Page Speed Testing The Right way

🎯 Key Takeaways

• Not all speed test tools are created equal. Tools like Pingdom or GTmetrix can provide inaccurate results.
• The two most reliable tools are Google's PageSpeed Insights (which uses Lighthouse) and WebPageTest.org for more advanced analysis.
• Before you run any test, you must follow two crucial steps for accurate results:
  • Purge All Caches: Clear the cache from your WordPress plugins (like LiteSpeed, WP Rocket) and your CDN (like Cloudflare). This ensures you're testing the "fresh" version of your site.
  • Use an Incognito Window: Always run tests in a private/incognito browser window to prevent your own browser's cache and extensions from influencing the results.

🚀 Actionable Items

• When testing in WebPageTest.org for a detailed analysis:
  • Select a relevant test location and browser.
  • For mobile tests, choose a realistic connection speed like "3G Fast" or "4G" to understand why mobile scores are often lower.
  • For desktop tests, choose "Cable."
  • Always set the number of tests to 3 and check "First view & repeat view" to see both the initial load and cached performance.

• Google PageSpeed Insights
• WebPageTest.org

Backup & Restore your sites

🎯 Key Takeaways

• Before you start configuring speed optimization plugins, you must have a reliable backup. It is possible to temporarily break your site or lock yourself out of the admin area, and a backup is your safety net.
• A complete WordPress site consists of two main parts: the files (themes, plugins, uploads) and the database (where your posts, pages, and settings are stored).
• Often, a misconfiguration affects the database. Being able to restore just the database is a highly essential skill.

🧠 Applied Learning

Creating & Restoring a Database Backup

• Your Tool: The UpdraftPlus plugin (a reliable free option).
• Your Task (Backup):
  • Install and activate UpdraftPlus.
  • Navigate to Settings > UpdraftPlus Backups.
  • Click "Backup Now."
  • In the pop-up, uncheck everything except "Include your database in the backup."
  • Click "Backup Now" again. You now have a lightweight, quick backup of your site's core data.
• Your Task (Manual Restore via cPanel):
  • If you are locked out of WordPress, log in to your hosting control panel (cPanel).
  • Find and open phpMyAdmin.
  • Select your site's database from the left sidebar.
  • Click the "Import" tab.
  • Choose the database backup file you downloaded from UpdraftPlus and click "Go." Your site's settings will be restored.

🛠️ Tools & Resources Mentioned

• UpdraftPlus (WordPress Plugin)
• Hosting cPanel / phpMyAdmin
• FileZilla (FTP Client)

Configure Cloudflare

🎯 Key Takeaways

• Cloudflare is a powerful tool that acts as a CDN (Content Delivery Network) and a security layer for your site. The free plan offers significant benefits.
• Key Free Features:
  • CDN: Stores copies of your site's static files (images, CSS, JS) on over 250 servers worldwide, reducing load times for international visitors.
  • Fast DNS: Provides one of the world's fastest DNS resolvers, which can improve your initial server response time.
  • Security: Protects against common threats like DDoS attacks.
  • Free SSL & HTTP/2: Provides a free SSL certificate to enable HTTPS and allows for HTTP/2, which enables faster, concurrent file downloads.
• Crucial Warning: Be extremely cautious when enabling SSL/TLS settings like "Full (Strict)" or "Always Use HTTPS." You must have a working SSL certificate on your own server first. If configured incorrectly, you can lock yourself out of your website. When in doubt, start with the "Flexible" SSL/TLS encryption mode.

🚀 Actionable Items (Key Cloudflare Settings)

• SSL/TLS > Overview: Start with the "Flexible" setting if you're unsure about your server's SSL. Only move to "Full (Strict)" once you have confirmed HTTPS is working perfectly everywhere on your site.
• SSL/TLS > Edge Certificates: Enable "Always Use HTTPS" and "Automatic HTTPS Rewrites" only after you have confirmed your site works correctly with SSL.
• Speed > Optimization:
  • Disable the "Auto Minify" options for JavaScript, CSS, and HTML. Your WordPress performance plugin will handle this more efficiently.
  • Enable Brotli compression.
  • Enable Rocket Loader (this helps with JavaScript loading).
• Caching > Configuration: Set "Browser Cache TTL" to a long duration, like 1 month, to improve repeat visit speeds.

Compress images in WebP format

🎯 Key Takeaways

• WebP is the next-generation image format that offers much better compression than traditional JPG or PNG files, resulting in smaller file sizes and faster load times.
• To serve WebP images on WordPress, you need a plugin that can:
  • Convert newly uploaded images to WebP automatically.
  • Bulk convert all your existing images.
• Server Requirements: For these plugins to work, your server needs a modern PHP version (7.4+ recommended) with the Imagick or GD extensions enabled.

🧠 Applied Learning

Configuring a WebP Plugin

• Your Tool: WebP Converter for Media (a reliable free plugin).
• Your Task (Configuration):
  • Install and activate the plugin.
  • Go to the plugin settings.
  • Conversion Method: Choose Imagick if available; otherwise, choose GD.
  • Image Quality: 90% is a good balance between quality and file size.
  • Image Loading Mode: Choose "Via .htaccess" if your server supports it.
  • Extra Features: Enable all options except for "keep images metadata."
  • Save changes, then click "Regenerate All" to convert your existing library.
• Verification: After the process is complete and you've purged all caches, open your site in an incognito window, right-click on an image, and select "Open image in new tab." The URL should end in .webp.

🛠️ Tools & Resources Mentioned

• WebP Converter for Media (WordPress Plugin)
• WebP Express (Alternative free plugin)

Litespeed cache

🎯 Key Takeaways

• This is an all-in-one, free, and extremely powerful performance plugin, but it has one major requirement: your website must be hosted on a LiteSpeed Web Server.
• If you have a LiteSpeed server, this plugin is often the best choice, outperforming even premium options like WP Rocket.
• It handles everything: page caching, object caching, image optimization (including WebP), CDN integration, database optimization, and more.

🚀 Actionable Items (Key LiteSpeed Cache Settings)

• [General]: Enable "Guest Mode" and "Guest Optimization" for faster initial loads for first-time visitors.
• [Cache]: Enable the main cache options for pages, REST API, and PHP resources. Enable "Cache Mobile" if you have mobile-specific content or use QUIC.cloud services.
• [Object]: If your server supports Redis or Memcached, enable Object Cache for faster database queries.
• [Image Optimization]: Go to the settings and enable "Optimize Original Images," "Create WebP Versions," and "Image WebP Replacement."
• [Page Optimization]:
  • CSS Settings: Turn ON CSS Minify, CSS Combine, and Load CSS Asynchronously.
  • JS Settings: Turn ON JS Minify. Set "Load JS Deferred" to "Deferred."
  • Media Settings: Turn ON Lazy Load for images and iframes.

Wp Rocket cache

🎯 Key Takeaways

• WP Rocket is a premium, all-in-one caching plugin known for being extremely effective and easy to configure, even for non-technical users.
• It works on any kind of server (not just LiteSpeed) and is a top choice if you are willing to pay for performance and simplicity.
• Its specialty is handling complex optimizations like CSS and JS file modifications reliably on most sites.

🚀 Actionable Items (Key WP Rocket Settings)

• [Cache]: Enable caching for mobile devices.
• [File Optimization]:
  • CSS Files: Enable "Minify CSS files." Then, test enabling "Optimize CSS delivery" (which generates Critical CSS) and "Remove Unused CSS." Check your site carefully after enabling each advanced option.
  • JavaScript Files: Enable "Minify JavaScript files." Then, test enabling "Load JavaScript deferred."
• [Media]: Enable lazy load for images, iframes, and videos. Also, enable "Add missing image dimensions" to help prevent CLS.
• [Preload]: Activate preloading and sitemap-based cache preloading to ensure your site is always fast for visitors.

3 Plugin Combo technique

🎯 Key Takeaways

• What if you're not on a LiteSpeed server and don't want to buy a premium plugin like WP Rocket? You can still get excellent results.
• This technique uses a combination of free plugins that each specialize in one area of optimization.
• The Combo:
  • A Caching Plugin: W3 Total Cache or Breeze to handle page, browser, and object caching.
  • A File Optimization Plugin: Debloat to handle minification, deferring JavaScript, and removing unused CSS.
  • A Font Optimization Plugin: OMGF (Optimize My Google Fonts) to host Google Fonts locally and ensure they load efficiently.
  • (and) An Image Plugin: The WebP Converter for Media plugin we discussed earlier.

🤔 Food for Thought

• This approach gives you tremendous power for free, but it requires more careful configuration. If your site breaks after enabling a setting (especially in Debloat, like "Remove Unused CSS"), it's likely due to a conflict with your theme or another plugin. Disable the settings one by one to find the culprit.

What if I don't get 100 Pagespeed score

🎯 Key Takeaways

• It is not important to chase a perfect 100/100 score. Getting a green score (90+) is more than enough.
• What really matters is the real-world page loading time.
• Benchmark Load Times to Aim For:
  • Cable/Desktop: Under 2 seconds.
  • 4G/Mobile: Under 3 seconds.
  • 3G/Mobile: Under 3.5 seconds.
• If you've followed the optimization techniques but your scores are still low, the problem likely lies in one of three areas:
  • Slow Hosting: This is often the biggest factor. A cheap shared server will always struggle.
  • A "Heavy" Theme: Bloated themes or drag-and-drop builders can load a lot of unnecessary code.
  • Poor Front-End Plugins: Plugins that add a lot of functionality to the front end (sliders, pop-ups, etc.) can significantly slow down your site.

🚀 Actionable Items

• If your site is still slow, first consider your hosting. Upgrading from a cheap shared plan to a quality cloud VPS like Cloudways can make a massive difference.
• Next, audit your theme and front-end plugins. Deactivate any unnecessary plugins and consider switching to a lightweight, performance-optimized theme.
