Being a Shopify store owner comes with both thrills and challenges. Did you know there are a few overlooked aspects of running a Shopify store that can negatively impact sales?
These issues can include a slow loading page and incorrect inventory control.
In this post, you will learn 10 common Shopify mistakes we often come across when working with Shopify store owners.
Here they are, in no particular order of importance:
1. Not Optimizing Your Shopify Site Speed
Why Speed Matters for Your Shopify Store
Speed decides whether a visitor becomes a customer before they've read a single word. In our benchmark of 1,000 Shopify stores, only 48% passed Core Web Vitals on mobile. That means more than half the stores we looked at are losing rankings and sales to a slow experience without knowing it.
Slow loading doesn't just frustrate shoppers, it can also hurt your SEO rankings, making it harder for customers to find you at all.
How to Improve Your Shopify Store Speed
Improving speed starts with optimizing the basics.
- Optimize Your Images: Large images tend to be the main cause of slow loading times on your website. Use tools like TinyPNG to shrink your images without losing quality.
- Choose a Lightweight Theme: Heavier themes look appealing, but they slow things down. Select one that’s optimized for speed.
- Limit Third-Party Apps: Too many apps installed on your store create additional code that slows down operations.
- Enable Lazy Loading: Images on your website should load as users scroll to them because this practice reduces initial page loading time. Lazy loading is one of the main methods of optimizing your Shopify store speed.
-
Upgrade Your Shopify Plan: Your store will benefit from increased speed with a higher-tier Shopify plan (e.g. Advanced or Plus)
Taking these steps can significantly improve your customer experience and, ultimately, your conversion rates.
2. Failing to Set Up Payment Gateways Correctly
Common Payment Gateway Issues
Payment gateways are the backbone of your store's transaction system. If a customer's preferred payment method is missing at checkout, they abandon the cart. Most of them do not come back to finish it later.
There is a clear minimum bar here now, and it has moved. Shop Pay is the baseline. Shop Pay plus Apple Pay plus Google Pay is best practice. If you are still only offering credit card and PayPal, you are behind what your customers already expect from every other store they buy from.
Understanding Shopify Pricing matters here too, since transaction fees and payment gateway costs affect your margins on every order. Head to our Shopify price calculator to calculate the full costs.
Tips on setting up Shopify Payment Gateways
-
Enable Shop Pay, Apple Pay, and Google Pay: These express options let a returning shopper check out in one tap. Without them, every purchase forces someone to type out card details again.
-
Test the full checkout after every theme or app update: A broken gateway rarely announces itself. It shows up days later as a quiet drop in completed orders.
-
Add multi-currency support if you sell internationally: A customer converting prices in their head is a customer getting closer to leaving.
- Count your own checkout steps: In our audit framework, we flag anything past 3 steps as friction worth investigating. Walk through your own checkout as a first-time buyer would and see where it drags.
3. Not Using Shopify Analytics Effectively
The Backend Problems Analytics Usually Hides
You're making decisions on gut feeling if you're not looking at your data, and gut feeling gets more expensive as your store grows. Shopify Analytics gives you the insights to understand customer behavior, track sales performance, and catch problems before they cost you money.
The backend is where most of this breaks quietly.
In our own audits, 14 out of the last 20 stores we reviewed had at least one stale user account with full admin access left over from an old agency or contractor. Eight had duplicate GA4 tracking codes, which means purchases get counted twice and your paid media optimizes against numbers that were never real.
|
What to check |
Where to look |
Risk if ignored |
|
Add to Cart, Begin Checkout, Purchase events firing |
GA4 DebugView while walking your store live |
Funnel data is wrong before you've analyzed anything |
|
Stale user accounts |
Settings > Users and Permissions |
Former agency or contractor retains access to customer data |
|
Duplicate GA4 tracking codes |
One GA4 property, one pixel per platform |
Sessions and purchases inflated, ROAS calculations wrong |
|
Shopify and GA4 time zone match |
Admin > Property Settings > Property Details |
Daily revenue figures never reconcile between platforms |
4. Ignoring Mobile Optimization
Mobile Is Still an Afterthought for Most Shopify Stores
According to the data, more than 60% of online shopping takes place through mobile devices. As a result, if your store is not mobile optimized you are missing out on a significant number of potential customers.
Mobile is where most Shopify stores fail to pass core vital
How to Make Your Shopify Store Mobile-Friendly
Making your store mobile-friendly doesn’t have to be complicated.
- Use a Responsive Theme: This guarantees that your store changes its layout in accordance with the screen dimension of the user.
- Optimize Images and Videos: Mobile users don’t have time to wait for slow-loading images, so compress them for quicker loading times.
- Simplify Navigation: Large buttons and a simple menu are crucial when navigating through a mobile application.
- Test the Mobile Checkout Process: Make it a thorough test of the entire process, from the beginning to the end, including the Shopify payments section.

Mobile optimization is no longer optional, it’s essential for maintaining a competitive edge, especially when using a Shopify app to enhance the shopping experience.
5. Not Using Effective Product Descriptions
Product Descriptions Matter More Than Ever
Your product descriptions should sell. If they're bland or generic, you're not doing enough to convince a customer to buy.
But there's a second reader now too: AI assistants scanning your page to decide whether it's worth citing when someone asks for a recommendation. Generic copy fails both readers for the same reason. It doesn't say anything specific to this product, on this store.
Example of a LLM optimized PDP from Cotopaxi and the citations it earned in chatGPT.
Our research on the effect of duplicated content across 1,000 Shopify stores found that 20% of product descriptions appear near-verbatim on another domain, and when we tracked what AI tools actually cite while answering real buying questions, only 2.8% of sources pointed back to the brand's own product page.
| What uncited stores do | What cited stores do |
|---|---|
| Reuse the supplier description across every sales channel |
Write a description unique to their own store |
| Copy the same text across sibling products | Give each product page passages an AI can quote |
| Answer buyer questions only in images or JavaScript | Put those answers in text, in the raw HTML |
| Leave the structured data description thin or empty | Fill structured data with real product copy |
One habit does more for this than any rewrite: state your key facts as a plain subject-verb-object sentence instead of burying them in a soft intro. "Our anchor system prevents trailer sway" is a fact a model can lift. "Sway, which many owners struggle with, can potentially be reduced" is the same fact drowned in noise.
Here's how we teach that structure in more depth, with a free skill you can run on your own pages.
One more thing worth knowing: agentic commerce isn't upcoming, it's already live. AI-driven traffic to Shopify stores grew 8x year over year in Q1 2026, and orders from AI-powered searches grew nearly 13x.
Buyers can now complete a purchase directly inside ChatGPT, Copilot, or Google's AI Mode without ever landing on your store. The fix is the same one from Block 5: specific, structured product data an AI agent can act on without guessing.
6. Poor Inventory Management
What Happens When Inventory Management Fails
Running out of stock costs you the sale in front of you. Overstocking a product nobody buys ties up cash you could be using somewhere else. Both mistakes are common, and both are usually caught too late.
In our own store audits, 3 of the last 20 stores we reviewed had inventory sync failures the merchant didn't know about until a customer complained. That is the real risk with inventory. It rarely announces itself. It shows up as an angry email about an order that can't be fulfilled.
How to Use Shopify to Manage Your Inventory Effectively
-
Set up automated low-stock alerts: Get notified before you run out, not after
-
Spot-check your SKUs against actual stock: If you sell across multiple channels, pick 3 to 4 SKUs and verify the numbers match. Sync between Shopify and a third-party channel can lag without warning.
-
Offer pre-orders on high-demand items: Let customers buy before restock instead of losing the sale entirely.
-
Use your sales history to predict demand: Past trends tell you more about what to reorder than a gut feeling does.
7. Overcomplicating the Checkout Process
Why a Complicated Checkout Can Hurt Your Sales
A long or confusing checkout process can cause customers to abandon their carts. The easier and faster it is to buy, the better your chances of closing the sale. Making the checkout process as seamless as possible, can reduce cart abandonment and improve conversions.
How to Simplify Your Shopify Checkout Process
- Enable Guest Checkout: Let customers buy without creating an account.
- Reduce Form Fields: Only ask for the essentials to speed up checkout.
-
Offer Express Checkout: Use options like Shopify Pay, Apple Pay, or Google Pay for one-click payments.
- Don't overuse badges: A few are enough, to many become a distraction
8. Leaving Upsell Revenue On The Table
The Benefits of Upselling and Cross-Selling for Your Shopify Store
These strategies increase your average order value by encouraging customers to buy more without acquiring new ones. For more tips and tools to optimize your sales, visit the Shopify website for Shopify experts resources and insights and if needed contact Shopify customer service.
How to Implement Effective Upselling and Cross-Selling on Shopify
- Suggest Higher-End Alternatives: Offer premium versions or related accessories when customers add items to their cart.
- Create Bundle Deals: Offer discounts for purchasing related products together.
- Recommend Complementary Products: Use Shopify’s apps or built-in features to show other relevant products to your customers.
Even details, such as the checkout progress bar can be used to upsell while helping users navigate the process.
9. Failing to Build Customer Trust
Why Trust Is Key to Converting Visitors into Customers
Building trust is essential for driving conversions. If customers don’t feel confident in your store, they won’t complete the purchase. To learn more about establishing credibility and boosting sales, check out guides on how to sell on Shopify for expert tips and best practices.
How to Build Trust on Your Shopify Store
- Display Verified Customer Reviews: Show potential customers that your products are high quality and that others are happy with their purchases.
- Use Security Badges: Display SSL encryption and payment security badges to reassure customers.
- Offer a Clear Return Policy: A straightforward return policy builds confidence and shows that you stand behind your products.
Building trust is a long-term investment in your store’s success.

10. Skipping Technical SEO
The 'boring' part is what sinks most stores
The part that quietly tanks rankings is broken links, missing alt text, and pages that return an error code Google can't index.
You can check pages that are not indexed in the Search Console as the first step on a basic SEO audit
A page returning a 4xx error tells search engines the content doesn't exist, and it gets dropped from results even if the product is still for sale. Broken internal and external links pile up fastest after a URL change, a theme migration, or a discontinued product, and most stores never go back to check.
Stores that win are the ones that stick to a checklist
-
Crawl your own site for broken links after any URL change, migration, or product removal. A tool like Ahrefs or Screaming Frog will surface every 4xx in minutes.
-
Add Product, Offer, and Review schema to your best-selling pages. This is what earns star ratings and price in search results, not just a ranking, and most Shopify themes don't add it by default.
-
Check your theme isn't generating missing or duplicate H1 tags. Some themes do this without you noticing, and it weakens the page's main topic signal to Google.
-
Fix redirect chains, not just broken links. A product that redirects three times before landing on its real page loses ranking signal at every hop.
