Google Page Speed mobile is always bad no matter what I do.

Hello,

perhaps you can help me.
I build several Websites, and with each I have this one specific Issue.
Google Page Speed check shows me, that there is a big problem with
“Ressourcen beseitigen, die das Rendering blockieren”
“Ressourcen blockieren den First Paint Ihrer Seite. Versuchen Sie, wichtiges JS und wichtige CSS inline anzugeben und alle nicht kritischen JS und Stile aufzuschieben.”

I activated all important Performace settings in Enfold, installed a Cache Plugin and added this Code to “functions.php”:

function remove_head_scripts() {
    remove_action(‚wp_head‘, ‚wp_print_scripts‘);
    remove_action(‚wp_head‘, ‚wp_print_head_scripts‘, 9);
    remove_action(‚wp_head‘, ‚wp_enqueue_scripts‘, 1);
    add_action(‚wp_footer‘, ‚wp_print_scripts‘, 5);
    add_action(‚wp_footer‘, ‚wp_enqueue_scripts‘, 5);
    add_action(‚wp_footer‘, ‚wp_print_head_scripts‘, 5);
}
add_action(‚wp_enqueue_scripts‘, ‚remove_head_scripts‘);

remove_action(‚wp_head‘, ‚print_emoji_detection_script‘, 7);
remove_action(‚wp_print_styles‘, ‚print_emoji_styles‘ );

Why does the mobile Website still performs so bad?

Cheers
Monika
