Hi, I am new to shopify and just learning about speed scores. Can someone shed some light on why my mobile speed score is SO much lower than my desktop speed score? I'm really confused by this. Thank you!!
Solved! Go to the solution
It's normal to have a slower mobile loading speed than desktop because mobile devices have slower processors compared to desktops.

Hi @pickwickandelm, I'm Richard - CRO Expert of PageFly
Mobile PageSpeed scores vary primarily because of these variables from desktop PageSpeed scores: Mobile computers typically have slower processors. At a slower pace, PageSpeed Insights activates the cell network. There are device-specific CSS rules for mobile devices (re-sizing images, viewport size, etc.). That's the reason why your mobile score is lower than your desktop one.
Here are some tips I think would be super useful to better your mobile speed:
1. Use compressed images.
Note the size of your photo files. The optimal weight of the uploaded images shouldn’t exceed 150-200 KB. In order to compress images online, you can use free tools like jpegmini.com.
2. Simplify your web design.
3. Keep use of custom fonts to a minimum.
4. Activate Google AMP.
AMP – Accelerated Mobile Pages – is an open-source coding standard that allows you to design mobile friendly websites. AMP enables fast web page rendering, even when the network connection is really slow. Implementing it can significantly increase the users’ convenience and speed up the website loading time.
5. Minimizing the number of redirects on the site
6. Minifying the codeCode minification means simplifying the code and getting rid of any unnecessary characters without changing the functionalities and operation. It also improves the website loading time. By deleting the extra part of the code, you reduce the page weight which results in speeding up the loading time of the site.

I am facing excatly the same problem described by pickwickandelm. I have talken some screenshots again today and they are telling me, that there are obviously some problems, however I am not an IT person. My question is: Could you please have a look at those screenshots and check what the problems are and how to fix them.
I would appreciate to receive your estimation forecast on the cost and time frame to fix these problems. Obviously they only come up in the mobile version.
Since I am new to Shopify, I am asking, whether this will go on the account of the 60 min shopify support, since to my understanding the problems are connected to the shopify Theme (Debut). Is that correct ? If so, how to arrange that with Shopify ?
Thank you for your response
