Why Google Ads Belong in Your Amazon Advertising Stack
How to run Google Search and Shopping ads to Amazon listings, earn the Brand Referral Bonus, and use Amazon Attribution to measure what actually converts.
For most Amazon brands, the advertising conversation starts and ends inside Seller Central. Sponsored Products, Sponsored Brands, maybe DSP if the budget allows. Google is the other team’s game.
That framing made more sense when Amazon was actively buying Google Shopping traffic on its own. In July 2025, Amazon pulled its product listings from US Google Shopping entirely, stepping back from a channel where it had held roughly 60% of impression share. International markets saw a brief reactivation in August, but as of mid‑2026, Amazon has not meaningfully returned to U.S. Google Shopping auctions.
The implication for brands selling on Amazon is straightforward: that search-intent traffic still exists on Google, but Amazon is no longer competing for it on your behalf.
The brands that figure this out first have a window. And the financial math, once you account for Amazon’s Brand Referral Bonus and the ranking signal that qualified external traffic generates, makes the case more clearly than most sellers expect.
What Google Ads Can Actually Do for an Amazon Seller
Google Search and Google Shopping serve fundamentally different demand than Amazon’s internal ad formats.
When someone searches “best foam roller for back pain” on Google, they are in research mode. They have not opened Amazon yet. If your Sponsored Products campaign is where you capture that person, you are bidding against every other seller for a click that costs more every year. If you are running Google Search or Shopping ads, you can intercept that same intent before the Amazon auction starts.
Branded search defense is the other use case, and in some ways the more urgent one. If a competitor runs Google ads against your brand name, or if someone who already knows your product searches for it on Google and lands on a competitor, you have lost a conversion that had nothing to do with Amazon PPC advertising. A branded Google Search campaign costs very little when your Quality Score is high, and it closes a gap that most Amazon sellers leave open entirely.
Neither use case replaces your Sponsored Ads investment. They address demand that Sponsored Ads structurally cannot reach.
The Landing Page: Required for Shopping, Recommended for Search
The two main Google ad formats work differently when it comes to Amazon destinations, and the distinction matters.
Google Shopping campaigns require you to verify and claim the destination domain in Merchant Center. Because you do not own amazon.com, you cannot set an Amazon product detail page as the Shopping ad destination in your own Merchant Center account. A landing page on a domain you control is not optional for Shopping; it is the only compliant path.
Standard Google Search ads operate under different rules. Google does not prohibit Search ads from pointing directly to an Amazon product page. The destination needs to meet Google’s standard requirements for a working, policy-compliant page, and Amazon listings generally pass that bar. Direct-to-Amazon Search ads can be approved and can run.
The reason most practitioners recommend a landing page for Search anyway is not compliance. It’s performance and measurement. A shopper clicking a Search ad and landing cold on an Amazon listing gives you no tracking capability, no ability to add an Amazon Attribution tag at the click level, and no conversion leverage before they hit the marketplace.
A landing page between the ad and the listing lets you place the Attribution tag, carry social proof that pre-qualifies the shopper, and filter for purchase intent before they reach Amazon. Brands that treat the landing page as a pass-through tend to waste their Google spend. Brands that treat it as a selling step often see it improve their Amazon conversion rate because the shoppers who make it through are more qualified.
For both Shopping and Search, the flow that satisfies Google’s rules and Amazon’s external traffic programs while giving you the most measurement and conversion control is the same: Google ad to landing page you own to Amazon listing.
The Brand Referral Bonus Changes the Math
This is the piece most brands overlook when they calculate the cost of driving external traffic to Amazon.
Amazon’s Brand Referral Bonus pays enrolled sellers an average 10% bonus on the sales price of purchases that arrive through non-Amazon marketing efforts, tracked via Amazon Attribution tags. That bonus comes back as a credit against your referral fees. The rate varies by category, and the full rate table is available in Seller Central, but the average across categories is 10%.
In practice, this means that if you drive a $100 sale through a Google ad with an Amazon Attribution tag, Amazon credits approximately $10 back against your referral fees on that transaction. For a brand in a category with a standard 15% referral fee, the effective referral fee on that sale drops to around 5%. That margin difference funds a meaningful portion of your Google ad spend.
Two requirements apply. First, you need to be enrolled in Amazon Brand Registry, which requires an active or pending trademark. Second, every external link driving traffic to your Amazon listing must use an Amazon Attribution tag. If the tag is missing, the sale goes unattributed and the credit is not earned. Attribution tag generation is free and handled through the advertising console.
Amazon Attribution: The Measurement Layer
You cannot make good decisions about Google ad spend driving to Amazon without measurement, and Amazon Attribution is the tool that closes that loop.
Amazon Attribution is a free measurement solution available to Brand Registry sellers in the United States, Canada, United Kingdom, Germany, France, Italy, and Spain. It generates unique tracking tags you embed in your external ad URLs. When a shopper clicks your Google ad, lands on your listing, and converts within 14 days, that sale is attributed to that specific tag. You get full-funnel visibility: clicks, detail page views, add-to-carts, and purchases, all tied to the campaign that drove them.
The 14-day window uses a last-touch model. Whichever channel the shopper interacted with most recently before the purchase gets full credit. For Google Search and Shopping campaigns, which tend to capture intent close to purchase, this model works in your favor. Upper-funnel placements like YouTube or display ads will consistently appear to underperform in Attribution reporting because they rarely win last-touch credit. If you run both, measure them separately.
What Attribution enables beyond BRB eligibility is the ability to compare Google ad performance against the economics of your Sponsored Products campaigns on an apples-to-apples basis. TACoS across all external spend, not just Amazon’s internal ads, becomes a real number you can optimize against.
The Ranking Signal Most Sellers Do Not Account For
Brands that have run sustained external traffic campaigns to their Amazon listings consistently report an organic ranking benefit that compounds over time.
The mechanism is conversion quality, not traffic volume. A shopper who has already passed through your landing page and made a deliberate decision to buy before reaching Amazon converts at a higher rate than an average Sponsored Products click. Higher conversion rate on external traffic sends a positive signal to Amazon’s ranking algorithm, which weighs conversion performance as a core input. The organic visibility lift that follows is commonly called the ranking halo.
It is worth being precise about what this is and what it is not. Amazon has not officially documented “external traffic ranking benefit” as a stated algorithmic factor. What practitioners observe, consistently, is that listings receiving qualified external traffic tend to improve organic position over time at a rate that exceeds what internal campaign optimization alone produces. Whether that is an explicit weighting or an emergent effect of improved conversion metrics, the outcome is the same: the brands running external traffic tend to rank better.
That benefit does not show up in your ROAS calculation for the Google campaign. Which means brands that evaluate Google ads solely on direct return are undervaluing the investment.
Where This Fits in a Full-Channel Stack
Google is one channel in an external traffic strategy, not a standalone solution. The brands that extract the most value from it run Google in coordination with their Amazon Sponsored Ads, not instead of them.
The practical starting point for most scaling brands: a branded Google Search campaign to defend against competitor conquest, and a Google Shopping campaign targeting the highest-intent non-branded terms where your category has strong search volume. Set up Amazon Attribution before either campaign goes live. Apply for Brand Registry enrollment if you have not already.
The sophistication builds from there. Separate Attribution tags for each Google campaign let you measure which ad types and which audiences produce the highest-quality Amazon conversions. Over time, that data informs how you allocate budget across the whole stack, including how your Sponsored Ads investment interacts with what Google sends.
Managing Google, Amazon Sponsored Ads, and DSP as a coordinated strategy rather than three separate budgets is where the compounding happens. Canopy operates across all three because the brands we work with are past the point where any single channel is the growth lever.

For Google Shopping ads, no. Shopping campaigns require you to verify and claim the destination domain in Merchant Center, and since you do not own amazon.com, you cannot use an Amazon product page as the Shopping ad destination. A landing page on a domain you control is required.
For standard Google Search ads, the policy is different. Search ads can technically link directly to an Amazon product page as long as the destination meets Google’s standard requirements. Most practitioners still use a landing page in between because it enables Amazon Attribution tag placement, gives you conversion leverage before the shopper hits Amazon, and produces better-qualified traffic. The landing page is best practice for Search, not a policy requirement.
The Brand Referral Bonus is a program that pays enrolled sellers an average 10% bonus on sales generated through non-Amazon marketing, credited back against your referral fees. To qualify, you need Amazon Brand Registry enrollment (which requires an active or pending trademark) and Amazon Attribution tags on every external link. Sales that arrive without an Attribution tag are not credited. The exact bonus rate depends on your product category; the full rate table is in Seller Central.
Amazon Attribution is a free measurement solution that tracks how external traffic channels drive Amazon sales. It assigns credit using a 14-day last-touch model and gives you full-funnel data: clicks, product page views, add-to-carts, and purchases, all tied to the specific campaign that drove them. It is available to Brand Registry sellers in the US, Canada, UK, Germany, France, Italy, and Spain. Attribution tags are generated through the advertising console at no cost.
Practitioners consistently report an organic ranking benefit from qualified external traffic, typically attributed to the higher conversion rates that pre-qualified shoppers produce when they arrive at a listing. Amazon’s ranking algorithm weighs conversion performance heavily, so external traffic that converts well tends to improve organic position over time. Amazon has not formally documented this as a stated program mechanic, but the pattern appears across accounts running sustained external traffic campaigns. The benefit does not show up directly in Google campaign ROAS, which means evaluating Google spend on direct return alone tends to undervalue the full impact.
The core mechanics are the same: landing page, Amazon Attribution tag, Brand Referral Bonus eligibility. The difference is audience intent. Google Search and Shopping capture shoppers who are actively looking for a product or a brand. Meta and TikTok reach audiences who are not in search mode and require more creative work to generate purchase intent. Google tends to produce higher-conversion, lower-volume traffic. Meta and TikTok can produce higher volume at lower purchase intent. Both can earn the Brand Referral Bonus. Which channel to prioritize depends on your category, your creative capacity, and where your customers are in the purchase journey before they reach Amazon.
