The question now is how to optimize the website’s performance? Here are the top 10 web performance optimization techniques that you should know and put into practice. 

Top 10 Web Performance Optimization Techniques

• Image optimization: Images put life into your website, however, they can also spoil things. Images take up a significant portion of web pages and can increase the website’s loading time. Compression of images is one of the ways to optimize web performance.  With image compression, you can maintain a fine balance of having those images without affecting the website’s performance. 

• Smartphone-friendly website: Mobile devices like smartphones and tablets drive over 60% of traffic to websites. Therefore, it’s important to optimize the performance of your website as per the needs of smartphone users. The website should be responsive enough to fit the size of the mobile screen. Test the website design for various screen sizes and adjust the responsiveness accordingly. 

• Host it well: Hosting services matter a lot when we talk of web optimization.  A hosting service provider may offer a cheaper plan, but it can turn expensive for you later on. A slow host server can significantly increase the loading time of your website. Opt for quality service providers like AWS or Hostinger.

• HTTP request reduction: The HTTP requests are used to load the content on the website by the search engine. Each of these requests takes time to build a connection with the server. Thus, the more HTTP requests more would be the loading time of the website will be. Further, too many requests can get stuck in the queue and even get blocked. Cutting unnecessary elements and content can help.

• SEO Optimization: Search Engine Optimization (SEO) is the key to ranking on top in search results. This involves both on-page and off-page SEO.

• On-page SEO:  This involves improving the quality of content on the website. Keyword research, inter-linking, content optimization, mobile-responsive web pages, etc, are some of the things that are done as a part of the on-page SEO.

• Off-page SEO: Off-page SEO is concerned with things outside the website. It involves creating credible backlinks, social media engagement, guest blogging, and user engagement via media content sharing. Performance marketing, collaboration, link sharing, etc are other ways to get the off-page SEO right.

• Technical SEO: As the name suggests, this part of SEO focuses on technical details. Technical aspects like the website’s architecture and design, the URL, and the backend of the website. There is a lot at the backend of the website, like its front end. Technical SEO is all about getting that backend right. 

• Light Theme: Opt for a light-themed website as you get it designed. Heavy themes with high-end features can put a lot of load on servers. Which means the loading time would be high and the website would load slowly. Users would not like to wait long, and even if you have chosen an impressive high-end theme, the visitor would not be there to see it.

• Browser Caching: Make sure that browser caching is enabled for your website. Caching makes sure that certain things, like the images, CSS, and JavaScript, get saved on the user’s device. This means that next time when they load the website, these things will not be loaded again. Browser Caching thus optimizes a website by reducing the load time. 

• Utilize the CDN: Content Delivery Network (CDN) is a technology that fetches the content from a server closer to the user. This helps in loading the website faster. When a user clicks on the website CDN makes sure that it fetches the content from a server that is geographically closest to the user’s location. 

• AMP pages for mobile: AMP, or the Accelerated Mobile Page, enhances the user experience of a website on mobile. Since a major chunk of traffic is driven by smartphones and tablets, AMP can help in rapid website loading, making the user experience smooth. Being a Google-designed framework, AMP also helps with SEO.        

• Performance Tracking:   Tracking the website’s performance regularly is one of the most useful web performance optimization techniques that one can implement.  This involves observing the change in traffic as you adopt the techniques that are listed above. Checking the bounce rate, looking for broken links, and fixing them. Taking a check of loading time across different screen sizes. 

Conclusion

Web performance optimization is key for growing a business online. The web performance optimization techniques that we discussed, if put into practice, can deliver the desired results. Careful implementation of these optimization techniques, backed by regular follow-ups and course correction, is the way.
