I was at a Google sponsored hackaton focusing around page speed. They were pushing AMP. What I feel was completely missing at the time was data, testing results and case studies showing where it has improved a business ROI. They have some published now but it’s really so high level that you can’t conclude your business will get similar results. Some measure click through rate, others conversion rate or bounce rate. It’s not like for like. I feel like the data was deliberately vague. I work in ecommerce and need to know this improves conversion rate and average order value. That’s what drives revenue and profitability.
