Once your landing page is published, there are a few steps you can take to test and optimize your page to increase conversions. Here are some steps you should take: 1. Define your testing goals and have a clear plan. 2. Have one well-defined metric that you are optimizing for. 3. Use a third-party A/B testing tool or one within your landing page software. 4. Change one item at a time (like a headline, image, call-to-action, or button color) so that you know exactly which variable led to the performance change. 5. View your analytics dashboard and reporting to see which landing page is converting better based on the metric you're tracking.
