U.S. ecommerce sales grew 12.2% year over year in Q2 2026, nearly twice the pace of total retail sales. That leaves plenty of opportunity for brands, but capturing it takes more than strong performance in a single channel. Acquisition, conversion, and retention all have to work as one system.
Finding an agency that can genuinely cover that full journey takes some digging. So we did the legwork for you and reviewed the leading ecommerce marketing agencies on the market. We compared their capabilities across the funnel and narrowed the field to ten standouts for 2026.
Jump to the quick picks for the shortlist, or keep reading to see what earned each agency a place.
Match the agency to the constraint that costs you the most revenue today.
| Your bottleneck | What to look for | Start with |
|---|---|---|
| Paid acquisition has plateaued | Incrementality testing and a steady creative-testing cadence | Tinuiti, Wpromote, Common Thread Collective |
| Organic and AI search are weak | SEO plus AI search work with ecommerce proof | Coalition Technologies, Power Digital, SeedX |
| Traffic arrives but converts poorly | CRO and store work bundled with media | P3 Media, Disruptive Advertising |
| Repeat purchase rate is low | Email, SMS, and loyalty under the same team as media | Hawke Media, Disruptive Advertising, Power Digital |
| Marketplaces drive a growing share of sales | Amazon and Walmart management tied to paid media | Tinuiti, Hawke Media, Wpromote |
| Creative volume is the choke point | UGC and creator production wired into media testing | Fieldtrip, Power Digital |

An agency made the list when it shows at least four of the seven layers described below for ecommerce clients, runs an active practice, and backs it with named clients or case studies. Agencies that cover one or two layers, such as CRO-only shops, are outside a full-funnel list.
We counted layers from each agency's public service pages and case work, checked on October 2, 2026. Named clients and case-study results count as proof, and results an agency reports about itself are labeled as such. Clutch review counts run from 2 to more than 160 across these agencies, so ratings played no part in the order.
Fieldtrip is our agency, and we list it first. It runs all seven layers, and the other nine follow by number of confirmed layers, then depth of public proof.
A full-funnel ecommerce digital marketing agency covers seven layers, from the first ad to the second order. Integrated full-service agencies keep clients longer: the 2025 ANA and 4As study, as reported by Shopify, found an average relationship of 7.3 years for integrated agencies against 3.7 years for media-only agencies.
Use the layers below as a checklist when you brief any agency. Each one maps to a column in the comparison matrix later in this article.
Ten agencies cleared the bar. The matrix shows which layers each one runs, based on what it shows publicly. A cross means we found no public evidence of that layer.
| Agency | Paid media | SEO and AI search | CRO and site | Email and SMS | Marketplaces | Creative | Measurement | Layers |
|---|---|---|---|---|---|---|---|---|
| Fieldtrip | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | 7 |
| Tinuiti | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | 7 |
| Wpromote | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ | 7 |
| Power Digital | ✓ | ✓ | ✓ | ✓ | ✗ | ✓ | ✓ | 6 |

At Fieldtrip, we bring strategy, creative, media, and measurement into one system. Our small, autonomous teams work from a shared strategy, while specialist agencies across the group extend that capability where needed: inBeat for creators, 9AM for paid and programmatic media, Creative Milkshake for UGC and paid social creative, and Bluethings for SEO and GEO. Brands can start with one team and bring in additional expertise as their needs expand.
That model is built for work that crosses channels rather than sitting neatly inside one discipline. For Genomelink, we developed a UGC system that reduced CAC by 73% and increased registration completion by 124%. For Native, we scaled creative production across four campaigns, delivering more than 750 UGC assets to support ongoing testing and paid media performance.
Tinuiti runs all seven layers and measures each with holdout tests. For DSW, Tinuiti ran a Meta test with a 30% holdout group that tied online and in-store sales to paid social. The case study reports 23% more omni purchases and a 29% lower incremental CPA.
Amazon work runs through an Amazon Ads Advanced Partner practice, so marketplace spend sits next to paid social in one plan. Shopify and Klaviyo specialization is not part of the public pitch, so brands built on that stack should ask for examples.
Wpromote also covers all seven layers. It merged with creative agency Giant Spoon in late 2025, which put a Cannes Lions-winning creative team under the same roof as its performance media.
Its KidKraft case study shows the model at small scale: sixteen influencers and paid social on Instagram and TikTok sold out the Beat Board launch, with 80,000 units sold and 4.6 million unique reach, per Wpromote. Clutch lists a $250,000 minimum and a 90% enterprise client base, so the fit leans toward large budgets.
Creative Affinity is why Power Digital made the shortlist: it links customer lifetime value to individual ads on Meta and TikTok, so each ad is judged on the profit it brings in. Like Tinuiti, Power Digital runs incrementality testing and media mix modeling, and it adds a revenue forecasting tool it reports as 90% accurate.
Each account gets an Executive Sponsor who acts as the team CMO and keeps every channel pointed at one view of the funnel. The published case studies are anonymized, so ask for named references before you sign.
Disruptive Advertising starts with a free game plan that diagnoses COGS, LTV, and AOV alongside ROAS, then offers a done-for-you tier with a 90-day refund guarantee. That gives a buyer a lower-risk way in.
Nani Swimwear is its lead case, with 510% revenue growth and a 75.97% drop in cost per add to cart, per Disruptive. Pricing is not published, and many of its best-known client names come from B2B and lead generation, so ask for ecommerce references.
Hawke Media is the generalist of the group, running paid, SEO, lifecycle, and marketplaces under one roof. It built its Amazon practice by acquisition: it bought Amazon specialist ARMR in May 2024, one of the 16 acquisitions it lists since 2018.
Its K-Swiss case study reports 900% ROAS on a one-day sale for a Ghostbusters collection. Hawke shows no CRO depth, and Clutch lists only two reviews, so references matter more here.
Coalition Technologies leads with search. This family-owned Los Angeles agency, founded in 2009, sells AI SEO as its own offer and builds Shopify Plus stores to match.
Its CMC Motorsports case study credits SEO, PPC, email, and SMS alongside a new Shopify Plus site for 849% organic revenue growth over two years. Creative production and measurement are the two layers missing from its itemized services.
P3 Media is a Shopify Platinum Partner, a tier held by fewer than 1% of agencies globally, and that Shopify depth shapes everything it sells. When Bartesian wanted to sell in Canada, P3 opened an international storefront that grew the brand's revenue 16x, per a Shopify partner profile.
P3 reports a 51% average ROAS increase after six months across its clients. Email, marketplace, and measurement services do not show up in its public materials, so ask how those layers get covered.
Common Thread Collective assigns each client a Prophit Engineer, a strategist who builds the forecast, manages ad spend, and sets the creative playbook for paid. The Normal Brand calls its Prophit Engineer the conductor of its business, and the agency reports an average client tenure of 14 months or more.
Think of it as paid media plus retention, creative, and measurement. SEO, CRO, and Amazon work do not appear in its public materials.
SeedX extends forecasting to store data and inventory and ties every decision to contribution margin. That revenue-operations approach suits brands whose margins leak between marketing, forecasting, and stock.
Its ecommerce page reports 86% higher online sales for New Yorker Bagels, 76% more orders for Solstice Medicine, and a 1.5x higher AOV for Bees & Trees, all undated. Ecommerce is about a quarter of its work on Clutch, and it shows no marketplace or creative offer.
Ecommerce marketing agencies price as a retainer, a project fee, a performance fee, or a hybrid, and published figures vary widely. Shopify's guide cites a Databox survey of more than 40 agencies in which most clients paid less than $30,000 per year. The sample is narrow, so read it as a rough direction only.
| Pricing model | How it works | Best fit |
|---|---|---|
| Retainer | Fixed monthly fee for a defined scope of channels | Ongoing media, SEO, and lifecycle work |
| Project | One fee for bounded work, such as a store build or migration | Replatforms and new checkout flows |
| Performance | Fees tied to a share of revenue, a CPA threshold, or incremental lift | Brands with clean attribution and stable margins |
| Hybrid | Base retainer plus a performance bonus, or a project fee plus maintenance | Teams that want shared upside |
Project minimums give a sense of the range. These are the minimums each agency lists on its Clutch profile, so they show where an engagement starts:
| Agency | Minimum project size on Clutch |
|---|---|
| Coalition Technologies | $1,000+ |
| Common Thread Collective | $5,000+ |
| Hawke Media | $5,000+ |
| Power Digital | $5,000+ |
| SeedX | $5,000+ |
| Wpromote | $250,000+ |
Cost scales with the number of layers an agency runs for you. Ask for itemized quotes from at least two or three agencies, as Shopify recommends, with each funnel layer priced separately.
Choose the agency whose layers match your biggest leak, then test the fit with a scoped first quarter.
For a formal pitch process with scoring and timelines, our marketing RFP guide covers each step. Put these questions to every shortlisted agency:
Shopify's guide lists several red flags worth keeping on hand:
Pick the agency whose layers cover your biggest leak, and tie the first 90 days to revenue targets. If you want creative, media, search, and lifecycle running from one strategy, that is the work we do at Fieldtrip. Tell us where your funnel loses the most revenue, and we will tell you plainly whether we are the right fit or whether one of the agencies above suits you better.
Plan on 90 days for a first read and about six months for compounding gains. Shopify advises writing goals into the contract with checkpoints at 30, 60, and 90 days. SEO usually takes longer than paid media, so ask each agency for a timeline per layer.
One agency fits when channels need to share data and creative, because a single team can move budget between them. Specialists fit a single deep problem, such as store CRO. Many brands combine both: an in-house generalist manages the agency relationship while the agency runs channel execution.
Ask for revenue attribution, conversion rate trends, and channels that underdelivered. Disruptive Advertising also diagnoses COGS, LTV, and AOV, and Tinuiti reports incremental lift from holdout tests. Reporting that connects activity to revenue lets you judge each layer on its own.
Bring it in-house when the work is steady, high in volume, and gains from deep knowledge of your brand. An agency fits when you need specialized expertise quickly or when the workload does not justify a full-time hire.
