Tip: Optimise images

We estimate potential to save at least 20kB* by optimising images:

homepage_image_wall_... is 217kB
money.jpg is 125kB
river_view_2.jpg is 112kB
council_plan_montage... is 93kB
river_ouse_high_leve... is 78kB
fostering_news_banne... is 69kB
ebilling_mobile_devi... is 66kB and could be 16kB smaller
HomePage_Idling.jpg is 33kB and could be 4.4kB 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:

Tip: Limit third-party code

Here are the largest sources of third-party code:

Browsealoud uses 290kB
freeprivacypolicy.com uses 58kB
Google CDN uses 31kB
Google Fonts 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.
