Free CRO x AOV Profit Check — no store connection needed
The evidence, before the advice
Pulled 10 Aug 2026
What still works in CRO x AOV, and what quietly kills margin
Seven levers. For each one: the mechanism from the literature, the proof the market pays for it, and what named operators report happening on real stores. Two of them Okiela refuses to recommend at all. There is not one uplift percentage on this page — no app can predict a lift for your store, and pretending otherwise is how sellers get talked into losing money.
The order value where free shipping stops costing you money.
1
Discounts to lift conversion
Works on AOV, can lose money
The mechanism
A discount reliably raises conversion rate, which is why it is the most-reached-for lever. The mechanism was never in doubt; what is in doubt is whether the extra orders pay for the margin handed to the orders you already had.
What Okiela does about it: Computes your break-even discount before anything else, and ranks cutting a running discount as the first action — it needs no app and returns margin on the next order.
2
Star rating next to Add to Cart
Still works
The mechanism
Social proof. Purchase likelihood rises with the presence and quantity of reviews, with diminishing returns — and a credibility ceiling, because a perfect 5.0 reads as filtered.
What Okiela does about it: Ranks it first when the page scan proves no rating is visible near Add to Cart, and routes you to a genuinely free tier rather than a paid plan.
3
Free-shipping threshold
Works on AOV, can lose money
The mechanism
Mental accounting: an itemised shipping charge is booked by the buyer as a loss, so removing it is worth more than the cash it costs. The theory says nothing about where to set the number.
Hextom Free Shipping Bar, 4.9★ across 2,795 reviews, from $9/mo — and the same bar inside Vitals and Rebuy.

What happens on a real store
Buyers often just pay the shipping instead of adding product, and when they do add, they add the cheapest thing on the site. Two thresholds can win the same test on two different metrics.
“I was wrong. AOV barely moved. Customers didn't add more products... they were perfectly happy to pay for shipping. Shipping revenue rose 17.44% while free-shipping orders fell 11.40%.”
“It's pointless to make orders bigger if you're reducing profit — set the threshold from your real order-value cluster, and watch for buyers adding a sticker just to clear it.”
What Okiela does about it: Derives the threshold from your contribution per order and the shipping you actually pay, then states the profit-per-visitor consequence instead of the AOV consequence. Perkins's split is the exact fork Okiela exists to settle.
4
Quantity break and bundles
Works on AOV, can lose money
The mechanism
Decoy effect: a deliberately weaker tier makes the target tier look like the correct choice. The psychology is robust and entirely silent on cost.
Bundler 4.9★/2,498 and Frequently Bought Together 4.9★/1,030, plus a first-party bundle builder inside Replo and quantity-break guides from PageFly.

What happens on a real store
Blended bundle margin hides your worst SKU, bundle discounts stack with promo codes, returns are asymmetric, and 3PL pick-and-pack is billed per item — not per bundle.
“The bundle was the biggest revenue driver and was losing a bit more than $4 per bundle.”
What Okiela does about it: Gives every bundle a hard discount ceiling from your own unit economics, shows buyer saving and seller margin side by side, and names per-item fulfilment and discount stacking as the two things that break the ceiling.
5
Post-purchase / thank-you-page offer
Still works
The mechanism
The decision is already made and the payment friction is already paid, so the incremental offer carries no acquisition cost and cannot cost you a conversion.
ReConvert / Upsell.com 4.8★/2,782 and AfterSell 4.8★/884, with Zipify OCU shipping dedicated post-purchase and thank-you-page editors on Shopify checkout extensibility.

What happens on a real store
The one AOV lever that never touches the pre-purchase decision. Vendor-published take rates are unverifiable and are not repeated here.
“Post-purchase and thank-you-page offers are now built on Shopify's checkout extensibility.”
What Okiela does about it: States the floor price at which the offer still clears contribution, and refuses to state an expected take rate.
6
Countdown timers and low-stock counters
Dead — and now a liability
The mechanism
Scarcity used to work because buyers believed it. Reactance replaced it: once a deadline is read as a tactic, the buyer pushes back against being pushed.
Still sold by third-party apps, but the page builders have quietly de-emphasised it: seven mentions across their libraries against 83 for bundles, and no first-party block.

What happens on a real store
A resetting timer costs trust that never appears in your analytics, and the UK CMA has written to online businesses directly about urgency claims. The only surviving version holds real inventory for a real deadline — a fulfilment build, not an app toggle.
“It never shows up in GA4. It shows up later, when your promos start drawing more side-eye and your best customers slowly stop coming back.”
What Okiela does about it: Never recommends it. Where a scan finds a resetting timer, Okiela names it as a trust leak rather than an optimisation.
7
Exit-intent discount popup
Unproven
The mechanism
Loss aversion on a session about to leave. The counter-mechanism is a training effect: a reliable exit coupon teaches buyers to trigger it, turning full-price intent into discounted intent.
Shipped by every popup vendor and every builder. A ready-made block is evidence of demand for the surface, not evidence the economics work.

What happens on a real store
No store-level readout separating incremental orders from cannibalised full-price orders was found in this pass. Until one exists, it is a discount wearing a conversion costume.
What Okiela does about it: If you run one, Okiela measures it against your break-even discount like any other coupon — and says plainly that the incrementality question is open.
