#1

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 ebay 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 ebay sellers specifically

We treat ad rate as a per-listing margin decision rather than an account-wide setting, react to inventory that turns over, and measure eBay against your total contribution rather than as an isolated channel.

Canopy Management

Deepest marketplace operations
Visit site

How they describe themselves

A full-service marketplace agency focused on Amazon, with Walmart and Shopify support, covering both advertising and day-to-day account operations.

Why they rank here for ebay sellers

Top vertical depth on this list: Amazon-first since 2015 with Walmart and Shopify support, covering advertising plus the operational layer: listings, inventory, reimbursements, photography. Channel fit scores lower because owned-site paid search and paid social are secondary to the marketplace.

For ebay sellers specifically

The deepest marketplace operations capability here, though their published focus is Amazon first with Walmart and Shopify support, so confirm how much genuine eBay experience the team assigned to you has.

My Amazon Guy

Highest Amazon volume
Visit site

How they describe themselves

A high-volume Amazon growth agency covering PPC, SEO, design, and platform management for Seller Central and Vendor Central, with newer Walmart and DTC services.

Why they rank here for ebay sellers

Equally deep Amazon specialization at high volume, spanning Seller Central and Vendor Central with newer Walmart and DTC add-ons. Size fit scores slightly lower than Canopy’s because the stated client range spans individual FBA sellers to enterprise brands at a high client-to-team ratio.

For ebay sellers specifically

Very high marketplace volume and strong listing and case-management capability, but the published practice centers on Amazon and Walmart. eBay is not named among their platforms, so ask directly.

Things to weigh before signing

Tinuiti

Widest channel coverage
Visit site

How they describe themselves

A full-funnel media agency spanning commerce, streaming and linear TV, social, and search, organized around its "Bliss Point" marketing operating system.

Why they rank here for ebay sellers

The widest channel surface of anyone here: commerce media, retail media, CTV, search, and social under one roof. Size fit is the lowest score in this lineup: the practice is enterprise-weighted, with midsize brands routed to a separate tier.

For ebay sellers specifically

Broad commerce media capability across marketplaces and retail media at enterprise scale. Size fit is the constraint for most eBay sellers, since the core practice is enterprise-weighted.

Hawke Media

Most flexible to buy
Visit site

How they describe themselves

Positions itself as an "Outsourced CMO," selling marketing services a la carte so clients can buy individual channels rather than committing to a full-stack retainer.

Why they rank here for ebay sellers

Offers Amazon services within a 23-plus service catalog sold a la carte. Vertical depth scores lower because marketplace work is one line item rather than the core practice, and the a la carte model means cross-channel strategy is generally bought separately.

For ebay sellers specifically

The a la carte model suits a seller who wants one specific piece of work done without a retainer. Marketplace work is one line item in a wide catalog rather than a specialty.

How to choose a ebay seller agency

eBay is the marketplace most agencies quietly do not want to work on, and that is worth knowing before you hire one. The catalog logic is looser than Amazon, a large share of inventory is used, refurbished, or one-of-a-kind, and Promoted Listings behaves differently from a keyword auction. Agencies whose entire playbook is Amazon Sponsored Products tend to arrive, apply it, and produce mediocre results.

The thing that actually governs eBay economics is sell-through against ad rate. Promoted Listings Standard charges you a percentage of the sale rather than per click, which means the calculation is not cost per acquisition in the usual sense; it is a margin decision made per listing, at scale, across inventory that may be constantly changing. An account managed as though it were pay-per-click will systematically over-promote slow inventory and under-promote what is already moving.

Seller reputation is also load-bearing here in a way it is not everywhere. Feedback percentage, Top Rated Seller status, and shipping performance affect visibility and conversion directly, which makes operations part of your marketing performance. When weighing the five agencies above, ask who understands ad rate as a margin lever and who treats eBay as its own system rather than Amazon with a different logo.

What actually separates a good ebay seller agency from a bad one

Ad rate managed per listing as a margin decision
Promoted Listings Standard takes a share of the sale, so the right rate depends on each item’s margin, age, and sell-through rather than on a blended account target. Ask whether the agency sets rates at listing or category level and what data drives it, because a single account-wide rate is a strong sign nobody is doing the work.
Inventory-aware campaign management
If a meaningful share of your inventory is used, refurbished, or single-quantity, promotion has to react as items sell out and new items list. Ask how the agency handles inventory that turns over constantly, and whether their process assumes a stable catalog of replenishable SKUs, because many do.
Seller performance treated as a marketing input
Feedback score, Top Rated status, defect rate, and shipping speed affect placement and conversion, so operational quality is not separable from advertising results. Ask whether the agency monitors seller standing at all, and what they would do if a performance metric slipped.
Listing quality before ad spend
Item specifics, category placement, condition descriptions, and photography determine whether promotion converts. Spending to drive traffic to weak listings amplifies a problem rather than solving it. Ask whether the engagement includes listing optimization or assumes your listings are already sound.

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.

How is eBay advertising different from Amazon advertising?

Structurally, in ways that matter. Promoted Listings Standard charges a percentage of the sale rather than per click, which turns rate-setting into a margin decision rather than a bid-management exercise. eBay also carries far more used, refurbished, and single-quantity inventory, so campaigns have to respond to a catalog that changes constantly. Agencies that apply an Amazon playbook directly tend to over-promote stale inventory and misread the economics.

Should we use Promoted Listings Standard or Advanced?

They solve different problems and many sellers use both. Standard is percentage-of-sale and effectively a visibility tax you accept on items you want moved, which makes it low-risk and simple. Advanced is cost-per-click with keyword control, which gives you more precision and more ways to waste money. The reasonable approach is Standard broadly across inventory you want to move and Advanced selectively where margin and volume justify active management.

Does seller feedback really affect ad performance?

Yes, indirectly but meaningfully. Feedback percentage, Top Rated Seller status, defect rate, and shipping performance influence both organic placement and buyer willingness to convert once they see your listing. That means a shipping or service problem shows up as an advertising problem, and no amount of rate adjustment fixes it. Any agency working this channel should be watching seller standing alongside campaign metrics.

Is eBay worth advertising on if we already sell on Amazon?

Often yes, particularly if you carry used, refurbished, open-box, or discontinued inventory that Amazon handles poorly. eBay also has less advertising competition in many categories. The honest caveat is that it usually will not match Amazon volume, so it works best as a genuine second channel with its own targets rather than as an afterthought managed with leftover attention.
