As David Ogilvy might say, “What separates those who succeed from those who fail is often simplicity.” Yet, when it comes to optimizing WordPress sites for higher Google Page Speeds, simplicity is often buried under a mountain of missed opportunities and technical oversights. In this article, we’ll uncover the top 10 reasons your WordPress site might be struggling and how to fix them, complete with examples of what works and what doesn’t.

1. Bloated Themes
   Many WordPress users fall into the trap of choosing themes based solely on appearance. Themes packed with animations, sliders, and unnecessary features might look attractive but often come with heavy code that slows down your website.

Bad Example: A real estate website using a theme with five sliders, multiple parallax effects, and a built-in portfolio feature—none of which are essential for its functionality. The page takes 8 seconds to load, leading to a high bounce rate.

Good Example: The same website switches to a lightweight theme like GeneratePress or Astra, paired with essential plugins to add only the required functionality. The load time drops to under 2 seconds, improving both user experience and SEO.

Fix: Opt for lightweight, performance-optimized themes like GeneratePress, Astra, or Kadence. Always test the demo version of a theme using tools like Google PageSpeed Insights or GTmetrix before committing to it.

2. Unoptimized Images
   Images often constitute the largest part of a webpage’s size. Many users upload high-resolution photos directly from their camera or stock websites without compressing or resizing them, leading to slower page loads.

Bad Example: An e-commerce website uploads uncompressed, full-sized product images (e.g., 5MB each), leading to painfully slow page loads, especially on mobile devices.

Good Example: The website compresses images using ShortPixel or TinyPNG and converts them to WebP format. Product images now load quickly without noticeable quality loss.

Fix: Use tools like ShortPixel, Smush, or Imagify to compress images. Serve them in next-gen formats (e.g., WebP) and use responsive images to ensure appropriate sizes are loaded for different devices.

3. Too Many Plugins
   Plugins are a double-edged sword. While they add functionality, each plugin also increases the number of scripts, stylesheets, and database queries, which can slow down your site if not managed properly.

Bad Example: A travel blog uses over 30 plugins, including several for redundant features like social sharing. Many plugins are outdated and cause conflicts, resulting in slow load times and broken pages.

Good Example: The blog reduces its plugin count to 12, using lightweight options and combining functionalities where possible (e.g., Rank Math Pro for SEO and analytics, instead of separate plugins).

Fix: Conduct regular audits. Deactivate and delete unused plugins, and replace redundant plugins with all-in-one solutions when possible. Stick to well-coded, frequently updated plugins.

4. Lack of Caching
   Without caching, every visit to your site triggers the server to load all the files and execute all scripts, leading to slower page loads, especially for repeat visitors.

Bad Example: An online magazine loads dynamic content for every visitor without caching, resulting in slower load times as traffic increases.

Good Example: The site implements WP Rocket, enabling caching for pages, posts, and even database queries. Returning visitors experience significantly faster load times.

Fix: Install a caching plugin like WP Rocket, W3 Total Cache, or LiteSpeed Cache. These plugins store a static version of your pages and deliver it quickly to users.

5. Not Using a CDN
   If your site doesn’t use a Content Delivery Network (CDN), users far from your server may experience slower loading times due to physical distance and network latency.

Bad Example: A global fashion brand hosts its site on a single server in New York, leading to slow page loads for users in Europe and Asia.

Good Example: The brand integrates Cloudflare’s free CDN, which caches static assets like CSS, JavaScript, and images on servers worldwide. Users everywhere enjoy faster load times.

Fix: Use a CDN like Cloudflare, Bunny.net, or StackPath. This ensures static assets are delivered from the nearest server to your users.

6. Unoptimized CSS and JavaScript
   Excessive CSS and JavaScript can inflate your page size and delay rendering, negatively impacting the user experience.

Bad Example: A portfolio website loads 20 JavaScript files and 10 CSS files for animations, sliders, and interactive features. Half of these aren’t even used on all pages.

Good Example: The site minifies CSS and JavaScript with Autoptimize, combines files where possible, and defers non-critical scripts. The total page size decreases by 40%.

Fix: Minify CSS and JavaScript using tools like Autoptimize or Asset CleanUp. Defer the loading of non-critical scripts to improve rendering times.

7. Poor Web Hosting
   Your hosting provider significantly impacts your site’s speed. Shared hosting plans, while cheap, often lack the resources and performance needed for a fast-loading site.

Bad Example: A growing blog on a $3/month shared hosting plan experiences frequent downtime and load times exceeding 5 seconds.

Good Example: The blog upgrades to Kinsta’s managed hosting, which offers better resources, caching, and server-side optimizations. Page speeds improve dramatically.

Fix: Choose a reputable hosting provider like SiteGround, Kinsta, or WP Engine. For budget-friendly options, consider Bluehost or NameHero.

8. Ignoring Google PageSpeed Insights Recommendations
   Many site owners run tests on Google PageSpeed Insights but fail to act on the recommendations provided, missing easy opportunities for optimization.

Bad Example: A news site gets low scores for “eliminate render-blocking resources” and “optimize images,” but the owner takes no corrective action.

Good Example: The site uses the PageSpeed recommendations to implement lazy loading for images and defers JavaScript. Its mobile score improves from 60 to 85.

Fix: Regularly run PageSpeed Insights tests and act on recommendations such as optimizing images, leveraging browser caching, and reducing unused CSS.

9. Overloaded Databases
   A bloated database filled with post revisions, spam comments, and unused data can slow down server response times.

Bad Example: An online store with a large WooCommerce database doesn’t clean up old order data, leading to slow back-end performance.

Good Example: The store uses WP-Optimize to regularly clean the database, remove spam comments, and optimize tables. Backend speed improves significantly.

Fix: Use tools like WP-Optimize or Advanced Database Cleaner to remove unnecessary data and optimize your database tables.

10. Not Prioritizing Mobile Performance
    With Google’s mobile-first indexing, optimizing your site for mobile users is critical. Many sites, however, focus only on desktop performance.

Bad Example: A photography portfolio uses high-resolution images and ignores responsive design, leading to long load times and poor usability on mobile devices.

Good Example: The site adopts responsive design principles, compresses images, and uses a mobile-friendly menu. Its mobile PageSpeed score improves from 45 to 90.

Fix: Use responsive design, optimize images and fonts for mobile, and ensure fast loading times on mobile devices.

By addressing these top 10 issues, you’ll not only improve your WordPress site’s Google Page Speed score but also provide a faster, more engaging experience for your users.
