Elementor Speed Optimization: How We Hit 90+ Lighthouse Scores on Every Build

Every few months, someone publishes an article claiming "Elementor is slow and you should switch to [other builder]." We've been hearing this since 2019. Here's the truth after 300+ Elementor projects: Elementor can be slow. It can also hit 90+ on Google PageSpeed Insights consistently. The difference isn't the tool — it's how the tool is used.

This guide covers the exact optimization process we run on every Elementor project at DesignsLabPro. If you're managing an Elementor site with a poor PageSpeed score, most of these steps you can start applying today.

Why Elementor Gets Slow (The Real Reasons)

Before fixing the problem, understand what's actually causing it. Elementor slowness almost always comes from one or more of these sources:

• All 100+ Elementor widgets loaded on every page even when only 5 are used
• Uncompressed images — the most common culprit by a huge margin
• No caching — every visitor re-renders the page from scratch
• Slow shared hosting — Elementor can't overcome a server that takes 1.5 seconds to respond
• Too many plugins with overlapping jQuery loading
• Font Awesome icons loaded globally even if only used on one page
• Google Fonts loaded with multiple weights unnecessarily
• Render-blocking scripts — CSS and JS loaded before the page can paint
• No lazy loading on below-the-fold images

Our 10-Step Elementor Speed Optimization Process

Step 1: Baseline Audit

We run the site through Google PageSpeed Insights, GTmetrix, and WebPageTest before touching anything. This gives us a baseline score, identifies the biggest wins (look at LCP and TTFB first), and lets us measure the improvement accurately after optimization.

Step 2: Disable Unused Elementor Widgets

Elementor Pro loads all 100+ widgets on every page by default. Under Elementor > Elements Manager, we disable every widget not actively used on the site. This alone reduces CSS and JavaScript payload by 30-50% on most sites. It's the highest-leverage single change you can make.

Step 3: Image Optimization

Images account for 60-80% of page weight on most Elementor sites. We run all images through WebP conversion (serving WebP to modern browsers), apply lossy compression at 80-85% quality (imperceptible to users), and set explicit width and height attributes to prevent Cumulative Layout Shift (CLS). We use plugins like Imagify or ShortPixel for automated optimization.

Step 4: Configure Caching Correctly

We implement page caching with WP Rocket or LiteSpeed Cache depending on the hosting environment. Critical settings: cache preloading so the first visitor after cache flush doesn't experience slowness, browser caching headers for static assets, and Gzip/Brotli compression at the server level.

Step 5: Enable Elementor's Improved Asset Loading

Under Elementor > Settings > Performance, enable "Improved Asset Loading" (load assets only on pages that use them) and "Inline Font Icons" (eliminates the Font Awesome HTTP request entirely). These two settings alone can take 200-400ms off your load time.

Step 6: Optimize Google Fonts

Most Elementor sites load 3-4 Google Font weights unnecessarily. We audit which font weights are actually used, eliminate the rest, and enable font swapping so text renders immediately while fonts load. Better still — on many sites we switch to system fonts or self-host Google Fonts using tools like LocalFont.io to eliminate the DNS lookup entirely.

Step 7: Implement a CDN

A Content Delivery Network serves your static files (images, CSS, JS) from servers physically close to your visitor. For a US visitor hitting a server in Singapore, a CDN can reduce latency by 300-600ms. We configure Cloudflare (free tier works well for most sites) and enable Cloudflare's "Auto Minify" and Rocket Loader as appropriate.

Step 8: Fix Render-Blocking Resources

CSS and JavaScript that loads before the page can paint causes delayed First Contentful Paint (FCP). We defer non-critical JavaScript using WP Rocket's "Delay JavaScript Execution" feature, and ensure critical CSS is inlined. This is the trickiest step — deferred scripts can break Elementor animations if not configured carefully.

Step 9: Address Largest Contentful Paint (LCP)

LCP is the single most important Core Web Vitals metric — it measures how long the largest visible element takes to render. On most Elementor sites, this is the hero image or a large background image. Fixes: preload the LCP image using a resource hint tag, serve it at exactly the displayed size (not 3x larger), and use WebP format. A well-optimized hero image moves LCP from 4+ seconds to under 2 seconds.

Step 10: Upgrade Hosting if Needed

No amount of optimization fixes a slow server. If Time to First Byte (TTFB) is above 800ms, the hosting is the bottleneck. For Elementor sites expecting significant traffic, we recommend Cloudways (Vultr or DigitalOcean backend), SiteGround Cloud, or Kinsta. The jump from shared hosting to managed WordPress hosting can move TTFB from 1,200ms to under 200ms — that's more improvement than any plugin optimization can achieve.

Real Results From Our Optimization Work

• Healthcare practice website: 34 → 91 (Mobile PageSpeed) — 2.1s LCP improved to 1.6s
• E-commerce Elementor + WooCommerce: 41 → 88 — checkout conversion improved 23% after speed fix
• Coaching landing page: 56 → 96 — bounce rate dropped from 72% to 48% in first month
• Legal firm website (heavy images): 29 → 82 — image optimization alone accounted for 40-point gain

Frequently Asked Questions

Can you fix my existing slow Elementor site without rebuilding it?

Yes — in most cases we can significantly improve your scores without a rebuild. We offer standalone speed optimization packages. After an audit, we tell you exactly what's causing the slowness and what improvement is realistic.

What PageSpeed score is "good enough"?

Google's Core Web Vitals thresholds classify 90+ as "Good," 50-89 as "Needs Improvement," and below 50 as "Poor." We target 85+ on mobile (where most visitors arrive) and 90+ on desktop. Going from 60 to 85 is achievable on virtually any Elementor site. Going from 60 to 95 often requires hosting upgrades.

Will speed optimization break my Elementor design?

Done correctly, no. The risk area is JavaScript deferral — some animations or third-party tools break if JS is deferred aggressively. We test every optimization step in staging before applying to production, and revert any change that causes visual issues.
