sitemap. Every meta tag change. Every server status check. All tracked automatically.
You get the alert
Email or Slack — exactly what changed, on which URL, and when. The alert arrives before your client even opens their browser.

What people say
Trusted by SEOs, web developers, agencies and clients who hate surprises.
"I found out that a client accidentally removed 40 product URLs from the sitemap. Deltio flagged it within a day. The client didn't even know it happened."
Marco R.
SEO Consultant · Freelance
"We manage 15 e-commerce sites. Before Deltio, broken meta tags would stay undetected for weeks. Now I have a Slack message before I've finished my morning coffee."
Sophie L.
Head of SEO · Digital Agency
"The sitemap monitoring alone is worth it. It's like having a junior SEO checking every site, every day, without forgetting. Pays for itself with one incident caught."
James T.
Marketing Director · SaaS Company
