Your Sponsored Products Ads Are Now Running Inside Creator Reviews And Nobody Asked You First

The controls you actually have

At the campaign level, under the settings for ads served off Amazon, you get two options:

• Increase reach — the default. Allows off-Amazon delivery, creator inventory included.
• Limit off-Amazon spend — restricts offsite delivery. Amazon notes this may reduce impressions.

Both are adjustable mid-flight, and both are editable in bulk via the off-Amazon ad serving bulksheet column. If you’re touching more than a handful of campaigns, use the bulksheet — the same approach we walk through in auditing your account with bulk files.

Beyond that: you can exclude specific creators, maintain deny list preferences for sites and apps, and Amazon automatically reviews and blocks unsafe third-party properties. EU advertisers also get a pricing transparency report under the Digital Markets Act, which discloses something worth knowing — third-party publishers may receive additional funds from Amazon beyond the auction clearing price.

One thing to be clear-eyed about: there is no documented account-wide off switch. “Limit off-Amazon spend” is a restriction, not a kill switch, and it’s applied campaign by campaign. Anyone telling you to “just turn it off” hasn’t read the documentation.

Your audit this week

Most guidance published before August 10 told you to pull a baseline first. That ship has sailed — you’re ten days in. Here’s the version that works from where you actually are.

1. Get the closest thing to a baseline you can still get. Pull the Sponsored Products Placement Report for August 1–9 and again for August 10–20. That’s your before and after. It’s not a clean experiment — mid-August seasonality is in there too — but the delta on off-Amazon impressions, clicks, and spend is real and it’s the only baseline still available to you. Do this before the window gets any wider.

2. Quantify it before you react. Find off-Amazon rows in the Placement Report (or pull Placement Classification via the Ads API). If creator inventory is 2% of your spend, calm down and monitor. If it’s 15%, keep reading. Don’t restructure anything on the strength of a vibe.

3. Check your most heavily modified campaigns. Any campaign leaning hard on Top of Search or Product Pages multipliers is now behaving differently than designed, per the section above. These are your highest-risk campaigns, not your highest-spend ones.

4. Set the control by campaign job, not across the board. More on this below.

5. Freeze aggressive negative keyword harvesting. Until you can separate real search terms from inferred ones.

6. Don’t restructure before Q4. If this analysis makes you want to rebuild your account architecture, write the plan down and execute it in January. Ripping up campaign structure in September, weeks out from Q4, trades a known problem for an unknown one at the worst possible time.

Which campaigns should limit off-Amazon spend?

Set this per campaign job. A blanket policy is the wrong answer in both directions.

Lean toward limiting:

• Branded defense. Someone searching your brand on Amazon has intent you already own. Paying to reach a reader who wasn’t looking for you is a different purchase, and you probably didn’t budget for it inside a defensive campaign.
• Tightly capped campaigns where on-Amazon impression share is the whole point.
• Exact-match harvest campaigns built on proven converting terms. The precision you built is exactly what inferred keywords erode.

Lean toward allowing:

• Discovery and top-of-funnel campaigns. Creator content is genuinely upper-funnel inventory. If that’s the job, this is on-brief.
• New product launches that need reach and don’t have search volume yet.
• Broad-match research campaigns where you’re paying for information as much as conversions.

Then judge it on data. Give it a few weeks with clean reporting and evaluate the placement on its own numbers rather than on how you feel about being auto-enrolled.

What we still don’t know

Being honest about the gaps, because a few of these matter:

• Amazon’s documentation says “certain campaign controls are unavailable for offsite placements” without specifying which ones. That’s an unhelpfully large blank.
• It’s unclear whether individual creator accounts are addressable through deny lists, or only through the separate creator-exclusion mechanism.
• The setting labels vary across sources — some report “Increase reach” and “Limit off-Amazon spend,” others “Maximize reach” and “Minimize spend.” Check what your own console actually says rather than trusting any blog post, including this one.
• There’s no published data yet on how creator-placement conversion rates compare to on-Amazon placements. Anyone quoting you a number this week is guessing.

The bottom line

The mechanic worth internalizing isn’t creator content specifically. It’s that Amazon shipped a new inventory type into live campaigns on six days’ notice, on by default, with placement modifiers inert and reporting that mixes synthetic keywords into a report you use to make targeting decisions.

Amazon pulled $19.8 billion in advertising revenue in Q2 2026, up 26% year over year. Sponsored Products is the engine of that number. Expect more inventory expansion, and expect it to arrive the same way — enrolled by default, announced in a support-article revision.

The defensible response isn’t outrage, it’s instrumentation. Know what percentage of your spend sits on inventory you didn’t choose. Check it monthly. That’s a habit worth more than any single setting.

Pull the Placement Report. Compare August 1–9 to August 10–20. Then decide.
