    Tip: Optimise images

    We estimate potential to save at least 6.1kB* by optimising images:

    1. 2a08e694-365a-4a14-b... is 420kB
    2. 7EJDYnOEoy8plGer.jpg is 162kB
    3. GettyImages-17477198... is 162kB
    4. UDgCgeZ_OFRngJuv.jpg is 104kB
    5. 19d0ae5b3496605e7f6a... is 7.2kB and could be 6.1kB 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:

    1. ASCMCwRbUXXzKG1i.mp4?tag=12 is 2.6MB
    2. mr9pd8jF_10vmWBv.mp4?tag=12 is 1.2MB
    3. embed.9449.143d97ea3ade6f4824d... is 163kB ×2
    4. widget_iframe.d37472b4a6622d0b... is 106kB
    5. gtm.js?id=GTM-TJJZ6PQ is 101kB

    There is 1 duplicate resource included on the page.

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Twitter uses 5.0MB
    2. Google Tag Manager uses 271kB
    3. cloudfront.net uses 951kB
    4. Facebook uses 95kB

    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.

    If you use the Twitter widget to load a timeline it may be loading as many as 100 of your recent tweets which may contain lots of images. Try setting 'data-tweet-limit' to the most recent 3.
