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

PRODUCT DISCOVERY & 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, which leads to an increase in eCommerce conversion rates.

1. Simplify Navigation & Speed Up Product Discovery 

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

Imagine a shopper arrives excited, only to face a cluttered menu or too many confusing options, and they bounce to a competitor. 

Here are some ways to turn hesitant browsers into confident buyers and increase your conversion rate: 

You can tweak navigation so shoppers find products quickly. Limit top-level categories to four or five obvious ones. Add shortcuts like Recently Viewed or Wishlist for returning visitors.

Go further with surface filters on the homepage or category pages, use quick-view pop-ups for colors/sizes/details, and show personalized suggestions or bestsellers in search. With gentle cues like “Trending” or “Low stock”, nudge decisions naturally.

On product pages, you can add soft suggestions like “Shop similar styles,” “Other colors,” or “Pairs well with…,” to keep the flow going.

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. 

In eCommerce, around 70%-75% of traffic and over half of sales come from smartphones. If your mobile UX is not great, then you’re missing out on a ton of conversions.

We have seen behavior like tapping on “Add to Cart” and getting no clear feedback. Or people scroll through images and reviews, only to go hunting for the buy button again. These micro-frustrations add up fast.

Here are some small mobile improvements that cut hesitation, maintain momentum, and help more visitors become buyers:

When an item is added, let the cart icon give a quick bounce, shift color softly, or slide in the updated count. It’s subtle but instantly tells them the action worked and keeps the flow going.

Pin the “Add to Cart” or “Buy Now” button, so it stays visible as people scroll, no more searching every time.

For helpful urgency, use a gentle slide-in modal for limited-time deals with a small countdown timer at the bottom or side, plus an easy “X” to close. It nudges without trapping anyone.

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 need to be met before the final maturation or destination (in this case, a macro conversion).

Shoppers often take small steps before buying, like adding to a wishlist or signing up for emails, but many stores let those moments fizzle out. 

We have noticed this on many online retail stores, especially on beauty and fashion stores.

The key is turning them into seamless paths to actual sales, building on the idea that little milestones lead to the big win.

Wishlists are great for dreaming, but they gather dust if ignored. Keep them alive with gentle nudges during sales: a friendly note like “This would look amazing on you” or a style tip to remind them why it caught their eye. 

Follow up with alerts like “Your wishlist item is almost sold out” via email or push. It creates just enough urgency to draw them back, ready to buy, without feeling pushy.

For other micro-coversions, including email signups, start simple: a pop-up offering 10% off your first order. Then send a warm follow-up with a subtle countdown on the discount. It builds excitement progressively, making the process feel helpful and encouraging for that first purchase.

On product pages, especially pricier ones, add a “Compare” option prominently. 

Letting people line up items side by side cuts down hesitation and speeds up decisions, steadily lifting your overall conversion rates.

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.

One of the biggest killers of paid traffic conversions is the disconnect right after the click. The ad promises something exciting, glowing skin fast, huge savings, and total transformation. 

But the landing page switches to dry features, a different headline, or mismatched energy. The visitor feels confused or let down, breaking trust. And high-intent visitors leave without buying.

The simple fix: you could make the landing page feel like a seamless next step. Echo the ad’s core promise word-for-word in the headline. Keep the same tone, urgent ads get urgent, action-focused pages, and relaxed ones stay calm and reassuring.

To boost conversion rates from ads, answer the ad’s implied question right away, before adding anything else. Match visuals, offers, and calls-to-action perfectly.

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.

Familiar experiences feel safer and convert faster. Once you implement localisation, a powerful conversion rate optimization for eCommerce, you are removing every tiny barrier that makes international shoppers pause and think twice. 

When your eCommerce site shows prices in local currency with familiar formats, people are saved from doing the mental math to figure out the real cost. 

Shipping timelines match what people in that region expect, payment options feel instantly recognizable, and the language reads like it was written by a local, not run through a translator.

These thoughtful touches quietly build trust and comfort. Show exact delivery dates instead of vague “3-5 days,” highlight reviews from buyers in the same country, and list return policies with local addresses. Shoppers feel seen and safe, which directly helps improve eCommerce conversion rates.

Small, region-aware details like these create smoother experiences that encourage more clicks to purchase, making eCommerce conversion rate optimization feel natural rather than forced.

PRODUCT PAGE PERSUASION & DECISION-MAKING

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

When they combine clear messaging, persuasive design, and confidence signals, they become the foundation of effective eCommerce conversion rate optimization and help brands increase their eCommerce conversion rate.

6. Write Product Descriptions That Convert Better

Science behind this: Cognitive Fluency - The brain prefers information that’s easy to process and emotionally engaging. 

Shoppers scan product descriptions and rarely read every word. Dense or jargon-filled copy creates friction that hurts eCommerce conversion rates. 

We often encourage online store owners to read their copy aloud. If it sounds unnatural, complicated, or confusing, then you have to simplify it. 

Use the shopper’s own words from reviews, searches, and support chats instead of brand jargon. Familiar language builds trust fast. 

Add icons next to short text for steps, routines, or what’s included. Replace vague words like “premium” with action verbs: “glides,” “absorbs,” “stays cool.” This helps shoppers picture your product copy instantly.

Focus on benefits over features. Change “100% organic cotton” to “softer fabric that lets skin breathe and cares for the planet.” Show values like sustainability or fair trade right in the description so buyers feel emotionally connected.

You can swap generic “Add to Cart” for benefit-driven CTAs: “Claim My Cooling Pillow” or “Transform My Morning.” This reinforces value at the most decisive moment.

Cookware brand Anyday does this well by structuring descriptions to summarize, then specify, and finally build trust, a flow that keeps cognitive effort low while increasing confidence.

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. 

In eCommerce, strong visuals become the main way to build trust and reduce doubt. When photos or videos feel low-effort or incomplete, hesitation grows, and your eCommerce conversion rate suffers.

Use sharp, high-resolution images that look professional; blurry or poorly lit shots make people question quality right away. Show the product from multiple angles: front, back, sides, plus close-ups of textures, stitching, or special finishes. These extra views quietly answer questions shoppers have in their heads.

You can add smooth zoom that works well on mobile, so people can explore details the way they would in a store. Include clear scale references, models wearing the item, a hand holding it, or a familiar object next to it, to prevent size disappointment.

Videos go even further. Short, focused clips showing the product in real use help shoppers instantly imagine it in their own lives. 

Start with the biggest benefit in the first five seconds to catch attention. Add simple captions that highlight how it feels or sounds (“buttery soft,” “smooth glide,” “satisfying click”) so the message lands even when sound is off.

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. 

Every page on your site has one clear job: spark interest on category pages, build desire on product pages, or close the deal at checkout. Social proof works best when it quietly supports that specific role instead of overwhelming the shopper.

On category pages, where people are still browsing and deciding whether to dive deeper, use broad, high-level signals to create a sense of popularity and safety. 

Phrases like “Trusted by 5,000+ happy customers,” “This month’s best-seller,” or “Join 3,200 others, limited spots” normalize demand and gently pull visitors forward. These cues help improve eCommerce conversion rate early by making the store feel lively and reliable.

Product pages are where real hesitation hits, so shift to personal, relatable proof that answers “Will this actually work for me?”

Feature outcome-focused review snippets (“Cleared my stubborn acne in just two weeks”), reviews tied to specific benefits, and visual user-generated content showing real people using the product. 

This kind of authentic evidence builds emotional connection and directly supports how to increase eCommerce conversion rates.

Anxiety often spikes at checkout, so keep proof short, real-time, and reassuring: “Sarah from LA just bought this 2 minutes ago” or “You’re about to join 25,000 satisfied customers.” These messages ease last-second doubts and reinforce the decision without pressure.

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

Science behind this: Pre-orders relate to the psychology of hype that blows up any announcement of a scarce kind, and that becomes a marketing tactic on its own.

Pre-orders give shoppers a chance to secure something special before everyone else, which can spark excitement and lock in sales early. 

To improve your eCommerce conversion rate without making it feel forced, offer specific perks that feel genuinely rewarding: priority shipping so items arrive first, limited-edition packaging that makes unboxing memorable, or a small thank-you note from the team. These touches make early buyers feel valued and special.

You can also pair pre-orders with carefully themed bundles, limit yourself to two or three tiers with clear price differences. For example, a basic bundle, a mid-tier with extras, and a premium one with the most value. This variety caters to different budgets while guiding shoppers toward higher options.

Add exclusive bonuses available only through pre-order: digital downloads like guides or wallpapers, early access to future drops, or unique add-ons that vanish at launch. These extras answer the question “Why buy now?” and make the decision feel smart.

TRUST, RISK REDUCTION & REASSURANCE

Shoppers don’t abandon because they dislike your product; they leave because something feels uncertain.

Reducing that risk with trust and reassurance is a core principle of eCommerce conversion rate optimization and one of the most reliable ways to increase conversion rates for eCommerce.

10. Build Trust with Clear & Visible Return Policies

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

Nothing kills a potential sale faster than uncertainty about returns; shoppers hesitate, abandon carts, and your eCommerce conversion rate takes a hit. 

So, highlight your strongest return benefit prominently across landing pages, homepage, and ad destinations. A quick line like “Now enjoy a 45-day hassle-free return window” reassures visitors right away and encourages them to explore further.

Add a friendly “Learn More” expandable link wherever you mention returns, even in small microcopy. Clicking it opens a clean modal with key highlights, bullet points on the process, no restocking fees, and easy labels, so shoppers get answers without leaving the page.

Link to the full policy at every big decision point: product pages near the add-to-cart button, cart summary, checkout steps, and even in live chat. Visibility at these moments reduces last-second doubt and makes buying feel low-risk.

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.

Live chat can be a game-changer for eCommerce conversion rate when it actually solves problems instead of adding friction. The smartest stores blend AI with human touch to keep support fast and personal.

Train AI chatbots to quickly handle common questions like sizing, shipping times, or returns, then smoothly hand off tougher queries to real agents so no one feels stuck. 

To improve conversion rates, personalize every interaction. Greet visitors by name and suggest items based on what they’ve viewed or added to cart. This makes the conversation feel thoughtful and relevant.

Set clear expectations for availability, offer 24/7 AI coverage, and promise a human reply within a specific window if needed. Use proactive nudges triggered by behavior, like “Struggling to pick the right size?” or “Questions about this color?” at the perfect moment.

CART, CHECKOUT & CONVERSION FRICTION

If you’re focused on how to increase conversion rate on an eCommerce website, start with checkout.

Simplifying the process and eliminating surprises helps reduce abandonment and directly supports increasing eCommerce conversion rate.

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. 

The cart page is your last chance to win the sale before checkout, and small psychological tweaks can make it far more inviting. 

Auto-apply relevant discounts and highlight them with fresh microcopy like “Your 15% off is active!” Anchor the savings clearly next to the original price so the value hits home and builds conviction instantly.

Frame urgency in personal, relevant ways that feel helpful instead of manipulative: “Your size M is almost gone. Secure it now,” or “Checkout in the next 30 minutes for same-day dispatch.” These targeted nudges make action feel natural and timely.

To improve eCommerce conversion rates, you can also gamify the progress bar by breaking it into multiple benefit thresholds beyond just free shipping. Show steps like “Add $10 more for free gift wrap” or “$20 away from a bonus sample.”

Beauty brand Cocokind, for example, features a “build your routine” nudge in their cart with some discounted options, but largely 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.

Exit-intent pop-ups can save carts that are about to vanish, but generic messages feel spammy and drive people away faster. The real power comes from tailoring the offer to exactly where someone is in their buying journey, turning hesitation into action, and helping to improve eCommerce conversion rates at critical moments.

For new visitors, try something timely: “Leaving already? Your 20% discount expires with your cart in [countdown timer].” 

High cart value shoppers respond well to “Your bag qualifies for free express shipping, but only if you finish checkout now.” Loyalty members might stay for “You’re about to miss 120 reward points, enough for $12 off your next order.”

Discount seekers love interactivity: “Want a discount top-up? Spin to win and apply!” High-intent shoppers who linger on details get nudged with “Need help choosing? Take our 30-second quiz and get 5% off.”

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.

Checkout is where most of the abandonment happens, often because of surprise fees, confusing steps, or lingering doubt. That’s why one-page checkout remains among the strongest ways to improve the eCommerce conversion rates. 

Offer one-click checkout for returning customers who have saved their details, plus express options like Apple Pay, Google Pay, and PayPal that cut down on typing and decisions. Let people save their cart for later so they never lose progress. 

You can use smart, inline error messages that explain exactly what went wrong and how to fix it quickly. Automatically apply any eligible promo codes to skip the frustrating search. Tailor the experience by showing prices in local currency and surfacing familiar payment methods first. 

To significantly increase conversion rate, you need to prominently display in the cart with clear wording like “Free shipping, no minimum needed.” 

Highlight the savings with friendly microcopy such as “Normally $8.99 to your area, today it’s free.” A subtle animation like “You’ve unlocked free shipping!” adds a small moment of delight that justifies the purchase without feeling pushy.

eCommerce brand Rheal Superfoods takes this approach to “visually reward” subscription buyers within the cart itself, so that they can keep moving towards checkout:

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. 

Small shifts and tweaks have proven to improve eCommerce conversion rates. Strong calls-to-action do more than prompt a click, and they remove doubt across the journey. 

Adding reassuring microcopy next to the button, such as “Easy returns, hassle-free refunds,” quietly dissolves hesitation and makes the next move feel safe.

Combine CTAs with visible progress indicators, like numbered steps or progress bars, so shoppers clearly see how close they are to their goal. This clarity turns vague actions into confident progress.

Shift from generic text like “Add to Cart” to benefit-driven language that paints a vivid future: “Declutter My Home” for organizing tools or “Glow Up My Skin” for skincare.

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 without sacrificing margins.

16. Use Authentic Urgency Tactics

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

Urgency only works when it feels real and helpful, not forced. Single countdowns or stock alerts often come across as manipulative and push people away. 

Combine inventory cues like “Only 7 left in stock” with demand signals such as “15 people added this to their cart in the past hour.” 

Tie urgency to believable real-world limits: delivery cutoffs, seasonal deadlines, or restock dates. Avoid static timers that repeat on every visit, since familiarity quickly erodes credibility.

Place discounts where commitment is already strong, like cart abandonment offers in the cart or checkout, threshold-based free shipping on product pages, or loyalty perks for returning users. 

Reveal urgency gradually down the funnel: broad popularity early (“One of our top 3 sellers”), higher demand after adding to cart (“This item is moving fast right now”), and real-time cues on return visits. Anchor everything to external moments like holiday shipping deadlines or flash sale windows so it feels natural rather than salesy.

17. Smart Pricing Strategies to Increase Average Order Value

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

Shoppers often compare options in their heads, so smart pricing strategies can guide them toward yes without feeling pushy. 

When someone spends time browsing premium items, anchor your mid-tier product against those higher prices: “30% less than the designer version you viewed.” This subtle comparison makes your offer feel like a savvy choice and helps improve eCommerce conversion rate by reframing value instantly.

Move past generic sales with context that resonates: pre-holiday “last production run” pricing, end-of-season “clearing inventory space,” or “winter shipping window closing” for international orders. These reasons feel real and timely, creating gentle motivation to act now.

For products like tech, electronics, or home decor, use progressive value disclosure. Show the base price first to set expectations, then layer on additional value-adds, features, or upgrade options one by one.

PERSONALIZATION, RETENTION & LIFETIME VALUE

One of the most sustainable answers to how to increase conversion rate for eCommerce is making future buying decisions easier.

Through personalization, retention, and post-purchase improvements, brands can use eCommerce conversion rate optimization to continually improve conversion rates beyond the first sale.

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. 

True eCommerce conversion rate gains come from smoothing the entire path, not just one page. Personalize ads using real intent signals like visit frequency, pages viewed, deep engagement, or on-site searches. This brings shoppers back exactly where they left off instead of forcing them to restart.

Make product finder quizzes effortless: cap at five questions, stick to multiple-choice, and add brief tooltips explaining each step’s value. These quick tools cut decision fatigue and boost confidence fast.

Lean on zero-party data shoppers willingly share through quizzes or surveys. Use it to swap generic banners for tailored messages like “This week only: 15% off vegan bestsellers picked just for you.” 

Frame rewards around preferences, such as “You’re $150 away from a free eco-friendly tote,” keeping personalization relevant without crossing into creepy territory.

After the sale, extend the experience with helpful post-purchase emails: usage tips, how-to guides, and gentle review requests. Tailor retention offers to past behavior, like “Your dry-skin routine, save 15% on restock today.” Add growing loyalty perks such as early access or exclusive gifts to turn one-time buyers into loyal fans.

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.

A thoughtful post-purchase flow turns one-time shoppers into loyal customers by shortening the mental decision cycle for future purchases. This remains one of the most dependable ways to grow your eCommerce conversion rate over the long term.

Right after checkout, ease any lingering uncertainty with clear next steps and realistic delivery timelines. Swap bland confirmation pages for helpful guidance: quick how-to tips, setup instructions, or what to expect in the first few days of use. These small acts of care build immediate trust and satisfaction.

While the glow of a fresh purchase is strongest, gently introduce repeat-buy options like subscriptions, refills, or complementary items. 

Proactive updates on shipping progress, any delays, or arrival confirmations keep shoppers informed and prevent frustration from turning into support questions. 

When the entire experience feels supportive from start to finish, customers return more often and more confidently, helping you improve eCommerce conversion rates. 

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.

Sustainable eCommerce conversion rate growth comes from understanding what truly blocks shoppers from buying, not from chasing quick cosmetic fixes. 

Most tests fail because they tweak visuals without addressing real friction, bundle multiple changes into one test, or stop too early before patterns stabilize.

High-impact testing flips that approach. Begin with actual user behavior data from heatmaps, session recordings, or analytics, not assumptions. 

Focus experiments on moments of hesitation, uncertainty, or confusion, such as checkout doubts or unclear product details. 

After working on many eCommerce stores, we have noticed that changing only one major variable at a time can move the needle. Run tests long enough for behavior to settle into reliable patterns, even if it takes weeks.
