10 common mistakes new ecommerce merchants make (and how to fix it)
- Most mistakes that sink new ecommerce stores are avoidable — and nearly all of them fall into a handful of recurring patterns.
- The biggest killers are: ignoring mobile, weak product photos, no email list, a complicated checkout, and no analytics from day one.
- You do not need to fix everything at once — prioritize the issues directly costing you sales right now, then work through the rest systematically.
- Building good habits early (tracking data, collecting emails, optimizing for mobile) is far easier than retrofitting them into an established store.
Starting an online store is exciting—but without the right focus, simple missteps can cost you time, money, and momentum. This guide highlights 10 of the most common mistakes new e-commerce merchants encounter, with practical examples and actionable fixes you can apply today to boost conversions, improve customer experience, and grow revenue.
Quick navigation
Mistake 1: Ignoring mobile optimization (and a clunky checkout)
What goes wrong
Today, a large share of online shopping happens on mobile devices. If your site isn’t fully responsive, calls-to-action are hard to tap, product images don’t render correctly, and checkout forms require zooming or scrolling. A slow, non-mobile-friendly checkout is one of the surest ways to lose a potential sale.
How to fix
Use a responsive theme or framework that adapts to any screen size.
Minimize page weight, optimize images, and enable lazy loading for faster performance.
Design a streamlined mobile checkout: large buttons, autofill support, and a guest checkout option.
Test checkout flows on multiple devices and browsers, and monitor speed with a performance tool.
Example
BrightWave Co. found that 62% of its traffic came from mobile in Q1, yet their checkout took three steps and required creating an account. After implementing a single-page, guest checkout and pixel-perfect mobile layout, mobile conversions rose by 28% in 60 days.
Mistake 2: Weak product photography and descriptions
What goes wrong
Product pages with blurry photos, missing angles, and vague descriptions leave customers guessing. Without clear visuals and benefits, shoppers struggle to imagine owning and using the product.
How to fix
Capture high-quality, high-resolution images with multiple angles and lifestyle shots.
Include a concise, benefit-driven description that answers: what it is, who it’s for, why it’s valuable, and how to use it.
Add size charts, color options, and material details. Use alt text to boost accessibility and SEO.
Incorporate short product videos or 360-degree views when possible.
Example
GlowLamp’s product page relied on a single product shot and a long block of text. After adding 5+ product photos, a short video demonstrating setup, and a clear spec table, they saw a 44% increase in add-to-cart rate.
Mistake 3: Underpricing or inconsistent pricing
What goes wrong
Pricing that seems arbitrary or constantly shifting erodes trust and margins. Underpricing can devalue your brand, while frequent price changes confuse customers and trigger more refunds.
How to fix
Develop a clear pricing strategy: cost-plus, value-based, or competitive benchmarking.
Maintain consistency across channels and update prices with a documented schedule (seasonal promos, not random changes).
Use psychological pricing (ending prices with .99 or .95) only where it fits your brand and tested results support it.
Example
NovaHome, a home goods store, kept discounting items almost weekly, which reduced perceived value and trained customers to wait for sales. After establishing a quarterly pricing calendar and anchor sale events, average order value (AOV) improved and checkout abandonment declined.
Mistake 4: Not building an email list
What goes wrong
Relying solely on paid traffic and social reach means missing a reliable, owned channel. If a platform changes rules or traffic drops, you lose access to customers or audience data.
How to fix
Offer an enticing lead magnet (discount, guide, or exclusive content) to capture emails.
Place opt-in forms on high-visibility pages: homepage, product pages, and checkout success pages.
Set up welcome emails, onboarding sequences, and cart-abandonment reminders with clear value.
Example
ShopBolt launched a 10-page buyer’s guide and a 15% off welcome email. Within 90 days, their email list grew by 38%, and returning customers increased from 18% to 28% of revenue.
Mistake 5: Overcomplicating the checkout process
What goes wrong
Long forms, mandatory account creation, or unexpected shipping costs at the final step trigger cart abandonment. shoppers expect speed and clarity at checkout.
How to fix
Offer guest checkout and progressive disclosure (show only essential fields upfront).
Auto-fill, saved addresses, and transparent shipping costs and timelines.
Provide clear progress indicators and allow payment methods customers already trust (Apple Pay, Google Pay, PayPal).
Example
ZenLine Electronics removed mandatory account creation and added a one-page checkout. They also displayed shipping costs earlier in the process. Abandoned carts dropped by 21% within a month.
Mistake 6: Poor SEO and missing content optimization
What goes wrong
Product pages that avoid keywords, structured data, and helpful FAQs miss organic traffic opportunities. Without proper SEO, new customers struggle to discover your products.
How to fix
Optimize product titles, meta descriptions, and image alt text with relevant keywords.
Use structured data (schema.org) for product information, reviews, and pricing.
Publish helpful content like buying guides, FAQs, and size/color/style comparisons that align with user intent.
Example
CosmoKits optimized product titles and added FAQ sections per item. Organic traffic to their top product pages increased by 52% over two months, with higher on-page engagement and lower return rates.
Mistake 7: Inadequate shipping, returns, and policies
What goes wrong
Unclear or expensive shipping options, long delivery times, and strict return policies create friction and distrust. Customers want transparent costs, reliable timelines, and easy returns.
How to fix
Offer clear shipping options, estimated delivery dates, and free shipping thresholds if possible.
Publish a straightforward, customer-friendly returns policy and provide a simple returns process.
Communicate order updates via email or SMS and offer easy tracking links.
Example
NovaWard Furniture started offering free shipping on orders over a certain amount and introduced a 30-day no-hassle returns window. Within three months, carts where shipping was a factor dropped by 27%, and refund requests decreased as expectations were managed upfront.
Mistake 8: Ignoring analytics and conversion-rate optimization
What goes wrong
Without data-driven insights, you guess what works. This leads to missed opportunities to improve layouts, copy, and offers that actually move the needle.
How to fix
Install analytics and e-commerce tracking (conversions, funnel steps, average order value).
Set up goals like newsletter signups, add-to-cart, and completed purchases to measure progress.
Run small, frequent A/B tests on headlines, CTAs, images, and price points.
Example
PulseGear tracked its checkout funnel and found a bottleneck at the payment step. By simplifying the payment options and adding a trust badge near the final CTA, they improved checkout completion by 18% in 6 weeks.
Mistake 9: Bad inventory and fulfillment management
What goes wrong
Stockouts, backorders, or misaligned supplier lead times ruin customer experience and hurt reputation. Inaccurate inventory data also makes it hard to plan campaigns and allocate cash flow.
How to fix
Use inventory management software and integrated order forecasting to align stock with demand.
Maintain minimum stock levels for fast-moving items and communicate lead times clearly.
Set up reliable supplier relationships and backup options to avoid disruptions. If you're dropshipping, read our tips for building a profitable business.
Example
TrailGoods struggled with frequent stockouts on its best-selling hiking backpacks. After adopting a simple inventory dashboard and lead-time forecasting, they cut stockouts by 40% and improved fulfillment speed during peak seasons.
Mistake 10: Not communicating brand story and trust signals
What goes wrong
Shoppers instinctively look for brands they can trust. A lack of storytelling, customer reviews, and security cues can make a new store feel impersonal or risky.
How to fix
Share a compelling brand story on your About page and weave it into product pages.
Show genuine customer reviews, photos, and video testimonials where possible.
Display trust badges, clear privacy policies, and transparent contact information.
Example
ElementalWear launched an authentic brand narrative and a reviews section with customer photos. The store saw a 22% lift in conversion rate and a 12% reduction in product return requests, as buyers felt more confident about quality and fit.
