What is CVR?

CVR (conversion rate) in Amazon advertising is the share of ad clicks that end in an order. It decides what each click is worth, which makes it the rate that most directly sets how much you can afford to bid.

Definition

Amazon Ads defines conversion rate in general as conversions divided by the total audience, times 100 (Amazon Ads conversion rate guide, checked 2026-10-03). For sponsored ads the audience is the clicks and the conversion is the attributed order. Three details decide what the number means.

• Orders, not units. A shopper who buys three units in one order is one conversion. Order value carries the rest.
• Attributed, not observed. An order counts if it follows the click inside the ad type's attribution window, and it is credited to the day of the click. Attributed orders can include other products from your catalogue bought after the click.
• Ad clicks only. Unit session percentage in Business Reports covers every visit to the detail page, paid and organic. That is listing conversion rate, a different number with a different denominator.

Formula

CVR = Orders ÷ Clicks × 100
Clicks per order = 1 ÷ CVR

Worked example: derive your own target

There is no universal good conversion rate. There is the rate your own margin and click price require. Work out break-even ACoS first (the break-even ACoS calculator does this), then solve for conversion.

Example inputs, invented for round arithmetic: a product has an average order value of $30 and leaves $9 of contribution margin per order before advertising, so its break-even ACoS is 30%. Its keywords pay an average CPC of $0.80.

Break-even CVR = CPC ÷ (AOV × Break-even ACoS)
               = $0.80 ÷ ($30 × 30%)
               = $0.80 ÷ $9.00 = 8.9%

Read it the other way round. $9 of margin buys 11.25 clicks at $0.80. If it takes more clicks than that to win an order, which is any CVR below 8.9%, each order costs more in advertising than it earns. A target ACoS of 24% raises the bar to $0.80 ÷ ($30 × 24%) = 11.1%, or one order in every 9 clicks.

Now suppose a keyword on this product converts at 6%. There are two ways to reach break-even: lift conversion to 8.9% through the listing, or bring CPC down to $30 × 6% × 30% = $0.54 through the bid. The max CPC calculator runs that second calculation.

How to use CVR to make decisions

Treat it as the widest lever. ACoS equals CPC divided by CVR times order value. Holding CPC and order value fixed, doubling CVR halves ACoS, and the fixes live on your listing: price, main image, reviews, content and delivery promise.

Wait for enough clicks before judging. Example: if a keyword truly converted at 10%, the chance of zero orders in 15 clicks is 0.9 to the power of 15, about 21%, roughly one keyword in five. At 30 clicks it falls to about 4%. Zero orders on a handful of clicks is not evidence of a bad keyword.

Compare with the market on the same query. In Brand Analytics' Search Query Performance report, your conversion relative to the market's equals your purchase share divided by your click share. Example inputs: 4% of a query's clicks and 6% of its purchases means you convert at 1.5 times the market on that search, which makes it a query worth buying more of. The report counts organic and paid traffic together.

Read it by hour and by day. If conversion drops in some hours while CPC holds, revenue per click falls with it, and those hours deserve a lower bid rather than absence from the auction. The dayparting guide covers how to act on that.

Common mistakes

1. Copying a "good conversion rate" from someone else. Conversion depends on price, category, brand versus generic searches and placement. The target that matters is the break-even CVR built from your own margin and CPC, above.
2. Averaging rates. Example inputs: one keyword with 1 order from 10 clicks (10%) and another with 10 orders from 50 clicks (20%) convert at 11 ÷ 60 = 18.3% together, not the 15% their average suggests.
3. Judging the last few days. Orders keep arriving until the attribution window closes, so recent days understate CVR by construction.
4. Blending brand and generic traffic. Shoppers who searched for your brand convert differently from cold traffic. One blended rate describes neither audience.
5. Taking halo orders as proof. A keyword whose orders are mostly other products in your catalogue is not proven for the product it advertises. Check same SKU orders before scaling it.
6. Borrowing conversion from another product. A thin keyword priced on a different product line's conversion rate is a guess with a number attached.

How CVR relates to adjacent metrics

RPC  = CVR × AOV
ACoS = CPC ÷ (CVR × AOV)
CPA  = CPC ÷ CVR

Click-through rate decides how many clicks you get. CVR decides how many become orders, and average order value decides what each order is worth. Multiply CVR by order value and you have revenue per click, the number every bid should be built from. Amazon's Ads Math guide uses the cost per acquisition form, CPC divided by conversion rate, and says to link CPC to "conversion rate and profit per order" rather than judging it alone (Amazon Ads, Ads Math, checked 2026-10-03).

How Shurq helps

• CVR on every row. The /ad-manager grid shows CVR (orders divided by clicks) next to CPC and revenue per click from campaigns down to search terms, with the change against a comparison period when you set one.
• Bids priced on the next click. Shurq's bid optimizer prices a keyword on the conversion it expects next: the keyword's own clicks and orders, blended with how its product family converts, with the keyword taking over as its own orders arrive. It never borrows a different product line's conversion rate or an account average. A product with no record of its own holds and says so.
• Rank defense that reads conversion. On exact-match keywords where Shurq tracks your organic rank, a slipping position can earn a small raise, but a falling conversion rate stops it, because a slide the listing earned is not something more spend will fix.
• You against the market. The Search Query Performance funnel in Shurq sets your conversion rate beside the market's at every stage, from click-through to purchase.
• Conversion by hour. The dayparting scheduler charts conversion rate by time of day and day of week and proposes an hourly bid schedule for you to review. Nothing changes on Amazon until you apply it.
