Sellozo Review

Sellozo, a marketplace ad tool for Amazon sellers, automates sponsored-ad bidding by hour and cuts wasted search terms with its own rule-based controls. Its price stays flat rather than rising with ad spend, and there is no minimum term.

Research-based review. Features and prices are checked on the vendor's own website, and the score is worked out from those facts. We haven't tested it hands-on yet.

The verdict

Sellozo suits Amazon sellers wanting flat, predictable pricing for sponsored ads, but it skips DSP campaigns and ad creative entirely, unlike BidX's broader coverage.

Pros

  • Sellozo automatically adjusts bids to a target ACoS across connected Amazon marketplaces.
  • Negative keyword creation is fully automated to cut wasteful spend.
  • Dayparting has its own dedicated feature that automates ad scheduling by budget and ACoS goals.
  • Billing is month-to-month with no contract and no setup fee.

Cons

  • There is no free plan.
  • Sellozo does not run Amazon DSP display and video ads.
  • Sellozo itself offers no done-for-you managed service; it only runs a free referral to an independent agency.

Why these numbers

Ad networks it manages: Counted from marketplaces_supported. Amazon only (across 20 country storefronts); Walmart, Google, Meta, TikTok, Microsoft, Instacart and eBay never mentioned on the homepage, software or services pages.

Excludes wasted search terms by itself: Also listed as 'Negative Keyword Management' in the pricing page's plan feature list.

Bids by hour or day: Sellozo has a whole product page dedicated to this feature.

Your own automation rules: Custom control of campaign linkages and transfer rules (Campaign Studio).

Amazon DSP beyond sponsored ads: 'DSP' never appears on the homepage, software pages or services pages checked; product is Sponsored Ads / search-focused only.

Makes the ad creative: Checked AI Optimization, Campaign Studio references and homepage for ad copy, image or video generation; the product's AI is used for bidding and keyword discovery only.

A done-for-you tier: "Strategic Management" is a free referral service that matches sellers with an independent third-party agency; Sellozo itself does not run ads for customers.

Minimum termnone1 / 1
Why these numbers

Cheapest paid plan, monthly: Cheapest paid plan on the monthly term. Single self-serve plan; price scales only with the number of connected Amazon marketplaces (1 to 20 via a slider on the pricing page), not with ad spend. "Volume discounts available for large agencies" is mentioned with no figures.

Free trial: Repeated on every page checked.

What the price grows with: The pricing page explicitly contrasts itself with the category's usual ad-spend-percentage pricing. It does step up per additional connected marketplace, but never with ad spend, revenue, orders, sessions or impressions, so 'flat' is the closest fit.

Setup fee on top: Checked the pricing page and the Terms of Use 'Fees and Payments' section; no setup, onboarding or implementation charge mentioned anywhere, and the product has no enterprise/quoted tier to hide one in.

Minimum term: The Terms of Use 'Term' section adds a caveat: "Certain subscription plans may only be terminated by you after a certain length of time (see Pricing page for details)", but the only plan shown on the Pricing page (Sellozo Platform) is explicitly month-to-month with no contract, so that caveat does not appear to apply to any currently published plan.

How the Spec Score works

Scored from what Sellozo publishes on its own site. Not a hands-on test.

Compared with 5 marketplace ad tools. Facts checked 24 Sep 2026.

A fact the vendor does not publish gets half the points, or the typical value for a number, and says so. It never counts as a no. How we score.

Sellozo automates Amazon advertising with a single flat-rate plan that prices by the number of connected marketplaces rather than a share of ad spend. What decides whether it suits you is that flat structure: it fits a seller who wants a predictable bill, and it is built for Amazon ads.

What is Sellozo?

Sellozo is based in the United States and was founded in 2017. It runs against Amazon Seller Central across 20 country marketplaces, and has no Shopify App Store listing.

What Sellozo runs for you

Sellozo sets a target ACoS and automatically adjusts bids to reach it, and it automates negative keyword creation to cut wasteful spend. Dayparting has its own dedicated feature, automating ad scheduling based on budgets and ACoS goals. Campaign Studio is a drag-and-drop interface for designing a keyword-harvesting campaign strategy and building new campaigns, not only managing existing ones, and it also gives custom control over campaign linkage rules.

Sellozo does not run Amazon DSP display and video ads, and its AI is used for bidding and keyword discovery rather than generating ad creative. Sellozo itself does not offer a done-for-you managed service; instead it runs a free service that matches sellers with an independent third-party agency that uses the Sellozo platform.

Sellozo pricing: what each plan gives

Sellozo pricing screenshot
Sellozo, Pricing

The Sellozo Platform plan costs $250 a month for the first connected marketplace, plus $50 a month for each additional marketplace, up to 20 marketplaces. There is no free plan, but there is a 30-day free trial. There is no setup fee, and billing is month-to-month with no contract.

Privacy and security

Support runs through email.

Who Sellozo suits

Sellozo suits an Amazon seller who wants automated bid management, dayparting and negative keyword automation at a predictable flat price, with no contract and no setup fee.

It suits less well a seller who advertises on Amazon DSP, since Sellozo has no DSP support.
