Uptime and SEO Monitoring, in One Place

Uptime and SEO monitoring combined means one tool answering one question: is the site still working, for users and for Google? Uptime checks tell you when a page is down. They say nothing about a noindex shipped to production, a canonical pointing at staging or a sitemap that quietly lost half its URLs, because those pages return 200 and look healthy. Deltio puts both signals in one dashboard: HTTP checks every 10 minutes plus a daily SEO scan of your sitemap, pages, SSL, domain, robots.txt and tracking tags, with email and Slack alerts, from £20 a month. One subscription instead of three, and one place to look when a client calls.

Most agencies end up split. Uptime sits in one tool, set up by whoever handles hosting. SEO checks sit somewhere else, or nowhere, and get run by hand after traffic drops. The two never share a single piece of information, and the worst incidents live in that gap.

What uptime monitoring actually sees

An uptime check is an HTTP request on a schedule. What it reports is narrow but useful:

• Up or down: the request fails, times out, or the connection is refused.
• Status code: a 500, a 502, a 503 during a deploy, an unexpected redirect chain.
• Response time: the creep from 400ms to 4 seconds that precedes an outage.
• Blocked requests: a firewall rule that starts refusing the checker, and usually Googlebot with it.

A two hour 503 is real SEO damage: Googlebot hits errors, crawl budget burns. That is the floor, not the ceiling.

What uptime monitoring never sees

Everything below returns a clean 200. Every uptime tool on the market calls these pages healthy:

• noindex in production: a staging flag ships with a release. The page loads, rankings go within days. See how to catch a noindex in production.
• Canonical rewritten: every product page suddenly points at the category. Indexation collapses.
• Title and meta description wiped: a CMS migration drops the fields. The page still renders.
• Sitemap shrinking: 4,000 URLs on Monday, 900 on Tuesday.
• robots.txt changed: one new Disallow: / line, served with a 200.
• SSL three days from expiry: valid today, nothing is down. Nothing will be, until Friday.
• Tags gone: GA4 or GTM disappears in a deploy and reporting drops to zero.

A site can be one hundred percent up and completely broken for search at the same time.

Why two subscriptions cost more than the invoice

• Price: an uptime tool, an SEO monitoring tool and an SSL tracker means three bills. Across 5 to 50 client sites it multiplies.
• Fragmented alerts: two inboxes, two Slack channels, two sets of rules. Alerts landing in different places get triaged by different people, or by nobody.
• No shared timeline: the uptime tool knows there was an outage on the 14th. The SEO tool knows the sitemap shrank on the 14th. Neither knows both.

What changes when both signals sit together

The value is the correlation, not the feature list. A long outage stops being a hosting ticket and becomes an SEO hypothesis the same day: check the affected templates, check whether the sitemap or robots.txt moved during the recovery. A traffic drop gets infrastructure context immediately, and a deploy that goes out at 3pm gets checked against both signals at 3.10pm. Our website monitoring checklist for agencies covers what belongs on that one screen.

How Deltio does it

• Uptime: HTTP checks every 10 minutes, three states (online, offline, firewall blocked), response time and status code recorded, a notification when the site goes down and when it comes back, plus a public status page for the client.
• SEO: a daily scan of the sitemap (URLs added, removed, lastmod changed, last 7 snapshots kept for diffing) and of the pages (title, meta description, H1, canonical, lang, hreflang), comparing consecutive scans so you are told what changed.
• Around it: SSL with warnings at 30 days and 1 day before expiry, domain expiry via RDAP, robots.txt changes with a line by line diff, and tags (GA4, GTM, Meta Pixel, Hotjar, Clarity, LinkedIn, TikTok) flagged when they appear, vanish or change ID.
• Alerts: email and Slack, with a toggle per event type.

From £24 a month, or £20 billed annually: less than the sum of three separate tools. If you are on a pure uptime service today, our UptimeRobot alternative comparison shows the size of the gap.

Start with one site

Add the client site that worries you most to Deltio and leave it for a fortnight. Uptime checks every 10 minutes and a daily SEO scan run side by side, and you find out what has been changing without anyone telling you. The free trial runs for 14 days.
