Tip: Optimise images

We estimate potential to save at least 2.5MB* by optimising images:

770w_Uxbridge_Road_f... is 852kB and could be 574kB smaller
770w_Baylis_Park_dum... is 692kB and could be 477kB smaller
770w_Money___iStock_... is 526kB and could be 411kB smaller
770w_Seized___Tamari... is 486kB and could be 360kB smaller
770w_Zipp_scooter.jpg is 426kB and could be 295kB smaller
1180w_Homepage_image... is 299kB and could be 185kB smaller
770w_SB_atrium_crop_... is 296kB and could be 185kB smaller
375w_Will_Tuckley_sn... is 68kB and could be 48kB 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:

js?id=G-3NT4S8Y2WX is 99kB
cookieControl-9.x.min.js is 95kB
js?id=UA-25904134-1&l=dataLaye... is 74kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

Civic uses 96kB
Google Tag Manager uses 173kB
Google Fonts uses 46kB
Google 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.
