If your Elementor site scores 90 on desktop and 40 on mobile, nothing is broken. That gap is normal, and a low Elementor mobile PageSpeed score usually comes down to a short list of causes.

Mobile tests are harsh on purpose. PageSpeed Insights loads your page on a simulated mid-range phone, over a throttled connection and with the CPU slowed down about four times. A page that feels instant on your laptop can take several seconds under those conditions. Page builders feel this more than most sites, because they ship more markup, CSS and JavaScript than a hand-coded page.
Here is what I check first when an Elementor site is slow on mobile, in the order that usually pays off.
What a mobile PageSpeed test simulates
1. Start with the hero image
On most Elementor pages, the largest thing on screen is the hero image or a background image in the first section. That is your Largest Contentful Paint (LCP) element, and it decides whether the page feels fast.
- Do not lazy-load it. Lazy loading is for images below the fold. Applying it to the first image delays the one thing the visitor is waiting for.
- Right-size it. A 2,400 px photo does not need to reach a phone that is 390 px wide. Upload a sensible size and let WordPress serve the responsive versions.
- Compress it and use WebP. Most hero photos can lose more than half their weight with no visible difference.
- Prefer an Image widget over a CSS background when the design allows it. Browsers find an image tag early, while a CSS background is only discovered after the stylesheet has loaded.
2. Check Elementor’s own performance settings
Elementor has improved its output a lot, but some options depend on your version, and a site built a few years ago may not be using them. In Elementor’s settings, under Features or Experiments (the name changes between releases), look for options such as improved asset loading, improved CSS loading, inline font icons, optimized DOM output and lazy loading for background images. Defaults vary, so check what your version offers and test the site after each change.
Also think about your layout method. Flexbox Containers generally produce fewer nested wrappers than the older Section and Column structure, which keeps the page smaller and easier for a phone to handle.
3. Trim the add-ons you barely use
Add-on packs can load scripts and styles for widgets you never placed. Open the add-on settings and switch off every widget and extension you are not using. It is a five minute job, and it often removes several files from every page.
The same question applies to sliders, popups and animation effects: does this earn its weight on mobile? A strong image with a clear button often performs as well as a slider, at a fraction of the cost.
4. Fonts and icons
- Stick to two font families and only the weights you really use.
- Self-host your Google Fonts and set font-display to swap, so text shows immediately instead of waiting.
- Remove icon libraries you are not using. Loading a full icon set for three icons is common.
5. Background videos
An autoplay background video in the hero is one of the heaviest things you can put on a mobile page. If the design needs it, use Elementor’s responsive visibility to hide the video on phones and show a compressed static image instead.
6. Caching, compression and JavaScript
A good page cache with Gzip or Brotli compression is the baseline. Minifying CSS and JavaScript helps too. Options like delay JavaScript until interaction can lift a score quickly, but they can also break sliders, menus and forms, so turn them on one at a time and test on a real phone, not just in the browser.
Caching works best on a solid server
Page caching and compression help most when the server underneath is reliable. Hostinger’s hosting plans run on LiteSpeed server technology and supports the LiteSpeed Cache plugin for WordPress.

Layout shifts and slow taps
Two quieter problems show up in Core Web Vitals.
- CLS (layout shift): set width and height on images, reserve space for sliders, popups and cookie banners, and avoid banners that appear late above the content.
- INP (responsiveness): chat widgets, trackers and heatmaps are frequent culprits. Load them later, or remove the ones nobody looks at.
A quick diagnosis table
| What you see | Likely cause | What to do |
|---|---|---|
| Fine on desktop, poor on mobile | Heavy hero image, large page structure, third-party scripts | Optimize the hero, simplify the layout, defer scripts |
| Warnings about unused CSS and JavaScript | Add-on widgets loading on every page | Switch off unused widgets and modules |
| Content jumps while loading | Images without dimensions, late banners | Set image dimensions, reserve space for banners |
| Page feels laggy when tapping | Heavy JavaScript, chat or tracking tools | Remove or delay third-party scripts |
| Slow first paint | No page cache, no compression | Enable caching and Gzip or Brotli |
What to expect from Elementor mobile PageSpeed fixes
A score of 100 is rarely the right goal for an Elementor site with a rich design. Your hosting (for example, WordPress hosting for Elementor sites), add-ons and content all set a ceiling. A better target is a passing Core Web Vitals assessment and a mobile score that moves clearly in the right direction while the design stays exactly as it is.
How to test your changes
Run PageSpeed Insights on the mobile tab at least three times, because scores vary between runs. Look at the field data (real visitors) first if it exists, then use the lab data to see what is causing the problem. Keep a backup before you change anything, and save a before and after report so you know what actually helped.

Will optimization change how my Elementor design looks?
It should not. The work targets how the page loads, not how it looks. Your layout, widgets and styling stay the same, and anything that cannot be kept safely should be flagged rather than removed.
Can anyone guarantee a mobile PageSpeed score?
No. Scores depend on hosting, add-ons, theme and content. A fair promise is the best realistic improvement and a report that shows the difference.
Do I need to give access to my site?
Usually a WordPress admin login is enough. Hosting or cPanel access is sometimes needed for caching or server settings.
