Monitor websites
URLradar monitors your URLs hourly over HTTP – so errors after deployments, in the database or in your infrastructure do not go unnoticed while you focus on other work.
Why URLradar?
URLradar exists because we needed the tool ourselves: at SEO-DAY GmbH we were tired of silent deployments from developers and recurring WordPress issues from auto-updates – often nobody noticed for days that status codes, page titles or canonicals were wrong. That is why URLradar covers six checks at a glance: status code, page title, canonical, load speed (TTFB), PageSpeed and email alerts. Stored URLs are monitored automatically every hour; when something deviates, an email follows – without watching every address manually.
Status code check
URLradar checks the HTTP status of each stored URL every hour. If the code deviates from 200 – e.g. 301, 404 or 500 – you see the issue in your dashboard right away.
Content check: page title
The content checker compares the actual page title with your expected target. If the title changes unexpectedly after a deployment or CMS update, you notice immediately.
Content check: canonical
URLradar also checks the canonical URL: does the delivered canonical match your expectation, or did it change after redirect or SEO updates?
Speed check (TTFB)
URLradar measures time-to-first-byte for each URL and compares it to your limit (default 300 ms). If a page gets noticeably slower after a deployment, plugin update or hosting change, you see it in the dashboard – and get the same email alert as for status or content deviations.
PageSpeed check (Google)
URLradar checks stored URLs via the Google PageSpeed Insights API for mobile and desktop. Performance scores and Core Web Vitals appear in the history; on deviations the same email alert follows as for the other checks.
Email alert
On status code, content or PageSpeed deviations an email with the affected URL follows – without manually watching every address.
