YouTube Video Lazyloading Tool

Do you have a YouTube video that's slowing down your speed or hurting your performance and rankings? We created this tool so that you can easily paste in any YouTube video and it will convert the embed code to be lazy-loaded automatically.

Does this work on multiple YouTube videos on the same page?

Yes, this will handle as many YouTube videos as you'd like on a single page. However, after you've added the first lazy-loaded video, make sure that the checkbox is selected in the form above for all subsequent videos.

Part of the lazy-loading logic only needs to be added once, so all additional videos on the same page should have this checkbox selected before generating your optimized code. If you're using this on your site often, you may want to offload the JavaScript portion (wrapped in script tags) to your website's footer so you don't have to insert it into the content itself. Though, this step is optional.

Do YouTube videos slow my site down?

Yes, embedding YouTube videos directly into your webpage can indeed slow your site down. This is because every YouTube video on a page requires a significant amount of data to be loaded. The embedded video player, thumbnail, and scripts for functionality all consume resources. If your website has multiple YouTube videos embedded, the loading time can significantly increase, potentially leading to a slow and frustrating user experience.

Why do YouTube videos hurt PageSpeed scores?

YouTube videos can hurt your PageSpeed scores for a couple of reasons. Firstly, the YouTube embed code calls several resources, including an iframe player and additional JavaScript. Secondly, even if a visitor doesn't play the video, these resources are still loaded with the rest of the page content. This can result in a higher time to interactive, slower loading speeds, and a lower PageSpeed score as a result.

Is lazyloading a safe and effective practice?

Yes. Lazy loading is not only safe but also highly recommended for improving page loading speeds. By using lazy loading, you ensure that only the necessary content is loaded when a page is first accessed, with additional content (like YouTube videos) loaded only when needed. This reduces initial load times, conserves data usage for users, and ultimately provides a smoother and faster browsing experience. As long as it's implemented correctly, lazy loading should not cause any issues with your site's functionality.

How does this tool work?

This tool utilizes the concept of lazy loading for YouTube videos. Instead of loading the entire video and its associated resources when a page is opened, it initially loads only a placeholder image for the video. This significantly reduces the initial load on the page. Then, when a user interaction is detected, such as scrolling, the tool starts loading the heavier YouTube assets and code in the background. This means that by the time the user scrolls to the video, it's ready to play. From the user's perspective, this process is seamless, especially if the YouTube video is placed below the fold on the page. This strategy significantly improves page load speed without compromising the user experience.
