User Documentation A fast, accessible, error-free site keeps visitors around and ranks better in search results. This section covers the tools Joomla provides — and a few external services worth pairing with them — for catching accessibility problems, broken links, slow-loading pages, and server issues before they affect your visitors.
- Accessibility Checker – Joomla's built-in jooa11y plugin that flags contrast, form-label, readability, and other accessibility issues while you're creating content, so problems can be fixed before you publish.
- Managing 404 Errors – Finding broken links with tools like Google Search Central and fixing them, by redirecting the page or reinstating the missing content, before they harm your search rankings.
- Monitoring Server Health – Using tools such as Pingdom, Google Analytics, and Nagios to track uptime and response times and catch server problems early.
- Monitoring Site Speed – Reading Google Analytics' site speed reports and tools like Pingdom to see how quickly pages load worldwide and spot slow regions.
- Page Analysis – Using Google's Lighthouse tool to audit a page's performance and accessibility, and judging which of its suggestions are worth acting on.
