Amazon PPC has become too granular to run well by hand once a catalog has more than a handful of SKUs — bids need to move by the hour, keywords need to be harvested and negated continuously, and a target ACoS only holds if someone (or something) is actually watching it. AI bidding tools exist to do that continuous adjustment automatically, freeing you to set the strategy instead of babysitting bids. We looked at the tools Amazon sellers actually rely on for this, from enterprise-grade platforms to lower-cost automation.

Quick comparison

1. Perpetua — best for full-funnel automation at scale

Perpetua's AI sets and adjusts bids toward a goal you define (target ACoS, target ROAS, or a growth objective) across Sponsored Products, Sponsored Brands, and Sponsored Display, and extends the same automation to Walmart and Instacart if you sell there too. For a seller managing ad spend across marketplaces rather than just Amazon, it's the most complete platform we tested. Try Perpetua. If you're deciding between Perpetua and Teikametrics specifically, our Perpetua vs Teikametrics for Amazon PPC automation comparison breaks down which fits a single-marketplace seller versus one managing spend across Amazon, Walmart, and Instacart at once.

Pros: true full-funnel, cross-marketplace automation; strong reporting on what's actually driving spend. Cons: priced for sellers with meaningful ad budgets already, and the tiers step up quickly as managed spend grows.

2. Teikametrics — best AI-managed bidding with the easiest on-ramp

Teikametrics' Flywheel 2.0 engine adjusts keyword and placement bids continuously toward a target ACoS, without requiring you to build the automation rules yourself the way some cheaper tools do. It's also one of the few tools here with a genuinely useful free tier for brand-new sellers still under a low spend threshold, which makes it the natural starting point before you know whether you need a heavier platform. Try Teikametrics.

Pros: free entry point for new sellers, bidding automation that works well without heavy manual configuration. Cons: the free and lower tiers cap out fast — growing sellers move into paid pricing quickly, and larger accounts can shift to a percentage-of-spend model.

3. Helium 10 Adtomic — best if you're already in the Helium 10 ecosystem

Adtomic bundles AI-assisted bid automation, keyword harvesting, and campaign structuring inside Helium 10's broader suite, alongside the product and keyword research tools covered in our best AI keyword research tools for Amazon sellers guide. For a seller who's already paying for Helium 10's Diamond plan for research, Adtomic's PPC automation is close to a free add-on rather than a new line item. Try Helium 10.

Pros: no separate subscription if you already use Helium 10 for research; keyword data and bid automation share the same account. Cons: it's bundled into a higher Helium 10 tier, so it's a poor fit if PPC automation is the only feature you need.

4. Trellis — best lower-cost full automation

Trellis applies machine-learning bid automation across Sponsored Products, Brands, and Display at a starting price meaningfully below Perpetua or Sellozo, aimed at sellers who want genuine automation without an enterprise-size budget. Try Trellis.

Pros: real ML-driven bidding at a lower entry price than most full-automation platforms. Cons: smaller company than Perpetua or Teikametrics, so the reporting and integration ecosystem is less mature.

5. Sellozo — best flat-fee pricing with no percentage of spend

Sellozo prices flat per marketplace rather than taking a cut of managed ad spend, which makes costs predictable as your spend grows — a real advantage over percentage-of-spend tools once you're managing a large budget. It also offers an optional fully-managed service if you'd rather hand PPC off entirely. Try Sellozo.

Pros: flat, predictable pricing regardless of spend; managed-service option available. Cons: per-marketplace pricing adds up quickly if you sell across more than one, since each one is billed separately.

6. Ad Badger — best for smaller ad budgets

Ad Badger pairs lighter-weight bid automation with genuinely useful educational content and lower entry-level pricing, making it a reasonable starting point for a seller with a few thousand dollars a month in ad spend rather than tens of thousands. Try Ad Badger.

Pros: accessible pricing for smaller sellers, strong free educational resources alongside the paid tool. Cons: less depth than the enterprise-focused platforms once your catalog and ad spend scale up significantly.

How to choose

• You sell on more than one ad platform (Amazon, Walmart, Instacart): Perpetua, for automation that spans all of them from one dashboard.
• You're a newer seller and want to try AI bidding without committing: Teikametrics, for the free tier and the easiest setup.
• You already pay for Helium 10: Adtomic, since the PPC automation is close to a sunk cost you're not using yet.
• You want ML-driven bidding without enterprise pricing: Trellis.
• Your ad spend is large enough that a percentage-of-spend fee would sting: Sellozo, for flat per-marketplace pricing.
• You're managing a modest budget and want guidance, not just automation: Ad Badger.

None of these tools fix a weak listing — automated bidding optimizes toward whatever target you set, and a bad target (or a listing with a poor conversion rate) just gets automated faster. Before turning any of these loose, it's worth reading Amazon's own getting started guide for Sponsored Ads if you haven't run PPC before, so you understand what the automation is actually adjusting. And if pricing — not ad spend — is where you're leaking margin, our best AI tools for Amazon FBA sellers and best Amazon repricing tools roundups cover the other half of the profitability equation that ad automation alone won't solve. Sellers running Amazon PPC alongside Google Shopping should also see our best AI tools for Google Shopping ads optimization roundup, since feed and bid automation on that channel work on the same underlying logic as the tools above.
