What tools do you use to attribute #webperf metrics to business ones? Do these tools work in China?
An agency partner recently asked - “is there was a way to track potential traffic lost on a website to build a case for improvements in markets with less visibility?”
Curious what you lot share.

Last week I gave a talk at the #PerfNow conference titled “Performance Mistakes”. I started off explaining a bit about Etsy’s blameless culture, and how it’s ok to make mistakes. Then I shared 17 common #webperf mistakes using @httparchive.org data, with examples.

Hey everyone! I ended my #perfnow talk by asking you all to consider contributing to the broader #webperf community.
And one project I called out was e18e.dev. They're trying to connect together people working on JS packages performance (example below). Please consider joining their discord!

"Always iterate". @anniesullie.bsky.social
Good advice for product management, performance experimentation and so much more.
I'm a huge proponent of the "what's the least amount of work we can do to see if we're on the right path" approach.

When not working in the web space, I’m an artist and singersongwriter under the name “Joya”.
Turns out people who are passionate about one thing tend to also be passionate in general about many, with interests. Who knew.
New to @bsky.app but recommended to give these lists a go!
