There are a few key metrics that you can use to determine whether your conversion rate optimization efforts are working. The first metric is your conversion rate. This is the percentage of visitors to your site who take the desired action, such as making a purchase or signing up for a newsletter. If your conversion rate is increasing, it means that more people are taking the desired action on your site. Another metric you can use is your click-through rate (CTR). This is the percentage of people who click on a link or ad that you’ve placed on your site. If your CTR is increasing, it means that more people are finding your links and ads relevant and are clicking on them. Finally, you can also track the number of leads or sales you’re generating from your site. If you’re noticing an increase in leads or sales, it’s a good sign that your conversion rate optimization efforts are working. To sum up, the best way to determine whether conversion rate optimization is working is to track your conversion rate, CTR, and the number of leads or sales you’re generating. If you see an increase in any of these metrics, it means that your efforts are paying off.
