Services

A relationship that works for you.

Most brands start with full-service management. Some come to us for advertising alone. All run on the same operating standard and the same senior team.

Full-Service Management

We act as your dedicated ecommerce team, from strategy to daily execution, so you can step back and build the brand. The engagement covers our Foundational Assessment, Blueprint, Build, and Inspect process, with the AIQ Scorecard built in. Management across Amazon, Walmart, Home Depot, Whole Foods, Lowe's, Costco, Wayfair or wherever your distribution calls for.

Advertising Management

Professional Amazon ad management on its own, for brands with an in-house team that needs dedicated ad expertise, or brands not yet ready for full service. We run Sponsored Products, Brands, and Display, with DSP available, all managed to TACoS rather than ACoS alone, with monthly reporting that ties spend to results. When listings limit ad performance, we tell you.

Launchpad

We help brands who are new to Amazon get prepared, trained & launched on a project basis with the opportunity to continue in an on-going capacity.

Customized Project Work

Need training to get your team up to speed on a new Amazon process? Or your business to be AI measured & optimized? Preparing for a retailer Top to Top or JBP and need a hand? Or surge resources while someone on your team is out? We have done it all — let us know what you are thinking and we would be happy to create a custom scope.

Not sure which fits?

The Foundational Assessment answers that. We look at your channel first, then recommend the engagement that earns its keep.

About Keystone

Not our first rodeo. Just our best one.

We started Keystone in 2022, after taking a previous ecommerce agency public in late 2020. We had run a 250-person digital commerce team and around $2 billion in retail sales. We were ready to get back to what mattered — working with people & brands we care about, hands-on strategy & real results.

We're a boutique agency with enterprise-grade range. We work with brands of every size, from emerging challengers to publicly traded companies, and we operate as an extension of your team rather than an outside vendor.

Our approach

A proven process, tailored to your unique needs.

No mystery, no black box. You see the plan, you see the work, and you see a senior operator behind both. AI is part of how we do it, used where it sharpens the work rather than as a headline.

01 / FOUNDATIONAL ASSESSMENT

Read the channel

A structured diagnostic of your current position, the competitive landscape, and the opportunity gaps. It's the required first step, and it's where the plan starts.

02 / BLUEPRINT

Set the plan

A living roadmap built from the assessment. It aligns goals, KPIs, and the principles of how we work together, and it changes as the channel does.

03 / BUILD

Run the work

Daily execution across data, media, merchandising, content, catalog, and operations, guided by the Blueprint and owned by your team.

04 / INSPECT

Keep it honest

An ongoing evaluation loop. AI-assisted analysis and senior human review track performance, watch the competition, and refine the plan as the market shifts.

The AIQ Scorecard. A benchmark of your brand's readiness for AI-driven retail across channels. It tells you where the highest-value investment is, so the spend follows the opportunity.

See it on your own account.

A Foundational Assessment is the fastest way to know what's possible. We'll show you the gaps and the plan before you commit to anything.

How to Win the AI Recommendation on Amazon

Published August 7, 2026

Amazon changed how people buy this year in a way a lot of brands haven't caught up to yet. Alexa for Shopping launched in May as a default AI layer over the whole shopping experience, and it applies to every signed-in customer with no Prime membership and no Echo device required. It shows shoppers a full year of price history before they check out, lets them set alerts in natural language like "deals on protein bars with no artificial sweeteners" rather than picking a category, and it can buy on a shopper's behalf when a product hits their target price, with no final review screen along the way.

The auto-buy piece matters most here, because when an AI completes the purchase at a price the shopper set in advance, there's no second chance inside the cart to win them over with a better image or a coupon on the way out, and the decision has been made before you would normally have a shot at it. That shifts the job from getting found and persuading someone toward being the product the AI already trusts.

A few things decide that. Shoppers are describing what they want in plain speech now, saying things like "no artificial sweeteners" or "under $30" or "good for sensitive skin," so your listing needs to state those same attributes in the same plain terms the AI is matching against. Alexa is also showing a full year of your pricing, which means erratic swings and a price that never moves both work against you, and a clean, believable price history has quietly become part of your conversion story. Because the AI is checking whether you fit the request rather than reading your brand story, complete attributes, accurate specs, and reviews that speak to real use cases are what put you inside the recommendation instead of beside it.

A lot of brands are still optimizing for the shopper who scrolls, compares, and clicks, and that shopper hasn't gone anywhere, but a growing share of purchases are being decided by an AI acting on someone's behalf at a price set ahead of time, with no person at the finish. Showing up well in that moment is a different discipline, and it's one we're already running for the brands we manage.
