11. How do you convert a static HTML site into a WordPress theme?
To convert a static HTML site into a WordPress theme, you split the HTML into multiple PHP files following the WordPress template hierarchy (header.php, footer.php, index.php, etc.). Then, replace static content with WordPress template tags like the_content() and wp_head(). You’ll also enqueue CSS/JS files using functions.php. This approach keeps the site’s design but makes it dynamic, SEO‑friendly, and easier to manage through the WordPress admin.
12. Explain WordPress hooks: actions vs. filters.
Hooks let developers modify WordPress without editing core files. Actions execute custom functions at specific events (e.g., wp_enqueue_scripts). Filters modify data before it’s output (e.g., the_content). They improve flexibility, SEO customization, and maintainability. Using hooks keeps your site update-safe while allowing custom features like adding schema markup or modifying metadata.
13. How do you register and enqueue styles and scripts?
In WordPress, you use wp_enqueue_style() for CSS and wp_enqueue_script() for JS inside the functions.php file. Enqueuing ensures scripts load only when needed, prevents conflicts, and allows WordPress to manage dependencies. For SEO, proper script loading improves page speed, which helps rankings. Always enqueue rather than hardcoding files in templates.
14. Describe WP_Query vs. get_posts.
WP_Query is a powerful class for custom queries with advanced parameters like pagination and meta queries. get_posts is a simplified function returning an array of posts without pagination. For SEO‑driven websites, WP_Query is often preferred for flexibility, such as pulling specific content types for landing pages.
15. How do you create a custom widget?
You can create a custom widget by extending the WP_Widget class in a plugin or theme. This involves defining widget output, form fields, and update methods. Custom widgets enhance user engagement and SEO, such as adding “Featured Posts” or “Popular Categories” to sidebars.
16. What are must‑use (MU) plugins?
MU plugins are auto-loaded plugins placed in the /mu-plugins/ folder. They can’t be deactivated from the dashboard and are useful for essential functionality like security, caching, or SEO tracking scripts. They’re ideal for maintaining critical features across multisite networks.
17. How do you handle theme customization via child themes?
Child themes allow you to modify a parent theme without losing changes during updates. You create a new theme folder with a style.css referencing the parent. Customization is done in template files, stylesheets, or functions.php. This is critical for SEO because updates won’t break site structure.
18. Explain security best practices: sanitization, nonces, SSL.
Sanitization ensures user input is safe using functions like sanitize_text_field(). Nonces verify request authenticity, preventing CSRF attacks. SSL encrypts data transfer. These measures protect your site from hacks that could hurt SEO by causing blacklisting.
19. How do you optimize images and use a CDN?
Image optimization involves compressing files without losing quality, using responsive image sizes, and enabling lazy loading. A CDN (Content Delivery Network) serves files from global servers, reducing load time. Both improve Core Web Vitals, boosting SEO performance.
20. Describe caching strategies: object cache, page cache, transients.
Object caching stores database queries in memory, page caching saves full HTML pages, and transients store temporary data. Using plugins like WP Rocket or server‑level caching improves speed, user experience, and search rankings.
