  Tip: Optimise images

  We estimate potential to save at least 192kB* by optimising images:

  1. precious-omorogbe.xa... is 169kB
  2. jan-start.jpg is 164kB and could be 60kB smaller
  3. library-dec23-hero.jpg is 138kB
  4. international-tile-5... is 116kB and could be 12kB smaller
  5. 102823d-student-conn... is 112kB and could be 82kB smaller
  6. chi-launch.jpg is 84kB and could be 25kB smaller
  7. london-2022.jpg is 70kB and could be 15kB smaller

  First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

  Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

  *This is an estimate from Google PageSpeed and you may get much better results than this in practice.

  Tip: Large files

  Aside from images, here are the biggest resources:

  1. desktopEmbedded.js?version=10.... is 259kB
  2. gtm.js?id=GTM-WCPGGV is 125kB
  3. .jsonp?v=2.0&df=undefined&b=un... is 121kB
  4. main.MTdjYzNiZDU2MA.js is 109kB
  5. js?id=G-LM33TK263R&l=dataLayer... is 93kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 218kB
  2. TikTok uses 149kB
  3. LivePerson uses 500kB
  4. cookiepro.com uses 106kB

  Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
