Success story

Serpent Forge, renowned for its quality men’s jewelry, collaborated with VWO to enhance its eCommerce experience. By clarifying payment options on product pages, Serpent Forge aimed to increase add-to-cart clicks.

Noticing customer confusion over the exclusive visibility of the PayPal installment option, Serpent Forge hypothesized a solution. They proposed that showcasing all payment methods—including Apple Pay, Google Pay, Mastercard, and Visa—near the add-to-cart button would streamline the checkout process.

A decisive A/B test involved over 2600 site visitors, comparing the original layout with a new version featuring multiple payment badges. The results were striking: the variation led to an 82% increase in add-to-cart clicks and a 32% boost in checkout page clicks, affirming the importance of clear payment information in enhancing the shopping experience.

VWO empowered Serpent Forge with its robust web optimization capabilities, driving impactful results. If you’re curious to see how VWO can transform your website’s performance, start with a fully-featured 30-day free trial to explore its full potential firsthand.

Choosing the right website optimization tool

Choosing the right website optimization tool is vital for boosting user experience and reaching your digital goals. Here are some key features to consider when evaluating and selecting a tool:

1. Minimum impact on website speed

Many optimization tools require adding a tracking code in the <head> section of your web page, whether for audits, A/B tests, or personalization. These tracking codes can sometimes slow down your website, so it’s important to prioritize tools that have minimal impact on website performance.

Key considerations:

• Use tools designed to minimize performance impact.
• Test potential impact with third-party speed tools before implementation.
• Review the tool’s documentation or knowledge base to understand how it may affect load times.

Optimizing your site should always enhance user experience, not compromise it with slower performance.

2. Comprehensive feature set

Website optimization goes beyond improving a single aspect; it’s a comprehensive process that requires a focus on the entire website. Choosing a tool that covers multiple aspects of optimization can save time, reduce back-and-forth, and streamline your workflow.

Key benefits to look for:

• Analyze user behavior and capture insights in one place.
• Convert observations into actionable hypotheses.
• Run A/B tests or implement other optimization strategies seamlessly.
• Gain a holistic view of your optimization efforts to make informed, impactful changes.
  

Tools like VWO offer all of this within a single dashboard, enabling a cohesive, efficient, and effective optimization process.

3. Seamless integration with all major platforms

When choosing a web optimization tool, seamless integration with your existing CMS or CRM is crucial to avoid data management headaches. Look for a tool that fits effortlessly into your tech stack and makes the entire optimization process more efficient and hassle-free.

Key points to consider:

• Look for a robust integration library that connects with your current digital tools.
• Saves time and reduces manual data handling.
• Enables cross-platform data connection, expanding your marketing capabilities.

Overall, it expands your scope of marketing activities by connecting data across platforms, enabling you to explore different strategies for better results.

4. Privacy compliant 

With digital regulations tightening and a greater focus on privacy and data protection, it’s essential to prioritize tools that safeguard user data. You wouldn’t want to jeopardize your users’ data while optimizing your website, so ensure your chosen tool is compliant with regulations like GDPR, CCPA, and HIPAA.

Ideally, opt for a tool that’s also SOC Type 2 certified, as this indicates it upholds rigorous security protocols and consistently applies best practices to protect sensitive data.

5. Free trial or plan

Investing in an optimization tool requires a considerable commitment of money, time, and resources. To minimize risk, choose tools that offer an ample free trial period or a forever-free plan with essential features.

This allows you to thoroughly assess the tool’s capabilities and see how well it aligns with your business needs. By testing upfront, you gain confidence in the tool’s potential to deliver a positive ROI, ensuring you’re making a well-informed investment.

Final thoughts

To wrap up, website optimization is undeniably crucial for securing online success. Leveraging the right tools can make your site faster, more engaging, and accessible to every user.
