Amazon Placement Bid Adjustments: Top of Search, Rest of Search, and Product Pages

Placement bid adjustments let you raise your Sponsored Products bids by a percentage for specific ad locations: top of search (first page), rest of search, and product pages. You can set each from 0% to 900%. The right way to use them is to check the placement report, find which placement converts most profitably, and increase only that one, while keeping your base bids set for the weaker placements.

Done well, placement adjustments are one of the cheapest ways to improve ACoS without touching keywords. Done carelessly, they quietly multiply your CPC. Here is how to get them right.

The three Sponsored Products placements

These patterns are common but not universal. Some products convert well on competitor detail pages, especially when they are cheaper or better reviewed than the product being viewed. That is why you set adjustments from your own report, not from a rule of thumb.

How placement adjustments are calculated

A placement adjustment multiplies your keyword or target bid when your ad is eligible for that placement. A 50% top-of-search adjustment on a $1.00 bid makes your bid $1.50 for that placement. The base bid still applies everywhere else.

Adjustments stack with your campaign bidding strategy. Under Dynamic bids - up and down, Amazon can raise the already-adjusted bid by up to 100% at the top of search and up to 50% on other placements. So a $1.00 bid with a 50% top-of-search adjustment can reach $3.00. Under down only, it caps at $1.50. Read Amazon bidding strategies explained before you combine the two.

How to read the placement report

1. In the Amazon Ads console, open a Sponsored Products campaign.
2. Go to the Placements tab. You will see impressions, clicks, spend, sales, ACoS, and orders broken out by placement.
3. Set a date range of at least 30 days, ending a few days ago, so attribution has caught up and you have enough clicks.
4. Compare ACoS and conversion rate across placements. Note CPC too, since the top of search usually costs more.
5. For an account-wide view, download the Sponsored Products placement report from the reporting section of the console.

Do not decide from a handful of clicks. As a rough threshold, wait until each placement you are comparing has at least 50 to 100 clicks before changing its adjustment.

Worked example: setting a top-of-search adjustment

Here is 30 days of placement data for an exact-match campaign with a $1.00 base bid and no adjustments. The target ACoS is 30% and the average order value is $30.

Top of search converts three times better than the other placements and is closest to target. The other two are well above target. The fix is a two-step move: lower the base bid so rest of search and product pages become profitable, then add a top-of-search adjustment so that placement keeps a competitive bid.

A quick way to estimate a profitable bid for each placement is: max CPC = average order value x conversion rate x target ACoS. For top of search: $30 x 12% x 30% = $1.08. For rest of search: $30 x 4% x 30% = $0.36. So you could work the base bid down toward about $0.40 and set a top-of-search adjustment of about 170% ($0.40 x 2.7 = $1.08). That keeps the strong placement competitive and stops overpaying on the weak ones.

Rules of thumb for each placement

Top of search

• Raise it when its ACoS is below target and its conversion rate is clearly higher than other placements.
• Start at 20 to 50% and increase in steps of 10 to 25 points.
• Use the top-of-search impression share metric to see whether you are actually winning that spot before raising further.

Rest of search

• Many campaigns leave this at 0% and let the base bid handle it.
• Increase it only if the report shows profitable conversions here, which can happen for long-tail keywords.

Product pages

• Useful for product targeting campaigns aimed at competitor ASINs where you have a price or rating advantage.
• If product page ACoS is far above target, lower the base bid rather than leaving a weak placement subsidized.

Separate campaigns for separate placement goals

Placement adjustments are set per campaign, not per keyword. If one keyword needs an aggressive top-of-search push and another does not, put them in different campaigns. This is one reason many advertisers isolate their best keywords into their own exact-match campaigns, as covered in Amazon PPC keyword isolation. It also gives you a clean placement report for each high-value term.

Mistakes to avoid

• Adding a big top-of-search adjustment on a keyword that does not convert. You will pay more to show a product that still does not sell.
• Stacking a large adjustment with up and down bidding on a new campaign.
• Reading the placement report over 7 days or less. Small samples swing wildly.
• Forgetting that adjustments affect every keyword and target in the campaign.

A simple placement review routine

Placement data changes as competitors adjust their own bids, as your reviews and price change, and as seasons shift. A light monthly routine keeps adjustments honest without constant tinkering.

1. Once a month, pull the placement report for your 10 to 20 highest-spend campaigns over the last 30 days, ending 3 days ago.
2. For each campaign, compare each placement's ACoS with your target. Flag any placement more than 25% above target that has 50 or more clicks.
3. If a flagged placement has an adjustment, cut the adjustment by about half. If it has no adjustment, lower the base bid 10 to 20% and raise the adjustment on the best placement to compensate.
4. If the top-of-search placement is well below target and impression share there is low, raise its adjustment by 10 to 25 points.
5. Write down every change with the date. Compare the next month's report against the notes before changing the same campaign again.

This routine assumes your bidding strategy stays the same during the test. If you change the strategy and the placement adjustments in the same week, you will not be able to tell which one moved the numbers.

Placement tuning works best alongside regular bid reviews. If you want a set of rules to run every week, see Amazon PPC bid optimization rules. And if your top-of-search spend is mostly on your own brand name, read defend your brand on Amazon ads before raising it further.
