What metrics should I track when working with a CRO freelancer?

Start with conversion rate, but also track supporting metrics like bounce rate, average order value, time on site, and form completion rate. Funnel drop-off points help show where people are getting stuck. If you’re running experiments, measure performance for each variant. Also monitor changes in page speed and mobile usability, especially if design changes are involved. Set definite goals up front so both you and the freelancer know which metrics matter most.
