Key Performance Indicators (KPIs) to Track After Launching a Website: Your Performance Dashboard

Measure what matters to drive your site and boost your results.

Launching a website is a good start—but it's not enough. To truly benefit from it, you need to measure the right metrics . KPIs (Key Performance Indicators) provide concrete benchmarks to understand what's working, what's not, and where to focus your efforts.
Whether it's a showcase site, an e-commerce site or a B2B site, these indicators are key to effectively managing your digital strategy.

1️⃣ Why track KPIs after going live?

Tracking your KPIs allows you to:

• Verify that the site is technically functional and generates traffic.
• Understanding visitor behavior (navigation, engagement, abandonment).
• Measure conversions and return on investment (ROI).
• Identify areas for improvement to optimize user experience and performance.
• Monitor developments over time and adjust your strategy.

Without this data, you navigate blindly — with it, you pilot with precision.

2️⃣ The basic KPIs to monitor

📈 Traffic & audience

• Visits / Sessions : total number of visits over a period.
• Unique visitors : number of distinct internet users.
• Page views / session : average number of pages viewed per visit — useful for measuring overall interest.
• Traffic sources (organic, direct, social, etc.): to identify where your visitors come from.

⏱️ User engagement & behavior

• Bounce rate : the percentage of visitors who leave the site after a single page — a good indicator of content relevance and UX.
• Average session duration / Average time per page : indicates whether visitors explore your site or leave quickly.
• Entry/exit pages : identify the pages that attract or lose your visitors.

3️⃣ conversion & business KPIs

💡 Conversions & Goals

• Conversion rate : percentage of visitors who complete a key action (purchase, registration, quote request, etc.).
• Micro-conversions : intermediate actions (clicks on CTA, adding to cart, filling out form…) that show interest before the final action.

🛒 For an e-commerce website / online sales

• Average basket size : average order value, a key indicator of customer value.
• Shopping cart abandonment rate : useful for identifying payment barriers or UX issues.
• Repetition / loyalty (recurring customers, return rate): to measure loyalty and recurrence.

4️⃣ Technical & Site Performance KPIs

• Page load time / Page performance (Core Web Vitals: LCP, CLS, FID…) : speed and stability are crucial for user experience and SEO.
• Uptime : a down site means lost sales — monitor server stability.
• Error rate, HTTP errors, server time : to detect technical problems quickly.

5️⃣ How to organize all of this: create a high-performing dashboard 🧮

1. Choose 8 to 12 KPIs according to your objectives (traffic, conversion, performance).
2. Configure your analytics tools: Google Analytics, Matomo, or other.
3. Follow regularly (weekly / monthly) and compare the periods.
4. Analyze the trends, not just the isolated figures.
5. Adjust your actions: UX, SEO, content, technical aspects…

A clear dashboard = faster decisions, continuous optimization, controlled growth.
