How to Improve Your E-commerce Website Conversion Rate

This article explores the e-commerce website conversion rate in depth — an essential component of our wider guide to customer conversion rate. Research suggests that adding product videos can increase conversion rates by as much as 53 times (Onesty, 2026).

Among all the KPIs used in digital marketing, the conversion rate is non-negotiable. This holds even more true in online retail, where the conversion rate shows what proportion of your website visitors become paying customers. The conversion rate of an e-commerce website is therefore critical, as it directly affects revenue. It also enables you to evaluate the effectiveness of the different marketing strategies you put in place. In short, it is a metric well worth monitoring closely.

Definition and How to Calculate an E-commerce Website Conversion Rate

An e-commerce website conversion rate is the ratio between the number of people who purchase one of your products or services and the total number of visitors (or sessions) on your website over a given period. For example, if you sell smartphones and you record 100 purchases in January from 1,000 visitors, your e-commerce website conversion rate is 10% (100 ÷ 1,000 × 100).

How Do You Measure the Conversion Rate of a Website?

There are highly effective tools — such as Google Analytics and Incremys — for tracking the conversion rate of an e-commerce website. You simply need to configure the platform correctly, including specifying what constitutes a conversion (typically a completed purchase). Once set up, you gain access to detailed reports that let you monitor your conversion rate and, crucially, how it evolves over time. This is essential for measuring whether your strategies are delivering results.

When analysing performance, it is helpful to break down your overall rate by separating your SEO conversion rate from your paid search (SEA) conversion rate. You can go further still by segmenting by email campaign or specific social channel, depending on your needs.

What Counts as a "Good" E-commerce Conversion Rate?

What is a good average conversion rate for an e-commerce website? The answer varies depending on your business model, your sector and a range of other factors — there is no universal benchmark. The most meaningful approach is to compare your rate against your direct competitors, and ideally against the top performers in your market.

How to Improve Your E-commerce Website Conversion Rate

Google Analytics allows you to study visitor behaviour at every stage of the conversion funnel, helping you identify which pages perform well and which need attention. Below are several proven methods to optimise your conversion rate.

A/B Testing

In most cases, a weak conversion rate can be traced back to a disappointing user experience.

A/B testing lets you compare two or more versions of a page and measure outcomes, including conversion rates. You retain the best-performing version and use it as the starting point for the next round of testing. Typical tests cover CTA format and placement, overall page design, and whether pop-ups help or hinder conversions.

Tackling Basket Abandonment

Basket abandonment is a persistent challenge for e-commerce businesses. Rates vary by sector, but it is common for around two-thirds of baskets never to convert into purchases. Key areas to address include:

• Implement a standard, compliant HTTPS setup. This is a baseline requirement for any transactional website.
• Keep the payment page simple, clear and reassuring. It must also be technically sound — no errors and fast response times across all devices.
• Display all costs (delivery, handling, etc.) before the payment step, ideally from the very start of checkout. The earlier customers know the total, the better the conversion rate tends to be.
• Make account creation smooth and low-friction. Draw inspiration from leaders such as Amazon or Hotels.com, whose registration flows are specifically designed to support transactions.

Following up on abandoned baskets is a well-established best practice. Leading e-commerce brands often send timely reminders when a customer drops out mid-purchase, because recovering those baskets depends on acting quickly and following up at the right moments. This is why these workflows are typically automated.

Common reasons for basket abandonment include:

• Lack of trust in the payment method — customers need absolute confidence when entering card details. HTTPS is a minimum requirement.
• A payment page that does not feel professional, which can undermine trust (design, layout and content quality all play a role).
• Unexpected fees appearing at basket stage, such as delivery or handling charges.
• An overly time-consuming account creation process, which risks discouraging customers from completing their purchase.

Act on abandoned baskets promptly: the longer you wait, the lower your chances of converting. Automation is generally the most reliable approach for managing these follow-ups at scale.

Simplify the Conversion Funnel

The customer journey is often visualised as a funnel, with the customer progressing towards a goal — typically a purchase. The shorter and simpler the path, the higher the conversion rate is likely to be. Analysing your funnel helps you identify unnecessary steps and reduce friction. For example, you can consolidate actions onto a single page, such as combining the order summary and delivery selection.

If completing a purchase requires too many steps — clicks, scrolling, form fields — visitors are likely to give up. This directly affects your e-commerce website conversion rate. Streamlining the process wherever possible is one of the most impactful improvements you can make.

Do Not Neglect Mobile

Mobile usage continues to grow, including for online purchases. It is essential to deliver a mobile user experience that follows best practice: fast load times, readable font sizes, thumb-friendly CTAs and a checkout that works seamlessly on smaller screens. Ongoing testing and refinement will help you lift conversions across all device types — mobile, tablet and desktop.

Smartphones have overtaken desktops for internet browsing for several years now. Even if mobile conversion rates still lag behind desktop in some sectors, underinvesting in mobile UX is a costly mistake. A responsive website is a baseline requirement, alongside strong performance and intuitive usability throughout the purchase journey.

E-commerce and GEO: How Generative AI Is Influencing Conversion Rates

E-commerce is particularly affected by the rise of generative AI. Consumers increasingly use tools such as ChatGPT and Perplexity to compare products, read reviews and receive personalised recommendations before making a purchase. This behaviour is reshaping the buying journey and the levers that drive conversion.

• AI-led product comparisons: AI engines generate comparison tables drawing on multiple sources. Product pages that incorporate structured data (price, specifications, reviews, availability) are more likely to be cited in these comparisons, boosting both visibility and qualified traffic to your site.
• Basket abandonment and AI-driven reassurance: A hesitant buyer may ask an AI tool whether a particular shop or product is trustworthy. If your brand features positively in those responses — thanks to strong reviews, clearly stated guarantees and a transparent returns policy — basket abandonment rates are likely to fall.
• Product SEO and "citability": Category and product pages optimised for SEO are also the most frequently cited by AI tools. Enriching these pages with FAQs, buying guides and structured comparisons improves both organic search rankings and AI visibility simultaneously.

The Incremys platform includes monitoring for product visibility within AI-generated responses, helping you optimise your e-commerce website conversion rate in the age of generative AI.

Frequently Asked Questions

What is the average conversion rate for an e-commerce website?

The average e-commerce website conversion rate typically sits between 1.5% and 3%, depending on the sector. The best-performing online shops can reach 5% to 8%. Key drivers include loading speed (under 3 seconds), product page quality, checkout smoothness, available payment methods, and delivery and returns policies.

How can you reduce basket abandonment on an e-commerce site?

The main levers are: simplifying checkout (aim for no more than three steps), displaying delivery costs early in the journey, offering guest checkout, providing multiple payment methods, sending automated reminder emails within two hours of abandonment, and adding trust signals such as security badges, guarantees and free returns where possible.

Which KPIs should you track for an e-commerce site?

Essential KPIs include: overall conversion rate, basket abandonment rate (typically around 70%), average order value, customer acquisition cost (CAC), customer lifetime value (CLV), product return rate and revenue per visitor. Segment each KPI by acquisition channel (SEO, paid search, direct, social) to optimise budget allocation effectively.

How do you calculate an e-commerce website conversion rate?

The formula is: (number of orders ÷ number of sessions or visitors) × 100. Example: 250 orders from 10,000 sessions = 2.5%. For reliable tracking, use a consistent definition (sessions versus unique visitors) and segment by device and channel (SEO, paid search, email, social).

What is the difference between "conversion rate" and "e-commerce website conversion rate"?

In practice, these terms refer to the same KPI in an e-commerce context: the share of visitors (or sessions) that complete the desired action — usually a purchase. The distinction is largely one of scope and context: a general "conversion rate" can apply to any goal (newsletter sign-ups, form completions, etc.), whereas an "e-commerce website conversion rate" specifically measures purchase completions.

Why is my e-commerce website conversion rate falling while traffic is increasing?

Common causes include: less qualified traffic (overly broad campaigns or SEO targeting informational queries), out-of-stock products, higher delivery fees, deteriorating Core Web Vitals or load times, mobile friction, or changes to the checkout flow. Break the drop down by channel, device and funnel stage to isolate where the issue originates.

What are the most effective SEO levers for improving an e-commerce website conversion rate?

Prioritise: category pages aligned with purchase intent, richer product pages (social proof, FAQs, comparisons, structured data for Product, Review and FAQ schemas), internal linking towards high-margin products, and reassurance content covering delivery, returns and guarantees. More qualified SEO traffic mechanically improves your e-commerce website conversion rate.

How can you improve conversion rates on mobile?

Focus first on: speed (under 3 seconds), clearly visible CTAs, short forms, one-click payment options (Apple Pay, Google Pay), autofill support, and a checkout designed for thumb navigation. Measure mobile and desktop conversion rates separately — differences often reveal device-specific UX friction that is straightforward to address once identified.

How should you segment your conversion rate to make better decisions?

Segment by: source and medium (SEO, paid search, email), device, new versus returning users, product category and country. Then cross-reference with average order value and margin. The ultimate goal is to optimise profitability, not simply to chase a higher conversion percentage in isolation.
