    Done-for-you catalogue optimization

    Continuous Listing Optimization at Scale

    We run a done-for-you system that keeps your entire marketplace catalogue ranked, converting, and compliant – continuously.

    Your Reality

    The reality of large catalogues

    Rankings decay faster than your team can react

    One-time optimization expires within weeks

    Compliance changes suppress listings overnight

    Ad spend keeps climbing because organic positions can't hold

    Performance is inconsistent – some listings fine, others invisible

    Per-listing agencies cost $200–500+ each – unsustainable at 1,000+ SKUs

    One-time optimization does not solve a continuous problem.

    Where does your catalogue sit?

    The optimization maturity spectrum

    Most catalogues operate at level 1–3. The gap between reactive fixes and continuous optimization is where performance compounds – or decays.

    0

    Unoptimized

    Listings created from manufacturer data. No keyword research, no competitive positioning.

    1

    Initial optimization

    One-time keyword research using third-party estimates. Applied once, then left alone.

    2

    Periodic revisit

    Most sellers

    Optimization refreshed quarterly or semi-annually. Still based on estimated data, not actual performance.

    3

    Reactive fixes

    Most sellers

    Listings revisited when problems surface – ranking drops, suppressions, complaints. Always catching up.

    4

    Continuous & data-driven

    Marketplacer

    Live marketplace data feeds a system that re-evaluates and re-optimizes the full catalogue automatically. Changes compound.

    The System

    Optimization that compounds instead of expiring

    Most tools and agencies rely on third-party estimators and scraped data – they optimize on what they think is happening. We connect to the source and optimize on what is happening.

    From your marketplace data we extract Selection Signals (which listings to optimize) and Instruction Signals (how to optimize them).

    Direct API integration

    Connected to your marketplace APIs – every decision is based on real performance data: impressions, clicks, conversions, keyword rankings, Buy Box status, and suppression flags.

    Continuous feedback loop

    Every change is measured against actual results. What works scales. What doesn't gets revised. Optimization compounds instead of expiring.

    Catalogue-wide prioritization

    The system automatically identifies and targets the highest-value opportunities across your entire catalogue – not just the listings you happen to notice.

    If optimization doesn't feed back into itself, it expires.

    Continuous optimization system – data collection, analysis, strategy, execution, and performance feedback loop

    The impact

    What continuous optimization delivers

    Organic ranking growth

    Listings climb naturally as the system continuously optimizes for marketplace algorithms – reducing the need to buy visibility.

    PPC cost efficiency

    Stronger organic positions mean lower cost-per-click, better ACOS, and less ad spend required to maintain sales velocity.

    Conversion rate improvement

    Every listing element is optimized against real buyer behavior data – titles, bullets, images, and A+ content all working harder.

    Compliance & suppression protection

    Automated monitoring catches policy violations and listing suppressions before they impact revenue.

    Built for catalogue-scale operators

    This is for you if you

    • Manage 1,000+ active listings across marketplaces
    • Operate in competitive categories where ranking matters
    • Need a repeatable system, not freelance rewrites
    • Think long-term about catalogue performance

    Not the right fit if you

    • Want a one-time optimization pass rather than an ongoing system
    • Have a small catalogue (under ~500 listings) where continuous optimization isn’t yet the priority
    • Choose partners mainly on lowest price instead of long-term ROI
    • Expect listings to stay effective without ongoing data, feedback, or updates

    The Process

    Getting started

    Every engagement starts here

    Suitability Scanner

    Free catalogue audit to confirm system-fit. No listing changes. No commitment. Go/no-go.

    Three operating states. One system.

    Once confirmed, the system progresses through three states based on your catalogue's needs.

    State 1

    System Stabilizer

    ~3 months

    We integrate with your marketplace APIs, remove structural blockers, and validate optimization on a limited scope.

    State 2

    Catalogue Compounder

    Ongoing

    Continuous re-optimization across the full catalogue based on live performance signals. The compounding engine.

    State 3

    Dominance Driver

    Enterprise

    Maximum optimization intensity. Custom strategy, priority response, dedicated resources. For catalogues where market leadership is the goal.

    Limited offer until end of month

    Validated results in 30 days.
    Or your $500 back.

    We are not asking for a commitment. We are asking for 30 days to prove what the system does on your catalogue. If we cannot show measurable, validated results, we refund every cent. No conditions. No friction.

    What month one includes

    • Full catalogue diagnostic delivered within 48 hours of API connection
    • System connected directly to your live SP-API data, no third-party tools, no estimates
    • First optimization opportunities identified, validated against real performance data
    • Changes executed and tracked against your pre-engagement baseline
    • A precise picture of what continuous optimization means for your specific catalogue

    No results? Full refund. No questions.

    If we do not validate a clear, measurable optimization opportunity on your catalogue within 30 days, you get your $500 back in full. No conditions, no admin, no waiting.

    No contract. Cancel any time after month one.

    There is no lock-in. After 30 days, you decide: continue as a retained client, or walk away and keep everything we found. The choice is yours.

    We offer this because we have run the system enough times to know what it finds. We have never had to issue this refund. We do not expect to start.
