PPC — Pay-per-click advertising: PPC (pay-per-click) means you pay only when a shopper clicks your ad, not when it is shown. On Amazon, PPC covers Sponsored Products, Sponsored Brands and Sponsored Display. Managing PPC well — bids, keywords and negatives — is how sellers control ad cost and ACoS.

In depth

Pay-per-click is the billing model behind all Amazon Sponsored ads: you set a maximum bid per click and pay Amazon only when someone clicks. Good PPC management means bidding the right amount on the right searches and cutting the searches that waste money. Done by hand it is endless; it is the core of what ads-automation software does.

Formula

Ad Spend = Σ (Clicks × CPC) where CPC ≤ your Bid

Worked example

You launch a Sponsored Products campaign with a ₹15 default bid. Amazon shows your ad 20,000 times (impressions) and 400 shoppers click (CTR = 2%). Because Amazon's second-price auction charges just enough to beat the next bidder, your actual CPC averages ₹11.20 — not the ₹15 ceiling. Spend = 400 × ₹11.20 = ₹4,480. Of those 400 clicks, 32 convert into orders at ₹700 avg (conversion rate 8%), so ad revenue = ₹22,400 and ACoS = 4,480 ÷ 22,400 = 20%. The three levers you can pull next are bid, keyword mix, and negatives.

When to use it

PPC is the default framing for every Amazon Sponsored ad conversation — bids, budgets, negatives, keyword harvesting, dayparting. Use the term when talking to sellers or agencies used to Google/Meta; use "Sponsored Products/Brands/Display" when talking about the specific Amazon ad type.

Common mistakes

Bidding the same amount on every keyword — high-intent buyer keywords ("stainless steel water bottle 1 litre") can sustain 3× the bid of research keywords ("best water bottle"), and a flat bid overspends on the second and underspends on the first.
Never harvesting negative keywords — a single unmatched search term ("plastic water bottle" for a stainless-steel product) can burn 15–20% of a campaign's budget over a quarter with zero orders.
Setting a daily budget so low the campaign runs out by noon — you pay for morning clicks but miss the evening conversion peak that many categories rely on, silently inflating ACoS.
