3、Mobilefriendliness: With most users accessing websites on mobile devices, page speed is crucial for a smooth mobile experience.

Factors affecting page speed

1、Page size: Larger pages take longer to load.
2、Number of requests: More requests to the server can slow down page loading.
3、Server response time: The time it takes for the server to respond to a request.
4、Browser rendering: The time it takes for the browser to render the page.
5、Network latency: The time it takes for data to travel from the server to the user's browser.

Optimization techniques

1、Minimize HTTP requests:
