Cart abandonment is usually a clarity problem, not a traffic problem. Here is a focused way to fix the biggest leaks first.

The average cart abandonment rate is still around 70.19%. Most teams read that number as a demand problem, but it is usually a decision problem.
By checkout, the buyer is already interested. They chose a product, selected a variant, and clicked add to cart. They leave when the final steps feel risky, expensive, or harder than expected.
Baymard's research shows the same pattern every year. People abandon because total cost appears too late, checkout forces account creation, or the flow feels long and complicated.
Those are fixable product decisions. They are not brand weakness and they are not ad quality issues. Every one of those reasons points to a moment where the buyer's confidence dropped below the threshold needed to finish.
Extra costs are the top reason for abandonment, with nearly half of buyers citing shipping, tax, or fees that appear too late.
The first fix is simple. Show expected shipping and tax earlier, ideally on the product page and in-cart. If the final price changes, explain why in plain language so the buyer feels informed, not trapped.
When cost is predictable from the start, buyers evaluate value instead of defending against risk. This single change often produces measurable lift because it removes the most common reason people walk away.
Around a quarter of abandoned carts happen because the site requires account creation before purchase.
Guest checkout is not a small UX tweak. It protects momentum at the highest intent moment in the journey. The buyer has already made their decision. Asking them to create a password and verify an email introduces effort that has nothing to do with the product they chose.
You can still ask for account creation after payment, when trust is already earned and the buyer has a reason to stay connected.
Long checkout flows increase abandonment because buyers start to question effort versus reward. Baymard also reports that 22% leave when checkout feels too long or complex.
You do not need a redesign to improve this. Remove nonessential fields, support browser autofill, and keep error handling clear and local so people do not lose progress. Each unnecessary form field is a small tax on the buyer's momentum, and those taxes add up quickly.
Cart reminders and retargeting can recover some lost orders, but recovery cannot outgrow a broken checkout.
When the core flow is clear, recovery works better because it reminds buyers who were genuinely distracted. They left because life interrupted them, not because something felt wrong. When the flow itself is unclear, recovery keeps sending people back into the same friction that pushed them away the first time.
Fix the experience before you scale the reminders.
Start with one high-volume product and run ten test checkouts on mobile and desktop. Track where costs first appear, where the form slows down, and where trust questions go unanswered.
Then ship improvements in this order: cost clarity, guest checkout, form reduction, and error handling. That sequence removes the largest hesitation points first and usually creates lift without touching acquisition spend.
Seventy percent abandonment sounds overwhelming until you break it into causes you can actually control.
When checkout feels predictable, easy, and safe, buyers finish what they already intended to do.
