Metrics to measure performance against maximizing performance.*Page ValuePages / VisitcEcommerce conversion rateBounce rate

It seems like you haven't asked a specific question. However, I can explain what the metrics you mentioned are used for in terms of measuring website performance:

1. Page Value: This is a metric used in Google Analytics. It gives you an idea of which pages on your website contribute most to your revenue.

2. Pages / Visit: This is the average number of pages a user views during a single session on your website. More pages per visit often indicates that users are highly engaged and willing to explore more of your site.

3. Ecommerce Conversion Rate: This is the percentage of your website visitors who made a purchase from your online store in a set period of time. A higher conversion rate is better, as it means more of your site’s traffic is turning into customers.

4. Bounce Rate: This is the percentage of visitors who navigate away from your website after viewing only one page. A high bounce rate often indicates that the site entrance pages aren't relevant to your visitors.

Each of these metrics can be used to measure the performance of a website and help identify areas that can be improved to maximize performance.
