Very interesting article for everyone struggling with cookie banners impacting their #CoreWebVitals: x.com/DebugBear/stat…
Cookie banners can cause web performance and Core Web Vitals issues. Check out this new article to learn about different problems and what you can do about them. debugbear.com/blog/cookie-co…
🔖 Blogpost Tip: Bringing site speed metrics back to GA4 (by @thyng) #googleanalytics #ga4 #webperf

💡#Webperf TIP: Don't forget to make sure that common marketing parameters are included in your caching rules (fbclid, gclid, msclkid, utm_ parameters, etc.) Otherwise the website might load significantly slower for users coming through your marketing campaigns! #Webperformance
This company had Facebook #ads running... but someone forgot to add fbclid to the #caching rules, ouch. 😬 Luckily we've spotted this right away with some #realusermonitoring
📗 Some nice reading for the weekend: A new article from @gtmetrix about Slow TTFB issue and who to talk to about it - Developer or the Hosting Provider? gtmetrix.com/blog/slow-ttfb… #webperf
What do you imagine when you see the job title "Web Performance Manager"? A marketing job role, or rather something #webperf-related?
💡#webperformance Tip! Scrollbars can cause unwanted layout shifts and influence the CLS metric. You can fix that using the `scrollbar-gutter:stable` CSS property: developer.mozilla.org/en-US/docs/Web… #cls #webperf #pagespeed
After implementing "scrollbar-gutter:stable" the amount of page-views with a layout shift dropped nicely! #AimForZero #CLS #WebPerf
📺 #WebPerf Video Recommendation for Sunday afternoon: Maciek Palmowski (@palmiak_fp) made a very interesting interview with @HenriHelvetica about web performance and next steps in the web evolution. Including Q&A section at the end... youtube.com/watch?v=SL6wdc…
Or if you prefer to work with CLI - you can use directly the SVGO tool: github.com/svg/svgo
💡#Webperf tip: Decrease the file size and complexity of your SVG files. SVG Files (especially when exported from graphic editors) contain a lot of unnecessary metadata and elements that are not needed. You can use a tool called SVGOMG to minify them: github.com/jakearchibald/…
🔧 Great news! A new Performance Insights panel! #webperf
⚠️ Spoiler alert! A new Performance Insights panel is coming in Chrome Canary. 👀 It's experimental, so... give it a try and share with us your thoughts! goo.gle/devtools-perfo…
💡A great #webperf tip from @Steve8708:
Performance tip: make your page load feel more instant by using priority hints to help the browser prioritize the most critical resources More you can do with priority hints in 🧵:
Today's #WebPerf pro tip: don't lazy load LCP images! This one crept in on one of my client's sites, discovered because LCP started creeping up on a key template.
📗 Great #webperf book tips:
Books that have helped and continue to help me understand Web Performance 📚 #WebPerf #Performance #WPO #ImagePerf #PerfCrafters 🧵
FYI: Core Web Vitals for error pages are not counted in the Chrome UX Report (CrUX):
@blue2blond @KamilHavlicek @ChromeUXReport @philwalton 404 and other error pages are not counted. Here's the documentation on the code that does the filtering: chromium.googlesource.com/chromium/src/+…
Join the journey with us and @RealWebPageTest to see where we're headed next in #observability and #webperf. We're hiring 👉 bit.ly/3xEDkJi #Catchpointer #CatchpointCrew #monitoring #hiring #career #winningteam
Let's start a thread with #webperf related job opportunities:
Does anyone know?
Question about @ChromeUXReport: Are visits of 404 error pages included in the CWV metrics? For example, what if the 404 error page has an incredibly huge layout shift - will this be counted in the CLS metric? #WebPerformance #PageSpeedInsights
💡#Webperf tip/reminder: Monitor closely all the changes published in your Google Tag Manager and their influence on the web performance:
A Shopify merchant was struggling to explain why their daily lighthouse speed scores dropped 5 days ago, despite: • NO code changes • NO new apps Can you spot when the marketing team made changes with Google Tag Manager? Lesson: Marketing ships code changes too!
