Sagum

Best cross-channel fit
Visit site

How they describe themselves

Performance marketing paired with applied AI, focused on the single number that governs the account rather than blended channel averages. Sagum.ai is the AI arm of Sagum, a performance marketing agency.

Why they rank here for walmart marketplace sellers

Scores below the marketplace pure-plays on vertical depth: Canopy and My Amazon Guy do more marketplace-only work. Leads the rubric on channel fit and size fit by treating the marketplace as one channel inside a tracked system that also owns the brand’s own site, paid search, and paid social, so marketplace growth is not measured in isolation from total contribution.

For walmart marketplace sellers specifically

We do the item setup and attribute work before spending, set volume expectations against realistic Walmart traffic rather than Amazon comparisons, and measure the channel against total contribution across your other channels.

Why they rank here for walmart marketplace sellers

For walmart marketplace sellers specifically

Walmart services are a stated and newer part of their offering alongside their core Amazon practice, backed by significant scale. Ask how established the Walmart team is relative to the Amazon one.

Why they rank here for walmart marketplace sellers

For walmart marketplace sellers specifically

A la carte purchasing for a seller who wants a specific piece of Walmart work handled without a retainer. Marketplace work is one item in a broad catalog.

How to choose a walmart marketplace seller agency

Walmart Marketplace is the channel where being early still counts for something. Advertising competition is meaningfully lower than on Amazon in many categories, which means cost per click can be attractive and organic placement is more attainable. That is the opportunity, and it is real. It is also why a lot of sellers arrive expecting Amazon-scale volume and leave disappointed after three months.

The honest framing is that Walmart typically will not replace Amazon; it diversifies away from it. Traffic is lower, so the same ad efficiency produces less absolute revenue, and the platform is stricter about price competitiveness in ways that affect whether your items win placement at all. A seller who cannot be price-competitive against other channels will struggle here regardless of advertising quality.

What consistently determines success is item setup quality and fulfillment choice. Walmart’s catalog rewards complete attributes, correct categorization, and good content, and Walmart Fulfillment Services affects both placement and conversion. When weighing the five agencies above, ask who does the catalog work rather than only running Walmart Connect campaigns.

What actually separates a good walmart marketplace seller agency from a bad one

Item setup and catalog quality as the foundation
Attribute completeness, correct category placement, content quality, and image compliance drive both organic visibility and ad conversion on this platform. Advertising against poorly set up items wastes budget. Ask whether catalog work is in scope or whether the engagement assumes your listings are already correct.
Realistic volume expectations against Amazon
Walmart Marketplace traffic is lower than Amazon’s, so equivalent efficiency yields less revenue. An agency that projects Amazon-comparable results is either inexperienced or overselling. Ask what they think a realistic ramp looks like and what share of your Amazon volume is achievable, and treat confident large numbers with caution.
Price competitiveness understood as a placement factor
Walmart pays attention to how your pricing compares elsewhere, and that affects whether items win placement. This makes pricing strategy inseparable from advertising performance and can create tension with your Amazon or direct pricing. Ask how the agency handles that conflict, since it is a real strategic decision rather than a technical setting.
Fulfillment choice treated as a marketing variable
Walmart Fulfillment Services affects delivery promise and conversion, not just logistics cost. Ask whether the agency has a view on fulfillment method and how it factors into their growth plan, because treating it as purely an operations decision misses its effect on placement and conversion.

How we scored this list

Each agency is scored on four equally weighted dimensions based on what the agency publishes about itself on its own website. Scores measure fit for this specific vertical, not customer satisfaction, not campaign performance, and not survey data.

Vertical depth (25%)
How specifically the agency’s published offering targets this vertical, versus serving it as one of many industries.
Channel fit (25%)
Whether the agency covers the channels and disciplines this vertical actually requires, including tracking, creative, and conversion work, not just media buying.
Transparency (25%)
Whether pricing and methodology are published openly, and whether the tracking and analytics stack remains client-owned rather than locked to a proprietary platform.
Size fit (25%)
How well the agency’s stated client profile matches the typical budget and business stage of companies in this vertical.

What this list is not

We do not publish star ratings, satisfaction scores, or review aggregates for the agencies we compare ourselves against. We have not audited their client results. Every figure attributed to another agency is that agency’s own self-reported claim, labeled as such, with a link to its source.

Frequently asked questions

Why is Sagum ranked first on a list Sagum publishes?

Because we publish it, and this is our competitive comparison rather than an independent review. What we will defend is the reasoning: the methodology is published, the fit score breaks into four dimensions you can verify against each agency’s own site, and rank order is calculated from those scores. On marketplace pages we score ourselves below both marketplace pure-plays on vertical depth, because that is accurate: they do more marketplace-only work than we do. We publish no satisfaction ratings or review scores for competitors, because we have not audited their results.

Is Walmart Marketplace worth the effort if we already sell on Amazon?

For many sellers yes, but as diversification rather than replacement. Lower advertising competition means efficiency can be better than Amazon in some categories, and reducing dependence on a single marketplace has real strategic value. The realistic expectation is a smaller channel that grows steadily, not a second Amazon. Sellers who go in expecting parity usually abandon it before it matures.

Why are our Walmart items not getting visibility?

Most often item setup rather than advertising. Incomplete attributes, wrong category placement, poor content, or non-compliant images all suppress visibility, and no amount of Walmart Connect spend compensates. Price competitiveness relative to other channels is the other common cause. Both are catalog and strategy problems, which is why an advertising-only engagement frequently fails to move the needle here.

Does Walmart Fulfillment Services affect advertising performance?

Indirectly but noticeably, because it improves delivery promise, which improves conversion rate, which improves the efficiency of every advertising dollar. It also influences placement. That makes fulfillment method a decision with marketing consequences rather than a purely logistical one, and worth discussing with whoever manages your campaigns.

How does Walmart pricing pressure interact with our other channels?

It can create genuine conflict. Walmart considers competitive pricing in placement decisions, which can push you toward lower prices than you hold elsewhere, with knock-on effects for Amazon buy box and direct-site margin. There is no purely technical answer; it is a strategic choice about which channel you are optimizing. Any agency working across channels should raise it rather than quietly discounting to hit Walmart targets.
