AppSpike vs Amazon Publisher Services

Amazon APS is one demand source via header bidding. AppSpike is 29 networks competing in a neutral auction with on-device optimization.

Feature Comparison

The Core Problem with Amazon Publisher Services

Amazon Publisher Services is a single demand source, not a mediation platform. Using APS alone means every impression is filled by Amazon buyers only — there's no competition from other networks, no broad auction pressure, and no way to know if a non-Amazon bidder would have paid more.

APS is designed to be integrated alongside other ad networks and mediation layers. But managing that integration yourself means maintaining multiple SDKs, configuring waterfall priorities, and manually balancing demand — with no unified optimization across sources.

AppSpike includes Amazon Publisher Services as one of 29 competing networks. Amazon's demand still competes for every impression — but now it has to win against AdMob, AppLovin, Meta, Unity, Chartboost, and 23 other networks in a real-time auction.

What Doesn't Change When You Switch

You don't lose Amazon's demand. You keep it.

• Your Amazon Publisher Services account stays active
• Amazon continues to compete for impressions through the AppSpike adapter
• Amazon DSP and Transparent Ad Marketplace demand keeps flowing
• The difference: Amazon now competes alongside 28 other networks — and only wins when it's the highest bidder

Where Amazon Publisher Services Falls Short

1. Single Demand Source

APS connects you to Amazon buyers only. High CPMs from Amazon advertisers are valuable, but one demand source means no auction pressure from competing networks. AppSpike connects 29 demand sources into a single real-time auction. More bidders means higher eCPMs — even on impressions Amazon would have won anyway, because the competitive pressure raises bids.

2. No Inventory Intelligence

APS shows ads where you place them, when you trigger them. It doesn't optimize what type of ad to show, when to show it, or how often. AppSpike's optimization engine analyzes real signals — eCPMs, fill rates, user behavior — to optimize ad timing, frequency, and format per session.

3. No Mediation

APS is not a mediation platform. It's a header bidding SDK that must be integrated alongside a separate mediation solution. This means you need to manage multiple SDKs, configure waterfall rules, and handle the complexity yourself. AppSpike provides full mediation with Amazon as one of 29 competing networks — all through a single integration.

4. Category-Dependent Fill

Amazon's demand is strongest in e-commerce-adjacent categories. If your app isn't in shopping, deals, or product-related verticals, APS fill rates drop significantly. AppSpike fills 98%+ of impressions across all verticals by routing to whichever of 29 networks has the best bid for each impression.

5. No On-Device Optimization

APS has no on-device optimization layer. It doesn't pre-load ads based on session signals, doesn't adapt to user behavior, and doesn't optimize delivery timing. AppSpike's on-device model evaluates connection quality, session depth, and placement history to trigger pre-fetching at the right time — so ads are ready without letting high-value bids expire.

Revenue Impact

Publishers that switch from APS-only to AppSpike typically see:

The lift comes from three places: demand competition across 29 networks instead of one, smarter ad timing through on-device optimization, and fewer missed impressions through predictive pre-loading.

Migration Path

AppSpike replaces your ad layer, but keeps Amazon competing for impressions:

1. Add the AppSpike SDK and adapters for each ad network you want to compete (including Amazon Publisher Services)
2. Initialize with your App ID
3. Replace APS ad load calls with AppSpike.loadInterstitialAd(), AppSpike.loadRewardedVideoAd(), etc.
4. Amazon continues to compete — it just has to win the auction against 28 other networks now

When Amazon Publisher Services Alone Makes Sense

If your app is in a heavily e-commerce-adjacent category with under 1,000 DAU and Amazon consistently delivers the highest CPMs in your market, keeping APS as your sole demand source may be simpler. APS is also reasonable if you already have a mediation setup and are evaluating whether to add Amazon as an additional demand source — in which case, AppSpike already includes APS as one of its 29 networks.

For everyone else — any app with meaningful ad inventory across diverse user segments — adding full mediation through AppSpike is a straightforward revenue upgrade.

Bottom Line

Amazon Publisher Services delivers strong CPMs from Amazon advertisers, but relying on one demand source means you're leaving money on the table. AppSpike lets you keep Amazon's demand while adding 28 more competing networks, on-device optimization, and a unified analytics dashboard — all in under an hour.
