Website performance improvement is about making a web page as fast as possible to improve the user experience and increase conversions. As mobile internet usage overtook desktop internet use in 2016, slow websites are more and more frustrating for users. Slow loading times can also negatively impact search engine rankings and lose you traffic and potential leads.

TTFB, FCP and LCP are all important Website performance improvement speed metrics that measure the amount of time it takes for a browser to download and render a webpage. It’s recommended to keep these under two seconds for a good user experience.

Many of these performance metrics are influenced by the number of HTTP requests that are made to load a webpage. Each request results in a round trip to and from the server hosting each resource, which can add up. To minimize HTTP requests, minify your HTML files, CSS and JavaScript through tools like cssnano and UglifyJS to compress code, remove unnecessary comments, and combine files. Use responsive images and browser caching to serve different image sizes based on screen size.

Page load times are further impacted by server response time and the quality of your network connection. Optimize database queries, minimize scripting overhead and minimize the number of active requests to reduce server load time. A content distribution network (CDN) can help improve website speed by storing copies of your website’s assets on servers closer to users to minimize network latency. This can be especially helpful for global users.
