Tip: Optimise images

We estimate potential to save at least 177kB* by optimising images:

ChristmasRecyclingIn... is 224kB and could be 105kB smaller
LWRCTCY.png is 115kB
greenwastecollection... is 113kB and could be 5.6kB smaller
ThinkCimatechange.png is 99kB
HometoSchoolTranspor... is 98kB and could be 12kB smaller
roadstwoCropped465x3... is 93kB and could be 55kB 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:

AQMiSZufGxDBhN5pKTA36CciJxTUg1... is 184kB
AQPi7OX3BPKCb4UoDETMUZ0HRq4CYc... is 165kB
js?id=G-M929RCXN30&l=dataLayer... is 113kB
gtm.js?id=GTM-M5GX3N5 is 106kB
fxR5zEfraSp.js is 94kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

Google Tag Manager uses 222kB
Facebook uses 1.7MB
Browsealoud uses 292kB

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.
