Get Started

Monitor every page, not just the homepage

Import your whole sitemap in one click

Point LoadFocus at your sitemap.xml and pick the pages to monitor.

We fetch your sitemap and list its URLs: filter the list, select the pages you care about, and one monitor per page is created with the location, device and schedule you choose. Index sitemaps, gzipped sitemaps and plain text lists are supported, and pages you already monitor are detected so re-importing never creates duplicates.

How sitemap import works

Monitor pages behind a login

Staging environments, admin dashboards and member areas, monitored like any public page.

Each monitor can send HTTP authentication with every audit: Basic Auth, a Bearer token or a custom header such as a session cookie. Credentials are removed from stored results before anything is displayed or shared.

Frequently Asked Questions

Quick answers about page speed monitoring with LoadFocus.

What is page speed monitoring?

Page speed monitoring runs automated Lighthouse audits against your web pages on a schedule and stores the results, so you can track Performance, SEO, Accessibility and Best Practices scores over time and catch regressions when they happen.

How do I monitor all pages of my website at once?

Use the sitemap import: paste your sitemap.xml URL, LoadFocus fetches it and lists the pages, you filter and select the ones to monitor, and one monitor per page is created in a single step. Index sitemaps, gzipped sitemaps and plain text URL lists are supported.

Can I monitor pages that are behind a login?

Yes. Each monitor can send HTTP authentication with every audit: Basic Auth, a Bearer token or a custom header such as a session cookie. Credentials are removed from the stored results.

How often do the monitors run?

You choose the schedule per monitor: hourly, every 6, 12, 24 or 48 hours, or weekly. Every scheduled run is kept in the history so you can compare any two runs.

Which metrics does LoadFocus track?

Every audit captures the Lighthouse categories (Performance, SEO, Accessibility, Best Practices, PWA) plus Core Web Vitals and timing metrics such as Largest Contentful Paint, Cumulative Layout Shift, Total Blocking Time, First Contentful Paint, Speed Index and Time to Interactive.

How do I get notified when my website slows down?

Create alerts on any score or metric and connect Email, Slack or Microsoft Teams channels. When a scheduled run crosses your threshold, LoadFocus notifies you with a link to the full report.
