How to Increase eCommerce Conversion Rate: 20 Proven Strategies Supported by Science 

Product Discovery and Browsing Experience

If you’re looking at how to increase conversion rate for eCommerce, start with discovery. When shoppers can find what they need faster and with less effort, hesitation fades, and conversions improve.

1. Simplify Navigation & Speed Up Product Discovery 

Science behind this: Cognitive Load Theory - Shoppers subconsciously try to get the maximum value with minimum effort. 

When we audit a store, we often find navigation menus that resemble the flight deck of a Boeing 747: dozens of options, nested sub-menus, and "clever" labels that leave shoppers paralyzed. 

Human beings are notoriously bad at making decisions when faced with too many choices; in fact, 54% of shoppers have abandoned a brand because the site was too difficult to navigate (Gartner, 2024).

If a visitor has to think about where to click, we’ve already lost them. 

The ideal strategy is to move a user from "searching" to "finding" in under three seconds, which requires ruthless pruning. 

For example, for a luxury watch brand we recently consulted, we saw an 11% lift in revenue simply by consolidating fifteen category links into four intuitive buckets and adding a predictive search bar that actually understood typos. 

Remember that your navigation shouldn't be a map of your internal company structure; it should be a fun-filled slide toward the "Add to Cart" button.

2. Optimize Mobile UX for Better Shopping Experiences

Science behind this: Change blindness, a visual phenomenon, can cause shoppers to miss key elements in their mobile journey, leading to lower conversions. We’ve also experienced that mobile storefronts are little more than "squished" versions of the desktop site.

In reality, mobile devices account for roughly 77% of all retail site traffic (Adobe Analytics, 2024), yet mobile conversion rates consistently lag desktop conversion rates by nearly half. The culprit is usually "thumb fatigue." 

We see sites where buttons are so small they require the precision of a watchmaker. And there are pop-ups that effectively hijack the entire screen. 

During a recent audit for a high-growth apparel brand, we replaced traditional drop-down menus with "sticky" bottom-of-screen navigation and simplified the form fields. The result was a 19% increase in mobile checkout completions!

To win on mobile, you must design for the distracted thumb: make the "Add to Cart" button impossible to miss and ensure the page loads in under two seconds.

3. Turn Wishlists & Micro-Conversions into More Sales

Science behind this: The design of micro-conversions relies on developmental milestones, the idea that a set of markers along a journey must be met before final maturation or the destination (in this case, a macro conversion).

Did you know 88% of shoppers research online before making a purchase (Salesforce, 2024)? That’s why we shouldn't view a non-purchase as a failure.

But sadly, most brands treat the "Wishlist" as a graveyard, a place where products are forgotten. Instead, we should view it as a "micro-conversion" that signals high intent. Your goal is to bridge the gap between "just looking" and "buying now." 

During a recent audit of a B2C subscription brand, we found that users who interacted with a wishlist were 4x more likely to convert when appropriately nudged.

We implemented automated "back-in-stock" and "price-drop" alerts specifically for items in those lists, which generated a 14% boost in recovered revenue. 

Instead of a static heart icon, treat the wishlist as a personalized shopping assistant. Use that data to fuel your email retargeting and on-site personalization. 

This way, you can turn your “Add to Wishlist” into a revenue engine. Here’s an interesting example from Forever 21:

4. Match Landing Pages to Ads for Higher Conversion Rates

Science behind this: Expectation Confirmation Theory - When incoming information doesn’t match, it creates cognitive friction and exit behavior.

Now, this is something very common: ​​A shopper clicks a specific ad for "blue linen shirts," only to be dumped onto a generic homepage. This message mismatch is a conversion killer.

In our audits, we focus on scent-trail optimization. 

If the ad promises a specific solution, the landing page must echo that exact headline and imagery.

For a luggage retailer we recently helped, aligning landing page copy strictly with their Meta ad creative reduced bounce rates by 22%.

Hence, ensuring that your landing page messages match your ad creative is an essential way to improve your eCommerce conversion rate.

5. Localise Your Store to Increase International Conversions

Science behind this: Cultural Fluency Effect - Stimuli that align with cultural norms are processed more easily and trusted more, leading to faster decisions and higher conversion likelihood.

Let’s face it: Selling to a customer in Tokyo or Berlin using a "US-centric" store is a recipe for high bounce rates. 

Data suggests that 76% of online shoppers prefer to buy products in their native language (CSA Research, 2024), and even more will abandon a cart if they can't pay in their local currency.

At Convertcart, we look for "cultural friction" in our audits. For a global electronics client, we replaced generic shipping estimates with local carrier icons and integrated regional payment methods such as Klarna and Pix. 

This single shift in localization strategy led to a 27% increase in international checkout conversions. 

You must remember that localization isn't just about language; it’s about making a shopper 5,000 miles away feel like you’re closeby. 

Product Page Persuasion and Decision Making

Product pages play a critical role in increasing conversion rate on an eCommerce website.

When you combine clear messaging, persuasive design, and confidence signals, your product pages become the foundation of effective eCommerce conversion rate optimization. Let’s learn how.

6. Write Product Descriptions That Convert Better

Science behind this: Cognitive Fluency - The brain prefers information that’s easy to process and emotionally engaging. Research indicates that 20% of purchase failures are due to poor or incomplete product information (Nielsen Norman Group, 2024).

Unfortunately, on many eCommerce stores, product descriptions read like a dry technical manual or, worse, a series of vague marketing superlatives.

We advise our clients to stop listing features and start solving problems. 

For a skincare brand we recently audited, we shifted their copy from "contains hyaluronic acid" to "keeps your skin hydrated for 24 hours in dry weather." 

By addressing the specific "why" behind the "what," they saw a 15% lift in conversion rates. An expert description should do three things: mirror the customer’s language, answer their unspoken "Will this work for me?" and remove any excuse to click away. Not that complicated, or is it?

7. Use High-Quality Images & Videos to Reduce Returns

Science behind this: Context Principle - When shoppers can’t physically interact with a product, the brain looks for visual context to fill the gap.

We’ve seen that high-resolution zooms and 360-degree videos aren't just "nice-to-haves"; they are risk-reduction tools. 

For a home-goods client, we introduced user-generated video reviews and scale-comparison photos. This transparency didn't just boost confidence; it slashed their return rate by 14%. 

Offering high-quality video and images in your eCommerce store enhances a real, believable experience. In fact, 22% of returns happen because the product looks different in person (Invesp, 2024).

So, here’s the bottom line: If you show your product the way they are, your customers love buying from you!‍

8. Add Relevant Social Proof & Personalized Reviews

Science behind this: Sequential Trust Building - Shoppers don’t trust everything at once. At each funnel stage, the brain looks for the most relevant proof it can easily recall.

When our experts audit an eCommerce site, they look for the "lonely restaurant" effect. No matter how sleek your design is, if it lacks visible human validation, shoppers feel like they’re the first to walk through your doors. 

Data shows that 95% of consumers read online reviews before making a purchase (PowerReviews, 2024).

However, generic reviews are no longer enough. We help you focus on contextual social proof. 

For a footwear client, we replaced a standard star rating with a filterable review section that allowed shoppers to see photos and feedback from people with their exact foot width. 

This layer of personalization led to a 16% jump in conversions. This shows that if you show each customer relevant social proof, you’ll see a marked improvement in your conversion rates.

9. Use Pre-Orders to Drive Early Sales & Hype

Science behind this: Pre-orders relate to the psychology of hype that amplifies any announcement of a scarce resource, and they become a marketing tactic in their own right.

When we audit eCommerce brands launching new collections, we often find that they wait until the inventory is physically in the warehouse before starting to sell. This is a massive waste of momentum. 

Research indicates that pre-orders can account for 15% to 20% of a new product launch's total lifetime sales (Shopify, 2024).

For a consumer electronics client we audited, implementing a "limited-run" pre-order strategy complete with a countdown timer and exclusive "early bird" updates resulted in a 24% increase in Day 1 revenue. 

The idea is to turn a “Coming Soon” page into a revenue-generating channel. This strategy also allows you to build a community of early adopters.

Trust, Risk Reduction & Reassurance

Shoppers don’t abandon your product because they dislike it; they leave because something feels uncertain. Reducing that risk through trust and reassurance is a core eCommerce conversion rate optimization principle. Let’s understand how.

10. Build Trust with Clear & Visible Return Policies

Science behind this: Commitment Escalation - Shoppers invest in microcommitments first before macro-converting. ‍

Is your return policy hidden in the footer, written in a dialect of "legalese" that would baffle a Supreme Court justice? 

If yes, this is a critical error. 

You must know that shoppers don't view a return policy as a way to leave; they view it as a safety net that gives them the confidence to stay. 

In fact, 67% of shoppers check the return policy before making a purchase, and a staggering 92% will buy again if the return process is easy (Invesp, 2024).

We recommend moving this "anxiety-killer" front and center. Make your policy clear, generous, and easy to understand. In our experience, it’s one of the most effective ways to improve your website conversion rate.‍

11. Improve Live Chat to Boost eCommerce Conversion Rate

Science behind this: The principle of interactivity, which is especially relevant in Web 2.0, treats clear & real-time communication as a cornerstone of customer experience.

Do your eCommerce live chat windows behave more like polite ghosts, either unresponsive or manned by bots that aren’t good for anything? 

This neglect is costly. 

Research shows that shoppers who use live chat are 2.8x more likely to convert than those who don't (Invesp, 2024).

In our audits, we prioritize speed and human touch. 

For a specialty home-decor brand, we implemented "proactive triggers" to offer assistance when a user spent more than 60 seconds on a complex technical specs page. 

By shifting from a reactive "wait-and-see" model to a proactive expert-led chat, we saw a 21% lift in average order value. Live chat shouldn't be a secondary support ticket system; it should ideally be a high-performance sales tool that kills hesitation in its tracks. Do you agree?

Cart, Checkout & Conversion Friction

If you’re focused on improving your eCommerce website conversion rate, start with checkout. Simplifying the process and eliminating surprises helps reduce abandonment and directly increases conversion rates.

12. Make Your Cart Page More Persuasive & Profitable

Science behind this: Choice Architecture - When options are presented (or the flow in which people see them), shoppers decide how they will choose and act on them.

We often find cart pages treated as mere "waiting rooms," which is quite disheartening, honestly. This is where the "Will I regret this?" jitters set in. 

With the average cart abandonment rate sitting at a stubborn 70.19% (Baymard Institute, 2024), your cart page needs to be your most persuasive salesman.

We always recommend you focus on reinforcing value on the cart page. 

For a wellness brand we recently consulted, we added clear "Free Shipping" progress bars and visible trust badges right next to the subtotal. We also included a "Save for Later" option to prevent frustrated exits. 

These small psychological safety nets led to a 14% reduction in abandonment. Your cart page is an opportunity to close the deal, and that’s why you should work toward making the most of it.

Beauty brand Cocokind, for example, features a “build your routine” nudge in their cart with complementary products that a shopper will find easy to use together:

13. Stop Cart Abandonment with Smart Exit-Intent Popups

Science behind this: Loss Aversion - People are essentially more afraid of losing something than of gaining something else.‍

Do your popups feel like a desperate digital "Wait, come back!" cluttered, poorly timed, and ultimately annoying? However, when executed with precision, these are conversion frontliners. 

Studies show that exit-intent overlays can recover up to 10%-15% of visitors who abandon (OptinMonster, 2024). The secret is relevance, not just a generic discount code. In our audits, we move away from "one-size-fits-all" popups. 

For a high-ticket furniture retailer, we implemented a "trigger-based" offer that appeared only when a user was about to leave a cart worth over $500, offering a personal design consultation rather than just 10% off. 

This nuanced approach led to a 19% increase in lead capture. Don’t forget that an exit pop-up should be a well-timed solution to the specific hesitation that’s making your customer walk away.

14. Create a Frictionless One-Page Checkout Experience

Science behind this: Transparency Principle + Zero Price Effect - Checkout is where uncertainty peaks. When shoppers feel unsure about costs, steps, or errors, they pause or abandon.

We audit numerous eCommerce checkout flows every week. And the most common flaw is that many of them feel like a grueling interrogation. Some of them have multi-page forms that are an ordeal for prospective customers. 

Research shows that 17% of shoppers abandon their carts solely because the checkout process was too long or complicated (Baymard Institute, 2024).

For a direct-to-consumer beauty brand, we stripped away distractions, made "guest checkout" the default, and used address auto-complete. 

By removing the "Next" buttons that usually trigger anxiety, we saw an 18% jump in completed transactions. Don’t forget that the checkout process is when you should step aside and let your customers complete their purchase.

15. Write High-Converting CTAs That Motivate Action

Science behind this: Frogg Behavior Model - Behavior is a result of motivation multiplied by ability multiplied by prompt. 

Have you come across a CTA on your site that feels like a limp handshake? Buttons like "Submit" or "Buy Now" are functional, but they are utterly devoid of motivation. 

They tell the user what to do, but they don't tell them what they’re getting. Data indicates that personalized CTAs convert 202% better than basic ones (HubSpot, 2024).

In our audits, we suggest clients to move away from generic commands toward "benefit-driven" language. We recently worked with a subscription brand and we changed a "Sign Up" button to "Start My Free Trial." 

This shift from a chore to a reward helped drive a 22% increase in click-through rates. A high-converting CTA should spark desire. That’s why you need to examine every CTA on your site with that perspective. 

Offers, Incentives & Motivation Triggers

The right incentive at the right moment can dramatically accelerate decisions. Strategic urgency, smart discounts, and clear pricing cues are proven tactics in eCommerce conversion rate optimization. Let’s learn more about these strategies in this section.

16. Use Authentic Urgency Tactics

Science behind this: Loss Aversion - People are more motivated to avoid losing something than to gain something new. 

The bitter truth is that shoppers have developed a keen nose for fake countdown timers and perpetual "last chance" sales. However, when urgency is authentic, it’s a psychological powerhouse; research shows that genuine scarcity can increase sales by as much as 226% (ConversionXL, 2024).

The key is transparency. In our audits, we focus on "inventory-driven" urgency. 

For a shoe brand, we replaced generic "Hurry!" banners with real-time stock levels "Only 3 left in your size." 

By shifting from manufactured pressure to helpful information, we saw a 14% lift in conversion rates. Authentic urgency shouldn't feel like a trap; it should feel like a service, ensuring your customer doesn't miss out on something they truly want.‍

17. Smart Pricing Strategies to Increase Average Order Value

Science behind this: Psychological pricing hits the “sweet spot” the shopper finds appealing (based on competition, perceived value, etc.) and convinces them to buy more.

As an eCommerce store, if you’re competing only on price, you’re effectively competing in a race to the bottom. Pricing isn't just a number; it’s a communication tool. 

According to recent data, 73% of consumers say they are more likely to buy when a brand offers a "bundle and save" option (McKinsey, 2024), yet many stores leave these potential gains on the table.

At Convertcart, we believe in the power of anchor pricing and tiered incentives.

For a high-end supplement brand we recently audited, we introduced a "Good, Better, Best" pricing tier. 

By highlighting a "Most Popular" mid-tier option that offered slightly better value than the base unit, we shifted 31% of their customer base to a higher price point overnight. 

Whether it’s through volume discounts or "Free Shipping at $X" thresholds, your pricing should guide customers toward a larger commitment without making them feel pressured.

Personalization, Retention & Lifetime Value

One of the most sustainable ways to increase conversion rate for eCommerce store is to make future buying decisions easier.

Through personalization, retention, and post-purchase improvements, brands continually improve conversion rates beyond the first sale. Let’s see how.

18. Personalize the Full Customer Journey for Higher Retention

Science behind this: Cognitive Ease - Shoppers convert faster when every step in the journey feels easy, relevant, and predictable. 

You need to understand that your eCommerce store has a "leaky bucket" problem if it has plenty of new traffic, but a complete failure to recognize the customer when they return. Research shows that personalization can deliver five to eight times the ROI on marketing spend and lift sales by 10% or more (McKinsey, 2024).

In our audits, we push beyond basic "First Name" email tags. 

For a subscription-based beauty client, we implemented dynamic product grids that displayed "Recommended for Your Skin Type" based on previous purchases. 

This shift from a generic storefront to a curated experience drove a 24% increase in repeat purchase rates. 

Personalization isn't about surveillance; it's about relevance. 

When you tailor the journey, you’re building a relationship that survives the next competitor's discount. And that matters a lot. 

19. Turn Post-Purchase into Repeat Buyers & Loyalty

Science behind this: Peak End Rule -  People judge an experience largely by its emotional peak and how it ends. A strong post-purchase phase disproportionately shapes memory and future buying behavior.

This is true for many eCommerce stores we’ve audited in the past: all communication dies the moment the credit card clears. The ideal strategy is to treat the "Thank You" page as the beginning of the next sale, not the end of the current one. 

For a sustainable apparel brand, we replaced the generic confirmation with a personalized "How to Style" video and an invitation to a tier-based loyalty program. 

By transforming a transactional email into a value-add touchpoint, we saw a 19% lift in second-purchase frequency within 30 days. Here’s the lesson: don’t just ship a box; ship a reason to return.

Experimentation & Continuous Optimization

If you’re trying to learn how to increase conversion rate on an eCommerce website, continuous testing is essential. Data-led experiments are at the core of eCommerce conversion rate optimization and show brands exactly how to increase sales over time.

20. Data-Driven A/B Testing to Boost Conversion Rates

Science behind this: Behavioral Empiricism - Observed behavior is more reliable than self-reported preference. Controlled experiments reveal what truly influences decision-making.

Let’s get real.

Is your conversion strategy based on data, or are you just "throwing spaghetti at the wall"?

When we audit eCommerce stores, we frequently find that million-dollar decisions are being made on the whims and fancies of what some people think might work. 

In our audits, we replace guesswork with clinical precision. 

For a high-volume electronics retailer, we A/B tested a standard "Buy Now" button against a "Check Compatibility" CTA on complex product pages. That single shift in psychological framing triggered a 22% increase in checkout starts. 

Do you see how it works? That’s why data-driven A/B testing is one of the most crucial aspects of scientific eCommerce CRO.

Final Thoughts
