With Core Web Vitals completing its desktop rollout, publishers need to ensure compliance with first Input Delay (FID), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS).
By focusing on Core Web Vitals (CWV) optimisation, publishers will be able to maintain strong website performance, both on mobile and desktop. To optimise sites effectively, publishers need to get immediate feedback on changes and a more detailed real-user monitoring service that functions on the updated page experiences of their site visitors.
Using a real-user monitoring system can help publishers closely track their CWV scores and identify issues that require fixing. It can help publishers deliver experiences that delight users as well as power CWV performance – necessary for aiding consumer loyalty and revenue. Additionally, publishers should make sure their media assets are optimised for both desktop and mobile devices.
Along with implementing lazy loading, publishers should make sure their images are served using modern formats, with a resolution that is adequate to the size occupied on the page. To further bring the site into compliance with CWVs, publishers should keep their Above The Fold (ATF) content under 14KB and deliver it from a single domain.
