Using the Batch Website Speed Test
The Batch Test tool lets you run Lighthouse-powered website speed tests across multiple URLs, devices, and geographic locations in a single session. Instead of testing pages one by one, you can analyze an entire list of URLs or a sitemap and compare performance metrics side by side. Lighthouse provides lab-based measurements for performance, accessibility, SEO, and best practices, making it useful for identifying optimization opportunities before changes reach real users.
This tool is designed for SEO professionals, developers, agencies, and website owners who need to audit large numbers of pages efficiently. By testing multiple pages across desktop and mobile devices from different locations, you can quickly identify slow URLs, compare results, and uncover performance inconsistencies across your website.
Why Use a Batch Lighthouse Test?
Manual page-by-page testing becomes time-consuming as websites grow. A batch website speed test helps you monitor performance across key landing pages, blog posts, product pages, and other important URLs in one workflow. It is especially useful for performance audits, QA testing, website migrations, redesigns, and ongoing optimization projects.
Unlike tools that rely on Chrome UX Report (CrUX) field data, this tool uses Lighthouse lab testing. This makes it ideal for debugging performance issues, validating optimizations, comparing devices, and measuring website speed from different test locations under controlled conditions.
