Raise Amazon Bids for Black Friday With a Bid Ceiling

An uncapped 20% raise on a $2.30 bid lands at $2.76, and Amazon's dynamic bids can push the price paid higher still, in a week when clicks already cost more. Repeat that across 142 keywords and a Black Friday push turns into a margin leak.

Xnurta is an AI retail media platform for brands and agencies, and Xnurta MCP connects Claude, ChatGPT and other MCP clients to your Xnurta data. MCP (Model Context Protocol) is the open standard that lets an AI assistant connect to a tool like your ad platform. With it, one sentence raises what converts, caps every new bid and shows you every row before anything moves. If you've seen a bid tool run away with your budget, the ceiling is written into the sentence and every row waits for your yes.

What's the sentence that raises bids with a ceiling?

The prompt raises bids only where settled data earns it, on campaigns outside AI-managed groups, and caps each new bid before you see it.

On account [X], for campaigns outside AI-managed groups, raise bids by [20]% on Sponsored Products keywords and product targets with at least [20] clicks, [3] orders and ACOS at or below [25]% in the 30 days ending [14] days ago. Cap every new bid at $[2.50]. Leave brand terms and the [Clearance] campaigns unchanged. Show me old to new for every row before you change anything.

The ceiling is the highest bid you allow. A concrete rule: keep it well below break-even CPC, which is break-even ACOS times deal price times conversion rate. At an illustrative 30% break-even, a $75 deal price and a 14% conversion rate, that's $3.15. A $2.50 cap leaves about 26% headroom for dynamic bids and placement adjustments to lift the price paid before a click loses money. Set the 25% ACOS filter below each product's break-even ACOS at the deal price.

Why is each clause there?

Every clause stops one specific mistake, so the clause table doubles as the safety check.

What does the preview look like?

The raise comes back as a single table, and you approve it once. This is an illustrative account.

Read the capped rows before the rest, because they show where your ceiling is working. Then reply in plain English: “Apply all except rows 2 and 142,” or “Cap everything in [Kitchen] at $2.20 and show me again.” Nothing changes until you say yes. Then each change is sent to Amazon, read back and logged under the teammate who approved it. That's 142 bid edits approved in one reply. Write access is turned on per account by your CSM. Run the raise once, on Thanksgiving afternoon, then leave bids alone on Friday and watch budget pace.

How do you raise grouped campaigns?

For campaigns in AI-managed groups, raise the group's limits and let Xnurta's AI do the keyword work. A group's campaigns share one target ACOS, budget and bid range, and Xnurta's AI sets their bids between your conversations, within that range. A hand raise on those keywords would simply be adjusted again.

For my [Kitchen] and [Gifts] AI-managed groups, draft a Black Friday schedule for [Nov 26 to Nov 30]: raise the bid range maximum by [20]% and set target ACOS to break-even at deal price from these margins [paste]. Show me the list. Don't apply yet.

Group changes apply as soon as you approve them, without a preview card, which is why the prompt asks for the list. After the last window, the group returns to its standing settings.

How do you push top of search without raising every bid?

Change the top-of-search placement adjustment on campaigns outside groups, rather than every bid.

For campaigns outside AI-managed groups with ACOS at or below [25]% in the 30 days ending [14] days ago, raise the top-of-search placement adjustment by [15] points. Show each campaign's current adjustment and bidding strategy, old to new, before applying.

Ask for the bidding strategy on purpose. Your ceiling caps the bid, not the price paid: Amazon's dynamic bids (up and down) can raise a bid for top of search, and placement adjustments multiply on top. Stack one lever at a time and check placement results before adding the next.

How do you undo the raise after the event?

The undo is one prompt, because the bids from before the raise can be read back from the operation log.

From the operation log, list the bids from before the raise I approved on [Thursday, Nov 26] in account [X]. For keywords that did not convert at or below [25]% ACOS during the event, on provisional data through [Dec 1], set the bid back to its old value. Keep the rest, and flag them for a re-check on settled data around [Dec 14]. Show me old to new before applying.

That is a new bid edit with its own preview, and a change that was wrong outright can also be rolled back from the operation log. The Promo Adjustment Reset Skill takes bids, budgets and group settings changed for the promo back toward where they were. If you'd rather ease down, stage your own previewed edits over five days instead of snapping back in one step. Pause, never archive, because archived items can't be recovered.
