Before we begin, we'll go over a few factors to consider when comparing CRO software for your e-commerce brand.

Factors to Consider When Evaluating Conversion Rate Optimization Software for Your Online Store

#1: How Does it Improve User Experience?

Different tools increase conversion rates in different ways. But they all have 1 thing in common:

CRO tools improve user experience.

When evaluating CRO software, you need to look at how exactly the tool improves user experience.

• Is it a conversational experience that guides your customers to the right products and answers their questions?
• Is it by personalizing the product discovery experience via an AI site search?
• Is it by creating a user-centric design for your website?
• Is it an A/B testing feedback mechanism that incorporates user feedback to make continuous improvements?

#2: Does The Tool Have In-Depth Analytics & Reporting on Conversion Data?

The CRO software you choose needs to have comprehensive data tracking so you can evaluate the results.

The tool should track user behavior, conversion paths, and even drop-off points to provide actionable insights.

Some of the tools would also give you access to bonus insights, such as what products are bought together, so you can further improve your online store's experience.

#3: Does The Tool Enable You to A/B Test & Iterate?

CRO tools for e-commerce should be customizable. They enable your brand to conduct A/B tests and iterations as you gain more insights.

Any effective conversion rate optimization tool would have options to continuously test and iterate on new strategies and approaches, comparing what improves the conversion rate the most.

These tests should be easy to set up and without the need to involve developers.

#4: What is The Pricing Structure?

To improve your bottom line, you need to be thinking about the return on investment (ROI) from the tool.

Different tools have different pricing models, so you will have to choose a pricing structure that works for your brand.

Some e-commerce CRO tools offer a % commission for each sale attributed to their software, while others require a monthly subscription.

Other things to consider are the tool's scalability to accommodate large amounts of customers and data and its integration with your CMS.

Big Sur AI's Features

AI Sales Agent

Big Sur's AI Sales Agent is like having a dedicated shopping assistant for every customer.

Your consumers can ask Big Sur’s AI Agent contextual questions about your products from anywhere on your site - such as comparing different products.

Here’s an example from Rad Power Bikes ⤵️

The sales agent is trained to provide personalized answers based on the information about your products, site content, and each customer’s engagement with your store.

For example, customers can ask the tool for product recommendations based on their personal attributes, such as their height ⤵️

Here's why e-commerce brands adopt Big Sur AI:

• 24/7 Real-Time Assistance: Big Sur AI's Sales Agent helps customers find the right product at any time of the day without relying on human agents.
• Customized to your store: You control the AI experience, and the tool is fed and trained with your store’s information.
• Optimized for conversions: Our AI Sales Agents' advice is designed to provide relevant product recommendations and propose follow-up questions on a data-driven basis.
• Human-like conversational experience: Your shoppers can talk to Big Sur’s agent as if they were messaging a human.

Conversion-Optimized AI Prompts

Our tool prompts your customers to start more conversations, which increases conversion rate and average order value (AOV).

Big Sur AI analyzes how each customer engages with your online store and predicts which questions they'll most likely ask.

The software then suggests these questions throughout their shopping experience.

Here’s an example from Wyze ⤵️

Big Sur AI helps shoppers alleviate hesitations before purchasing, as they know more about your products.

💡 Customers who interact with the AI Sales Agent convert at 4 times the rate as the average store user.#

These AI prompts are embedded on your product and collections pages and are personalized to every customer.

💡Different users would see different questions that are crafted to maximize the likelihood of converting.

AI Product Recommendations

When customers go to conventional stores, they receive generic product recommendations, such as:

• Most purchased products overall.
• Frequently bought together.

These recommendations are the same for everyone and are not personalized for each customer.

Big Sur AI increases your store's conversion rate by making contextual product recommendations based on:

• Shoppers’ engagement with your store, such as product views and buttons clicked.
• Information gathered through the conversational experience.
• The questions they asked.

Our software's AI-powered product recommendations are broken into 3 modules and are shown to your customers based on the page they are on and how they got there:

• Picked for you: Displays a selection of products that a customer is likely to buy based on what the tool knows about them.
• Frequently bought together: Product recommendations that appear once a shopper adds a product to their cart. The recommendations feature other products that customers typically buy based on their previous site activity.
• Top sellers: The tool shows the best-sellers in the same product category as the product a user is considering, combined with the shopper's gathered information - not just generic recommendations.

Your shoppers can receive these product recommendations on your product pages or during a conversation with the AI Sales Agent, drastically increasing conversion rates and basket sizes.

Merchant Insights

Big Sur AI gathers unique insights that help online stores make better strategic decisions.

First, our tool helps you uncover what your customers want to know when browsing your products and how questions correlate to purchasing behavior.

Your brand will also get insights on what questions lead to conversions vs. abandonment ⤵️

Get insights into what products are frequently bought together to help you improve your store's customer experience:

E-commerce owners appreciate the ability to understand correlations between past purchases, customer profiles, and consumers' interactions with their online stores.

You can use these insights to improve your site experience, including merchandising and product descriptions, to build a marketing strategy based on what consumers really want.

Last but not least, you can see where shoppers churn and where the AI Sales Agent helped improve the conversion rate and sales volume:

Pricing

Big Sur AI has 2 pricing models:

• Commission-Based Model - merchants only pay when they get sales from the AI Sales Agent.

This is a pay-for-performance model, where you only pay a commission for each sale attributed to our software.

The conversion window is negotiated, but it’s typically 30 days.

• Tiered Pricing Model - recurring monthly payment based on your average volume of unique visitors per month.

Think of these pricing models as if you’re hiring a salesman.

You choose between paying per unique visitor to your website or a commission on each sale attributed to Big Sur AI.
