It’s not like it’s a surprise as my previous wix site I worked on have slow mobile speeds too. Here is the link www.ugcnow.co (under development) I know there is so many videos and animations but the client wanted it. I’ve also checked other wix sites with no videos and it’s as slow as ours.
some elements need a bit of adjustment I can see but as for loading in fact, it is fine for me (internet speed 300MBP/S +)

@Rob hey man, do you have something to add?
Is the speed test not reliable? Client is using this as baseline for the speed.
So from my understanding of the lighthouse reports, they usually test the site under the sub-optimal speeds but most people will have access to high-speed internet speeds. A good barometer for the speed is how it works on your own device.
Hi , @bernadette
Sites can feel slow on mobile, especially when they include video, animations, and multiple sections loading at once. But it’s also true that most of the slowdown usually comes from how assets are loaded, not just the platform itself.
Here’s what actually makes the biggest difference in cases like yours:
1. Videos are the main bottleneck
Autoplay videos in hero sections block fast rendering.
Replace them with a static poster image + “play on click” (or lazy-load the video only when visible).
2. Above-the-fold simplicity matters most
Even if the full page is heavy, the first screen should be minimal.
Keep only one key animation or visual element at the top.
3. Lazy-load everything below the fold
Ensure images, galleries, and sections load only when scrolled into view
4. Reduce third-party apps and defer scripts
Every third-party script blocks the browser from rendering your page. Defer or async-load anything that isn’t critical to the first screen.
5. Optimize media files
Use compressed MP4/WebM for video and WebP for images. Oversized assets are a very common hidden issue in Wix builds.
These adjustments should give you a noticeable boost in mobile speed while keeping the design intact.
If you want to skip the manual process, a tool like Website Speedy can be used to further improve mobile performance by optimizing assets and loading behavior. It’s completely optional to use.
