Hi,
I recently noticed issue in optimization refer to:
- HTML not minimized
- Render blocking CSS / JS
- CSS not minimized
- Javascript not minified
- Images not optimized, All images in "footer-sponsor" section not Optimized , Also the images that comes in Premium blocks on front page not Optimized too.
This greatly affects to page speed and search engines.
Whether this can be fixed in the next themes update , I'm not sure how to deal with this issue.

It cannot.
- HTML not minimized
you need plugin
- Render blocking CSS / JS
until you do not develop own script, you cannot fix this
- CSS not minimized
as far as we deliver themes that can be modified by end users, we will never minify our JS or CSS. None of plugins has CSS minified as well
- Javascript not minified

you cannot optimize image for responsive web, not on 100%. You can resize footer sponsor logos if you want, you can set different size on item images, if you want.

I recommend to check Minifier plugin (free) that can do some tricks, not sure if all of them, but we will never take any action on minification, this has minimum impact on website speed and is just for rating of websites. Negative impact on end-user that wants to modify theme/plugin is much higher.
Any kind of optimization is in your hands.

As @frosticek said, they cannot deliver the theme with minimized CSS or JS, we as a developer need to have the code in the best way possible to made some changes.

For CSS, if you need to minimize the CSS you can use http://csscompressor.com/ and update the style.css, you can use this tool https://varvy.com/pagespeed/ to know more about the CSS and JS delivery process.

For images, are you using a shared hosting? if yes, you can ask your provider to install or enable Imagick PHP, or if you are using VPS you can install Imagick, more basically modification are under the .htaccess

You can use https://gtmetrix.com/ and they will give you the optimize images just click on download and replace the zara/images/ remember that the listing images are handled by the osclass core.

This are my recommendations, my PERSONAL recommendation.

Thanks Michal,



I wanted to hear your opinion to know what to do, because optimization requires a deep analysis.
And I want to know whether the modification by my side will undermine some tips on next theme updates.

Hi Carlos,



Thank you for your helpful hints, I use a shared hosting with high performance and all possible options are enabled including Imagick PHP.
In the next few days I'll to do some modifications and we'll see how it will affect the optimization.
I hope that the more people will involved in the debate, so we can collected experiences and apply them for the best possible optimization.


Cheers
