Pages per Session

This KPI tells you how many pages the average user views during a single session on your website. A higher number indicates that users find your content engaging and valuable.

To calculate: Total pageviews / Number of sessions

Conversion Rate

Conversion rate is perhaps the most critical KPI, measuring the percentage of visitors who complete a desired action on your website, such as making a purchase, filling out a form, or signing up for a newsletter.

To calculate: (Number of conversions / Total number of visitors) x 100

Technical Performance KPIs

Technical performance KPIs ensure that your website functions smoothly and provides a positive user experience.

Page load time is a vital KPI, as slow-loading pages can frustrate users and negatively impact your search engine rankings.

Mobile Responsiveness

With mobile traffic accounting for more than half of all web traffic, it's crucial to ensure that your website is mobile-friendly. This KPI measures the percentage of mobile users who have a positive experience on your website.

To calculate: (Number of mobile users with a positive experience / Total number of mobile users) x 100

Broken Links

Broken links can frustrate users and hurt your website's SEO. Regularly monitoring and fixing broken links helps maintain a positive user experience and preserves your website's authority.

To track: Use tools like BrokenLinkCheck or DeadLinkChecker to scan your website for broken links.

Regularly reviewing and optimizing these KPIs will help you create a more engaging, user-friendly, and ultimately successful website. Keep in mind that KPIs are not one-size-fits-all, so always tailor your tracking to align with your unique business goals.
