Cache External Scripts vs Easy Optimizer – PageSpeed, Cache & Core Web Vitals (Unused CSS, Delay JS, Lazy Load)

Often when trying to optimize the Google Pagespeed score, there is one script which still causing the ‘Leverage browser caching’ rule popping up: Google’s own gtag.js and/or analytics.js file… With this plugin you will be able to cache this file on your local server and enable browser caching for longer than 2 hours. The plugin will check every day if there is a newer version of the file to keep the cache up to date.

Easy Optimizer is a free, all-in-one WordPress speed optimization plugin that can take the place of the 3–5 separate speed plugins most sites run today. One cache plugin. One dashboard. No premium upsells for core features. Prefer to keep your current cache plugin? You can also turn off the modules that overlap and use just the tools you want (see the FAQ). Every toggle maps to a specific Google Lighthouse recommendation — enable it, save, and your Core Web Vitals (LCP, CLS, INP) improve immediately. Features you don’t enable never touch your page load. Core Features Full Page Caching: Achieve sub-millisecond TTFB with static HTML generation and separate mobile/desktop caches. Includes automatic sitemap-based preloading. Remove Unused CSS: Automatically strips unnecessary styles, generating a slim, per-page-type stylesheet to eliminate render-blocking resources. Delay & Defer JavaScript: Improve INP and reduce total blocking time by delaying script execution until user interaction, or deferring them natively. Smart Lazy Loading: Defers offscreen images, iframes, videos, and background images. Automatically adds missing width/height attributes to fix layout shifts. Automatic LCP Preload: Detects and preloads your Largest Contentful Paint image dynamically for instant visual loading. Prefetch Pages: Pre-fetches links as users hover over them, making your site feel like an instant single-page application. Font Optimization: Injects font-display: swap automatically to ensure text remains visible during webfont loads. Bloat Removal: 15 one-click toggles to safely remove unused WordPress core scripts and features. Database Cleanup & Optimization: Schedule automatic cleanups of revisions, auto-drafts, trashed posts, spam, and transients — each with a pre-cleanup snapshot so you can restore safely. The built-in Autoload Health auditor finds the heaviest options loaded on every page and lets you switch off the ones you don’t need, directly resolving the WordPress Site Health warning “Autoloaded options could affect performance.” Heartbeat & Cron Manager: Take control of server resources by limiting WordPress Heartbeat frequency and throttling WP-Cron execution directly from the dashboard (no wp-config.php edits required). View, run, or delete scheduled cron events. Cloudflare Integration: Automatically purge your Cloudflare edge cache (tag-based or full zone) whenever the page cache clears. Test your API connection instantly without saving credentials first. Hosting Integrations: Auto-detects your environment to automatically purge server-level cache on managed hosts including Kinsta, WP Engine, SiteGround, Cloudways, GridPane, RunCloud, SpinupWP, Rocket.net, and WordPress.com. Accessibility & SEO Fixes: Automatically resolves common Lighthouse accessibility warnings in real-time, such as missing form labels, ARIA tags, and un-crawlable links. PageSpeed Speed Test: Run a Google PageSpeed test right from your dashboard and see your score with and without Easy Optimizer, side by side, for both mobile and desktop. Includes Core Web Vitals (LCP, CLS, INP). Works out of the box with no setup, or add your own free Google API key for unlimited tests. Backend Analyzer: Find what slows your site down behind the scenes. Profile any page (or your admin area) on demand to see which plugins, themes, and database queries take the most time. Basically, find slow plugins and themes. Nothing runs on your real visitors, so there is no added overhead.
