    Tip: Optimise images

    We estimate potential to save at least 1.3MB* by optimising images:

    1. article?img_id=10150... is 696kB and could be 461kB smaller
    2. concrete.jpg is 454kB and could be 28kB smaller
    3. 37724278-2cf3-4004-5... is 373kB and could be 54kB smaller
    4. 3bba80de-4f3b-0db6-a... is 298kB and could be 74kB smaller
    5. 9d8f22e3-4317-441d-8... is 234kB and could be 165kB smaller
    6. 52f0f6ed-9108-46a1-8... is 222kB and could be 149kB smaller
    7. 8997b0d8-c13b-3451-7... is 208kB and could be 63kB smaller
    8. 87b54b1f-25f5-3fab-f... is 201kB and could be 75kB smaller
    9. 5bf41f60-d489-4f73-a... is 161kB and could be 122kB smaller
    10. article?img_id=10269... is 86kB and could be 62kB smaller
    11. ed4e06c7-e2c0-db20-a... is 34kB and could be 21kB smaller
    12. b9bff75f-dccd-a1be-2... is 27kB and could be 4.7kB smaller
    13. 19a88aef-1833-df38-d... is 24kB and could be 4.7kB smaller
    14. cf09d26c-6229-29bc-b... is 21kB and could be 10kB smaller
    15. 10845bb8-53ec-9cbe-b... is 18kB and could be 5.5kB 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 786kB
    2. base.js is 784kB ×4
    3. everything.jsp?browserId=other... is 745kB
    4. cfb34e52-cb76-495c-9cf2-978306... is 510kB
    5. js_loader_modules?t=1701853729... is 406kB

    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 5.3MB
    2. Google Tag Manager uses 365kB
    3. Amazon Web Services uses 1.1MB
    4. monsido.com uses 308kB
    5. Google Fonts uses 138kB
    6. Facebook uses 134kB
    7. Other Google APIs/SDKs uses 127kB
    8. Google Analytics uses 76kB
    9. Hotjar uses 60kB

    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.
