Did you know that the way the network is throttled when running a page speed test can impact your metrics? 🛠️ DevTools throttling is a simple minimum request duration 🏡 Lighthouse collects data on a fast connection, then simulates a slow-down 🐻 Tools like DebugBear or WebPageTest introduce a packet-level delay Learn how each of these approaches impacts the reliability of your data: https://lnkd.in/eSdfaUFK

NEW: Reveal the CPU tasks delaying LCP for your real users, learn if your CDN is handling HTTP prioritization requests properly, get to grips with Safari's developer tools, and more!

We've rolled out an upgrade to Lighthouse 12.8.2! The new performance insights are now shown by default in the Lighthouse report. Read this article to learn more about how insights are replacing the traditional audits: https://lnkd.in/eCAaJTnz

Spotted this code on a website yesterday 😱 It's meant to reduce Cumulative Layout Shift... but it does that by hiding all page content until the DOMContentLoaded event, which fires when the browser is done parsing the HTML! That also means that all defer'd scripts are now render-blocking again. Websites hiding content with opacity:0 or visibility:hidden on the HTML tag is pretty common, it's what many A/B testing snippets do. I wrote about that here before: https://lnkd.in/dm45v9B8 But using display:none was new! We've now updated the hidden content detection logic in the DebugBear speed test to be able to detect this as well!

New real user monitoring feature: you can now view what scripts run during the initial page load process. See if CPU processing is delaying your LCP and what code has the biggest impact. https://lnkd.in/eemj7St6

Third-party code can cause a lot of CPU tasks on the browser main thread, slowing down the page load and delaying user interactions. Our new article explains how to Partytown and web workers to run third-party scripts in the background! https://lnkd.in/eG6hhQxZ

🛒 E-commerce site slowing down? 🚀 Here’s a pro tip from our latest DebugBear video: Don’t pre-load shopping cart plugins like WooCommerce on every page! Save resources by loading cart features only when users hit the cart page. 📈 This tweak boosts page speed and user experience, perfect for optimizing conversions and Google rankings.
