Most conversion problems aren't the result of one dramatic design flaw — they're an accumulation of small friction points, each one giving a hesitant customer a reason to leave rather than buy. Here are the ones we see most often.
1. Hiding Shipping Costs Until the Last Checkout Step
Unexpected costs at the final step are one of the single biggest drivers of cart abandonment. Show shipping estimates on the product or cart page, not as a surprise three steps into checkout.
2. Forcing Account Creation Before Purchase
Requiring an account before checkout adds friction at the exact moment someone has already decided to buy. Offer guest checkout, and invite account creation after the order is placed, when it's a lower-stakes ask.
3. Weak or Missing Product Search
A search bar that can't handle typos, synonyms or plural/singular variations sends customers straight to a “no results” dead end — and most won't retry with different phrasing. This matters most on larger catalogs, as covered in how to build an e-commerce website that converts.
4. Product Photography That Doesn't Answer Real Questions
A single studio shot rarely tells a customer what they actually need to know — scale, texture, how it looks in use. Multiple angles, lifestyle context and (where relevant) short video meaningfully reduce purchase hesitation.
5. No Visible Return Policy
Return policy is a trust signal, not just operational fine print. Burying it in a footer link makes hesitant buyers assume the worst. Surface a short, clear summary near the add-to-cart button.
6. Slow, Janky Mobile Filtering
Filter panels that require excessive scrolling or reload the entire page on every tap actively discourage narrowing down a large catalog on mobile — where, for most stores, the majority of sessions happen.
- Use a slide-in filter panel instead of a full page reload
- Show result counts before applying a filter, not after
- Keep active filters visible and easy to clear
7. Autoplaying Video or Sound
Autoplaying media with sound is one of the fastest ways to make someone bounce, especially on mobile in a public setting. If video adds value, let people opt in.
8. Cart Icons With No Feedback
When “add to cart” gives no visible confirmation, customers often click multiple times unsure if it worked — or worse, assume it didn't and leave. A brief, clear confirmation state removes that doubt.
9. Checkout Forms That Don't Explain Errors Clearly
A red border with no explanation forces the customer to guess what's wrong. Specific, inline error messages (“enter a valid postal code”) keep people moving instead of stalling out.
10. Treating Mobile as an Afterthought
This is the mistake underneath most of the others. If a store is designed on a large desktop monitor and only checked on mobile at the end, it will always feel like a compromise rather than a considered experience for the majority of visitors.
