    Tip: Optimise images

    1. 1898x555-8909-Bay-Ca... is 329kB
    2. 555x345-1484-040618_... is 110kB

    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. fa-solid-900.woff2 is 151kB
    2. gtm.js?id=GTM-5MZHZM is 122kB
    3. fa-brands-400.woff2 is 110kB
    4. main.MTdjYzNiZDU2MA.js is 109kB
    5. js?id=G-3G7SKW4487&l=dataLayer... is 96kB
    6. cc.js?renew=false&referer=www.... is 90kB
    7. js?id=AW-11012821558 is 75kB
    8. www-bundle.min.js?v=544895a92e... is 74kB

    The page uses 2 fonts which require 261kB. Could system fonts be used instead?

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. JSDelivr CDN uses 58kB
    2. TikTok uses 148kB
    3. Google Tag Manager uses 631kB
    4. imagekit.io uses 1.2MB
    5. Cloudflare CDN uses 292kB
    6. Adobe TypeKit uses 263kB
    7. Cookiebot uses 125kB
    8. Recite Me uses 73kB

    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.
