What metrics do you actually rely on in your eCommerce business?

Hey everyone — I’m new here and trying to learn from people actually running eCommerce stores or working in growth/ops.

Out of curiosity:

• Which 2–3 metrics do you check most often?

• Are there any dashboards or tools you actually trust daily?

• What data do you wish you had but don’t currently have?

I’ve been speaking with a few people in eCommerce and noticed everyone tracks things a bit differently, so I’m trying to understand what “real usage” looks like vs what tools assume.

Would appreciate any insights — even short answers
