Which technique is commonly used to improve website loading speed?

Compressing images and files is a widely recognized technique for improving website loading speed. When images and files are large, they require more time to download, leading to slower loading speeds. By compressing these assets, the file sizes are reduced without significantly losing quality. This makes the website load faster, enhancing the user experience and potentially improving search engine rankings since faster websites tend to perform better in search results.

While other options may seem logical at first glance, they typically do not contribute positively to load times. For example, adding more embedded videos can slow down loading speeds because videos often require significant bandwidth to stream. Incorporating more pop-up ads would likely add additional layers of content that users must wait for to load, which can also detract from speed. Reducing text content might seem like a solution, but if not done carefully, it can lead to a site that lacks meaningful information, thus impacting both user engagement and SEO. Therefore, compressing images and files stands out as an effective strategy for enhancing website performance.
