To ensure that your YouTube videos load quickly, there are several steps you can take. First, you should compress the video file size by reducing its resolution and bitrate. This will help to reduce the amount of data being sent over the internet. Second, use a Content Delivery Network (CDN) for hosting your video files. A CDN is designed to deliver content quickly and reliably from multiple global locations, which helps to speed up delivery times. Optimize the HTML code on your website or landing page where the video is embedded. By removing unnecessary elements such as images and extra lines of code, you can make sure that the video loads faster.
