Conversion Rate Optimization for Sales Funnel

Table of Contents


In this chapter, we will discuss the importance of conversion rate optimization (CRO) in the sales funnel and provide tips, examples, and strategies to improve your conversion rates. Conversion refers to a visitor on your website taking the desired action, such as signing up for an email list or making a purchase. CRO helps identify and fix any issues in your sales funnel, allowing you to generate more revenue from your advertising efforts. It also helps maximize profits, as your conversion rate directly affects your overall profitability.

1. Essential Conversion Rate Optimization Terms You Need to Know

Before diving into CRO, it’s important to understand some key terms:

  • A/B testing: Comparing two versions of a page to determine which one performs better.
  • Multivariate testing (MVT): Testing multiple variations of page elements to find the most effective combination.
  • Bounce rate: The percentage of visitors who leave your site after viewing a single page.
  • Average time on site: How long visitors spend on your site before leaving.
  • Primary conversion: The main action you want visitors to take on your site, such as adding a product to the cart.
  • Secondary conversion: The next best action a visitor can take if they’re not ready for the primary call to action.
  • Customer acquisition cost (CAC): The cost to acquire a new customer.

2. How to Conduct a Conversion Rate Optimization Audit

To improve your conversion rates, you need to conduct a thorough audit of your site and traffic sources. Here’s a step-by-step guide:

Step 1: Evaluate your business goals

Clearly define your objectives and identify the key actions you want visitors to take on your site. Install Google Analytics to measure and track your data effectively.

Step 2: Evaluate your UX

Assess the user experience of your site, considering factors like usefulness, usability, desirability, findability, accessibility, and credibility. Ensure that your site is intuitive, visually appealing, and easy to navigate.

Step 3: Evaluate your analytics

Check if your analytics setup is accurate and error-free. Identify any technical issues or incorrect settings that may affect your data collection.

Step 4: Collect qualitative data

Collect qualitative data through usability tests to understand how users interact with your site. Use tools like UserTesting to observe and gather feedback from real users. Identify areas of difficulty and friction that may hinder conversions.

3. Conversion Rate Optimization Examples (And Case Studies)

Here are two examples of companies that successfully improved their conversion rates through CRO:

Example 1: Kuna

Kuna, a home security product seller, wanted to increase sales and approached a marketing agency for a website redesign. However, the agency conducted small experiments first and found that simple changes to the homepage could significantly improve conversions. By updating the design, copy, and adding a demo video, Kuna increased sales by 89% in just three weeks. They continued to optimize their site and eventually grew revenues by 265%.

Key takeaways: Use language that resonates with your customers, create visual intrigue on your homepage, and improve navigation for a seamless shopping experience.

Example 2: Morphsuits

Morphsuits, an online retailer of full-body spandex costumes, analyzed their checkout page and found it underperforming in terms of conversions. Through A/B testing and usability tests, they discovered that a visually unappealing order review page was causing a drop in conversions. By redesigning the page with improved visuals, they boosted conversions by 37%.

Key takeaways: Analyze specific pages with low conversion rates, make simple style changes to improve visual appeal, and optimize the checkout process for a smoother user experience.


Conversion rate optimization is essential for improving your sales funnel and maximizing profits. By understanding key terms, conducting a thorough audit, and learning from successful case studies, you can make data-driven improvements to your website and increase conversion rates. Implement these strategies and continually test and optimize to achieve better results for your online business.
