Good piece, but damn I was hoping for some details on their implementation. Are the variations coming from the server, CDN/edge, or client? How does this impact SEO? Do they change the article slug if the title is a winner? How much is automated and how much is human curated? When beset with new assignments who has the time to babysit these things?

cdn; seo impact is also tested for; canonical URL doesn't change; titles are written by humans, testing is entirely automated; small parts of larger UX team just do testing so babysitting these is their job

+++ thank you! A stack to aspire to!

Is the headline testing some sort of multi-arm bandit system or a/b tests that are updated manually?

It seems like MAB would be the ideal approach for something like headlines.

How do you measure SEO impact in a title split test? Scraping SERPs or monitoring query volume real-time?
