Hello, @seoraketten 

I have checked your site in the Google Page insights tool. There is a low score on your website. It needs to be improved, especially on mobile devices.

As I can see your website is having very heavy load with Largest Content Paint and Total Blocking Time.

Below are some factors that might impact the speed of your online store, and how you can address them.
In order to Improve website speed we need to:
- Remove unnecessary code on a high priority basis.
- Compressed images or Defer off-screen images.
- Web Pages need to be reduce in size.
- Reduce JavaScript execution time
- Minimize main-thread work
- Beware of excessive liquid loops
- Decrease thumbnail image size
- Weigh the benefits of installing another app


3rd Party App Code: 


  • You should remove the unused app code. It will be beneficial to your store. and makes your theme code easier to read.
  • 3rd party apps & codes which take time to load and their size. They decrease the speed.
  • Some code can be removed or reordered to improve your online store's performance. If you're not using an app, then you can remove it.
  • If you're removing an app, then consider removing the code that was added as part of the app install process. Some apps help you with this process by wrapping their code in {% comment %} tags that mention the app name.
  • Removing unused app code is a best practice that avoids running code for unused features and makes your theme code easier to read.

We’ve had the best success for our clients by working with our developers to implement the lazy sizes because it's quite complicated for non-technical people.

You need to work on the following points:

  • Pass core web vitals (important)
  • Reduce JS Payload.
  • Use Critical CSS.
  • Reduce Large Image Sizes
  • Migrate Tracking Codes To Google Tag Manager
  • Compress Images
  • Limit Third-Party JavaScript & Apps
  • Preload Web Fonts. 
  •  Use a standard web font.

    Theme Upgrade:

    Its benefits include improved loading speeds, which can help with both user experience and store conversion rates, and search engine optimization.


    How to avoid showing invisible text:


    The easiest way to avoid showing invisible text while custom fonts load is to temporarily show a system font. By including font-display: swap in your @font-face style, you can avoid Flash of Invisible Text in most modern browsers.


    If there is anything that needs to be clarified or included, please let us know.  We will surely help you. 

    Have a nice day!
