WPO Tweaks & Performance Optimizations

WPO Tweaks is the most complete performance optimization plugin for WordPress. It combines the best WPO (Web Performance Optimization) practices in a single easy-to-use tool. No configuration needed: activate and enjoy a faster WordPress. By default, WordPress loads several functions, services and scripts that are not mandatory and usually slow down your installation and consume hosting resources. For years I have been testing tweaks to save hosting resources and improve WordPress performance and loading times. After thousands of tests, this plugin includes my best speed and performance optimizations with a single click. With this plugin you can safely disable those annoying services, unnecessary codes and scripts to save resources and hosting costs, and speed up WordPress to get better results in tools like Google PageSpeed, Pingdom Tools, GTMetrix, WebPageTest and others. New version 2.1.x with modular architecture and enhanced reliability! NEW FEATURES V2.1.x Modular Architecture:

HOW TO VERIFY OPTIMIZATIONS ARE WORKING You can check each optimization individually to ensure WPO Tweaks is working correctly: Missing Image Dimensions: Inspect images in your browser (F12 > Elements). Images should have width="X" and height="Y" attributes even if they weren't originally coded with dimensions. Critical CSS: View page source (Ctrl+U) and look for <style id="ayudawp-wpotweaks-critical-css"> in the head section containing basic CSS rules. Deferred CSS: In source code, look for <link> tags with rel="preload" as="style" instead of rel="stylesheet", followed by <noscript> fallbacks. Google Fonts Optimization: Google Fonts URLs should include &display=swap parameter. Preconnect: Look for <link rel="preconnect"> tags in the head pointing to fonts.googleapis.com, fonts.gstatic.com, etc. DNS Prefetch: Check for <link rel="dns-prefetch"> tags pointing to external domains like gravatar.com, stats.wp.com. Lazy Loading: Inspect images (F12) - they should have loading="lazy" and decoding="async" attributes. Resource Preload: Look for <link rel="preload"> tags for your theme's CSS and critical fonts. Version Removal: Source code should NOT contain <meta name="generator" content="WordPress X.X"> or ?ver= in script/style URLs. Dashicons Removal: When logged out, source code should NOT include dashicons.min.css. When logged in, it should appear. Emojis Removal: Source code should NOT contain wp-emoji-release.min.js or emoji-related styles. Header Cleanup: Source code should NOT contain <link rel="EditURI">, <link rel="wlwmanifest">, or <link rel="shortlink">. JavaScript Defer: Most <script> tags (except jQuery) should include the defer attribute. GZIP Compression: Test at giftofspeed.com/gzip-test - should show "GZIP is enabled". Cache Headers: Check your .htaccess file for a section marked "BEGIN WPO Tweaks by Fernando Tellado" with expiration rules. Heartbeat Control: In WordPress Dashboard, open browser dev tools (F12) > Network tab. AJAX requests to admin-ajax.php with action=heartbeat should occur every 60 seconds instead of 15. Use tools like Google PageSpeed, GTMetrix, Pingdom Tools, and WebPageTest to measure overall performance improvements. Always test twice to account for caching effects. COMPATIBILITY AND EXTENSIBILITY The plugin includes multiple filters for developers:

• ayudawp_wpotweaks_critical_css - Customize critical CSS
• ayudawp_wpotweaks_preconnect_hints - Add custom preconnect
• ayudawp_wpotweaks_dns_prefetch_domains - Customize DNS prefetch domains
• ayudawp_wpotweaks_critical_fonts - Define critical fonts for preload
• ayudawp_wpotweaks_keep_xmlrpc - Keep XML-RPC if needed
• ayudawp_wpotweaks_keep_feeds - Control feeds removal Compatible with:
• Jetpack (keeps XML-RPC automatically)
• All well-coded themes
• Cache plugins (W3 Total Cache, WP Rocket, etc.)
• WordPress Multisite
• Builders (Elementor, Divi, Gutenberg)

INSTALLATION AND USE No options. Just activate the plugin and test your site speed in your favorite tool (GTMetrix, Pingdom Tools, Google PageSpeed, etc.) The plugin is completely automatic and applies optimizations safely without breaking functionality. MEASURING RESULTS Recommended tools:

• Google PageSpeed Insights
• GTMetrix
• WebPageTest Best measurement practices:
• Run at least 2 tests (first one may not show cache)
• Always use the same tool for comparison
• Measure performance over time, not just once
• Remember that no tool can replace human perception
