I have been trying to improve my Shopify Dawn website speed for better Google rankings (reducing the top image size, removing some custom css), but couldn’t reach an improvement.
If it’s not hard for anyone to take a look, I would very much appreciate it.
Yeah the Dawn theme is already pretty optimized out of the box so you’re probably hitting diminishing returns. The biggest speed killers are usually apps and custom sections more than the theme itself. What apps are you running and how many custom sections do you have on the homepage?
Uninstall any apps you don’t use or that aren’t relevant to your business.
Optimise by uploading images in WebP format (see attached screenshot). Smaller file sizes with the same quality mean faster loading times. I hope your project goes really well!!
