  Tip: Optimise images

  We estimate potential to save at least 62kB* by optimising images:

  1. pg-study-565x565.png... is 225kB
  2. tot_video_poster_att... is 88kB
  3. unn-sprite.jpg is 35kB and could be 15kB smaller
  4. uoty-half-pod.jpg?mo... is 30kB and could be 19kB smaller
  5. law-student-grace-ho... is 25kB and could be 14kB smaller
  6. 270sq-black.jpg?modi... is 15kB and could be 14kB 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. common-reduced.js is 272kB
  2. Page is 229kB
  3. gtm.js?id=GTM-PKW29S is 142kB
  4. main.MTdjYzNiZDU2MQ.js is 113kB
  5. js?id=G-GZ3Q7PNF2K&l=dataLayer... is 98kB
  6. style.min.css?v=202311141103 is 86kB
  7. otBannerSdk.js is 86kB
  8. js?id=DC-5272403 is 68kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Google Tag Manager uses 308kB
  2. TikTok uses 152kB
  3. cookiepro.com uses 140kB
  4. Azure Web Services uses 392kB
  5. Adobe TypeKit uses 157kB
  6. Facebook uses 94kB
  7. radiusbycampusmgmtchatemea.com uses 88kB
  8. Hotjar uses 60kB
  9. jQuery CDN uses 34kB

  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.
