    Tip: Optimise images

    We estimate potential to save at least 4.8kB* by optimising images:

    1. homepage-pg-courses-... is 106kB
    2. uni-of-the-year-140x... is 13kB and could be 4.8kB 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. base.js is 784kB ×2
    2. js_8w0GIYptJbt88qc4f-m3FEHI1oJ... is 183kB
    3. eQTi6MVEjNdZNpDt.json is 139kB ×2
    4. main.MTdjYzNiZDU2MQ.js is 111kB
    5. gtm.js?id=GTM-5TFR6G is 107kB
    6. www-embed-player.js is 99kB ×2

    There are 3 duplicate resources included on the page.

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. YouTube uses 2.1MB
    2. userway.org uses 386kB
    3. Google Tag Manager uses 401kB
    4. TikTok uses 151kB
    5. Facebook uses 170kB
    6. Other Google APIs/SDKs uses 68kB
    7. Hotjar uses 65kB
    8. Crazy Egg uses 56kB
    9. Google Fonts uses 46kB
    10. Cloudflare CDN uses 31kB

    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.
