Challenge we solve

How we solve Youtube Videos Not Lazy Loaded

In our experience, this issue occurs when embedded YouTube videos load the full YouTube iframe player immediately on page load rather than deferring it until the user scrolls to or interacts with the video, commonly from using the standard YouTube embed code as is instead of a facade pattern that loads only a static thumbnail image until clicked. The default iframe embed pulls in a significant amount of YouTube's own JavaScript and network requests regardless of whether the user ever plays the video. This adds substantial unnecessary weight to initial page load, directly hurting Largest Contentful Paint and Total Blocking Time on pages where the video isn't the primary above the fold content.

How we solve YouTube Videos Not Lazy Loaded

Why this happens (and how we fix it)

In our experience, this comes from using YouTube's standard embed code exactly as provided, which loads the full iframe player and a meaningful chunk of YouTube's own JavaScript immediately on page load, rather than implementing a facade pattern that shows only a lightweight static thumbnail until the visitor actually clicks to play. Most CMS video embed blocks are built around the standard iframe snippet by default, so the lazy loading facade has to be added deliberately rather than coming built in.

What it costs you while it goes unfixed

In our experience, the default embed pulls in substantial unnecessary network weight regardless of whether the visitor ever plays the video, adding directly to Largest Contentful Paint and Total Blocking Time on any page where it appears. On pages where the video isn't the primary above the fold content, that's dead weight loaded on every single visit for a feature most visitors never interact with.
