Complianz’ YouTube placeholders are downloaded from youtube.com to be locally served to your website visitors in the default, and highest resolution, instead of lower and noticeable worse quality. This means on the first page load a new user will download a .jpg between 50-150kb per video before it’s cached. The upside is that videos and the connection are blocked with YouTube, improving speed, but the image still shows up as a resource, although lazy-loaded by default in most cases.
Optimize YouTube Placeholders
To mitigate this issue you can create a custom, single YouTube placeholder to be loaded that can be optimized with compression tools like Imagify, Shortpixel etc.
