What’s interesting is that Google’s Lighthouse tool for measuring site speed pushes for “Next Gen” image formats like WebP. But I often find that WebP files are larger than jpg, too. Yet Lighthouse recommends it. And, of course it’s a great idea to follow Google’s advice since they include the Lighthouse score in their ranking algorithm.

They use some of the metrics which are provided in Lighthouse (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift) all play a role in ranking, but the score itself is meaningless.
- hoten 6y agoYou're both wrong, but you're only slightly wrong. It's been announced that those metrics will contribute to ranking in the bear future. Search for Core Web Vitals.
- gsnedders 6y agoYou are, of course, technically correct, which is the best type of correct. There's been some level of performance weighting for a while (but only very slight and mobile-only), but I don't actually know what metric they were using for that (this was from ~2018, before any of those metrics landed in Blink).
- 72deluxe 6y agoThe irony is that the Lighthouse site itself scores really badly! Can you accept its advice?
- innocenat 6y agoIdk. I optimized the end-user facing part of my website heavily, while the backend part (which is used only by a few people), I don't really care. I didn't even minify the JS.
