If you’re running Amazon PPC campaigns as a seller, you know how unpredictable algorithm updates can be. One day, your campaigns are hitting targets, and after a major update (like A10), clicks, conversions, and sales can suddenly drop.
That’s because Amazon now evaluates not just your bids, but listing relevance, conversion rates, customer engagement, and external traffic when deciding ad visibility.
Understanding these shifts and responding strategically is crucial. This blog will break down what changes during an update, how those changes impact PPC performance, and actionable steps to recover and stabilize campaigns quickly.
TL;DR – How Can I Recover Performance After a Major Algorithm Update on Amazon?
Algorithm updates can shake up PPC campaigns, but the good news is that recovery is doable with the right approach. Here’s a quick snapshot of the key steps:
- Boost bids and budgets on high-intent campaigns to help Amazon reassess your relevance.
- Focus spending on top-of-search and high-performing placements to get faster results.
- Run automatic and manual campaigns to uncover any missing keywords.
- Slowly trim bids and remove non-converting terms to keep ad spend efficient.
- Watch CTR, conversions, and sessions to see how your campaigns are bouncing back.
Keep reading to get a detailed view of these steps and how to restore stable, profitable PPC performance.
What Typically Changes During a Major Amazon Algorithm Update
When Amazon pushes a major algorithm update, it’s usually not a single change. It’s a rebalancing of how relevance, performance, and customer experience are evaluated across the platform. Those shifts ripple straight into PPC.
Here are the core areas that tend to change:
Pricing Becomes Key Visibility Factor
Price has always mattered, but after algorithm updates, Amazon is less forgiving of products that are priced above their similar alternatives, reducing ad visibility before shoppers even encounter the listing.
PPC can’t fix pricing that doesn’t convert. Even if you win the auction, Amazon will pull back ad exposure when shoppers don’t buy.
Listing Relevance is Re-Scored
With new updates, Amazon will re-evaluate your listing quality. If you have clear titles, readable bullets, and accurate keyword alignment, your products will outperform any keyword-heavy copy.
One Reddit user, Boots_RR, mentions:
“So, for one, keyword stuffing isn’t really a thing you want to be doing anymore, according to all the advice I’ve been given. Keywords in title, then well-targeted keywords in your fields with a couple of longer tail ones have worked well enough for me.”
Amazon also has a tracker on how shoppers are interacting with your listing. If they click, scroll, and buy, your relevance improves, and vice versa. The relevance score you gain directly influences how your ads get placed and CPCs.
Seller-Level Performance Signals Gain Importance
Amazon doesn’t just rank products. It evaluates sellers. Metrics like order defect rate, late shipment rate, cancellation rate, returns, and Voice of the Customer scores all feed into seller authority.
When these updates roll out, Amazon tends to give them more focus. If seller authority slips, PPC performance often follows, even without changes to campaigns.
CTR and Conversion Rate Are Prioritized
With updates, the click-through rate and conversion rate have become critical indicators. A high CTR indicates that your Amazon ad is relevant. A high conversion rate tells you that Amazon shoppers trust your product.
When either of them drops, Amazon limits your exposure. That is why your performance often falls even when bids and budgets stay the same.
Sellers have noticed this shift firsthand. One Reddit user, wintoo_, shared how small listing changes had a direct impact on ad performance:
“It took me a while until I realized my competitors weren’t beating me because their products were better; they were beating me because they understood what customers thought was better.
People pointed out small visual cues that made my competitors look “more premium,” even though they weren’t.
Once I fixed those cues, my CTR actually climbed.”
Reviews and Post-Purchase Experience Matter More
When your product has good reviews and a low return rate, people will automatically place more trust in it.
This means you need to address your negative reviews, or your returns will rise, and Amazon can reduce your listing’s exposure. Algorithm updates usually make that drop more obvious.
Brand Strength and External Traffic Signals Gain Importance
Newer updates place more weight on brands that drive high-quality traffic and generate repeat engagement, not just one-time visits. External traffic, repeat buyers, and strong brand engagement all help improve visibility.
Because of that, PPC works best as part of a broader growth strategy rather than as a standalone lever.
How Amazon Algorithm Changes Affect PPC Performance
Amazon algorithm updates don’t just tweak rankings. They change how PPC works at a structural level. The biggest shift is that Amazon now prioritizes what happens after the click just as much as the bid itself.
Here’s how those changes affect PPC performance in practice:
Bids Matter Less without Strong Listing Performance
In some newer versions of the A10 algorithm, high bids alone won’t guarantee visibility. Amazon will evaluate whether those ads are leading to clicks and conversions, then adjust the delivery accordingly.
Two advertisers can bid the same amount, but the one with stronger engagement and conversion rates will receive more impressions at a lower effective cost.
Performance Volatility Increases After Updates
Algorithm updates often introduce certain short-term instability in PPC performance. Even those well-optimized campaigns that worked can see sudden changes in impressions, CPCs, and conversions as Amazon recalibrates relevance and delivery.
During this period, your day-to-day performance may fluctuate without making any campaign changes. This is typically part of normal system rebalancing, not a sign that campaigns are broken.
CPCs Increase when Relevance Declines
In many competitive categories, CPCs have been climbing by roughly 10–15% year-over-year. But this isn’t just about more sellers bidding on the same keywords.
When the relevance slips, Amazon simply makes you pay more. Ads that bring in the right shoppers and convert consistently get rewarded with cheaper clicks, while weaker traffic gets priced higher.
Organic Performance and PPC Are More Closely Linked
Amazon no longer treats PPC as a standalone channel. If your ads drive real sales and engagement, those signals can actually help your organic rankings.
But when ads drive clicks without conversions, Amazon sees that as a relevance issue and pulls back visibility for both paid and organic placements. That’s why PPC and organic rankings often move together after an update.
External Traffic Influences PPC Efficiency
Amazon is paying more attention to the data related to where your traffic comes from. When shoppers arrive from social, email, or search, it indicates real demand and brand strength.
If that traffic converts, it strengthens engagement and helps stabilize PPC performance over time.
Automation Now Shapes Bid Behavior
Automation amplifies what’s working and quickly penalizes what isn’t. Amazon’s machine learning adjusts bids and delivery in real-time based on shopper behavior.
However, manual bidding still matters, especially for smart, hands-on adjustments on well-structured campaigns, which can steer performance more effectively.
Ad Formats Play a Bigger Role in Performance
Sponsored Brands, Sponsored Display, and video ads are now essential parts of a balanced PPC strategy.
These formats typically drive higher engagement than Sponsored Products alone, providing stronger relevance signals to the algorithm and improving overall account performance.
How to Recover Amazon PPC Performance After an Algorithm Update
After an algorithm update, PPC performance usually dips before it stabilizes.
At this point, your goal shouldn’t be to pause all your campaigns, but rather to help Amazon quickly re-evaluate your relevance under its updated system.
These steps focus on restoring visibility first, then efficiency:
Rebuild Visibility with Strategic Bid and Budget Adjustments
Algorithm updates often come with a reset of how Amazon distributes impressions. Increasing the bids and budgets on high-intent campaigns will give the system enough data to reassess your performance.
You need to monitor those sessions closely. If spend and sessions are rising together, then targeting is aligned. If spend increases without traffic growth, relevance, or keyword selection, it likely needs correction.
Prioritize campaigns that are already near your target ACoS or that show consistent conversion signals.
Optimize Bids by Placement
After an update, you might notice that placement performance is more clearly separated. The top-of-search placements are the ones that usually generate better CTR and conversion rates, and those signals matter more than ever.
Instead of spreading the budget evenly, strategically adjust your bids for placements that are proving their value. Increasing spend behind high-engagement positions will send stronger signals to the algorithm, helping accelerate recovery.
Expand Keyword Coverage to Restore Relevance
Algorithm updates often reveal gaps in your keyword coverage. Launching a new automatic and manual campaign will give Amazon fresh signals and help you relearn where your product fits.
Amazon PPC automatic campaigns are best for discovery, while manual campaigns give you control. Separating match types keeps signals clean and makes optimization easier.
At this stage, the goal is data collection, not immediate efficiency.
Transition from Performance Recovery to Profitability
Once the traffic and conversions start to stabilize, shift your focus towards efficiency. Gradually reduce bids on those non-converting keywords or ASINs if you want to minimize wasted spend without disrupting the momentum you’ve gained.
Those PPC search term reports are very critical after the update. Removing any irrelevant or high-spend, no-sale terms will be a great move if you want to protect your CTR and strengthen relevance.
Track Leading Performance Indicators
During recovery, don’t just watch ACoS. Keep an eye on CTR, conversions, and session growth; these show if the algorithm is moving in your favor.
As spending is optimized, total sales should remain stable. When that happens, your campaigns are stable, and you can confidently optimize for growth.
Common Mistakes to Avoid
Recovering from an algorithm update isn’t just about raising bids or launching new campaigns.
Even small missteps, like the ones mentioned below, can slow things down:
- Neglecting Data Monitoring: ACoS alone won’t tell you the whole story. You need to keep an eye on session growth, CTR, and conversion rates; these show whether the algorithm is responding. Ignoring them can make problems sneak up on you.
- Skipping Post-Update Testing: The algorithm shifts how traffic flows. Don’t stick to your old campaigns or keywords; you’ll miss opportunities. Instead, you can run small tests with new keywords, placements, or ad formats to help Amazon view your relevance faster.
- Overreacting to Short-Term Fluctuations: It’s normal to see swings in PPC performance after an update. Pausing campaigns or slashing budgets too quickly often backfires. A measured, patient approach usually yields faster results.
- Overlooking Customer Experience Signals: High returns, negative feedback, or poor post-purchase engagement now have a bigger impact on visibility. Ignoring these signals can suppress both paid and organic performance even if campaigns are running.
- Ignoring Search Term Cleanup: Irrelevant or non-converting search terms waste the money you spend on ads and hurt CTR and relevance. Better to review search term reports very regularly and add all the low-performing terms as negatives, keeping campaigns efficient and protecting long-term ranking.
