A very interesting rundown of some common performance checks and techniques that Ben went through to boost their lighthouse score from <50 to >95! I was particularly interested that font subsetting didn't have a huge impact on the score, despite reducing the download size by 44%, but that's still a significant saving and well worth it in my book. Equally, the impact of the native YouTube embed was slightly terrifying, and I'll definitely consider lite-youtube-embed for any future projects that need similar integration:
This move away from YouTube's proprietary embeds ended up being a huge lift for my performance, bringing my homepage's Lighthouse performance score from a poor 48 up to a respectable 81 out of 100. I'd heard just how devastating third-party scripts and trackers can be for a site's performance, and this change really hammered that home for me.
