@Marcos7882 ,


3rd party apps & codes which take time to load and their size . They decrease the speed.

See these points.

  • Check the assets folder of the theme and remove unused CSS and JS file
  • Check and remove unused apps
  • If your store has not installed any app you can comment {{ content_for_header }} code in theme.liquid (not recommended if you don't have knowledge about the liquid)


But the 3rd party app JS you cannot minify these files it can harm your site or maybe your store will down.


These URLs coming from 3rd Part app.


Apart from this you can solve these issues.


Ensure text remains visible during webfont load :

Preload Web Fonts. or I would suggest limiting to one and using a standard web font.

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 FOIT in most modern browsers.


Image elements do not have explicit width and height:

Always include width and height size attributes on your images and video elements. Alternatively, reserve the required space with CSS aspect ratio boxes. This approach ensures that the browser can allocate the correct amount of space in the document while the image is loading.

For eg :

<img src="puppy.jpg" width="640" height="360" alt="Puppy with balloons" />

@Marcos7882  you may not want to remove those. The tool you're looking at is a general analysis tool, not geared well for eCommerce sites that use engaging apps to increase conversions.


I recommend first optimizing your store, then making sure you don't have any old app code loading, then try to optimize your apps as much as possible.


You can use the Shopify Analyzer for a Shopify specific analysis tool to check for optimization issues (and how to fix them).


For removing old app code / optimizing apps here's a guide:
