Use a Content Delivery Network (CDN) to reduce

[samiaseo222]

The browser must receive the first byte of the initial HTML document response before loading other resources. This time is called Time to First Byte (TTFB) , and the faster it happens, the sooner other processes can begin. To minimize TTFB, serve content from a location close to users and use caching for frequently requested content. According to Google, the best way to achieve both is to use a content delivery network (CDN).

Cumulative Layout Shift (CLS) Optimization
Cumulative Layout Shift (CLS) is a metric used lebanon phone number data to assess how stable a website's visual layout is. According to Google, approximately 25% of websites do not meet the recommended standard for this metric. These are Google's top recommendations for improving CLS.

Setting explicit sizes for content on a page
Layout shifts can occur when content on a web page changes its position after it has finished loading. To avoid this, it is important to reserve as much space as possible in advance. One common cause of layout shifts is undersized images, which can be addressed by explicitly setting the width and height attributes or equivalent CSS properties.

Images aren't the only factor that can cause a web page layout to shift . Other content, such as third-party ads or embedded videos that load later, can also contribute to CLS. One way to address this issue is to use the aspect-ratio property in CSS . This property is relatively new and allows developers to set the aspect ratio for images and non-image elements.
