Site Performance: How Wix Improves a Site's Loading Time
Having a fast loading time ensures a smooth and pleasant experience for site visitors. We're always striving to optimize the performance of Wix sites, and have implemented ways to improve loading time.
Automatic image optimization
Images can add life and context to a site. Whether you're using them to display photography, information, or for decoration, it's important that their quality isn't compromised.
When you upload an image to a Wix site, we resize the image for optimal quality and site loading time. Images less than 25MB are automatically compressed, so you don't need to change anything before you upload.
Content delivery network (CDN)
To ensure optimal loading speed, Wix uses CDN - a system of global cache services and proxy servers. CDN works by delivering site content to visitors from the server geographically closest to them.
CDN acts as the middleman between Wix servers and site visitors, reducing latency and site loading time.
Defense against distributed denial-of-service (DDoS) attacks
Whether your site has a Wix domain or is connected to the name servers, we minimize the effect of DDoS attacks against the site.
DDoS attacks overload the servers, and cause them to react slowly or not at all. Wix has a set infrastructure that can lessen the results of these attacks, and may prevent a site's loading time from being severely impacted.
Lazy loading images
High resolution images can significantly impact a site's loading time. To ensure a better visitor experience without compromising content, Wix uses a technique called lazy loading.
This technique boosts loading time by replacing high-resolution images with low-resolution versions. The low-resolution placeholders load instantly (even on slower networks), while the high-resolution content loads in the background. Once loaded, the high-resolution images automatically replace the placeholders.
FAQs
Click a question below to learn more.
What should I do if my Wix site is inaccessible in certain countries?
If your site is inaccessible in specific regions, it may be due to local ISP restrictions. Advise users to contact their ISP and provide any relevant information about the block.
Tip: Ensure your site's domain and hosting comply with international regulations.
How can I identify which elements are slowing down my website?
Use Wix's Site Speed dashboard or Google PageSpeed Insights to analyze performance metrics. Focus on:
Large images or videos.
Excessive animations or third-party apps.
Inefficient custom code.
Tip: Regularly review your site for unused media or elements and remove them.
Why are my customers experiencing issues with my online store checkout process?
Checkout issues may arise from:
Session timeouts or browser caching.
Overlapping elements in the design.
Third-party app conflicts.
To resolve this:
Test the checkout process on different devices and browsers.
Clear the browser's cache and cookies.
Ensure that all payment methods are connected correctly.
Tip: Use Wix Analytics to monitor customer behavior during checkout and identify potential issues.
Why does my Wix site show a blank screen before loading content?
A blank screen may occur due to:
Slow loading of large elements, like images or videos.
Browser caching issues.
Network connection problems.
To address this:
Optimize images and videos for faster loading.
Enable caching to improve repeat visits.
Test your site on different devices and internet connections.
Tip: Use Wix's Performance Dashboard to identify bottlenecks.
Can I disable lazy loading?
No. Lazy loading is a built-in Wix feature designed to protect your site's overall speed. It works by displaying a low-resolution version of an image while the high-resolution version loads in the background, ensuring visitors see content immediately rather than a blank space.
Because lazy loading is core to how Wix optimizes site performance, it can't be turned off. If this is something you'd like to see in the future, you can vote for this feature.
