Tip: Optimise images

We estimate potential to save at least 261kB* by optimising images:

autumn_promenade_200... is 3.8MB
Ellenborough_House_6... is 470kB
4844_400x266.jpg?t=1... is 168kB and could be 123kB smaller
4843_400x266.jpg?t=1... is 142kB and could be 108kB smaller
climate_emergency_pl... is 38kB and could be 18kB smaller
letterbox.jpg is 20kB and could be 11kB 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:

Page is 114kB
cmp2ui-en.js is 105kB
m=el_main is 76kB
vendor-list-trimmed-v1.json is 70kB
fontawesome-webfont.woff2?v=4.... is 67kB

Tip: Limit third-party code

Here are the largest sources of third-party code:

InMobi uses 295kB
Other Google APIs/SDKs uses 110kB
Google CDN uses 47kB
Google Fonts uses 36kB

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.
