CRO Benchmark: Do's and Don'ts for Ecommerce Conversion Optimization

Is your eCommerce store converting visitors into customers? Sound familiar? Many businesses struggle to optimize their websites for maximum conversion rates. In fact, approximately 70% of online shopping carts are abandoned before checkout Baymard Institute. This guide will delve into the do's and don'ts of conversion rate optimization (CRO), specifically focusing on how CRO Benchmark can help you identify and fix conversion leaks in your eCommerce store.

Setting Expectations: Why CRO Matters

Conversion Rate Optimization is the systematic process of improving your website to increase the percentage of visitors who take a desired action – like making a purchase, filling out a form, or clicking a button. Effective CRO can lead to significant revenue increases without necessarily increasing your traffic. It's about making the most of the traffic you already have.

"CRO is not about guessing; it's about understanding your customers and optimizing their experience based on data." - Tweet from r/cro

Before we get started, consider these stats:

  • 74% of users are likely to return to a website if it is optimized for mobile.
  • Businesses that use CRO see a 40% increase in leads.
  • Companies that optimize their conversion rates see a 20% increase in sales.

Let's get started!

Understand Your Customer's Journey

Map out the entire customer journey, from initial landing to final purchase. Identify all the touchpoints and potential friction points.

Don't assume you know your customer. Rely on data, not assumptions.

Understanding your customer's journey is the foundation of any successful CRO strategy. This means mapping out the path a customer takes from the moment they land on your website to the point they complete a purchase. Consider:

  • Awareness: How did they find your site?
  • Consideration: What are they looking at? What information are they seeking?
  • Decision: What are the key factors influencing their purchase?
  • Action: What steps do they take to complete the transaction?

By understanding this journey, you can identify the weak links and areas where customers are dropping off. Use analytics tools to track user behavior, such as heatmaps and session recordings. This will provide valuable insights into where users are struggling, what they're clicking on, and what content they're engaging with.

Example: An eCommerce store selling clothing noticed a high bounce rate on its product pages. After analyzing user behavior, they discovered that the product images were too small and lacked zoom functionality. By implementing larger, zoomable images, they significantly reduced bounce rates and increased conversions.

Mobile Optimization Matters

Make sure your website is fully responsive and optimized for mobile devices.

Neglecting the mobile experience can kill your conversion rates. Mobile traffic is growing rapidly, and a poor mobile experience can drive customers away. Ensure that your website is responsive, meaning it adapts to different screen sizes. Test your site on various devices to ensure that it displays correctly and functions smoothly. Consider:

  • Fast Loading Times: Mobile users have less patience.
  • Easy Navigation: Menus and buttons should be easily accessible on smaller screens.
  • Clear Call-to-Actions (CTAs): CTAs should be prominent and tap-friendly.

“Mobile optimization isn’t just about making your site look good on a phone; it’s about providing a seamless and intuitive experience.” - Reddit post from r/DigitalMarketing r/DigitalMarketing

A/B Test Everything

Implement A/B testing to compare different versions of your website elements.

Don't make changes based on gut feelings. A/B testing provides data-driven insights.

A/B testing, also known as split testing, is a crucial part of CRO. It involves creating two versions of a webpage element (e.g., a headline, button, or image) and showing them to different segments of your audience. By analyzing the results, you can determine which version performs better, leading to higher conversion rates. Key elements to test include:

  • Headlines: Experiment with different messaging to see what resonates most with your audience.
  • CTAs: Test different button colors, text, and placement.
  • Images: Test different product photos, lifestyle images, or videos.
  • Forms: Test different form layouts and fields.

Example: An eCommerce store selling electronics tested two different versions of their product page. One version had a prominent "Add to Cart" button, while the other had a button that said, "Buy Now." The "Buy Now" button resulted in a 15% increase in conversions. A/B testing is a data-driven process. You must have enough traffic to achieve statistically significant results.

Page Speed Is Critical

Optimize your website for fast loading speeds.

Slow loading times frustrate your users. Page speed impacts both user experience and search engine rankings.

Page speed is a critical factor in CRO. Slow loading times can lead to high bounce rates, frustrated users, and lost sales. Google has made page speed a ranking factor, so optimizing your site will improve your SEO and conversion rates. Here's how to improve your page speed:

  • Optimize Images: Compress images without sacrificing quality.
  • Use Browser Caching: Enable caching to store website resources on the user's device.
  • Minimize HTTP Requests: Reduce the number of files your website needs to load.
  • Use a Content Delivery Network (CDN): Distribute your content across multiple servers.

“Page speed is a critical factor. If your site takes too long to load, you’ll lose customers.” - Reddit post from r/SEO r/SEO

Build Trust and Credibility

Display trust signals prominently on your website.

You need to earn visitors' trust. Customers are hesitant to share their personal and financial information with websites they don't trust. Here's how to build trust:

  • Display Security Badges: Show SSL certificates and payment gateway logos.
  • Include Customer Reviews and Testimonials: Social proof is powerful.
  • Offer a Clear Return Policy: Make it easy for customers to return items if needed.
  • Provide Contact Information: Make it easy for customers to reach you.
User Experience (UX) Matters

Focus on creating a seamless and intuitive user experience.

A poor user experience will drive customers away. A well-designed website will guide visitors through the conversion process effortlessly. Consider:

  • Intuitive Navigation: Make it easy for users to find what they're looking for.
  • Clear and Concise Content: Use simple language and avoid jargon.
  • Visually Appealing Design: Create a clean and modern design.
  • Mobile-First Approach: Ensure the site is responsive and optimized for mobile.
Analyze Your Data

Track and analyze your data regularly.

Data provides the answers. You need to track key metrics and analyze the results to understand what's working and what's not. Use analytics tools like Google Analytics to track metrics such as:

  • Conversion Rate: The percentage of visitors who complete a desired action.
  • Bounce Rate: The percentage of visitors who leave your site after viewing only one page.
  • Click-Through Rate (CTR): The percentage of users who click on a specific element.
  • Average Order Value (AOV): The average amount spent per order.

By analyzing these metrics, you can identify areas for improvement and prioritize your CRO efforts. Use data visualization tools to present your findings in an easy-to-understand format.

Don't Set and Forget

Continuously test and refine your CRO strategy.

The online landscape is constantly evolving. The needs and expectations of your customers will change over time, and your website should adapt. Continuously test and refine your CRO strategy to stay ahead of the curve. Here's how:

  • Regular A/B Testing: Continuously test different elements of your website.
  • Stay Informed: Keep up-to-date with the latest CRO trends and best practices.
  • Gather Customer Feedback: Use surveys and feedback forms to understand your customers' needs.
