Page speed refers to how quickly a web page loads and displays its content to users. It is an important factor for both user experience and search engine optimization. When a page loads quickly, visitors are more likely to stay and engage with the content, while slow-loading pages can lead to frustration and increased bounce rates. Improving page speed can involve optimizing images, reducing server response times, and minimizing the use of heavy scripts. Tools like Google PageSpeed Insights can help website owners analyze their page speed and provide suggestions for improvement, ultimately enhancing the overall performance of their site.
