Another major problem is too many external scripts . While scripts like trackers, ads, or social widgets can add valuable functionality, they can also slow down your site, especially when loaded from external sources. Each additional script requires an additional request to the server, which delays the overall load time.
Reasons why pages load slowly
Reasons why pages load slowly
Lack of code optimization is another cause of slow pages. Overly email list australia complex, inefficient, or unnecessary code can slow down page processing. Reusing libraries, unused CSS or JavaScript scripts, and overly complex database queries can all affect loading speeds.
Ultimately, server issues can also affect performance. Insufficient bandwidth, outdated software, poor configuration, or even the physical location of the server relative to the user can all lead to delays. Choosing the wrong hosting plan, especially in the case of cheap or shared solutions, can be a major source of performance issues.
Understanding these factors is key to improving site performance, leading to better user experience and ultimately, better business results.
How to check page loading speed, useful tools
You ask me Marcin “How to check the performance of a website”?
Page load speed is a key element of user experience ( UX ) and can have a direct impact on conversion rates and search engine positioning. With various speed testing tools, we can accurately assess how our site performs in various conditions and on various devices.
Wondering how to improve your site's loading speed? Below I've listed the 4 best tools to support this process.
Google PageSpeed Insights is a free tool from Google that analyzes your site's performance on both mobile and desktop devices. In addition to giving you an overall speed rating, it provides specific optimization suggestions to help you identify and eliminate bottlenecks.
GTmetrix is another popular tool that offers in-depth analysis of a site’s performance. It presents both PageSpeed and YSlow scores, as well as information on page load times, page size, and number of requests. Users can customize the location and browser from which the test is run, giving a more complete picture of performance.
WebPageTest is an advanced tool that allows you to test your site from different locations around the world, on different types of internet connections. It offers detailed waterfall analysis of page resource loading, which is extremely helpful in identifying performance issues.
Chrome DevTools is a set of developer tools built into the Chrome browser. The “Performance” section allows you to see exactly how a page loads in real time, identifying lag and performance issues. You can also simulate different network conditions, which is extremely valuable for optimizing for different types of connections.
Google Lighthouse is an open-source tool from Google that assesses the quality of websites across a variety of dimensions, including performance, accessibility, web application practices, and SEO. It is designed for both developers and SEO specialists to identify issues that may impact user experience. With interactive reports and actionable tips, Lighthouse offers actionable suggestions for optimizing your site. It works as a browser extension or in command-line mode, becoming an essential tool in the modern web ecosystem.

Page loading speed, optimization
How to optimize to improve page loading speed?
Page speed optimization is key to improving user experience and achieving better search engine results. There are several proven methods that can achieve significant improvements in site performance.
Compressing images and assets is one of the easiest ways to reduce the size of your page. Tools like TinyPNG or JPEG Optimizer allow you to compress images without any noticeable loss of quality. Additionally, technologies like Gzip can help compress assets like scripts and stylesheets.
Using CDN ( Content Delivery Network) involves using a global network of servers that store copies of the site's resources and deliver them to users from the location closest to their physical location. This makes the server's response time shorter and the site loads faster.
Optimizing CSS and JavaScript code involves removing unnecessary code, shortening selectors and functions, and combining multiple files into one. Tools like UglifyJS or CSSNano can help with this task by minimizing and optimizing code.
Asynchronous script loading allows scripts to load in the background, without blocking the rendering of the page. This means that the user can see and interact with the page even if some scripts are still loading.
Using browser and server caching is key to fast page loading on subsequent user visits. By storing frequently used resources in the cache, you can avoid unnecessary requests to the server and increase the speed of page display.
By implementing these techniques, you can significantly improve your page load speed, leading to better user engagement, higher conversion rates, and improved search engine visibility.
