Amazon Placement Bid Adjustments: 2026 Guide With Examples

Placement adjustments are the cheapest lever in Amazon PPC to get wrong. One percentage, set once, quietly multiplies every bid in a campaign for months.

This guide covers every Amazon placement as it works in October 2026, which ones take an adjustment, how adjustments stack with bidding strategies and bid rules, and how we turn a placement report into an adjustment percentage.

What Are Amazon Placement Bid Adjustments?

Amazon placement bid adjustments (also called placement bid modifiers) are campaign-level percentages that raise your keyword and product target bids when your ad is eligible for a specific spot, such as the top row of search results. You keep one base bid per target; the adjustment decides how much more you will pay where it converts better.

Amazon's Sponsored Products bid adjustment page, updated September 28, 2026, lists four placements you can adjust and allows up to 900% each. The adjustment "works in addition to your selected bidding strategy", so it stacks with dynamic bidding rather than replacing it.

The arithmetic is simple. A $1.00 bid with a 50% top of search adjustment bids $1.50 when it competes for top of search, and $1.00 everywhere else.

Sponsored Products Placements in 2026

Sponsored Products shows in more places than it did when we first wrote this post in 2023. Four placements take an adjustment; the newer surfaces don't.

1. Top of Search

Top of search is the top row of the first results page: up to five ads on desktop and four on mobile, per Amazon's definition. It usually has the highest click-through rate, conversion rate and cost per click (CPC) in the account.

It is also where most over-bidding happens, because "top of search converts best" is true often enough that people stop checking it.

2. Rest of Search

Rest of search covers the middle and bottom of page one and every page after it. Amazon added the rest of search adjustment in January 2024, also up to 900%, so all three on-Amazon placements can now be raised separately.

Rest of search inventory is large and usually cheaper. In the accounts we manage it is often the placement that sets the base bid, with the others adjusted from there.

3. Product Pages

Product pages are the ad slots on detail pages, including competitors' pages and your own, plus non-search placements such as the add-to-cart page. Click-through rates are lower, but product targeting campaigns on close substitutes can convert well here.

4. Amazon Business

The Amazon Business adjustment is one percentage, up to 900%, that applies to every Sponsored Products placement shown to business buyers on Amazon Business. Amazon's API release notes say it can be set on its own or alongside the other three, in the US, CA, MX, DE, UK, FR, IT, ES, IN and JP.

Since October 31, 2025 you can also run Amazon Business exclusive campaigns that serve only to business buyers. If B2B orders are a real share of your sales, that separation is cleaner than one adjustment on a mixed campaign.

5. Off-Amazon Publishers and Creators

Sponsored Products has served on third-party sites and apps since 2023. From August 10, 2026, campaigns were also enrolled in creator placements at their existing bids and budgets, PPC Land reported from Amazon's support page.

The bidding rule matters most here: "Bid adjustments for Top of Search and Product Pages do not apply to off-Amazon placements." Your base bid and dynamic bidding still apply. The campaign setting Limit off-Amazon spend reduces this traffic; Increase reach is the default.

6. Alexa for Shopping and Prompts

In May 2026 Amazon brought Rufus and Alexa+ together as Alexa for Shopping. Amazon says existing sponsored ads campaigns are automatically eligible to serve there "without additional campaign setup".

There is no Alexa for Shopping placement adjustment. Prompts, the clickable questions that open those conversations, are managed in the prompts report, as our prompts guide explains.

One more variant: Sponsored Products campaigns that run across other retailers replace the Amazon Business adjustment with top of browse and rest of browse adjustments for category pages.

Sponsored Brands Placement Adjustments After June 15, 2026

Sponsored Brands placement adjustments changed twice in a year, and many accounts still carry settings from the old rules.

Until mid-2025, Sponsored Brands only let you adjust "placements other than top of search", up or down by as much as 99%. On June 17, 2025 Amazon introduced positive adjustments for top of search, up to 900%, and raised the rest of search limit from 99% to 900%.

Then Amazon standardized on increases only. Its API release notes say negative Sponsored Brands placement adjustments "will not be supported starting June 15th, 2026": existing campaigns keep running with their current settings, but no new negative adjustment is accepted.

In practice that changes the method. Where we used to cut "other placements" by 30% to protect a campaign that won on top of search, we now lower the base bid and raise top of search instead.

Two Sponsored Brands rules still apply. Amazon's Sponsored Brands bid adjustment page allows one audience adjustment per campaign, and placement and audience adjustments combine up to a 900% total increase.

Cost controls interact too: with an adjustment on, Amazon notes "your highest possible CPC will exceed your target cost control CPC." Our Sponsored Brands guide covers goals and audiences in depth.

Display ads (formerly Sponsored Display) have no placement adjustments; they optimize for the goal you pick. Display, Video and Audio campaigns (formerly DSP) use bid adjustments on the predicted value of an impression by supply type, environment, format, audience and location, which is how "Amazon DSP placements" are controlled.

How Placement Adjustments Stack With Bidding Strategies and Bid Rules

This is the part that costs money. A placement adjustment never acts alone: a bid rule may add to it, and the bidding strategy multiplies the result.

The order for Sponsored Products:

1. Add the placement adjustment and any schedule or event bid rule to the base bid.

2. Multiply by the audience boost, if the shopper is in a boosted audience.

3. Multiply by the bidding strategy: 1 for fixed and down only, up to 2 for dynamic up and down, up to 5 for rule-based bidding.

Amazon's bidding rules page gives the example we start every training with. A $1.00 bid with a +10% top of search adjustment and a +20% Monday rule bids $1.30 at the top of search on Mondays and $1.20 elsewhere. The two percentages add; they never multiply each other.

Then the strategy works on that $1.30. Amazon's bidding strategies page says up and down can raise a bid "by up to 100% for all placements", so the Monday top of search bid can reach $2.60.

Audience boosts work differently from rules: they apply to the placement-adjusted bid, so they compound. Amazon's bid adjustments overview, updated September 28, 2026, takes $1.00 with +50% top of search to $1.50, then a +60% audience boost to $2.40. Only the highest audience boost applies when a shopper is in several.

On our Monday example, a 60% audience boost gives $1.30 × 1.6 = $2.08 before the strategy, and up to $4.16 on up and down.

This is the formula we use for the worst case. Write each percentage as a decimal, so +10% is 0.10.

Max CPC = base bid × (1 + placement % + rule %) × (1 + audience %) × strategy multiplier

Three more details belong in the math. Each one changes the worst case:

• Rule-based bidding multiplies the adjustment too. Amazon's own table caps a $1.00 bid with +10% top of search at $5.50, not $5.00. Schedule bid rules go on hold while rule-based bidding is active.

• Sponsored Products video has its own adjustment, up to 900% in the US, which stacks with placement and audience boosts. Amazon's example takes $1.00 to $4.50.

• Off-Amazon clicks skip the placement step. They bid base × strategy, so a lower base bid with a higher top of search adjustment also trims what you pay off Amazon.

Our bidding strategies guide covers each strategy, and our guide to audience bid boosting covers the audience step.

How to Read the Placement Report in Unified Reporting

Unified reporting has been generally available since June 8, 2026, and the old Sponsored ads report pages go read-only on December 17 and retire on December 31, 2026. The placement report now lives there as a set of dimensions, not a report type.

1. Build the Report

In Amazon Ads Agent, click Reporting, then Create report. Pick Sponsored Products, then tick Campaign and Placement classification as dimensions, with Week as the time dimension.

Add impressions, clicks, total cost, purchases and sales. We also add CPC, conversion rate and ACOS (advertising cost of sales) so the comparison is in one table.

2. Use 30 to 60 Days, Minus the Last 7

Thirty days is the minimum for most campaigns; low-volume ones need sixty. Ignore the most recent seven days for any judgment, because Sponsored Products sales keep attributing for 7 days after the click for sellers and 14 for vendors.

3. Read Placement Rows Against Each Other

The campaign total is an average of placements that behave very differently. Compare each row's CPC, conversion rate and ACOS with the campaign's target, not with each other's totals.

4. Check the Rows the Console Doesn't Show

Off-Amazon traffic appears as its own row; check it on every campaign since August. The Amazon Business placement report isn't in unified reporting yet, per Amazon's migration page, so download it from the legacy page before December 31.

For a quick look, the campaign's Bid adjustments tab in campaign manager shows placement metrics too. Our Amazon advertising reports guide covers the builder and the migration in full.

Worked Example: From Placement ACOS to Adjustment %

Here is the campaign from the report above, on dynamic bids down only with a 30% target ACOS and no adjustments yet. The numbers are illustrative.

At 25.6% against a 30% target, the campaign looks healthy, and most people would leave it. The placements tell a different story.

1. Find Each Placement's Headroom

Divide the target ACOS by each placement's ACOS. That ratio is how much more (or less) a click could cost at the same conversion rate before the placement hits target.

• Top of search: 30 ÷ 20 = 1.50, room to pay up to 50% more.

• Rest of search: 30 ÷ 33 = 0.91, about 9% too expensive.

• Product pages: 30 ÷ 40 = 0.75, 25% too expensive.

2. Set the Base Bid From the Weakest Placement You Want to Keep

Sponsored Products adjustments only go up, so the base bid has to carry the cuts. We lower it 10%, which brings rest of search close to target.

3. Raise the Placement That Has Room

To pay 1.5 times the old bid at top of search on a base 0.9 times as high, the full adjustment would be 1.5 ÷ 0.9 − 1 = +67%. We set +50% as a first step, so top of search bids 0.9 × 1.5 = 1.35 times what it did.

4. Deal With What the Adjustment Can't Fix

Product pages still bid 0.9 times against a 0.75 ratio. If product page spend matters, move the converting product targets into their own campaign, where a lower base bid applies only to them. Our campaign structure guide shows that split.

5. Re-Read in Two Weeks

Higher bids buy more top of search impressions at a higher CPC, and conversion rate rarely holds perfectly. Re-run the report after 14 days of settled data and move the adjustment again only if the ratio still says so.

We cap each step at about 30% to 50% for the same reason: the ratio tells you the direction and the ceiling, not where the auction will settle.

Top-of-Search Impression Share: When to Chase It

Top-of-search impression share is the percentage of top of search impressions a campaign received out of those it was eligible for. Amazon launched it in 2021 for Sponsored Products and Sponsored Brands with a 90-day lookback, and names placement adjustments as the way to raise it.

In unified reporting it is campaign level only; legacy reports also had it by keyword and target. For keyword-level share, the Search Term Impression Share report shows your share and rank on each term.

Our rule of thumb, from the accounts we manage:

• Low share, ACOS under target: the placement is profitable and underbid. Raise the adjustment in steps.

• High share, ACOS under target: you already win most auctions you're eligible for. Extra bid mostly raises CPC.

• ACOS over target: lower the adjustment whatever the share, unless the campaign has a non-ACOS job such as brand defense.

Impression share also tells you about competitors. A sudden drop on a hero campaign with no change on your side usually means someone outbid you, which share of voice tracking shows by keyword and hour.

Placement Adjustments by Campaign Type

The same adjustment means different things in different campaigns, so we never copy one setting across an account.

For event days, raise top of search on proven campaigns a few days early and set a calendar reminder to bring it back. Our Q4 playbook covers the timing, and dayparting can shift placement adjustments by hour where the console can't.

Auction Pricing and What You Actually Pay

A placement adjustment raises your maximum bid, not necessarily your CPC. Amazon's auction help page says reserve prices can lift the final price based on predicted performance, competing bids, placement and peak periods, and that "the price charged to you may exceed the runner-up bid but will never exceed the maximum bid you authorize."

On August 31, 2026, the FTC and 22 states sued Amazon, alleging its sponsored ads auctions, presented as second-price, used a hidden "soft reserve" that raised costs. These are allegations Amazon disputes; in a statement reported by Bloomberg, it said it properly describes its pricing and auctions. The case is pending.

For placement work the lesson is practical. Treat the stacked maximum as a price you may pay in full, and set adjustments so that price still clears your target.

What Changed in Placement Bidding in 2025 and 2026

Mistakes We See in Placement Audits

• Adjustments with no report behind them. A +100% top of search setting "because top converts" is the most common one we find in a PPC audit.

• Forgetting the strategy multiplier. A $1.00 bid with +100% top of search on up and down can cost $4.00 at the top of search.

• Multiplying a bid rule by a placement adjustment. They add. A +10% placement and a +20% rule are +30%, not +32%.

• Event adjustments left on. Adjustments never expire; we still find Black Friday +200% settings running in February.

• Judging on the campaign average. A 25.6% campaign can hide a 40% placement, as in the example above.

• Assuming off-Amazon follows top of search. Creator and publisher clicks bid at base × strategy and need their own check.

• Waiting for negative Sponsored Brands adjustments to come back. They won't; restructure with base bids.

How We Manage Placements in Adbrew

Everything above works in the Amazon Ads console, campaign by campaign. Across hundreds of campaigns and several ad types, the reading and the arithmetic take most of a week.

Adbrew is an agentic retail media management platform for Amazon and Walmart, and placement management is one part of it:

• Placement data next to the decision. Placement performance sits beside each campaign in Sponsored Ads management, with the target ACOS you set, so the headroom ratio is visible without a spreadsheet.

• Rules you set for bids, budgets and placements. You choose the target, lookback, minimum clicks and step size, and every rule reads in plain language. Automated audits flag rules that conflict, such as two rules raising the same campaign.

• Bulk changes. Reset placement adjustments or change bidding strategies across a portfolio in one action, as our bulk operations guide describes.

• Hourly schedules. Amazon Marketing Stream data powers dayparting grids that work for placements as well as bids and budgets.

• Adbrew Intelligence and MCP. Ask "which campaigns have top of search under target ACOS and impression share below 30%?" and get the list, or have the agent draft adjustment changes that apply only after you approve them.

Every change lands in Change History with the rule or person that made it. Brands on Adbrew cut ACOS by 46% on average.

Set Placements From the Report, Not From Habit

Good placement bidding is one ratio per row, read every two weeks, and an honest look at what the strategy multiplies on top.
