QQuartile

Quartile changes Amazon Sponsored Ads bids every hour, one keyword at a time, and moves budgets and placements in real time as results change. The same AI then reaches into Walmart, Instacart, Criteo retailers such as Target and Best Buy, and search and social ads on Google, Meta, Microsoft and ChatGPT. Every customer, small or large, also gets a dedicated strategist.

That makes Quartile a fit for brands that advertise across several retailers and want software plus a person accountable for results. Pricing is only available through a demo, and G2 reviewers cite cost as the main drawback even as they rate it 4.6 out of 5 across 215 reviews. We rate it 8.4/10 on our scale.

Quartile by the Numbers

Quartile’s product pages publish average results and certifications, and G2 provides review data.

The averages are Quartile’s own figures across partner brands, marked with a footnote on its site. They include the effect of strategists as well as software, so they describe the full service. A 41 percent ROAS gain is the headline; the 11 percent impression gain suggests most of that came from spending smarter on similar reach.

The awards list adds context. Quartile shows Amazon Ads Partner Awards and several G2 badges from 2025 and 2026, including Small Business Leader for Winter 2025, which suggests its review base includes many smaller brands and not only enterprise accounts.

ISO/IEC 27001 is the fact that separates Quartile from most Amazon ad tools in this category. Brands whose IT or procurement teams require a certified vendor will find that it shortens review.

How Quartile Runs Amazon and Retail Ads

Quartile combines an AI that changes bids and budgets with a strategist who sets direction. The AI side is most detailed for Amazon Sponsored Ads.

Campaign Structure

Quartile supports single-keyword, single-ASIN and single-match-type campaign structures, or it can work inside a brand’s existing structure. Single-keyword campaigns give the bidding engine clean data on each term, which is why its hourly changes are set at that level.

Hourly Bidding Toward a Goal

The AI decides keywords, bids and placements from historical data and Amazon Marketing Stream, then adjusts bids every hour to find the best bid per campaign. Budgets and placements update in real time. Goals are set in terms such as ROAS and TACOS, so a brand focused on profit and one focused on share can run different targets.

Custom Rules Next to the AI

Teams with their own playbook can write custom bid and budget rules and schedule them daily, weekly or monthly. Rules can run alongside the AI or replace it on chosen campaigns, which helps brands that must hold a fixed budget on a launch or protect brand terms.

Amazon Marketing Cloud Audiences

Quartile uses AMC to study shopper paths to purchase and build interest-based personas. Those audiences inform full-funnel plans across channels, so insights from Amazon can shape Google or Meta targeting. A Google to Amazon offer focuses on sending off-Amazon traffic to listings.

Promotions and Deal Planning

Promo Management is listed as its own solution. Deals such as Prime Day, Lightning Deals and coupons change conversion rates for days at a time, and a bidding engine that ignores them can overspend before a deal or underspend during it. Brands that run frequent promotions should ask how Promo Management feeds the hourly bidding.

Other Channels

On Google Ads, Quartile adjusts campaigns based on performance and segments them by results. Walmart, Instacart and Criteo retailers run through the same platform, and Promo Management covers deal planning. Quartile describes its AI in most detail for Amazon, so ask during the demo how deep automation goes on each other channel.

Reporting

Quartile offers expansive reports with granular performance data. Because bids move hourly, reports at keyword level matter: a brand can see which terms gained or lost spend each day and question the AI’s choices with its strategist. Teams that need to send numbers to finance should ask about export formats and how attribution windows are handled across channels.

The Strategist Relationship

Every customer gets a dedicated strategist backed by channel experts. Strategists meet clients regularly to review performance and advise on plans, and one testimonial mentions weekly data updates. Reviewers on G2 praise attentive account managers, while some mention turnover in that role.

A Quarter for a Beauty Brand

A beauty brand spending $30,000 a month on Amazon and $8,000 on Walmart signs on. In the first weeks, Quartile restructures top products into single-keyword campaigns and starts hourly bidding toward a ROAS goal. A custom rule holds a fixed budget on brand terms. By month two, AMC analysis shows that buyers of one serum often buy a cleanser within 30 days, and the strategist proposes an audience to target past serum buyers. Walmart campaigns adopt the same ROAS goal. The quarterly review compares ROAS, TACOS and new-to-brand orders.

What Stays With the Brand

Inventory is a shared concern. Hourly bidding can keep spending on a product that is about to stock out, so brands should tell the strategist about supply gaps early and ask whether a custom budget rule can cut spend on that product until stock returns. Quartile’s rules cover bids and budgets on daily, weekly or monthly schedules, so a planned stock gap can be handled in advance.

Budgets, goals, creative and product priorities stay with the brand. The strategist proposes; the brand approves. Listings and pricing sit outside Quartile’s scope.

Quartile Pricing by Demo

Quartile does not list prices on its product or small business pages. Prospects request a demo and receive pricing for their scope.

Building a Budget Without a List Price

Treat Quartile’s fee as part of total advertising cost. A brand spending $38,000 a month across Amazon and Walmart spends $456,000 a year on media. If hourly bidding lifts ROAS from 3.0 to 3.5 at the same spend, attributed sales rise from $114,000 to $133,000 a month, a gain of $19,000 in monthly sales. The quote should be judged against the margin on that gain.

Published self-serve rates give a reference point. Teikametrics Essentials costs $149 a month on annual billing for up to $10,000 in monthly ad spend, with 3 percent of spend above $10,000 on its Advanced tier, so the same $38,000 would carry about $840 a month in spend-based fees on Teikametrics plus its base price. Helium 10’s Ads product carries a 2 percent fee on spend on the Diamond plan.

Questions for the Demo

A demo goes further with a short list. Ask how the fee is calculated and whether it changes with spend. Ask which channels get hourly automation and which are managed by rules or by the strategist. Ask for the minimum contract length and notice period. Ask how many accounts each strategist manages and how handovers work when one leaves. Ask which reports can be exported and how often data refreshes. Each answer either confirms a fit or flags a cost the brand would otherwise find later.

Ask Quartile whether its fee is flat, tiered or tied to ad spend, and how it changes as channels are added.

Quartile Compared With Perpetua, Teikametrics and Eva

A brand choosing among these should start from where its ad money goes. If 90 percent of spend is Amazon Sponsored Ads, Perpetua or Teikametrics may cover it at lower effort. If a third of spend sits on Walmart, Instacart and Google, Quartile’s reach becomes the deciding factor, since one strategist and one report cover every channel.

Quartile reaches the most ad channels of the four and is the only one here showing an ISO/IEC 27001 certification on its product page. Teikametrics is the self-serve choice with a public price. Perpetua centers on Amazon goals, and Eva adds repricing and reimbursements. All four can sit beside Amazon’s free Seller Assistant.

Brands That Fit Quartile

Brands advertising on Amazon plus Walmart, Instacart or Criteo retailers fit best, since one platform and one strategist cover them all.

Brands that want to test new ad formats early may also like the channel list. ChatGPT Ads appears beside Google, Meta and Microsoft, so a brand curious about AI search advertising can try it with the same strategist.

Companies with security reviews in procurement benefit from the ISO/IEC 27001 certification.

Brands moving budget from Google to Amazon, or running both, fit the Google to Amazon program and the shared AMC audiences that inform targeting on both sides.

Retail media teams at consumer goods companies also fit. Criteo coverage reaches Target, Best Buy and other retailers that many brands buy through separate tools today.

Teams that want a person to meet with each month, while still getting hourly automated bidding, match Quartile’s model.

Advertisers Who May Prefer a Self-Serve Tool

Small sellers with modest ad budgets who want a known monthly price may prefer Teikametrics Essentials or Helium 10, both with public pricing.

Resellers who need a Buy Box repricer will not find one here. Quartile manages ads, so tools such as Aura or Seller Snap cover that job.

Brands that want full control without a strategist may find the service layer more than they need. Custom rules exist, but the model is built around shared management.

Cost, Handovers and Channel Depth

Cost is the most cited drawback on G2, so get the quote in writing with how it scales. Ask what happens to the fee when ad spend rises or a new channel is added.

Some G2 reviewers mention account manager turnover. Ask how handovers work and whether notes and strategy documents transfer with the account.

Quartile describes automation in the most detail for Amazon. Confirm what runs automatically on Walmart, Instacart and Google before relying on hourly changes there. Quartile could publish starting prices for its small business offer.

Our Take on Quartile for Multi-Retailer Brands

Quartile earns 8.4/10 on our scale. It scores well on autonomy with hourly bidding, on integrations with nine ad channels, on trust with ISO/IEC 27001, and on sentiment with 4.6 out of 5 from 215 G2 reviews. Pricing value is the lowest score because prices are only available after a demo.

The path to a higher score is mostly about transparency. A published starting price for the small business offer, and a clear description of which actions run automatically on each non-Amazon channel, would answer the two questions buyers raise most often.

For brands spending meaningfully across several retailers, Quartile is a sensible demo to book. Bring your current ROAS and TACOS by channel and ask the team to model the fee against an expected improvement.

Brand Questions About Quartile

How Much Does Quartile Cost?

Quartile does not publish prices. Prospects request a demo, and pricing is set for the brand’s scope. Bring monthly ad spend by channel to the demo, since the number of channels and the spend level shape the quote.

How Often Does Quartile Change Bids?

Quartile says it adjusts bids hourly for each single-keyword campaign on Amazon Sponsored Ads, and updates budgets and placements in real time.

Which Ad Channels Does Quartile Support?

Amazon Sponsored Ads, Amazon DSP, Walmart, Instacart and Criteo retailers on the marketplace side, plus Google Ads, Meta Ads, Microsoft Ads and ChatGPT Ads. Criteo extends reach to retailers such as Target and Best Buy.

Is Quartile Software or a Managed Service?

Both. The AI handles bids, budgets and placements, and every customer gets a dedicated strategist backed by channel experts. Strategists meet clients on a regular schedule to review results, and brands can still add their own rules for bids and budgets.

Is Quartile Secure Enough for Enterprise Procurement?

Quartile states it is ISO/IEC 27001 certified and publishes an information security statement, which covers a common enterprise requirement. Procurement teams should still request the certificate scope and any data processing terms, since ad tools hold account access across several retailers.
