The authors of daily.co, a site built entirely in Webflow, share their learnings on optimizing their Google PageSpeed score. They started with a slow mobile score of 51 and aimed to improve it by deferring off-screen images, setting a fallback font for their custom typeface, and delaying the load of their Intercom Messenger widget. These changes helped them shave seconds off their page load time and improved their mobile score to 90. The authors emphasize that optimizing one's site is specific to each site and its pages, and provide resources such as Webflow's font-display post and image load post for more information on implementing these optimizations.
