Page speed differs a lot on mobile and desktop . (Dawn)

Technical Q&A
1

Hey,

(Using Dawn theme)

I have a kinda big difference regarding page speed on mobile and desktop, mainly on product pages.

Is this normal, and does anyone know the reason for this? I’ve done some changes and managed to improve the speed a bit, but it is still kinda poor on mobile.

All the images are optimized. The main problem seems to be largest paintful content though. I’ve managed to disable lazy loading on image banners, like the one on the homepage, but didn’t really do much. Been trying to also disable lazy loading on the first product image shown, but can’t do it without disable for all of them.

Hi,

I have checked your site. Your site speed is decent. You need to optimize jQuery and Google tag script that takes time to load. Both are under longest threads.

Let me know if you have any questions.

Thanks.

Please have a look at my signature if the information is helpful to you.

Hi,

Thanks for the reply.

I’m not sure on how to do that though. For ga4 as example, i’m only using the global site tag, nothing more. Isn’t it weird that it slows down the site so much or have i implemented it wrong?

Simply pasted it in theme.liquid right below

Update

Realized I have GTM installed, but no tags or triggers. I deleted the container now and got the page speed up by a little bit, but it’s still saying that the global tag is slowing down a lot it seems. Shouldn’t pasting the global tag be the best way to implement GA?

Hi,

If you are not using the GTM just delete this.

I have checked your website, you need to minify your header and footer as well.

Thanks
