Tip: Optimise images

We estimate potential to save at least 53kB* by optimising images:

cllr-farah-ninja-swo... is 1.4MB
primary-school-child... is 968kB
website-launch-monta... is 143kB
housing-in-brent.jpg... is 117kB
img_9167web.jpg?rev=... is 87kB and could be 30kB smaller
img_0055web.jpg?rev=... is 67kB and could be 24kB 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-RLFF5LRDVC&cx=c>m=45... is 152kB
gtm.js?id=G-RLFF5LRDVC is 152kB
otBannerSdk.js is 114kB
gtm.js?id=GTM-N9BKLG is 109kB
135.4755a93fc5065f342da8.js is 89kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

Google Tag Manager uses 414kB
Hotjar uses 66kB
Optanon uses 219kB
Browsealoud uses 292kB
FontAwesome CDN uses 43kB

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.
