Cart Abandonment
What cart abandonment is, how to measure it, the usual reasons shoppers leave, and how to reduce and recover abandoned carts within Canadian law.
What Is Cart Abandonment?
Cart abandonment happens when a shopper adds products to an online shopping cart but leaves without completing the purchase. The cart abandonment rate is usually calculated as one minus the number of completed orders divided by the number of carts created, over the same period.
Some abandonment is normal and harmless: people use carts to compare prices, save items for later or check shipping costs. The goal is not to eliminate it but to find the avoidable causes, such as surprise costs, forced account creation, errors or a slow payment step, and fix them. Abandonment at the cart stage and abandonment once checkout has started are worth tracking separately, because they usually have different causes.
Why Cart Abandonment Matters
Abandoned carts represent shoppers who were close to buying, which makes them the clearest signal of friction in your store.
- Diagnostic value: Where people drop off, and on which devices, points directly to the problem, whether that is a shipping calculator, a form field or a payment error.
- Recoverable revenue: Unlike visitors who never engaged, cart abandoners have shown intent and can sometimes be brought back with a well-timed reminder.
- Acquisition efficiency: Every abandoned cart represents ad spend and SEO effort that reached the right person but did not convert.
- Product and pricing insight: Repeated abandonment on specific products or shipping zones can reveal pricing, stock or delivery issues.
Common Causes of Cart Abandonment
- Unexpected costs: Shipping, duties, taxes or fees that only appear at the last step.
- Forced account creation: Requiring a password before a first purchase.
- A long or confusing checkout: Too many fields, unclear errors or a layout that breaks on mobile.
- Payment problems: A preferred method is missing, a card is declined without a clear reason, or the payment step feels untrustworthy.
- Delivery doubts: No clear delivery date, limited shipping options or a vague return policy.
- Slow or broken pages: Cart or checkout pages that load slowly, time out or throw errors under real traffic.
Common Cart Abandonment Mistakes
- Measuring only the overall rate: Without a funnel broken down by step and device, you cannot tell which fix will help.
- Sending recovery emails without consent: Abandoned cart emails are commercial electronic messages under Canada's Anti-Spam Legislation (CASL), so you need appropriate consent and an unsubscribe option.
- Leading with discounts: Offering a coupon in every reminder trains customers to abandon on purpose and erodes margins.
- Hiding shipping costs: Delaying the shipping total to keep the cart price looking low simply moves the abandonment to the next step.
- Not testing on real devices: Problems with autofill, wallets or keyboards on phones are invisible on a desktop browser.
Best Practices for Reducing Cart Abandonment
- Show costs early: Provide a shipping estimate on the cart page and state free-shipping thresholds and duty handling clearly, especially for cross-border orders.
- Offer guest checkout: Let customers create an account after the order, using the details they have already entered.
- Streamline the form: Remove optional fields, use address autocomplete and correct
autocompleteattributes, and support digital wallets. Our checkout process entry goes deeper. - Build a consent-based recovery sequence: Capture email early in checkout with clear consent language, then send one or two helpful reminders with the cart contents and a direct link back.
- Instrument the funnel: Track cart, checkout-start, shipping, payment and purchase events in analytics, and review drop-off by device monthly.
- Keep it fast: Cart and checkout pages are dynamic and uncached, so efficient hosting and lean plugins matter here more than anywhere else.
Cart Abandonment at PerfectPixels
When we audit or build an online store, we set up funnel tracking so abandonment can be measured step by step, then fix the specific causes we find: cost transparency, form friction, payment options, mobile usability and performance. Where clients want recovery emails, we set them up with CASL-aware consent capture. This is part of our eCommerce work on WooCommerce and custom platforms.
Frequently Asked Questions
What is a normal cart abandonment rate?
There is no single right number, because rates vary widely by industry, price point and device, and different tools count carts differently. The most useful benchmark is your own store over time: measure consistently, make one change, and compare.
Are abandoned cart emails legal in Canada?
They can be, but CASL treats them as commercial messages, so you need express or implied consent, sender identification and a working unsubscribe mechanism. Collect consent clearly at the point you capture the email, and get legal advice if you are unsure how CASL applies to your situation.
Should I offer a discount to recover abandoned carts?
Use discounts sparingly. A plain reminder that restores the cart often works on its own, and fixing the underlying friction lasts longer than any coupon. If you test an incentive, limit it to a later reminder rather than the first.
