    Tip: Optimise images

    1. clearing-2023-banner... is 116kB
    2. essex-open-day-1440x... is 91kB
    3. home_video.jpg is 82kB

    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. homepage.mp4 is 4.3MB
    2. vendor.js?638351462287500227 is 221kB
    3. recaptcha__en.js is 191kB
    4. gtm.js?id=GTM-W9QBMC is 129kB
    5. main.MTdjYzNiZDU2MA.js is 109kB
    6. widget_iframe.d37472b4a6622d0b... is 106kB
    7. js?id=G-06D5HQ8SFG&l=dataLayer... is 94kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 224kB
    2. TikTok uses 148kB
    3. Hotjar uses 62kB
    4. Google CDN uses 191kB
    5. Twitter uses 135kB
    6. Facebook uses 132kB
    7. azure.com uses 47kB
    8. Google/Doubleclick Ads uses 38kB

    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.

    If you use the Twitter widget to load a timeline it may be loading as many as 100 of your recent tweets which may contain lots of images. Try setting 'data-tweet-limit' to the most recent 3.
