The final step is to run and analyze the experiment to compare the performance of your value propositions. You can run the experiment for as long as you need, depending on your budget, traffic, and confidence level. However, a good rule of thumb is to run the experiment for at least two weeks, or until you have at least 100 conversions per landing page version. This will help you avoid statistical errors and anomalies, and ensure that your results are reliable and valid. To analyze the experiment, you need to go to the Google Ads interface, and select the campaigns option from the left menu. Then, you need to select the campaign that you created for your landing pages, and click on the segments option from the top menu. From there, you can choose the landing page option, and see the data for each landing page version, such as impressions, clicks, conversions, and cost per conversion. You can also go to the Google Analytics interface, and select the conversions option from the left menu. Then, you can select the goals option, and choose the goal that you created for your landing pages. From there, you can see the data for each landing page version, such as goal completions, goal value, and goal conversion rate. By comparing the data from both sources, you can determine which value proposition performs better, and use it to optimize your landing page and lead generation.
