What are the key metrics to track for CRO in digital marketing?

Start with your conversion rate, obviously, but that’s just the beginning. Track bounce rate, time on page, and scroll depth to see engagement. Look at click-through rates on CTAs, form completion rates, cart abandonment (for e-commerce), and lead quality (for B2B). If you’re running A/B tests, keep an eye on statistical significance, lift, and confidence levels. Segmented data is even more powerful; it tells you how returning users convert vs. new ones, or which devices or channels underperform.
