Sales metrics are key indicators that measure sales performance and can include closing ratios, conversion rates, cost per lead, return on investment (ROI), and customer lifetime value (LTV). To improve your sales strategies using these metrics, you should first list what you are currently measuring. Then, identify an additional area you can measure, such as data from your website or the value of different customer segments. Over time, track and review your measurements, which should facilitate your marketing decisions. Involve your team in this process so that the metrics are adopted more quickly into your standard operating procedures. Finally, repeat this process, adding metrics one by one and taking action based on your findings.
