Amazon Advertising on Google

Executive summary

Amazon generated $68.6 billion in advertising revenue in 2025, pushing internal CPCs to record highs and forcing smart brands to acquire traffic externally.
In mid-2025, Amazon abruptly paused its own Google Ads spending in the US, leaving a massive visibility gap for sellers who relied on subsidized search traffic.
Driving Google Ads traffic to your Amazon listings using Amazon Attribution qualifies you for the Brand Referral Bonus, yielding an average 10% rebate on your referral fees.
External traffic is no longer optional. Top-performing brands now see up to 41% of their total sales driven by off-platform search channels, drastically boosting organic rank.

Picture the scene. It’s the middle of Q3 2025, and your Amazon sales suddenly flatline. You scramble. You check your Sponsored Products campaigns, audit your inventory levels, and refresh your Buy Box win rate. Everything looks perfectly normal. What you don’t realize is that Amazon just quietly stopped bidding on your brand terms on Google.

Overnight, that steady stream of off-platform shoppers vanished. Your competitors, who were running their own external Google Ads campaigns, scooped them up without breaking a sweat. This is the harsh reality of relying entirely on Amazon’s internal ecosystem. You do not own the traffic. When they turn off the tap, your revenue dries up.

The $68.6 Billion Elephant in the Room

Start with the cold, hard data. Amazon’s internal advertising machine is an absolute beast. By 2025, it generated a staggering $68.6 billion in ad revenue, cementing its place as the third-largest advertising platform globally behind Google and Meta. That massive revenue number sounds great for their shareholders, but it comes directly out of your shrinking profit margins.

Internal CPCs are crowded, pricey, and brutally competitive. In highly saturated niches, generic non-branded terms often demand clicks well above $2.00. Here is where the vast majority of sellers fail. They keep pouring budget into the exact same saturated internal campaigns, fighting bloody bidding wars for a fraction of top-of-search placement.

Smart operators look elsewhere. By targeting high-intent Google queries—like “best organic coffee on Amazon Prime”—you bypass the internal bloodbath entirely. Google Ads often deliver the exact same buyers but at a 15-30% cheaper CPC. If you want to understand how this external traffic fits into a broader, holistic internal strategy, our comprehensive guide on How Does Amazon Advertising Work? A Strategic Guide breaks down the fundamental mechanics you need to master first.

Google Ads vs Amazon Internal PPC

Let’s compare apples to apples. Buying traffic on Google to send to your Amazon storefront isn’t just an exercise in diversification. It is a calculated play for algorithmic dominance.

Amazon’s search algorithm intensely rewards external traffic. When a user searches on Google, clicks your ad, lands on your product detail page, and makes a purchase, it sends a massive brand authority signal to Amazon. This external validation boosts your organic rank significantly faster than a purely internal PPC sale. Want to dominate non-branded terms? You need that external juice. That is a core concept we teach when Mastering Generic Keywords on Amazon for Higher Sales.

Metric / Feature	Google Ads to Amazon	Amazon Internal PPC
Cost Per Click (CPC)	Often 15-30% lower for high-intent niches	Increasingly high ($0.97 - $2.00+ avg)
Algorithm Impact	High. External traffic heavily boosts organic rank	Moderate. Expected baseline behavior
Financial Incentives	Average 10% Brand Referral Bonus rebate	None. You pay full price for clicks and referrals
Cannibalization Risk	Low. Captures off-platform shoppers	High. You often pay for buyers who would have bought organically

What changed in 2025-2026: The Great Pullback

What shocks me is how few sellers noticed the seismic shift that happened last year. The playbook you used in 2023 is officially dead.

July 2025: Amazon’s Sudden Google Exit

In a matter of 48 hours in July 2025, Amazon dramatically pulled back its Google Ads spending in the US market. They dropped from an estimated 50-60% impression share to nearly zero across countless branded and non-branded queries. Brands panicked. They realized they had been free-riding on Amazon’s ad budget for years. When Amazon stopped bidding on “Buy —> —> —> —> —> —> —> —> —>”, direct-to-consumer competitors swooped in and stole those top spots. The lesson is brutal but clear. If you do not control your visibility on Google, you do not own your brand.

The Golden Era of Amazon Attribution

To soften the blow and incentivize sellers to buy their own external ads, Amazon doubled down on its Attribution tool. It generates unique tracking tags you append to your Google Ads URLs. When a shopper clicks that Google ad and buys on Amazon within 14 days, Amazon records it. No more guessing. You know exactly which Google keyword drove that $50 sale, allowing you to scale budgets with precision.

The 10% Brand Referral Bonus

Here is the real kicker. If you are Brand Registered, Amazon literally pays you to bring outside traffic. The Brand Referral Bonus (BRB) credits you an average of 10% of the sale price against your referral fees. Think about the math. If you spend $10 on Google Ads to generate a $100 sale, Amazon gives you a $10 referral fee credit. Your external traffic just became entirely free, subsidizing your acquisition costs in a way internal PPC never could.

Epinium data

We’ve tracked over $40M in ad spend and found that brands running parallel Google Search campaigns to Amazon listings observe a 22% lower blended Customer Acquisition Cost (CAC) compared to those relying exclusively on Sponsored Products.

The Contrarian Truth About Organic Ranking

Let me dismantle a toxic myth right now.

“I already rank #1 organically on Amazon for my keyword. I shouldn’t waste money bidding on it via Google.”

Wrong. Completely backward. If you don’t bid on your own brand terms on Google, a competitor will. They will route that traffic to their Amazon listing or their DTC site, and you lose the sale. More importantly, Amazon’s AI-driven search algorithms, like Rufus, crave external signals. They do not just look at internal conversion rates anymore. They look at your overall brand footprint across the web.

Traffic flowing in from Google signals high brand authority. This builds an algorithmic moat around your top organic positions. You are not just buying a sale; you are buying algorithmic insurance. You can dive deeper into this specific ranking dynamic in our breakdown: Amazon Advertising Explained: Strategy for Sellers.

Frequently Asked Questions

Does Google Ads traffic convert well on Amazon?

Yes, but it depends heavily on user intent. Shoppers searching for “buy —> —> —> —> —> —> —> —> —> on Amazon” have extremely high intent and convert at rates similar to internal Sponsored Products. Broad top-of-funnel queries will have lower conversion rates, which is why strict keyword match types are essential.

How do I track Google Ads sales on Amazon?

You must use Amazon Attribution. It allows you to generate specific tracking URLs for your Google Ads campaigns. When a user clicks the ad and buys within 14 days, the sale populates in your Amazon Advertising console, showing you exact revenue tied to your external spend.

Do I need Amazon Brand Registry for the referral bonus?

Absolutely. The Brand Referral Bonus is strictly gated behind Brand Registry. If you are a reseller or haven’t registered your trademark with Amazon, you can still use Attribution for tracking, but you will not receive the 10% fee rebate.

What happens if a customer clicks my Google Ad but buys a competitor’s product on Amazon?

This is the hidden risk of external traffic. If you send a shopper to a standard product detail page, they will see your competitors’ Sponsored Display and Sponsored Products ads. If they click away and buy a competitor’s item, you paid for the click, but your competitor got the sale. This is why many brands choose to send Google traffic to their custom Amazon Storefront instead.

Should I send Google traffic to a product detail page or my Storefront?

Send highly specific, single-product searches straight to the product detail page to minimize friction. Send broader brand searches to your Storefront. Your Storefront has zero competitor ads on it, creating a closed ecosystem where the shopper is forced to choose between your products, not your competitors’.

How does the 14-day attribution window work?

Amazon Attribution uses a 14-day last-touch model. If a shopper clicks your Google Ad on Monday, doesn’t buy immediately, but returns to Amazon organically the following Thursday to purchase the item, that sale is credited to your Google Ad campaign.

No, the Brand Referral Bonus is currently only applied to the initial purchase. Subsequent recurring orders triggered by Subscribe & Save do not generate ongoing referral fee credits, though the lifetime value of that acquired customer remains highly profitable.

Can I use Google Shopping Ads for Amazon listings?

Historically, this was complex because Amazon dominated the Shopping carousel. However, following Amazon’s pullback, brands can now run their own Google Shopping (Performance Max) campaigns pointing to Amazon listings. Just ensure your product feed is meticulously managed and Attribution tags are properly appended to the destination URLs.

The Future of Search and Marketplaces

As we move deeper into 2026, the walls between search engines and retail marketplaces are completely crumbling. You can no longer treat Google and Amazon as isolated silos. They are two halves of the exact same purchasing journey.

The brands that dominate tomorrow will not just be the ones who are best at optimizing an auto-campaign in Seller Central. They will be the ones who master external acquisition, exploit the referral bonuses, and feed the Amazon algorithm exactly the off-platform signals it craves. Don’t let your competitors buy your customers on Google while you fight over scraps on Amazon.
