Frequently Asked Questions
What are funnel metrics?
Funnel metrics are measurements that track how users move through each stage of the marketing and sales funnel, from visitors to leads and ultimately to customers. They help identify drop-off points and optimization opportunities.
How do you calculate funnel conversion rates?
Funnel conversion rates are calculated by dividing the number of users at one stage by the number from the previous stage, then multiplying by 100 to get a percentage.
What is a good visitor-to-lead conversion rate?
A typical visitor-to-lead conversion rate for B2B websites ranges between 2% and 5%, although benchmarks vary by industry, traffic source, and offer.
What is the difference between CPL and CPA?
Cost Per Lead (CPL) measures how much you spend to generate a lead, while Cost Per Acquisition (CPA) measures the cost to acquire a paying customer. CPA provides a clearer picture of true customer acquisition costs.
Why is it important to track both CPL and CPA?
Tracking both CPL and CPA helps businesses balance lead volume with lead quality, optimize marketing spend, and ensure acquisition costs remain profitable compared to Customer Lifetime Value (CLV).
How can I improve my funnel metrics?
You can improve funnel metrics by optimizing landing pages, improving traffic quality, refining targeting, nurturing leads with relevant content, and continuously testing and measuring performance.
