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.

Back-to-School Signals Are Already Telling Us How Q4 Will Go

Back-to-school spending hit a record $146.8 billion this year, according to the National Retail Federation, and 62% of shoppers had already made their purchases by early July. That one number explains a lot of what we're seeing on Amazon in mid-August. Demand didn't shrink, it just moved earlier, and Amazon's shift of Prime Day into June pulled a real chunk of back-to-school spend into Q2 instead of Q3.

If you built your August plan around a late-summer surge, you showed up to a party that started six weeks before you got there.

Price isn't deciding these purchases the way it used to, either. Only 16% of shoppers say price alone drives where they buy, so the other 84% are looking for proof: durability, reviews, a detail page that answers their question before they have to ask it. At the same time, ads got more expensive, with cost per click up roughly 8 to 12% year over year. Every click into your listing costs more than it did last August, and the shoppers clicking are more skeptical once they land. Sending expensive traffic to a listing that can't close the sale is the fastest way to burn through a Q4 budget before the season even starts.

Reviews take weeks to build and content takes time to test, and neither happens overnight. But both compound, and every improvement made in August makes every ad dollar work harder once Prime Big Deal Days hits and holiday traffic surges on top of it. The brands pairing ad spend with equal investment in reviews and detail pages, while there's still runway before Q4, are the ones putting that expensive traffic to work instead of just paying for it.

Back-to-school is a dress rehearsal for Q4, and the next 60 days decide how the real season goes. A few things worth doing now, based on what August already showed us:

Submit your Prime Big Deal Days and Black Friday deals before those windows close, since a late submission gets you nothing once the deadline passes. Lock in your Q4 inventory buys too, because FBA stock for Black Friday and Cyber Monday needs to arrive by mid-October, and earlier than that if you're using AWD. Take a hard look at your top ASINs for the same leaks back-to-school just exposed, whether that's thin reviews, weak imagery, or a detail page that isn't answering the buyer's real question. Start building your retargeting audiences now as well, since the shoppers clicking during Prime Big Deal Days become your warm list heading into Black Friday. And set your Q4 pricing strategy while you can still plan for margin, instead of reacting to it once the season's already underway.

The signals are already in front of us. Fixing what they point to now, before Turkey 5 hits, is a lot cheaper than fixing it during peak week.

If you want a second set of eyes on where your listings and ad strategy stand heading into Q4, we're glad to walk through it with you.
