Sellers who come to Amazon from Google Ads expect a familiar system. Keywords, match types, bids, an auction. It is familiar for about a week. Then the differences start costing money: a keyword list full of research terms that never convert, an attribution window that makes yesterday's numbers wrong, a bid strategy that worked on Google and burns budget here.

This comparison is for advertisers moving in either direction. It covers the differences that matter, in the order they usually surprise people.

Where the click lands

Google sends the shopper to your website. You built the page, you control it, and the conversion depends on it. Amazon sends the shopper to a product detail page on Amazon, built from your listing but owned by Amazon, with competitors' sponsored products on it and, for shared listings, other sellers' offers.

This changes what you optimize. On Google, landing page work is half the job. On Amazon, the listing is the landing page, the ad, and the product in one, and the levers are the main image, title, bullets, price, and reviews. There is no separate creative for Sponsored Products; the listing is the creative. The sponsored ad types overview covers what each format does and does not let you control.

What the shopper wants

Google searches span the whole funnel: questions, research, comparisons, and purchases. Amazon searches are overwhelmingly purchase-intent. Nobody searches Amazon to learn how something works; they search to buy one.

A keyword list built for Google is full of terms that make sense on Google and do not convert on Amazon. "Best" and "vs" and "how to" terms, informational phrasings, brand-plus-review queries. Start the Amazon list from the commercial subset, and replace it with Amazon's own search term data as soon as it exists. Match types are named the same on both platforms and behave slightly differently, which is its own trap.

What the auction rewards

Both auctions weigh bid against relevance. Google's quality score is partly documented and heavily influenced by landing page experience and ad copy. Amazon's relevance signal is undocumented and heavily influenced by conversion history: an ad that has produced sales on a keyword wins that keyword more cheaply over time.

This means Amazon rewards consistency more than Google does. A campaign that is paused and restarted loses history. A keyword moved between campaigns starts over. The habit of constant restructuring that some Google advertisers bring with them is expensive on Amazon.

Attribution

Google attribution is configurable and, with analytics connected, fairly transparent. Amazon attributes a sale to an ad click within a fixed lookback window (commonly 7 days for Sponsored Products, longer for some formats), reports only ad-attributed sales, and keeps counting for days after the click.

Two consequences. Yesterday's ACoS is always higher than it will be once late orders settle; compare only settled periods. And the console shows only ad-attributed sales, so the organic lift that ads produce (the ranking improvement from sales velocity) is invisible in ad reporting. TACoS, which divides ad spend by total sales, is how sellers see it, and it has no direct Google equivalent.

Campaign types

Google: Search, Shopping, Display, Video, Performance Max, Demand Gen, and more, each with its own setup and bidding. Amazon: Sponsored Products, Sponsored Brands, Sponsored Display, and DSP for larger advertisers. Fewer types, and most sellers run one or two.

The simplicity is real and it is also why Amazon advertisers underinvest in structure. With one campaign type doing most of the work, the structure within it (one product per campaign, exact match separated from discovery, negatives maintained) matters more than it does on Google, where the campaign type itself does some of the separation. The structure guide covers the Amazon version.

Bidding

Google offers a long list of automated bid strategies (target CPA, target ROAS, maximize conversions) that learn from your conversion data and run the account for you. Amazon offers three: dynamic down only, dynamic up and down, and fixed, plus placement modifiers. Amazon's automation is narrower, and most bid management on Amazon is still done by the seller or by outside tools.

Google advertisers used to handing bidding to the platform find Amazon's options thin. The gap is where third-party automation lives, and it is why the Amazon tool market is as large as it is.

Scheduling

Google has ad scheduling built in: hour and day bid adjustments in the campaign settings. Amazon does not. A Sponsored Products campaign runs 24 hours a day at one bid unless something outside the console changes it. For advertisers coming from Google, this is the single most surprising gap, and it is the reason dayparting on Amazon is a tool category rather than a checkbox.

Reporting

Google's reporting is deep, customizable, and integrated with analytics. Amazon's is adequate at the campaign level and requires downloading reports for anything at the search term, placement, or hourly level. Sellers used to Google's interface find the console sparse. The data is there; it is in spreadsheets.

What transfers

The discipline. Search term review, negative keyword hygiene, separating discovery from scale, reading conversion rate alongside cost, testing one thing at a time. Advertisers with good Google habits bring the right instincts and need to relearn the specifics.

What does not transfer: the keyword list, the bid strategies, the attribution assumptions, the restructuring reflex, and the expectation that the platform will schedule and bid for you.

Running both

Brands with Brand Registry can run Google Ads to their Amazon listings and track the result with Amazon Attribution. External traffic can help organic rank, and some categories reward it. It is also expensive: Google clicks cost more than Amazon clicks for the same term, and the shopper lands on a page with competitors on it. For most sellers, Amazon's own ads are the first and larger investment, and Google to Amazon is a later experiment.

Frequently asked questions

Is Amazon PPC easier than Google Ads?

Simpler, not easier. Amazon has fewer campaign types, no landing page to build, and no creative for Sponsored Products. But the shopper is one click from buying, the auction rewards conversion history heavily, and the margin for error is small because every click is close to a sale. Google is more complex to set up and more forgiving of a weak first month.

Can I use my Google Ads keyword list on Amazon?

As a starting point, with caution. Google searches include research and informational intent that Amazon searches mostly lack. The commercial terms transfer; the question-shaped and comparison terms usually do not convert on Amazon. Build the Amazon list from Amazon's own search term reports as soon as there is data.

Should I run Google Ads to my Amazon listing?

It can work for brands with Brand Registry, using Amazon Attribution to track the result, and it is one way to send external traffic that Amazon's ranking rewards. It is also expensive, because Google clicks cost more and the shopper lands on a page with competitors on it. Most sellers get more from Amazon's own ads first.
