Regardless of your website’s industry or audience, it is important for web pages to load quickly. In fact, research shows that a one-second delay increases the likelihood of a bounce (the visitor leaving your site) by 32 percent (1).
Increasing website performance in various ways is known as website optimization. Here are a few tips to help you improve your website’s loading speeds.
1. Optimize Images
Images are one of the largest contributors to page weight, slowing down web pages. Image optimization is the process of decreasing image file sizes without compromising quality.
Optimizing images can help shave seconds off loading times, make visitors happier, and improve conversions and revenue. It can also save on bandwidth costs and improve website performance.
2. Optimize CSS
Cascading style sheets (CSS) are the backbone of web design and have a major impact on website performance. If not optimized correctly, CSS can slow down website load times and impact visitor experience.
Inlining critical CSS can reduce file size and speed up page load. Also, use CSS sprites to combine images into one file and reduce the number of HTTP requests.
3. Optimize JS
A fast website delivers a positive user experience, which leads to higher conversion rates and brand loyalty. Learn about a wide range of website performance optimization techniques like minimizing file sizes, reducing requests, and leveraging caching and async loading.
Efficient DOM manipulation minimizes main-thread work (parsing, compiling, and network payloads). Chunking up work and avoiding frequent garbage collection pauses can keep pages from janking.
4. Optimize Database
Website performance is how fast the content on your site loads in a web browser. Faster websites lead to higher return visitors, lower bounce rates, conversions, engagement and a better user experience.
A slow website costs you money and damages your reputation. Thankfully, you can optimize your database for faster loading speeds. Start by optimizing how your server queries databases, or migrate to faster database systems.
5. Optimize CSS Animations
Web page load speed has a direct impact on user experience and is a factor in search engine optimization. Optimizing website performance can have a positive effect on both of these.
Optimizing frontend data loading speeds involves reducing latency (the time it takes for files to travel from a server to a user's browser), compressing, and lazy loading. By following these best practices, you can improve the experience of your visitors.
6. Optimize CSS Stylesheets
Many sites have multiple CSS files which have a negative impact on load time. Modern build tools and CSS pre-processors like Sass can help reduce this number by combining partials into a single file that is much smaller, more easily gzipped and cached, and easier to maintain.
Large CSS files take longer to download and parse, blocking other resources from loading. Optimizing CSS performance will speed up website rendering and improve user experience.
7. Optimize CSS Animations
The right animations can add a great deal of visual appeal to your website and enhance user experience. However, excessive web animations can lead to high loading times and impact website performance.
This is especially true for websites hosted on shared servers, where resources (RAM, disk space, and CPU time) are shared between multiple sites.
8. Optimize CSS Animations for Mobile
Website speed is one of the most important aspects to consider when designing your site. A fast-loading website leads to higher conversion rates, lower bounce rates, increased engagement and a better user experience.
9. Optimize CSS Animations for Mobile
Many websites use custom animations to create a more interesting user experience. But these animations can also slow down a website.
Web performance optimization is a complex process, but it's essential for a good online presence. Faster websites are more engaging, increase conversions, and boost search engine rankings. They also provide a better user experience for mobile users. And, last but not least, they can boost the reputation of a brand.
10. Optimize CSS Animations for Mobile
A fast website leads to more return visits, higher conversions, better SEO, and a better brand reputation. It also reduces bounce rates and improves user experience.
Web designers can optimize CSS animations by limiting transitions and transforms, using simpler animations, and ensuring that code is compatible with all browsers and devices. They can also use the will-change property to avoid animating properties that trigger reflow and repainting.
