If you've built a website with Elementor and then run it through Google's PageSpeed Insights, there's a good chance you were greeted by a red score somewhere between 20 and 45 on mobile. And if you're like most site owners, your first reaction was probably confusion followed by frustration — because the site looked great in the editor and seemed fine when you loaded it on your desktop.
Here's the thing: PageSpeed Insights is not measuring how the site looks. It's measuring how the site loads. And Elementor — despite being the world's most popular WordPress page builder — generates some of the heaviest, most render-blocking HTML, CSS, and JavaScript of any website building tool available today. That's not a personal attack on Elementor. It's just the technical reality of how it works.
This article will explain exactly why Elementor sites score so poorly, and what you can actually do to fix it. Not just "install a caching plugin" — real, technical improvements that will push your score into the 80s or 90s.
Why Elementor Sites Are Slow by Default
Elementor loads a lot of CSS and JavaScript regardless of what's on the page. Even a simple homepage with a hero section, a few columns, and a contact form can generate 300+ HTTP requests and load 2-4MB of assets before anything visible appears on screen. Here's the breakdown:
Elementor's CSS files are massive. The frontend.min.css file alone can be 300-500KB. It loads styles for every widget Elementor ships — even the ones you haven't used on that page. This is a systemic problem. The CSS is not split by component. You load everything for every page.
Every widget adds JavaScript. Sliders, accordions, tabs, counters, video backgrounds — each one brings its own JS file. On a typical Elementor site with 5-10 widget types per page, you can easily have 15-20 JavaScript files loading, many of them render-blocking (meaning the browser stops building the page until they finish loading).
Images are rarely optimised at source. Elementor's image widget doesn't automatically convert to WebP or enforce size limits. It's common to see full-resolution JPGs from a camera (4-8MB each) being served on a WordPress site because no one ever compressed them.
Hosting plays a big role. Shared hosting on GoDaddy, Bluehost, or HostGator introduces server-side latency — slow Time to First Byte (TTFB) — that caching can't fully compensate for. Even a perfectly optimised site will score poorly if the server takes 2 seconds to respond.
How to Actually Fix It
Step 1: Address CSS bloat. The most effective fix for Elementor's CSS problem is enabling "Improved Asset Loading" in Elementor's settings (Elementor > Settings > Advanced). This feature, introduced in Elementor 3.x, only loads the CSS for widgets that are actually used on each page. It's a straightforward toggle and can reduce CSS payload by 60-80%. Make the change on a staging site first and test every page type before pushing to production.
Step 2: Eliminate render-blocking JavaScript. Tools like WP Rocket, LiteSpeed Cache (if your host supports it), or Perfmatters allow you to defer JavaScript — meaning the browser loads the page first and runs the scripts afterwards. This dramatically improves First Contentful Paint (FCP) and Largest Contentful Paint (LCP), two of the three Core Web Vitals that feed directly into PageSpeed scores. Be careful with aggressive deferral — some scripts need to load before the page renders (analytics, anti-spam) and deferring them can break things. Test every change.
Step 3: Convert images to WebP and compress them. WebP images are typically 25-35% smaller than equivalent JPEG or PNG files with no visible quality difference. The ShortPixel or Imagify plugins handle bulk conversion of your existing library. Going forward, every uploaded image should be compressed. Large images are often the single biggest cause of slow load times — I've seen sites where simply compressing the hero image took the LCP score from 8 seconds to 2 seconds.
Step 4: Implement a proper caching stack. "Caching" means serving a pre-built HTML version of your pages instead of building them from scratch on every request. Good plugins for this include WP Rocket, W3 Total Cache (configured correctly), or LiteSpeed Cache. Beyond page caching, object caching with Redis or Memcached can significantly reduce database queries. Cloudflare (even the free tier) adds another layer of caching at the CDN edge, closer to your visitors.
Step 5: Fix your hosting. If you're on shared hosting, you've hit a ceiling. Managed WordPress hosts like Kinsta or Cloudways provide better server infrastructure, PHP 8.2+, built-in Redis, and modern HTTP/2 or HTTP/3 support. The performance difference is significant. A well-optimised site on Cloudways will consistently outperform the same site on GoDaddy.
What About Elementor's "Speed" Features?
Elementor has been working on performance and has introduced features like the Flexbox Container (which generates cleaner HTML than the old div-heavy layout), improvements to the asset loading system, and their own image optimization. These help, but they don't replace proper server-side and front-end optimization work. They're additions to a solid foundation, not substitutes for it.
How Much Can Scores Improve?
The realistic range of improvement depends on the complexity of the site and what's already been done. In our experience across 50+ Elementor optimization projects:
Sites on shared hosting with no prior optimization typically score 20-40 on mobile. After full optimization including a hosting migration, scores reach 80-94.
Sites already on decent hosting with some caching in place typically score 45-65. After targeted optimization work, they reach 85-92.
WooCommerce stores are harder. The checkout page loads significant third-party scripts (payment processors, analytics) that are outside your control and drag scores down. Realistic targets for optimised WooCommerce stores are 75-88.
The Business Case
A one-point improvement in PageSpeed doesn't mean much. A 40-point improvement does. Google's own research shows that as page load time goes from 1 second to 3 seconds, mobile bounce rate increases by 32%. Going from 1 to 5 seconds, it increases 90%. Every second of load time is costing you visitors, and visitors are costing you revenue.
The cost of professional speed optimization work — typically $1,500 to $4,000 for a full Elementor site — pays for itself within weeks for any business generating meaningful traffic. And the results don't just help PageSpeed. They improve every performance metric that matters: Core Web Vitals, bounce rate, session duration, and conversion rate.
If your Elementor site is scoring below 60 on mobile PageSpeed, it's worth taking seriously. The problem is solvable — but it requires more than a plugin install.
