Page speed is the amount of time it takes for your website’s content to load in a viewer’s browser. A slow-loading website can lead to a frustrating experience and increased bounce rate. There are several ways to improve your website’s loading speed. Some of the most effective techniques include minification, a content distribution network, and lazy loading.
1. Optimize Images
Image optimization is a huge part of web page performance, and it can have a big impact on SEO. However, there is a fine line between optimizing images for performance and sacrificing image quality to do so. The key is to find that balance.
One way to do this is by resizing your images for the web to reduce their file size without changing how they appear on-screen. This can be done manually or with an image optimization tool, such as TinyPNG or ImageOptim.
Another way to optimize your images is by using compression to reduce the number of pixels and kilobytes in an image. This can be done with either lossless or lossy compression. The key is to test to find the best setting for your needs.
Finally, you can use a CDN to accelerate image load speeds, or you can implement lazy loading, which loads images only when they are needed. This can be done with a plugin or by manually writing code using JavaScript and HTML.
2. Use a CDN
Using a CDN, or content delivery network, can significantly improve website load speed. CDNs store copies of your web content on multiple servers around the world. When a visitor visits your site, the closest server will deliver the cached content. This reduces latency and can significantly improve your webpage’s load time.
When a page loads, the browser makes several HTTP requests for various assets on the page. These requests can slow down page load time if the assets are large in size, especially images and video files. A good practice is to optimize these files to minimize their file sizes without sacrificing image quality.
Using a CDN can also speed up loading times for your website by reducing the number of requests made to the origin server. Depending on your hosting solution, CDNs can also help reduce server response time by using GZIP compression and optimizing CSS, JavaScript, and HTML. This can significantly improve your PageSpeed Insights score. However, using a CDN can increase your bandwidth usage, so it’s important to monitor your bandwidth and manage your costs effectively.
3. Optimize CSS
CSS is one of the most important aspects of website design, but it can also be slow to load and parse. Fortunately, there are several ways to optimize CSS.
First, minify CSS by removing unnecessary things like characters, whitespaces, and comments. This reduces the size of your code, which allows web servers to process it faster. You can do this manually, or use tools like CSSNano and UglifyJS.
Second, inline your CSS where possible. This can improve performance by reducing the number of HTTP requests, especially those made by mobile users. This will make your pages more responsive and increase user satisfaction.
Third, use lazy loading and embedding to avoid overly burdening your page with CSS. When a browser encounters a link> tag that contains an external CSS file, it halts HTML parsing to download and parse the file. This can significantly delay the rendering of your page. Lazy loading and inlining allow the critical CSS for above-the-fold content to be downloaded asynchronously without blocking render, which can substantially speed up page load times.
4. Use Lazy Loading
Lazy loading improves page load speed by deferring the download of images and other media until they’re close to being visible in the viewport. This reduces the initial number of file requests, which can have a significant impact on performance, particularly for mobile users.
Important components, like search bars and visible product listings, are loaded immediately. Non-essential elements, including lower-priority filters and more product recommendations, are postponed until they’re needed, resulting in a smooth browsing experience without unnecessary lags.
When used with a CDN, lazy loading can also reduce bandwidth usage by only downloading files as they’re needed. This can have a positive impact on user experience and lower data bills for visitors with limited data plans. Lazy loading is easy to implement using the loading> attribute in HTML, which allows developers to control when an image or other media is loaded by setting a src value for them.
For example, ad units can be lazy-loaded to ensure they are only displayed when the viewer is likely to see them. This improves their chances of being viewable and helps websites meet their ad-buying partners’ viewability requirements.
5. Optimize PHP
Using opcode caching and other optimization tools can significantly improve PHP performance. These tools cache compiled code and run it on subsequent requests, eliminating the need to recompile and reduce server load. They also reduce execution time by avoiding redundant computations and reducing memory usage.
Profiling and debugging with tools like Blackfire, Tideways, and Xdebug can help identify bottlenecks. Removing unnecessary functions, limiting the use of global variables, and following DRY (Don’t Repeat Yourself) principles can also make your code faster.
The speed of your web pages is more important than ever. People have short attention spans and will leave a site that takes too long to load, especially on mobile devices. By improving your website’s loading times, you can give users a better experience and increase conversions.
Using a CDN can also significantly reduce your site’s loading times by caching files on servers that are closer to your visitors. This can drastically reduce your page’s load time and save you money on bandwidth costs. This is especially true for sites with lots of images.
