How Amazon is Reshaping the PPC Landscape

Did you hear about Amazon pulling out of Google Shopping Ads? As the saga continues it’s tempting to focus on who did what, and when. But the real question is, what does the significance of this move mean for you as a PPC marketer?

Over the last decade or so, Amazon has been evolving from a pure e-commerce retailer into a major digital ad platform that competes for intent-driven spend alongside Google and social channels.

But these recent moves from Amazon have revealed their enormous impact on the modern world of e-commerce. We’re here to help clarify that significance, and point you in the right direction when it comes to fortifying your Shopping campaigns, and preparing for the future of e-commerce.

Amazon Shopping Ads: What are they and what did they do?

Amazon abruptly paused Google Shopping activity across many international domains and then resumed Shopping ads outside the US one month later, signalling deliberate testing of channel strategy.

Currently, Amazon’s ad model combines product listing ads, sponsored brand ads and retail media placements that target user purchase intent. This is different from search engine ads that target query intent and social platforms that often target interest or demographic signals.

But here’s the thing; because of Amazon’s Integration of merchant and seller inventory, fulfilment signals and product detail pages, their ad placements are tied directly to commerce conversion funnels. So their influence on the wider PPC landscape cannot be overstated.

Amazon’s ad footprint is large enough that its participation or withdrawal has a huge impact on Shopping ads and the wider PPC world.

How Amazon is changing the landscape for retail advertisers

So what are the actual noticeable impact elements of Amazon’s influence? The answer lies in the details of digital shopping campaigns.

Auction mechanics and competitive pressure
Amazon’s participation alters the overall landscape of shopping auction composition due to their sheet scale. A large, aggressive bidder like Amazon increases competition and can raise CPCs and influence impression shares. If Amazon decides to lift their CPC by 0.001% overall, you would see a similar shift overall for non-Amazon shopping campaigns, just to keep up and retain visibility.

On the flip side, when Amazon exits auctions, available impressions and clicks can shift to other retailers.

Impacts on bidding, CPC and cost structures
There are also a few short-term effects for other retailers. Amazon’s momentary dip from the shopping landscape resulted in a reduction in CPC but also possible fall in return on ad spend (ROAS) for some marketers. It hasn’t been confirmed yet, but there’s a chance that Amazon’s pull may have removed a high-intent, efficient traffic source from the broader funnel.

With your own campaigns, bidding strategies must be more dynamic. You should monitor impression share, CPCs and average order value closely during any competitor fluctuations and be ready to reallocate budgets.

This, and potential future Amazon fluctuations could be an opportunity for savvy marketers when Amazon reduces their spend. A pause like that is useful for testing campaigns, capturing market share and experimenting with keyword or product bidding strategies.

How this is influencing Google and other PPC platforms

This is more than just Amazon showcasing their power, it’s a wake up call for marketers everywhere.

Short-term auction and marketplace effects
Amazon’s removal from Google Shopping auctions produced measurable shifts in clicks, CPCs and ROAS for competing retailers; its selective re-entry demonstrates that Amazon can flex buying power to test channel dependence and cost of acquisition for independent marketers. 

Google and other platforms may see a short revenue impact in the wake of Amazon reducing spend, which could prompt marketplaces to reassess product listings, bidding thresholds and auction features.

Advertiser behaviour and platform responses
Some advertisers may diversify spend faster, splitting budgets between retail media, direct search and social channels to reduce single-platform risk. This could be the wake up call some marketers needed when it comes to putting all their eggs in one basket.

We predict that agencies and platform partners will prioritise cross-channel attribution and measurement to understand where shoppers come from when large players cycle in and out of auctions.

Platforms might respond with product or policy changes to protect auction efficiency or to encourage return of large advertisers, so watch this space!

Data, targeting and consumer rights: Amazon’s advantage

Beyond their sheer size and scale, Amazon has a few advantages that it pays to understand as a digital marketer.

First-party shopper data as a competitive moat
Amazon holds extensive first-party shopping signals, including product views, add-to-cart events, purchase history and fulfilment preferences. These help produce highly precise targeting for conversion-oriented ads and contain a level of detail that can be hard to replicate as a smaller campaign on Google Shopping.

This first-party shopper dataset gives Amazon an edge over traditional search ads that rely on query intent and over social platforms that analyse potential user intent from engagement signals. In short, it’s often easier to accurately predict audience behaviour from first-party data.

Implications for targeting precision and privacy
Higher targeting precision increases ad relevance and conversion rates for advertisers using Amazon inventory, raising the value of retail media placements overall.

The concentration of first-party retail data raises questions about attribution transparency, data portability and consumer rights. 

Opportunities for small vs. large advertisers

Benefits for large advertisers
If you’re a larger advertiser, you can use your scale to weather auction volatility, run multi-market tests and absorb short-term CPC increases. At the same time, you can protect your margins with operational levers such as negotiated placements and larger data teams.

When Amazon withdraws from a market, big brands can more easily increase their share of placements quickly and test high-investment campaigns.

Benefits and constraints for small advertisers
If you’re a smaller advertiser, you’ve potentially gained opportunities during Amazon’s downtime to capture cheaper visibility and test product demand without being outbid by Amazon.

However, you may struggle to compete when Amazon returns due to lack of scale, less sophisticated bidding automation and limited access to first-party shopper insights.

Your product category matters: niche, differentiated items often fare better against Amazon’s mass assortment than widely available, every-day goods where Amazon’s scale and logistics dominate.

Lessons from recent experimentation

The recent era of experimentation across shopping as a result of Amazon's actions has led to some useful findings.

Strategic pausing and testing as a tactic
Amazon’s abrupt withdrawal was interpreted as a deliberate test rather than an error, illustrating how a major platform can strategically pause spend to observe and learn from competitive reactions. 

Industry reactions framed the pause as an opportunity for competitors to measure incremental share and for Amazon to evaluate the dependence on external traffic sources.

International rollouts and selective market decisions
Amazon’s restart of Google Shopping ads on international domains (while excluding the US) demonstrates selective, market-level experimentation and shows Amazon’s willingness to tailor channel strategy by geography. It’s a show of a more targeted strategy that is specific to countries, not just industries.

Key take aways for marketers
Treat large platform behaviour as data. Expect selective rollouts, regional tests and rapid changes. Adapt your plans to local auction realities rather than assuming the effects will be the same globally. As ever, flexibility is the ultimate protection against market fluctuations.

Preparing for the future of ecommerce advertising

Looking into the future of shopping campaigns, taking everything we have learnt from Amazon’s recent actions, here are a few pointers to set you on the right path.

Tactical recommendations for advertisers
Invest in cross-channel measurement and attribution to retain vital data when big players such as Amazon change direction.

Build bidding rules that detect competitor exits/entries and automatically adjust spend, focusing on margins and lifetime value rather than clicks alone. This can help prevent wasted ad spend when competitors update their strategy, and allows you to funnel more of your budget where it counts.

Prioritise your business-owned channels and first-party data capture to reduce reliance on any single paid channel. This first-party data collection is invaluable for future-proofing your business, too.

Strategic predictions and trends
We predict that shopping ads will continue to grow as a distinct ad channel, with Amazon setting benchmarks for conversion-oriented buying and measurement.

Major retailers will increasingly use selective market shutoffs and targeted re-entries as experiments to understand channel elasticity, forcing advertisers to become more agile. Amazon has set a benchmark here, so expect similarly sized companies to follow suit.

Expect intensified regulatory and industry scrutiny about first-party retail data use, attribution transparency and consumer choice as targeting precision deepens. Once again, we feel that consensual first-party data collections hold a lot of the answers for the future.

Closing thoughts

Amazon isn’t just playing the tried and tested game of PPC, it’s rewriting the rules as it goes. After pulling the plug on Google Shopping with almost no warming, it quietly slipped back into international markets outside of the US and has left many still analysing what it all means for PPC.

This is a strategy that shows the influence and power that Amazon has over the PPC Shopping market globally, and the lesson for marketers is simple: don’t get comfortable.

By building flexibility and agility into your campaigns, and not being afraid to source your data sets from a more diverse range of sources, you’ll be arming yourself against future shifts in the market. As ever, the most informed and flexible marketers are the ones who will come out on top.
