To measure your landing page conversion rate success, it's important to set a benchmark, track your progress, and evaluate your results. To begin, you can use industry averages, historical data, or your own goals to set a realistic and achievable benchmark. To track your progress, monitor your landing page conversion rate over time and see how it changes in response to testing and optimization. Additionally, consider other metrics such as bounce rate, time on page, or cost per conversion for a more comprehensive picture. Finally, compare your landing page conversion rate with the benchmark to see if you have met or exceeded expectations. Analyze the impact of your landing page conversion rate on growth and profitability using a calculator or formula. For example, if your landing page conversion rate is 15%, average order value is $100, and cost per acquisition is $20, you can calculate that each conversion generates $80 of profit and 100 conversions generate $1,200 of profit.
