BidX

What is BidX?

BidX is an AI-driven PPC automation platform for Amazon and Walmart sellers, founded in 2018 by former Amazon sellers and computer scientists in Darmstadt, Germany. The platform automates the most time-consuming parts of marketplace advertising — keyword bidding, negative-keyword harvesting, budget allocation across portfolios, dayparting, and campaign restructuring — using algorithmic rules and machine-learning models trained on retail-specific data. According to the company, BidX manages over $300M in annual ad spend and influences roughly $3B in marketplace GMV across thousands of seller accounts.

BidX targets a different buyer than typical Amazon software. Helium 10 and Jungle Scout sell to sellers who need product research, listing optimization, and reviews. BidX assumes you already have winning products and need to scale advertising without hiring three more PPC managers. The product covers Amazon Sponsored Products, Sponsored Brands, Sponsored Display, Amazon DSP (display and video), Amazon Marketing Cloud reporting, and Walmart Connect Sponsored Products. Bid strategies are configurable: ACOS-based, ROAS-based, share-of-voice, new-product launch, and seasonal-event pacing (Prime Day, Black Friday, Q4 holiday). The platform also harvests negative keywords automatically — flagging search terms that spend without converting and adding them to negatives at the campaign or ad-group level.

BidX sells in three tiers. Self Service Platform (€495/month + percentage of connected ad spend) is for in-house teams who want the software but run their own strategy. Managed Platform (€1,995/month + % of ad spend) is the recommended hybrid: software plus up to two monthly strategy calls and 10 hours of operational assistance from a Growth Manager. Managed Service (€4,995/month + % of ad spend) is fully outsourced — BidX strategists run the account, and you get up to four monthly calls and 32 hours of assistance. Amazon DSP automation is a separate add-on starting at €495/month, and Amazon Marketing Cloud default reports are €295/month. The minimum threshold for the standard tiers is around €10,000/month in ad spend; smaller sellers are routed to a lower-tier "Essentials" solution. There is no free product tier, but BidX offers a free PPC audit with competitor benchmarking.

BidX Pricing (Verified May 2026)

All BidX plans are billed monthly with annual commitment, in EUR or USD. Pricing is shown net (VAT added where applicable). Source: bidx.io/en/pricing.

Important pricing notes:

• All paid tiers add a percentage of connected ad spend on top of the platform fee — the exact percentage is negotiated based on monthly spend volume.
• Annual commitment is required, but invoicing is monthly.
• Sellers spending less than €10,000/month on Amazon ads should ask about the lower-tier Essentials plan rather than Self Service.
• BidX offers a free PPC audit — a custom evaluation by their advertising experts with competitor benchmarks. Treat this as a sales-qualification step, not a free trial of the software.
• Walmart Sponsored Products automation is included in standard Amazon plans where the seller has both connected.

Key Features

• Algorithmic bid optimization — sets keyword and product-targeting bids per ASIN based on conversion rate, ACOS target, dayparting signals, and seasonality. Runs as often as every hour on high-spend campaigns.
• Automated negative-keyword harvesting — search-term reports are scanned continuously; terms that spend without converting are added to negatives at the campaign or ad-group level using configurable thresholds (e.g., €X spent, 0 orders in 14 days).
• Budget allocator — redistributes daily budgets across portfolios and campaigns based on yesterday's pacing, target ACOS, and remaining month-to-date spend.
• Amazon DSP automation — separate module for Sponsored Display and DSP audiences (in-market, lifestyle, lookalike, retargeting). Includes custom audience creation, frequency capping, and creative rotation rules.
• Amazon Marketing Cloud (AMC) reports — pre-built and custom queries on AMC clean rooms for cross-channel attribution, new-to-brand metrics, and customer-journey analysis.
• Walmart Connect support — Sponsored Products automation on Walmart with the same bid algorithm, sharing one dashboard with Amazon performance.
• ChatGPT-powered campaign suggestions — AI-generated keyword expansions, ad-copy variants for Sponsored Brands, and structural recommendations for new launches.
• Campaign audit tool — diagnostic that flags duplicate keywords, cannibalized targeting, runaway ACOS campaigns, and missed search-term opportunities.
• Share-of-Voice tracking — paid + organic ranking position on any tracked keyword across Amazon's first SERP, with daily snapshots and competitor benchmarks.
• Multi-account / agency console — single login across dozens of seller accounts, white-label client reporting, and role-based access for agencies managing brands.
• Strategy calls and Growth Manager assistance — Managed and Managed Service tiers include named human consultants who review accounts, set goals, and configure rules.

Pros & Cons

Best For

Mid-market Amazon brands ($1M–$50M GMV) spending €10K+/month on Sponsored Ads who have outgrown Helium 10 Adtomic and want a bid algorithm trained on real ad-spend data rather than rule templates. Amazon-and-Walmart multichannel sellers who want one dashboard rather than juggling Pacvue for one and Sellozo for the other. Performance agencies managing 5–50+ seller accounts who need white-label reporting, role-based access, and a Growth Manager partnership for client services. Brands running Amazon DSP who want display, video, and Sponsored Display managed from the same console as Sponsored Products — most competitors treat DSP as a separate product. European Amazon sellers serving DE/UK/FR/IT/ES marketplaces where US-centric tools sometimes lag on local feature parity.

BidX vs the Amazon PPC field

The Amazon advertising tool category has split into three sub-segments. Understanding which one BidX competes in is the difference between buying the right tool and the wrong one.

BidX vs Helium 10: Different products. Helium 10 covers product research, listing optimization, keyword databases, and reviews — Adtomic is one module of many. BidX has none of that, but its bid algorithm is more sophisticated and its hybrid service model lets you bring in human strategists. Most serious sellers run both: Helium 10 for everything that isn't bidding, BidX (or a similar specialist) for the ad account.

BidX vs Perpetua: Closest direct competitor. Perpetua leans enterprise — share-of-shelf strategies, more retailers (Instacart, Target, Criteo), heavier reporting layer. BidX leans mid-market with deeper agency tooling and a stronger European footprint. Pricing on both is opaque and negotiated.

BidX vs Teikametrics: Teikametrics' Flywheel is the closest like-for-like algorithm — both target Amazon + Walmart Sponsored Ads with goal-based optimization. Teikametrics is friendlier for sub-€10K/mo spenders; BidX wins on DSP and the included Growth Manager partnership. If your monthly ad spend is under €10K, start with Teikametrics; over €25K, BidX's service tiers make more sense.
