How I Lift My Business Site With a Bunch of "Code Convincion"

This is not something high-tech nor complex but I'm so grateful passed the horrible outbreak with something joyful.

This is also not a sad story, I was so intrigued instead when remembered that time 😜.

The drawback to the past 2020 when COVID-19 outbreak. No job with a very limited budget but need to start a business ASAP to keep me alive.

Shortly... an "Online store with delivery service for the daily consumer needs" was the option. I installed WordPress on a cheap shared hosting which cost me only US$66 for the first 3 years of subscription.

Theme :

• Storefront (Free)

Plugin :

• WooCommerce (It's Free),
• LSCWP (Free),
• Free WordFence,
• Free Yoast SEO
• My Own plugin to override some functionalities with my "code of convincion" that i break into three parts.

Part 1 - to tackle the slow performance and to gain more trust 🤩

WordPress on shared hosting will surely give me a headache, it's no Problem. But what if my customer also headache? So part 1 of my "code of convincion" will help to avoid the slow performance and to convince my customer that my business is not cheap.

This code is not new, I believe everyone has seen these couple of codes since it circular around the internet.

// storefront remove gfont
add_action( 'wp_enqueue_scripts', 'tkdr_removegfont', 999);
function tkdr_removegfont() {
    wp_dequeue_style('storefront-fonts');

}
// WP & WC Optimization 
remove_action('wp_head', 'feed_links_extra', 3);
remove_action('wp_head', 'feed_links', 2);

remove_action('admin_print_scripts', 'print_emoji_detection_script');
remove_action('admin_print_styles', 'print_emoji_styles');
remove_action('init', 'smilies_init', 5);
remove_action('wp_head', 'rsd_link');
remove_action('wp_head', 'wlwmanifest_link');
remove_action('wp_head', 'adjacent_posts_rel_link_wp_head', 10);
remove_action('wp_head', 'wp_generator');
remove_action('wp_head', 'wp_shortlink_wp_head', 10);
remove_action('wp_head', 'wp_oembed_add_discovery_links');
remove_filter('comment_text', 'convert_smilies', 20);
remove_filter('the_excerpt', 'convert_smilies');
remove_filter('the_content', 'convert_smilies');
add_filter( 'emoji_svg_url', '__return_false');

add_filter( 'woocommerce_enqueue_styles', '__return_empty_array' );
add_action( 'wp_enqueue_scripts', 'dequeue_woocommerce_cart_fragments', 11);
function dequeue_woocommerce_cart_fragments() {
    if ( is_page( array( 5149, 5152, 5156, 6283 ) ) ) {
        wp_dequeue_script('wc-cart-fragments');

    }

}

add_action( 'wp_enqueue_scripts', 'child_manage_woocommerce_styles', 99 );
function child_manage_woocommerce_styles() {
    remove_action( 'wp_head', array( $GLOBALS['woocommerce'], 'generator' ) );
    if ( function_exists( 'is_woocommerce' ) ) {
        if ( ! is_woocommerce() && ! is_cart() && ! is_checkout() ) {
            wp_dequeue_script( 'wc_price_slider' );
            wp_dequeue_script( 'wc-single-product' );
            wp_dequeue_script( 'wc-add-to-cart' );
            wp_dequeue_script( 'wc-cart-fragments' );
            wp_dequeue_script( 'wc-checkout' );
            wp_dequeue_script( 'wc-add-to-cart-variation' );
            wp_dequeue_script( 'wc-single-product' );
            wp_dequeue_script( 'wc-cart' );
            wp_dequeue_script( 'wc-chosen' );
            wp_dequeue_script( 'woocommerce' );
            wp_dequeue_script( 'prettyPhoto' );
            wp_dequeue_script( 'prettyPhoto-init' );
            wp_dequeue_script( 'jquery-blockui' );
            wp_dequeue_script( 'jquery-placeholder' );
            wp_dequeue_script( 'fancybox' );
            wp_dequeue_script( 'jqueryui' );
            wp_dequeue_style( 'woocommerce_frontend_styles' );
            wp_dequeue_style( 'woocommerce_fancybox_styles' );
            wp_dequeue_style( 'woocommerce_chosen_styles' );
            wp_dequeue_style( 'woocommerce_prettyPhoto_css' );

        }

    }

}

Part 2 - to make over and to look more professional 😎

The iconic login page of WordPress will be my office entrance and it's very classic, plus footer section of the storefront theme is very ugly and very possible to degrade my business. So I changed it to convince my prospective customer that my business is professional.

Part 3 - to show functionalities and make more exclusive 😉

Part 3 the "code of convincion" is to make users think that they are exclusive. I hide the price for non-logged-in and give the price level based on product category and customer TOP (Term Of Payment).

And now my US$66 3 years of hosting is over, I renewed it with cloud service costing me US$660 for a 3-year subscription to keep my business site running. Again, I'm so grateful passed the horrible outbreak with something joyful. So I running one e-commerce blog to spread something useful to others.
