Managing Amazon PPC campaigns with clear impact tracking and cross-marketplace support is difficult for sellers, brands, and agencies. Most available tools require manual spreadsheet tracking, lack detailed recommendation explanations, or delay onboarding for teams switching vendors. This comparison details pricing, automation features, and reporting tools across three competitors so teams can pick the best fit for their budget and workflow.

Selloop.ai
At a Glance
Tracks campaign changes and measures their impact over 21 days to show whether edits actually move performance without a spreadsheet. The tool pairs those measurements with line level explanations so you see why a recommendation should work. It also harvests high performing keywords from auto campaigns and supports Amazon marketplaces in Europe and North America.
Core Features
Deep campaign analysis surfaces wasted spend and suggests specific bid or keyword changes, and each recommendation includes a clear explanation tied to the underlying metrics. The platform offers configurable AI profiles for conservative, balanced, or aggressive strategies, and it automatically harvests high performers from auto campaigns. A central dashboard reports health scores, critical alerts, and a visual next steps view to prioritize fixes.
Key Differentiator
Selloop.ai links every recommendation to a causal explanation and then measures the actual result over 21 days without requiring you to build spreadsheets. That combination helps you judge whether a suggested bid or keyword edit produced the expected lift or simply moved spend.
Pros
The platform provides detailed explanations for each recommendation, so you understand which metric will change and why. It tracks edits for 21 days and reports the measured impact, removing guesswork from short term optimization. Multi marketplace support for Amazon in Europe and North America lets agencies and sellers apply the same workflow across accounts. AI profiles let you match risk tolerance to strategy, and automatic keyword harvesting reduces manual keyword discovery.
Cons
- Automatic account modifications are not yet fully available, so some changes still require manual execution.
Notable Integrations
Selloop.ai connects directly to the Amazon Ads API to pull campaign and search term data. That integration feeds its recommendation engine and the 21 day tracking, so performance reporting reflects live account data.
Who It’s For
Solo Amazon sellers who want clearer reasons behind PPC recommendations will find the platform useful. Small brands with moderate ad budgets benefit from the automated harvest and the impact tracking. Marketing agencies managing multiple Amazon accounts will value cross marketplace reporting and the ability to compare post-change results across clients.
Unique Value Proposition
Automatic harvesting of high performing keywords from auto campaigns ties directly to measured outcomes over 21 days, so your keyword list and its measured ROI appear in the same workflow. That approach reduces hours spent on separate audits and lets you confirm whether bid or keyword changes actually lower ACoS before scaling them across accounts.
Real World Use Case
Selloop.ai reports a 20% reduction in ACoS for a small seller who used the platform to identify underperforming campaigns and optimize bids toward high conversion terms. The 21 day tracking then confirmed the improvement, allowing the seller to scale the same changes across similar listings.
Pricing
Plans start at €29 or $29 for the Starter plan, which covers up to €1,500 in managed spend. Higher tiers are available for larger budgets and include agency features and expanded account support.

atom11
At a Glance
Atom11 reports most brands see PPC improvements within two weeks. The platform merges ads, inventory, pricing, and competitor signals into a single dashboard for Amazon PPC management. It targets individual sellers, growing brands, agencies, and large catalog accounts.
Core Features
Core capabilities include Bid Optimization, a Root Cause Analyzer, dayparting, and an AI assistant called AI Copilot Neo. The platform also supports version control, performance insights, keyword harvesting, custom reporting, search term negation, and digital shelf tracking. Extensive automation rules and built in testing let teams run experiments without spreadsheets.
Key Differentiator
Atom11’s marketing materials state it is the only Amazon PPC tool that combines retail signals like inventory and pricing data with ad automation. That retail aware approach aims to change bids based on stock levels and competitor pricing rather than ads alone. For sellers who manage promotions or face supply constraints, that linkage can change how spend is allocated across SKUs.
Pros
The main strength is the integrated data model that links inventory and pricing to ad decisions. Retail aware bid automation can reduce wasted spend when stock runs low or when competitors change price. The product also offers rule testing, version control, and a clear analytics interface that reduces day to day manual tracking.
Cons
- Public feature and integration pages return errors, which makes evaluating technical fit harder.
- External sentiment about performance and support is reported as largely negative on third party sources.
- Pricing can be expensive for larger ad spends, and enterprise customers must request custom quotes.
When It May Not Fit
If you need public documentation of integrations or a transparent API, atom11 may not fit. Large enterprises that require clear third party ratings or formal SLAs should be cautious. Small margin sellers with tight budgets may find the Professional tier hard to justify.
Who It’s For
Amazon sellers, brands, and agencies that want bidding driven by retail signals will get the most value. Teams that run frequent promotions or manage seasonally constrained stock benefit from dayparting and retail aware bids. Agencies managing many client accounts can scale rules and tests across portfolios.
Real World Use Case
A mid sized seller automates bid and keyword optimization while monitoring performance in one place. That setup matched the claim about two weeks for initial improvements and helped the seller shift spend away from unprofitable SKUs. The combined reporting reduced time spent reconciling ad and inventory reports.
Pricing
Plans start at $499/month for ad spend up to $50K. The Professional tier is $1,199/month for $50K–$500K in ad spend. Enterprise pricing is custom for larger budgets and requires a sales consultation.
Website: https://atom11.co
Core Features
Perpetua centers on AI-powered bid optimization, automated keyword harvesting, and in-depth performance reporting that ties ad spend to profitability. The platform issues data-driven recommendations, and supports hourly reporting for higher tiers via Amazon Marketing Stream. Reporting and market intelligence work across multiple marketplaces, so brands can compare performance by channel.
Xnurta
At a Glance
Xnurta reports its AI makes over 2 million decisions daily, a claim that signals heavy automation for large accounts. The platform targets brands and agencies running retail media across Amazon, Walmart, and Criteo. It pairs continuous machine learning with multi account controls to reduce manual campaign work.
Core Features
Xnurta combines AI powered bid, budget, and targeting optimization with a unified view of Sponsored Ads, DSP, and AMC. The platform supports campaign creation, automation, and reconstruction using machine learning, and adds advanced reporting and market analysis. Enterprise customers get onboarding support and dedicated customer success resources.
Key Differentiator
The product’s main distinction is continuous AI optimization across multiple retail channels in one console. That single workflow lets teams apply the same optimization logic to Amazon, Walmart, and Criteo campaigns without switching tools. The unified approach aims to keep cross-network budget and targeting aligned while reducing repetitive tasks.
Pros
Xnurta automates repetitive bid and budget adjustments, which frees media teams to focus on strategy. It supports multi network management including Amazon, Walmart, and Criteo, so agencies can consolidate accounts under one roof. Enterprise customers receive onboarding and dedicated success managers, which helps larger teams get campaigns running and scale efficiently. The vendor also highlights industry recognition for full funnel advertising and storytelling.
Cons
-
Setup can be slow and problematic according to multiple user reports. Implementation delays have blocked fast launches for some teams.
-
Cancellation policies are described as rigid, and users report poor responsiveness from support after they request cancellations. That creates friction for teams changing vendors.
-
Campaign performance shows variability in customer feedback, with some accounts seeing inconsistent results after launch.
When It May Not Fit
Small brands with limited budgets will likely find the platform expensive for early-stage retail media. Teams that need fast, simple onboarding may struggle with the reportedly slow setup process. Organizations that require guaranteed, consistent performance under short timelines should test a pilot before committing.
Who It’s For
Serious retail media teams at brands and agencies managing substantial ad budgets will benefit most. The platform fits groups that need multi account controls and want to centralize Amazon, Walmart, and Criteo campaigns. It also suits teams willing to invest in enterprise onboarding and support.
Real World Use Case
A retail brand consolidates Amazon Sponsored Ads, DSP, and Walmart campaigns into Xnurta to reduce manual reporting. The brand uses the platform to rebuild underperforming campaigns with AI driven automation and to free up the media team for SKU level merchandising work. Reporting time drops and manual adjustments become less frequent.
Pricing
Pricing starts from $750/month or 3% of ad spend for brands managing up to $80k/month. The vendor provides custom pricing for higher spend levels. Enterprise onboarding and dedicated success support are available under those commercial terms.
