Amazon Algorithm Changes: Adapt Fast | Marknology

When Amazon changes the algorithm, the best response is understanding what actually changed, not panicking and making random adjustments to your listings. Amazon updates its search and ranking algorithm constantly, and most of the time, the changes reward the same things: relevant products, strong conversion rates, and great customer experience. At Marknology, Andrew Morgans and our Kansas City team have navigated every major algorithm shift since 2014, and the brands that succeed are the ones that focus on fundamentals instead of chasing shortcuts.

On the Startup Hustle podcast, Andrew explains it this way: "Amazon does not change the algorithm to hurt you. They change it to help customers find better products faster. If you are selling a great product with a great listing, algorithm changes work in your favor."

How Does the Amazon Search Algorithm Work?

Amazon's search algorithm (often called A9 or A10) has one goal: match shoppers with products they are most likely to buy. The algorithm considers:

• Relevance: How well your listing matches the search query (title, bullets, backend keywords)
• Performance: Your sales velocity, conversion rate, and click-through rate
• Customer satisfaction: Reviews, return rates, and seller metrics
• Availability: In-stock inventory, fulfillment method, and delivery speed
• Pricing: Competitive pricing relative to similar products
• External traffic: Sales driven from outside Amazon (Google, social media, email)

The algorithm weighs these factors differently depending on the search query. High-purchase-intent searches (like "buy wireless earbuds") weight conversion rate heavily. Informational searches weight relevance more. Learn more in our optimize your Amazon listings.

Amazon is not Google. On Amazon, the algorithm cares about one thing more than anything else: are people buying this product when they find it? Conversion is king.-- Andrew Morgans

What Actually Changed in the Latest Update?

Amazon does not announce algorithm changes the way Google does. But based on pattern analysis across hundreds of brands, here are the trends we have observed:

• External traffic matters more: Products that receive traffic from Google, social media, and email marketing are ranking higher than before
• Brand signals are stronger: Branded search volume and repeat purchases carry more weight
• Review quality over quantity: Detailed reviews with photos and video seem to carry more weight than sheer review count
• Content depth rewards: Listings with A+ Content, video, and complete Brand Stores rank more consistently
• Advertising attribution: The relationship between ad spend and organic rank has shifted. Ads still help, but organic factors are weighted more heavily than before.
• Delivery speed: Products with faster delivery (especially same-day and next-day) are getting ranking preference

These trends reinforce what Marknology has always believed: build a real brand, create great content, and deliver an excellent customer experience. The algorithm rewards what customers want.

What Are the Most Important Amazon Ranking Factors?

In order of importance based on our experience managing 250+ brands at Marknology:

• Sales velocity: The number of units you sell per day is still the strongest ranking signal
• Conversion rate: Higher conversion rate means Amazon shows your product to more people
• Keyword relevance: Your listing must contain the keywords shoppers are searching for
• Reviews: Both quantity and quality. A 4.5 star rating with 200 reviews outranks a 4.0 with 2,000 in many cases.
• Click-through rate: Your main image and price determine whether people click from search results
• Inventory availability: Going out of stock tanks your ranking and it takes weeks to recover
• Fulfillment method: FBA and Seller Fulfilled Prime products rank higher than standard FBM
• Price competitiveness: Not always cheapest, but reasonably priced for the category

If you are strong in all of these areas, algorithm changes will not hurt you. They will hurt your competitors who were relying on tricks.

How Do I Know If an Algorithm Change Affected Me?

Here are the symptoms of an algorithm shift versus other common problems:

Signs of an Algorithm Change

• Multiple products across your catalog lost ranking simultaneously
• Competitors who previously ranked below you are now above you
• Your impressions changed but your listing content has not
• Industry forums and groups are reporting similar patterns

Signs It Is NOT an Algorithm Change

• Only one product is affected (more likely a listing issue or competitor action)
• Your sessions dropped but organic rank stayed the same (could be seasonal)
• Your conversion rate dropped (listing or pricing problem, not algorithm)
• Your ads stopped performing (advertising issue, not organic algorithm)

Use keyword ranking tools to track your positions over time. If you see a sudden shift across many keywords simultaneously, that is likely an algorithm update. If it is isolated to one product or a few keywords, look for product-specific causes first. Explore our Amazon search optimization services for expert support.

How Do I Adapt to Amazon Algorithm Changes?

When you confirm an algorithm change affected your rankings, here is the adaptation playbook:

Immediate Actions (Days 1 to 7)

• Document what changed: which keywords, which products, how much
• Check your listing for any compliance issues that might have been newly flagged
• Increase PPC spend on affected keywords to maintain visibility while you adapt
• Review competitor listings that gained rank to identify what they are doing differently

Short-Term Adjustments (Weeks 1 to 4)

• Refresh your listing content: update images, rewrite bullets, add video if you have not
• Optimize backend keywords to ensure full indexing
• Increase external traffic through social media, email, and influencer campaigns
• Ramp up your review generation strategy through Vine and follow-up messaging

Long-Term Strategy

• Build brand searches through off-Amazon marketing
• Develop a content flywheel: regular A+ Content updates, video, and Brand Store refreshes
• Partner with an agency like Marknology that monitors algorithm changes in real time and adapts proactively

The worst thing you can do is nothing. The second worst thing is panic-changing everything at once. Be strategic, test changes one at a time, and track the results. Learn more in our Amazon advertising hub.

How Do I Future-Proof My Amazon Rankings?

Every algorithm change Amazon has made in the last decade has moved in the same direction: rewarding brands that provide the best customer experience. Here is how to build rankings that are resilient to any future changes:

• Invest in content: Professional images, video, A+ Content, and a complete Brand Store. This never goes out of style.
• Build external traffic: Do not rely 100% on Amazon's organic search. Drive traffic from Google, social, and email.
• Earn authentic reviews: Great products, great packaging, and great customer service lead to great reviews naturally
• Diversify keywords: Do not rely on 3 keywords. Rank for 50+ relevant search terms.
• Maintain brand health: Keep your account metrics strong. Low return rates, fast shipping, responsive customer service.
• Stay informed: Follow industry experts, listen to podcasts like Startup Hustle, and work with an agency that stays current

At Marknology, algorithm adaptability is built into our ongoing strategy for every brand. We do not wait for changes to happen. We build listings and brands that thrive regardless of what Amazon does next. See our client portfolio for proof.

Frequently Asked Questions

How often does Amazon change its search algorithm?

Amazon makes small adjustments to its search algorithm continuously, similar to how Google updates daily. Major algorithmic shifts that noticeably change rankings happen a few times per year. Amazon does not announce these changes publicly, so sellers need to monitor their rankings and stay connected to the Amazon seller community. Marknology tracks these changes across 250+ brands.

What is the difference between Amazon A9 and A10 algorithm?

A9 was Amazon's original search algorithm. A10 is the commonly used name for the updated version that places more emphasis on external traffic, organic sales, and brand signals. Amazon has never officially used the term 'A10,' but the seller community uses it to describe the shift in ranking factors observed over the past few years.

Can I game the Amazon algorithm?

Short-term manipulation tactics (fake reviews, search-find-buy schemes, keyword stuffing) may work temporarily but always result in penalties when caught. Amazon actively detects and punishes these tactics. The only sustainable strategy is building a genuinely great product with optimized content and authentic customer engagement.

Why did my Amazon ranking drop for no reason?

There is always a reason, but it is not always obvious. Common causes include algorithm updates, a competitor increasing ad spend, seasonal shifts, a minor listing change you did not notice, or an indexing issue. Andrew Morgans and the Marknology team diagnose ranking drops by checking all possible causes systematically.

Does advertising help Amazon organic rankings?

Yes. Paid sales contribute to your overall sales velocity, which is a key ranking factor. However, the relationship is indirect. Amazon does not directly boost organic rank because you spend on ads, but the increased sales from ads improve your performance metrics which in turn improve organic rank.

How important are external traffic sources for Amazon rankings?

Increasingly important. Amazon's algorithm now gives significant weight to traffic and sales originating from outside Amazon (Google, social media, email, influencers). This is because external traffic proves genuine demand and brand awareness. Brands that only rely on Amazon's internal traffic are at a disadvantage.
