Hi,
An ad-hoc client of mine has reached out for advice on how to improve their website performance and load speed, and being completely honest I'm not 100% sure what to suggest aside from the obvious (remove unnecessary code and make sure images are optimised).
They have some videos embedded from YouTube on their site and ALOT of pages (mainly blogs), but the main areas flagging on the page speed test are:
Avoid large layout shifts
Minimize main-thread work
Reduce the impact of third-party code
Largest Contentful Paint element 15,480 ms
Avoid an excessive DOM size
Preload Largest Contentful Paint image Potential savings of 240 ms
Reduce unused JavaScript
Eliminate render-blocking resources
Reduce unused CSS
Serve images in next-gen formats
Reduce JavaScript execution time
They are actually failing the desktop 'Core Web Vitals Assessment' due to 'Cumulative Layout Shift' and this is the main area that I'm not sure what to suggest. (link here - https://pagespeed.web.dev/analysis?url=https%3A%2F%2Fwww.invoyage.net%2F)
They have good traffic to their website, and SEO & Accessibility is great. I wondered if anyone specialises in a purely performance aspect that I can recommend them to, or if anyone has any suggestions?
Thanks so much!
