Step-by-step explanation:
The best way to monitor the effectiveness of a website once it's published is to use analytics tools to track website traffic and user behavior. Analytics tools can provide valuable insights into how visitors are interacting with the website, such as the number of visitors, their geographic location, the pages they visit, and the actions they take.
In addition to analytics, it is also important to regularly test and optimize website performance. This involves conducting tests to improve aspects such as website speed, usability, and functionality. By monitoring conversion rates and goal completions, you can determine if the website is achieving the desired outcomes, such as making sales or generating leads.
