Tip: Optimise images

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

montpellier_gardens_... is 1.9MB and could be 1.2MB smaller
cbh_housing_300x200.... is 125kB
4752_400x266.jpg?t=1... is 111kB and could be 65kB smaller
4753_400x266.jpg?t=1... is 83kB and could be 54kB smaller
Cost_of_living_suppo... is 39kB
climate_emergency_pl... is 37kB and could be 18kB smaller
vote_recoloured.jpg is 33kB and could be 18kB 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:

m=el_main is 74kB
cmp2ui-en.js is 74kB
fontawesome-webfont.woff2?v=4.... is 67kB
vendor-list-trimmed-v1.json is 65kB
Page is 44kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

InMobi uses 224kB
Other Google APIs/SDKs uses 108kB
Google CDN uses 47kB
Google Fonts uses 35kB

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.
