Introduction
WordPress is known for its flexibility and ease of use but what if you want to take things further? If you’re looking to build high-performing, scalable, and more technically refined websites, this guide is for you. Here, we’ve pulled together 22 advanced techniques that go beyond the basics, designed for designers, developers, and power users who want to unlock the full potential of WordPress.
From custom content structures and advanced coding to performance, security, and external integrations, each section is packed with tools and methods to make your website faster, smarter, and more powerful. Whether you’re building complex menus, integrating CRMs, or turning your site into a Progressive Web App, this is your roadmap for taking WordPress to the next level.
Advanced WordPress content architecture
Custom post types
Custom post types are a powerful feature in WordPress that allow you to create content types other than the default posts and pages. By defining a custom post type, you can tailor the content management system to better fit the needs of your site. To create a custom post type, you’ll need to write some code in your theme’s functions.php file or use a plugin. Customising the admin interface for these post types helps in managing and displaying them more effectively.
Advanced custom fields (ACF)
Advanced Custom Fields (ACF) is a popular plugin that lets you add custom fields to your posts and pages. This can be incredibly useful for adding extra information or custom data that isn’t available in the default fields. Setting up ACF fields involves creating field groups and adding them to your content types. Once you’ve set up your fields, you can display this custom data in your theme by using specific ACF functions to retrieve and output the information.
Building custom taxonomies
Custom taxonomies let you create and manage unique ways to categorise content beyond the default categories and tags. By defining custom taxonomies, you can organise content in a manner that suits your site’s needs. Creating and managing these taxonomies involves writing code and configuring them in your theme. Displaying taxonomy data within your site’s templates can help users navigate content more effectively.

Custom coding and theme development
Page builders with custom code
Page builders like MaxiBlocks and Elementor make it easier to design complex layouts without needing to code. However, sometimes you’ll want to add custom code to fine-tune your designs. This can include injecting custom CSS for styling, JavaScript for added functionality, or PHP for dynamic content. Managing and maintaining this custom code requires keeping track of updates and debugging any issues that arise.
Creating custom widgets
Custom widgets allow you to add unique elements to your site’s sidebars and other widget areas. These can range from simple text widgets to more complex features like recent posts or custom HTML. Building a custom widget involves writing code in your theme’s functions.php file and defining how it should display and function. Once created, you can add and manage these widgets through the WordPress admin area.
Advanced theme development
Developing custom themes can greatly extend WordPress’s capabilities. Creating a child theme, for instance, lets you make changes to your site’s appearance without altering the original theme’s files. You can also develop custom theme features, such as unique headers and footers, by editing theme files and using WordPress hooks. This approach helps in adding functionality and customisation without disrupting the core theme.
Building custom Gutenberg blocks
Gutenberg is the block-based editor in WordPress that allows you to create complex layouts with reusable content blocks. Developing custom Gutenberg blocks enables you to add new types of content or functionality tailored to your needs. This process involves coding and registering blocks, and customising their behaviour to fit the specific requirements of your site.
Building a custom content management system (CMS)
Developing a custom CMS on top of WordPress can provide a tailored content management experience for specific needs. This involves creating custom admin interfaces and extending the default CMS functionality. By integrating these custom features with WordPress, you can create a content management solution that fits unique requirements and workflows.
Performance, security, and admin control
Optimising for speed
Website speed is important for both user satisfaction and search engine rankings. Advanced caching techniques, such as object and database caching, can significantly improve performance. Optimising your database by cleaning up unnecessary data and optimising queries can also help. Minifying and concatenating CSS and JavaScript files reduces the amount of data that needs to be loaded, further enhancing site speed.
Customising WordPress admin
Customising the WordPress admin interface can make it more efficient and tailored to your needs. This might involve modifying the dashboard to add custom widgets or statistics, adjusting the admin bar to show or hide items, or creating custom user roles and permissions. These customisations can streamline your workflow and make managing content more straightforward.
Implementing advanced security measures
Securing your WordPress site against common threats is essential for protecting your data and maintaining trust. This includes safeguarding against cross-site scripting (XSS), cross-site request forgery (CSRF), and SQL injection attacks. Setting up two-factor authentication adds an additional layer of security. Regular security audits with appropriate tools can help you keep on top of potential vulnerabilities.
Build like a pro
Advanced integrations and APIs
REST API integration
The REST API in WordPress allows you to interact with your site’s data from external applications. By making API requests, you can fetch and display data from your site in other contexts, such as mobile apps or external websites. You can also build custom API endpoints to offer specific data or functionality. Understanding how to use the REST API involves learning how to make requests and handle responses securely and efficiently.
Integrating with external APIs
Integrating with external APIs allows your site to interact with third-party services, such as payment processors or social media platforms. This involves setting up API connections and handling authentication securely. Displaying data from these external sources can be achieved by embedding or showcasing the data on your site, enhancing functionality and user engagement.
Integrating with CRM systems
Connecting your WordPress site with a CRM (Customer Relationship Management) system can improve how you manage customer interactions and data. Popular CRM plugins like HubSpot or Salesforce offer various features to integrate with WordPress. Setting up these plugins involves configuring them to capture and manage leads, track interactions, and generate reports.
Integrating with third-party analytics
Integrating analytics tools with your WordPress site allows you to track visitor behaviour and site performance. Tools like Google Analytics or Matomo provide insights into how users interact with your site. Setting up tracking involves configuring the analytics tool and integrating it with your site, while customising reports can help you analyse specific data relevant to your goals.
Advanced site features and user experience
WordPress multisite
WordPress multisite is a feature that lets you run multiple WordPress sites from a single installation. Setting up a multisite network involves configuring your WordPress installation and updating your wp-config.php and .htaccess files. Managing multiple sites from a single dashboard can simplify administration tasks. Customising multisite features allows you to tailor the network settings to fit your needs, such as adding custom themes and plugins.
Creating a membership system
Setting up a membership system on your WordPress site can turn it into a subscription-based or member-exclusive platform. This typically involves using membership plugins that manage user registrations, subscriptions, and content access. Customising membership features might include creating special areas for members and setting up content restrictions based on membership levels.
Advanced WooCommerce customisation
WooCommerce is a powerful plugin for creating online stores with WordPress. Advanced customisation of WooCommerce involves modifying templates for product pages, checkout, and cart views. You can also add custom functionality, such as product filters and extra fields, to enhance the shopping experience. Optimising WooCommerce performance is important for handling large numbers of products and transactions smoothly.
Creating and managing complex menus
Complex menus can help users navigate large sites with multiple levels of content. Building multi-level menus requires careful planning to ensure they are easy to use. Implementing custom menu walkers allows for advanced customisation of how menu items are displayed. Adding dynamic menu items can involve integrating content from various sources, making navigation more interactive.
Implementing Progressive Web App (PWA) features
Progressive Web Apps (PWAs) combine the best of web and mobile apps, offering features like offline access and push notifications. Setting up PWA functionality for your WordPress site involves using plugins or coding your own service worker scripts. Testing and maintaining these features ensures that your site performs well across different devices and conditions.
Advanced form handling
Creating complex forms with WordPress can involve features like multi-step processes and conditional logic. Plugins such as Gravity Forms or Contact Form 7 can be used to build these forms. Handling form submissions involves processing and storing data securely, and integrating with other systems if needed, such as CRM systems or email marketing tools.
Using server-side rendering (SSR) with WordPress
Server-side rendering (SSR) is a technique that can improve the performance and speed of your WordPress site by generating HTML on the server before sending it to the client. Implementing SSR with WordPress involves using tools and frameworks that support server-side rendering. Managing and optimising SSR ensures that your site remains fast and responsive while delivering dynamic content.
