In the next sections, we\u2019ll discuss these methods in detail, providing step-by-step instructions to help you implement JavaScript on your WordPress site smoothly and effectively.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"use-wp-code-to-add-java-script-to-word-press\">Use WPCode to Add JavaScript to WordPress<\/h3>\n\n\n\n<p>A plugin is one of the easiest and safest ways to add JavaScript to a WordPress site. It\u2019s a beginner-friendly option that allows you to manage scripts without the risk of breaking your website.<\/p>\n\n\n\n<p>WordPress plugins simplify the process, making it easy to insert, edit, or remove JavaScript code directly from your WordPress dashboard. They also help ensure your custom code remains intact even after theme updates, a common issue when editing theme files manually.<\/p>\n\n\n\n<p>One of the best plugins for adding JavaScript is <a href=\"https:\/\/wordpress.org\/plugins\/insert-headers-and-footers\/\" alt=\"Link to WordPress.org - WPCode\" title=\"WordPress.org - WPCode\" target=\"_blank\" rel=\"noopener\">WPCode<\/a>. This tool is designed to help you add custom code, including JavaScript, with minimal effort.<\/p>\n\n\n\n<p>It comes with a user-friendly interface and flexible options for inserting scripts into your site. Whether you want to run your code site-wide or only on specific pages, <strong>WPCode <\/strong>makes it easy to control where and how your JavaScript is executed.<\/p>\n\n\n\n<p>To get started, install and activate the <strong>WPCode <\/strong>plugin from your WordPress dashboard. To do this, navigate to <strong>Plugins <\/strong>\u2192 <strong>Add New Plugin<\/strong>, search for <strong>WPCode<\/strong>, then click <strong>Install Now<\/strong> followed by <strong>Activate<\/strong>.<\/p>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-01.png\" alt=\"Add JavaScript To WordPress - Install WPCode Plugin\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Install WPCode Plugin\" width=\"937\" height=\"315\" \/><\/figure>\n<\/div>\n\n\n<p>Once the plugin is active, go to <strong>Code Snippets<\/strong> \u2192 <strong>+ Add Snippet<\/strong> and click <strong>+ Add Custom Snippet<\/strong> to create a new JavaScript snippet.<\/p>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-02.png\" alt=\"Add JavaScript To WordPress - Add Custom Snippet Using WPCode\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Add Custom Snippet Using WPCode\" width=\"910\" height=\"386\" \/><\/figure>\n<\/div>\n\n\n<p>Choose your snippet\u2019s code type, which is JavaScript in this example.<\/p>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-03.png\" alt=\"Add JavaScript To WordPress - Choose Programming Language\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Choose Programming Language\" width=\"843\" height=\"340\" \/><\/figure>\n<\/div>\n\n\n<p>Next, give your snippet a meaningful name, like <strong>Add JavaScript to WordPress<\/strong>, and paste your JavaScript code into <strong>Code Preview<\/strong>. For example, you may add a simple script like:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>alert('Hello, WordPress!');<\/code><\/pre>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-04.png\" alt=\"Add JavaScript To WordPress - Add JavaScript Code to WordPress\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Add JavaScript Code to WordPress\" width=\"523\" height=\"269\" \/><\/figure>\n<\/div>\n\n\n<p><strong>WPCode <\/strong>offers two main methods for inserting your script: <strong>Auto Insert<\/strong> and <strong>Shortcode<\/strong>. With <strong>Auto Insert<\/strong>, you set the script to load automatically in specific locations, such as the header or footer.

WordPress hooks allow you to add custom functionality to your site without directly editing theme files. Let\u2019s explore the meaning of hooks and how to use them to add JavaScript to WordPress website.<\/p>\n\n\n\n<p>In WordPress, hooks are specific points in the code where you can <strong>hook<\/strong> your custom functions. They let you add or modify functionality without changing WordPress core files. <strong>Action hooks<\/strong> are a type of hook that allows you to execute code at specific times, like when a page is loading.<\/p>\n\n\n\n<p>For example, you can use the <strong>wp_head<\/strong> and <strong>wp_footer<\/strong> action hooks to include JavaScript in the footer or <a href=\"https:\/\/www.hosted.com\/articles\/edit-header-in-wordpress\/\" alt=\"Link to Hosted.com Tutorials - How To Edit Header In WordPress With Site Editor and Customizer\" title=\"Hosted.com - How To Edit Header In WordPress With Site Editor and Customizer\" target=\"_blank\" rel=\"noopener\">header of your site<\/a>. These hooks are essential because they help you load scripts in the correct place and avoid conflicts with other plugins or themes.<\/p>\n\n\n\n<p>Use these hooks by adding code to your active theme\u2019s <strong>functions.php<\/strong> file. You can access this PHP file using an FTP client, your <a href=\"https:\/\/www.hosted.com\/knowledgebase\/cpanel\/use-cpanel-file-manager\/\" alt=\"Link to Hosted.com KBs - How To Use cPanel File Manager\" title=\"Hosted.com - How To Use cPanel File Manager\" target=\"_blank\" rel=\"noopener\">hosting provider\u2019s File Manager feature<\/a>, or by navigating to <strong>WordPress Dashboard<\/strong> \u2192 <strong>Appearance <\/strong>\u2192 <strong>Theme File Editor<\/strong> \u2192 <strong>functions.php<\/strong>.<\/p>\n\n\n\n<p>We recommend using a child theme rather than modifying the theme files directly. If you\u2019re a Hosted\u00ae user, you can edit and <a href=\"https:\/\/www.hosted.com\/articles\/upload-a-document-to-a-website\/\" alt=\"Link to Hosted.com Tutorials - How To Upload A Document To A Website Using WordPress And File Manager\" title=\"Hosted.com - How To Upload A Document To A Website Using WordPress And File Manager\" target=\"_blank\" rel=\"noopener\">upload files<\/a> to your child theme directory using the Hosted\u00ae File Manager.<\/p>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-07.png\" alt=\"Add JavaScript To WordPress - Use Built-in Editor of Hosted\u2019s cPanel to Edit Files Directly\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Use Built-in Editor of Hosted\u2019s cPanel to Edit Files Directly\" width=\"696\" height=\"358\" \/><\/figure>\n<\/div>\n\n\n<p>Once you access the <strong>functions.php<\/strong> file, you can add JavaScript to WordPress site as follows:<\/p>\n\n\n\n<p><strong>Add JavaScript to WordPress Header with wp_head<\/strong><\/p>\n\n\n\n<p>The <strong>wp_head<\/strong> hook runs in your website\u2019s <strong>&lt;head&gt;<\/strong> section. You can use it to include JavaScript; this needs to load before the page content, like analytics tracking scripts.<\/p>\n\n\n\n<p>Here\u2019s an example of adding JavaScript using the <strong>wp_head<\/strong> hook:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function add_custom_js_to_header() {\necho '&lt;script>console.log(\"JavaScript in Header\");&lt;\/script>';\n}\nadd_action('wp_head', 'add_custom_js_to_header');<\/code><\/pre>\n\n\n\n<p>By default, the snippet will be loaded in the <strong>&lt;head&gt;<\/strong> section of every page and applied across all posts and pages on the site.<\/p>\n\n\n\n<p><strong>Add JavaScript to WordPress Footer with wp_footer<\/strong><\/p>\n\n\n\n<p>The <strong>wp_footer<\/strong> hook runs just before the closing <strong>&lt;\/body&gt;<\/strong> tag. It\u2019s ideal for scripts that don\u2019t need to load immediately, like chat widgets or performance monitoring tools.<\/p>\n\n\n\n<p>Here\u2019s how to add JavaScript to the footer:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function add_custom_js_to_footer() {\necho '&lt;script>console.log(\"JavaScript in Footer\");&lt;\/script>';\n}\nadd_action('wp_footer', 'add_custom_js_to_footer');<\/code><\/pre>\n\n\n\n<p>This script will load in all the footers of every page of your site, improving page load times by delaying non-essential scripts.<\/p>\n\n\n\n<p><strong>Target Specific Pages or Posts<\/strong><\/p>\n\n\n\n<p>Sometimes, you only want to load JavaScript on certain pages or posts. WordPress makes this possible with conditional tags like <strong>is_page<\/strong> and <strong>is_single<\/strong>. For example, to load a script on a specific page, you can use <strong>is_page<\/strong> as follows:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function add_js_to_specific_page() {\nif (is_page('about')) {\necho '&lt;script>console.log(\"JavaScript for About Page\");&lt;\/script>';\n}\n}\nadd_action('wp_head', 'add_js_to_specific_page');<\/code><\/pre>\n\n\n\n<p>In this case, the script will only run on the page with the slug <strong>about<\/strong>. You can replace <strong>about<\/strong> with the ID or title of the page you want.<\/p>\n\n\n\n<p>However, to target a specific WordPress post, use <strong>is_single<\/strong>:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function add_js_to_specific_post() {\nif (is_single('123')) {\necho '&lt;script>console.log(\"JavaScript for Post 123\");&lt;\/script>';\n}\n}\nadd_action('wp_head', 'add_js_to_specific_post');<\/code><\/pre>\n\n\n\n<p>Here, the script will only load on the post with the ID <strong>123<\/strong>.<\/p>\n\n\n\n<p><strong>TIP: <\/strong>You can also use the block called <strong>Custom HTML<\/strong> to insert code directly into a specific WordPress page.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"enqueuing-java-script-properly-in-word-press\">Enqueuing JavaScript Properly in WordPress<\/h3>\n\n\n\n<p>So far, we\u2019ve explored how WordPress effectively adds JavaScript to specific page setups, individual posts, or even the entire website. What if you have multiple scripts? Remember, adding multiple JavaScript snippets directly to the theme file can lead to conflicts and may impact site performance.<\/p>\n\n\n\n<p>This is where enqueuing comes into the picture. Enqueuing JavaScript is the proper way to add scripts to your WordPress site. It ensures your scripts load at the right time and don\u2019t conflict with other plugins or themes.<\/p>\n\n\n\n<p>WordPress provides a built-in function called <strong>wp_enqueue_script<\/strong> to organize this process efficiently. Instead of directly embedding JavaScript into your theme files, this function helps you manage your scripts better.<\/p>\n\n\n\n<p>Here\u2019s how to enqueue JavaScript scripts in WordPress:<\/p>\n\n\n\n<p>Navigate to the following directory and create a new folder named <strong>js<\/strong>. It will help you manage if you have multiple scripts.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>public_html\/wp-content\/themes\/your-theme-name<\/code><\/pre>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-08.png\" alt=\"Add JavaScript To WordPress - Create New Folder Inside Your Theme Folder\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Create New Folder Inside Your Theme Folder\" width=\"692\" height=\"387\" \/><\/figure>\n<\/div>\n\n\n<p>Inside the <strong>js<\/strong> folder, create a dedicated JavaScript file for your custom code (in the example, we named it <strong>custom.js<\/strong>). Keeping your scripts in a separate file helps organize your site and makes future updates easier.<\/p>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-09.png\" alt=\"Add JavaScript To WordPress - Create JavaScript File\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Create JavaScript File\" width=\"563\" height=\"319\" \/><\/figure>\n<\/div>\n\n\n<p>Write your JavaScript code in the file, such as:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>console.log('Custom JavaScript is working!');<\/code><\/pre>\n\n\n\n<p>Then, save your file.<\/p>\n\n\n<div class=\"wp-block-image wp-block-image size-full\">\n<figure class=\"aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/images\/kb\/tutorials\/Tut-OS-093-10.png\" alt=\"Add JavaScript To WordPress - Add Code and Save custom.js File\" title=\"Add JavaScript To WordPress Pages And Posts: 4 Easy Ways - Add Code and Save custom.js File\" width=\"878\" height=\"108\" \/><\/figure>\n<\/div>\n\n\n<p>Next, register and enqueue the script in your theme\u2019s <strong>functions.php<\/strong> file. To do this, open the file and add the following code if you want your script to be registered for conditional use and wish to specify dependencies or a specific version:&nbsp;<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>function enqueue_custom_script() {\nwp_register_script(\n'custom-script',\nget_stylesheet_directory_uri() .

It specifies:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>&#8216;custom-script&#8217;<\/strong> is the unique name for your script, helping WordPress identify it.<\/li>\n\n\n\n<li><strong>get_stylesheet_directory_uri() . &#8216;\/js\/custom.js&#8217;<\/strong> specifies the location of your JavaScript file in the child theme folder.<\/li>\n\n\n\n<li><strong>array()<\/strong> lists any dependencies, like jQuery. Leave it empty if there are none.<\/li>\n\n\n\n<li><strong>1.0 <\/strong>is the version number, which ensures browsers always load the latest version. However, if you want to avoid caching issues, specify <strong>null<\/strong> here.<\/li>\n\n\n\n<li><strong>true<\/strong> ensures the script loads in the footer, which is recommended for faster page loads.<\/li>\n<\/ul>\n\n\n\n<div style=\"margin-top: 20px; margin-bottom: 20px;\"><div class=\"bg-primary-xxlight rounded-md mt-3 mb-3 p-3 text-center border border-primary-xlight border-2x\"><p class=\"font09 m-0\">Work smarter with <a href=\"https:\/\/www.hosted.com\/hosting\/wordpress\" alt=\"Link to Hosted.com Website - WordPress Hosting\" title=\"Hosted.com - WordPress Hosting\" target=\"_blank\" rel=\"noopener\">Hosted\u00ae\u2019s WordPress Hosting<\/a> that integrates essential features such as WP-CLI, GIT support, and SFTP access.<br>This platform is specifically tailored to simplify your workflow and provide the support you need to build and maintain high-quality websites. <\/p><\/div><\/div>\n\n\n\n<p>The <strong>wp_enqueue_script()<\/strong> function tells WordPress to include the registered script (<strong>custom-script<\/strong>) on the site.

Remember, <strong>get_template_directory_uri()<\/strong> points to the parent theme&#8217;s folder. However, <strong>get_stylesheet_directory_uri()<\/strong> points to the child theme&#8217;s folder. Use the correct function based on whether you&#8217;re working with the parent or child theme.<\/p>\n\n\n\n<p>After saving your <strong>functions.php<\/strong> file, visit your site to confirm the script works. To do this, open your browser\u2019s Developer Console (by pressing <strong>F12<\/strong>) and look for the message from your JavaScript file.

These tips will assist you in writing better code, optimizing performance, and managing your scripts effectively.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"write-clean-efficient-java-script\">Write Clean &amp; Efficient JavaScript<\/h3>\n\n\n\n<p>Writing clean, organized JavaScript is important to avoid errors and make your code easier to understand and update later. Always use meaningful variable and function names to describe what your code does. For example, instead of naming a function <strong>x()<\/strong>, name it <strong>show_alert_message()<\/strong>.<\/p>\n\n\n\n<p>Break your code into smaller, reusable functions so it\u2019s easier to debug if something goes wrong. Use comments to explain complex parts of your code. This way, if you or someone else needs to edit it later, it\u2019ll be clear what each part does.<\/p>\n\n\n\n<p class=\"has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-91b342ab9bd7a250e9be9b8d757d5cb5\"><strong>TIP: <\/strong>To learn about the debug mode, refer to the tutorial <a href=\"https:\/\/www.hosted.com\/articles\/wordpress-debug-mode\/\" alt=\"Link to Hosted.com Tutorials - WordPress Debug Mode - How to Enable It and Fix Errors\" title=\"Hosted.com - WordPress Debug Mode - How to Enable It and Fix Errors\" target=\"_blank\" rel=\"noopener\">WordPress Debug Mode: How to Enable It &amp; Fix Errors<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"always-test-java-script-code\">Always Test JavaScript Code<\/h3>\n\n\n\n<p>As we discussed, always test JavaScript code in a staging environment before adding it to your live WordPress site. Here, you can safely test changes without affecting visitors. If you use <a href=\"https:\/\/www.hosted.com\/hosting\/wordpress\" alt=\"Link to Hosted.com Website - WordPress Hosting\" title=\"Hosted.com - WordPress Hosting\" target=\"_blank\" rel=\"noopener\">Hosted\u00ae\u2019s WordPress Hosting<\/a>, you\u2019ll get this feature on all plans.<\/p>\n\n\n\n<p>Remember, testing your code ensures it works as expected and doesn\u2019t cause problems with other parts of your site. After testing, double-check everything (especially interactive elements like forms or buttons) to ensure they function properly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"minify-java-script-files\">Minify JavaScript Files<\/h3>\n\n\n\n<p>Minifying your scripts is especially helpful when using the <strong>WordPress add JavaScript to specific page<\/strong> functionality; it reduces file size and speeds up page load times. This removes unnecessary spaces, comments, and extra characters from your code. Smaller file sizes mean quicker downloads for users, improving website performance and user experience.<\/p>\n\n\n\n<p>You can use tools like UglifyJS, Terser, or online services like Minifier to minify your scripts. If you prefer plugins, try Autoptimize or WP Rocket, which can automatically minify JavaScript files on your WordPress site.<\/p>\n\n\n\n<h3 class=\"wp-block-heading h4\" id=\"use-version-control\">Use Version Control<\/h3>\n\n\n\n<p>Version control is a system that tracks changes in your code over time, making it easier to collaborate with others and roll back to earlier versions if something breaks. A popular version control system is Git, which lets you create a repository to store and manage your code.<\/p>\n\n\n\n<p>Using Git, you can experiment with new features or fix bugs without worrying about losing your previous work. It\u2019s useful for teams working on the same project, as everyone can see changes, add comments, and merge their updates seamlessly.<\/p>\n\n\n\n<p>Follow these best practices to keep your JavaScript clean, efficient, and easy to manage. These tips improve your workflow and create a smoother, faster user experience.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\">\n<a href=\"https:\/\/www.hosted.com\/hosting\/wordpress\" alt=\"Link to Hosted\u00ae - WordPress Hosting\" title=\"Hosted\u00ae - WordPress Hosting\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.hosted.com\/articles\/wp-content\/uploads\/2025\/02\/add-javascript-to-wordpress-2-1-1024x229.webp\" alt=\"Strip Banner Text - Developer-friendly WordPress Hosting with WP-CLI, SFTP, Shell Access, and GIT.

Use the Custom HTML block to insert small JavaScript snippets. For more complex scripts, consider enqueuing your JavaScript files or using plugins that integrate well with Gutenberg, ensuring they work seamlessly with your content.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1739267262584\" class=\"rank-math-list-item\">\n<h6 class=\"rank-math-question \">Can I add external JavaScript libraries to WordPress?<\/h6>\n<div class=\"rank-math-answer \">\n\n<p>Yes, you can easily add external JavaScript libraries to WordPress. The best way is to use the wp_enqueue_script function in your theme\u2019s functions.php file. This allows you to include libraries like jQuery, Bootstrap, or custom third-party scripts while ensuring compatibility with other parts of your site.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1739267263290\" class=\"rank-math-list-item\">\n<h6 class=\"rank-math-question \">Does WordPress support JavaScript?<\/h6>\n<div class=\"rank-math-answer \">\n\n<p>Yes, WordPress fully supports JavaScript. You can add JavaScript to your site in various ways, such as through plugins, the theme\u2019s functions.php file, or by directly embedding code in pages or posts using the Block Editor. WordPress also supports popular JavaScript libraries like jQuery, which is included by default.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1739267280416\" class=\"rank-math-list-item\">\n<h6 class=\"rank-math-question \">What is the best way to add JavaScript in WordPress?<\/h6>\n<div class=\"rank-math-answer \">\n\n<p>The best method depends on your needs and technical skills. Plugins like WPCode or the Custom HTML block work well for one-time scripts. For larger or recurring scripts, use wp_enqueue_script in your theme\u2019s functions.php file, as it organizes your code and prevents conflicts.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1739267288091\" class=\"rank-math-list-item\">\n<h6 class=\"rank-math-question \">Does adding JavaScript slow down my WordPress site?<\/h6>\n<div class=\"rank-math-answer \">\n\n<p>JavaScript can slow down your website if it\u2019s not implemented properly. Scripts that block page rendering, load unnecessarily on all pages, or aren\u2019t optimized can impact performance. To minimize the impact, load scripts in the footer, use minified files, and only add JavaScript to the pages where it\u2019s needed.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<h3 class=\"wp-block-heading h4\" id=\"other-related-tutorial\">Other Related Tutorial<\/h3>\n\n\n\n<p>&#8211; <a href=\"https:\/\/www.hosted.com\/articles\/embed-a-google-form-in-wordpress\/\" target=\"_blank\" rel=\"noopener\" alt=\"Link to Hosted.com Tutorials - How To Embed A Google Form In WordPress\" title=\"Hosted.com - How To Embed A Google Form In WordPress\">How To Embed A Google Form In WordPress<\/a><\/p>\n\n\n\n<p>&#8211; <a href=\"https:\/\/www.hosted.com\/articles\/add-expires-headers-in-wordpress\/\" target=\"_blank\" rel=\"noopener\" alt=\"Link to Hosted.com Tutorials - How To Add Expires Headers In WordPress - 2 Easy Methods\" title=\"Hosted.com - How To Add Expires Headers In WordPress - 2 Easy Methods\">How To Add Expires Headers In WordPress: 2 Easy Methods<\/a><\/p>\n\n\n\n<p>&#8211; <a href=\"https:\/\/www.hosted.com\/articles\/wordpress-robots-txt\/\" target=\"_blank\" rel=\"noopener\" alt=\"Link to Hosted.com Tutorials - How To Use WordPress Robots.txt and Optimize For Search Engines\" title=\"Hosted.com - How To Use WordPress Robots.txt and Optimize For Search Engines\">How To Use WordPress Robots.txt &amp; Optimize For Search Engines<\/a><\/p>\n\n\n\n<p>&#8211; <a href=\"https:\/\/www.hosted.com\/articles\/enable-gzip-compression-for-wordpress\/\" target=\"_blank\" rel=\"noopener\" alt=\"Link to Hosted.com Tutorials - How To Enable GZIP Compression For WordPress Sites\" title=\"Hosted.com - How To Enable GZIP Compression For WordPress Sites\">How To Enable GZIP Compression For WordPress Sites<\/a><\/p>\n\n\n\n<p>&#8211; <a href=\"https:\/\/www.hosted.com\/articles\/convert-figma-to-wordpress-guide\/\" target=\"_blank\" rel=\"noopener\" alt=\"Link to Hosted.com Tutorials - How To Convert Figma To WordPress - A Step-by-Step Guide\" title=\"Hosted.com - How To Convert Figma To WordPress - A Step-by-Step Guide\">How To Convert Figma To WordPress: A Step-by-Step Guide<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p> This tutorial focuses on four easy and effective ways to add JavaScript to WordPress.
