How can I improve my mobile website speed?

[Irena]

Hello,

Here's our product page: https://exploroproducts.com/products/at-home-marijuana-thc-drug-test-strips-kit-by-exploro. We use Debut theme. We don't have a lot of info there, all pictures are optimized with tinypng.com and we use a few apps. However, site speed on mobile is low - see the screenshot below. When first launched it was OK and then dropped to about 30. The same is with our other websites on Shopify.

• Do you guys experience the same?
• Is there a way to fix this?
• If yes, is here anyone who can fix it and how much does it cost?

Thanks!

Hi @Irena 

Yes , Low mobile page speed may kill your traffic and affect your conversion.

In order to Improve website speed we need to work on the following points:

- Weigh the benefits of installing another app
- Avoid an excessive DOM size
- Avoid Large Layouts Shift
- Serve static assets with an efficient cache policy

By fixing these issues, your website speed score can definitely improve. For more details please check and select the plan you wish to select -

Hello @Irena ,

I have checked your website product page link you have shared with us.

Scope in Optimization
1. Communicating with an app provider.
We will target the
- Theme Upgrade if there is a scope and upgraded theme available
- Render-blocking resources
- Offscreen images
- Properly size images
- Web Fonts
- Scripts which loading on the page but there is no use of it
- unused CSS
- Script - which is loaded multiple times by apps
- Removing code left from uninstalled apps

Tentative score based on assumptions and support :
1. Product Page >> For Desktop >> 80+
2. Home Page >> For Desktop >> 75+
3. Product Page >> For Mobile>> 55+
4. Home Page >> For Mobile>> 55+

Assumptions : We will upgrade theme code if needed and your theme provider should provide
an upgraded theme that reduces JS payload.
Your app provider should cooperate if there app is resulting in higher payload as these are not in
our control ( generally good reputed commercial app providers do support )
Your theme should allow different resolution images for Mobile and Desktop.

Above information is relative with Platinum plan of ours .

Hello Aibek from @Anonymous,

Thank you for your help! I would like to try your app, but after reading this review: "Originally when I downloaded this app and tried to use it, it crashed and broke my entire site..." I am afraid to do so. Can it actually hurt the website?

Thanks!

Hi @Irena 

Thanks for getting back to me. 

As we mentioned earlier in our reply to this particular customer, the problem was in the Layout app that was downloading images to the live theme. After optimization, there was a problem with this app, but this customer was thinking that our app breaks his store. We tried to explain, but there was no answer on his part. 

In our app, you can speedimize your store and then after work with JS files to postpone but with ATTENTION to not delay important files.

We have included our expertise and experience in speed optimization and you can always count on our support in any case. We will do our best.
