Technical SEO and Website Performance

Don’t be blinded by the lighthouse: shift focus to core web vitals and RUM

brightonSEO April 2025

This talk is for any level of experience, you just need to be interested in Pagespeed!


This talk challenges the widespread fixation on achieving a perfect Lighthouse score and redirects focus toward metrics that actually impact real user experience. We'll explore why the perfect score doesn’t guarantee a fast, smooth experience for users and why Google prioritises CWV instead.

Through real-world examples and practical tips, we’ll show how Real User Monitoring (RUM) and CWV optimisation tools provide a clearer picture of site performance, ultimately benefiting both user satisfaction and SEO.
