Checkout Friction: The Small Frictions That Kill Conversions

Checkout friction is any effort, doubt or surprise between a full cart and a placed order that gives a shopper a reason to stop. It might be a field they have to fill in, a login they did not ask for, or a shipping fee that appears on the last screen. Each one looks minor on its own. Together they add up: Baymard Institute's (opens in a new tab) checkout benchmark found the average US checkout shows 23.48 form elements by default, where its testing suggests 12 to 14 can be enough. Friction works on people who already decided to buy, so removing it unblocks demand you already earned instead of trying to create new demand.

Effort, doubt and surprise

Telling the three kinds apart tells you where to look, and Baymard's survey of US online shoppers puts a number on each:

• Effort friction is work you make the shopper do: fields, steps, an account to create. 17% of shoppers in Baymard's survey left over a too long or complicated checkout, and 18% because the site wanted them to create an account.
• Doubt friction is a moment of hesitation, such as a payment page that looks unfinished or has no visible return policy. 19% said they didn't trust the site with their card details.
• Surprise friction changes the deal late. 40% left over extra costs such as shipping, tax and fees, and 12% because they couldn't see or work out the total up front.

Those shares exclude shoppers who were just browsing. They also overlap, which is the point: friction stacks. A shopper who would have put up with a long form leaves when a surprise fee lands on top of it.

Count your form fields

Effort is the easiest friction to measure, because you can count it. Baymard's benchmark counted 14.88 form fields in the average US checkout, out of 23.48 form elements shown in total. Its testing suggests an ideal flow can be as short as 7 or 8 fields, and that most checkouts could show 20% to 60% fewer elements by default.

Go through your own checkout and count what shows before anyone clicks. Then question the usual suspects: a second address line shown open by default, a company-name field shown to shoppers who are not companies, a "confirm email" box, a phone number you never call. Each one is a few seconds of work for a shopper who is about to hand you money.

Some friction is there on purpose

Not every step that slows a shopper down is a mistake. A card verification screen from the bank, an address check that catches a typo before the parcel ships, and an age check on restricted products all add effort. They also prevent fraud, a lost parcel or an order you cannot legally ship. Strip them out and the cost shows up later, as chargebacks and returned parcels instead of abandoned carts.

The judgment is telling friction that protects the order from friction that only protects habit, and it is not always clear. A phone number field is pure effort on most orders and a real need when the courier will not deliver without one. That call depends on your carrier, your products and your fraud rate, and no checklist makes it for you.

Find the worst source, then stop

Friction audits go wrong when they turn into a list of fifty tweaks. Usually one source is doing most of the damage, and the rest are noise next to it. In the Gate's worked sample, a flow called Mobile express lane scores 1 out of 2 on five of its seven signals. The Gate reads it LEAKING and names checkout simplicity as the fix to make first, with the note to cut steps and fields and add autofill.

Pairs well with

Friction starts before checkout. The AI Offer & Landing-Page Conversion Kit ($79) scores a landing page on clarity, proof, relevance, friction and honesty, and its claim linter returns Launch, Tune or Rework. If social is where shoppers find you, the Instagram Profile Conversion Audit ($79) scores a profile on six surfaces and, where one falls short, names the thing to fix first. For shoppers who leave anyway, the Cart-Recovery Sequence Effectiveness Gate ($49) grades the follow-up email flow.
