Best Paid Media Agencies for eCommerce Stores [2026]

Let's get the uncomfortable truth out of the way: most eCommerce brands are burning 30-40% of their ad spend on campaigns that will never be profitable. Not because paid media doesn't work — it works extremely well when done right. But because the agency managing their ads is optimizing for clicks and impressions instead of profit.

Here's the thing about eCommerce paid media in 2026. The platforms have changed. Meta's algorithm is smarter than it was two years ago — but that means the old playbook of micro-targeting 47 different audiences doesn't work anymore. Google's Performance Max has consolidated Shopping, Display, and Search into a black box that rewards creative quality over keyword lists. And TikTok Shop has created an entirely new purchase path that most agencies haven't figured out yet.

The agencies on this list have adapted. They understand that profitable eCommerce paid media in 2026 is about creative volume, first-party data, proper attribution (not last-click), and coordinating paid acquisition with email/SMS retention so the math actually works on a customer-lifetime-value basis.

If You're in a Hurry

Our top pick: GOSH Digital. We manage paid media as part of a full eCommerce growth system — your Meta and Google ads are connected to your Klaviyo flows, your landing pages, and your post-purchase experience. 150+ eCommerce clients, $23M+ in tracked revenue across all channels. Book a free audit.

How We Evaluated These Agencies

• ROAS with context — A 4x ROAS on a product with 70% margins is great. A 4x ROAS on a product with 30% margins is breakeven. We looked for agencies that think in terms of contribution margin, not just ROAS.
• Platform breadth — Meta, Google, TikTok. In 2026, most eCommerce brands need at least two of these three. Agencies locked into a single platform leave money on the table.
• Creative capabilities — The #1 lever in paid media right now is creative. Agencies that can produce 30-50+ ad creatives per month — UGC, static, video — outperform agencies that produce 5.
• Attribution sophistication — Last-click attribution is dead for multi-channel eCommerce. We prioritized agencies using triple-whale, Northbeam, or similar post-purchase attribution tools.
• eCommerce focus — Paid media for eCommerce is fundamentally different from paid media for lead gen, B2B, or app installs. We only included agencies with deep eCommerce DNA.

The 7 Best Paid Media Agencies for eCommerce

1. GOSH Digital — Best for Paid Media + Retention Integration

Best for: eCommerce brands doing $500K-$50M who want paid media connected to email/SMS so customer acquisition costs actually pay back

Pricing: $2,500-$8,000/month management fee (separate from ad spend); typical client ad spend is $10K-$200K/month

Key strength: We don't run paid media in a silo. Your Meta ads, Google campaigns, Klaviyo flows, and Shopify store are managed as one system — so every dollar spent on acquisition has a retention strategy behind it.

Most paid media agencies will optimize your ROAS and send you a report. That's fine, as far as it goes. But it doesn't go far enough for eCommerce.

Here's the problem we solve: A brand spends $50K/month on Meta ads. The agency reports a 3.5x ROAS. Looks good on paper. But when you dig into the numbers, 40% of those "conversions" are existing customers who would have purchased anyway. And 60% of the new customers never buy a second time because there's no post-purchase email sequence, no winback flow, and no cross-sell strategy. The true new-customer ROAS is closer to 1.8x — which might be underwater depending on margins.

At GOSH Digital, we solve this by managing paid media and retention together. When we acquire a new customer through Meta or Google, that customer immediately enters a Klaviyo flow designed to drive a second purchase. We build custom audiences from our email segments, suppress existing customers from prospecting campaigns, and feed purchase data back into platform algorithms to improve targeting. The result is a paid media strategy that compounds over time instead of plateauing.

On the platform side, we run Meta (Facebook and Instagram), Google (Shopping, Search, and Performance Max), and TikTok ads. We produce 30-50+ ad creatives per month for most clients — a mix of UGC, product photography, lifestyle imagery, and video — because creative volume and variety is the single biggest ROAS lever in 2026. We test constantly: hooks, angles, formats, placements. And we track everything through post-purchase attribution (we recommend Triple Whale or Northbeam) because last-click attribution lies.

2. Common Thread Collective (CTC) — Best for Large-Scale DTC Growth Systems

Best for: DTC brands doing $10M-$100M+ that want a system-driven approach to scaling paid media

Pricing: $10,000-$30,000+/month (usually bundled with creative and strategy)

Key strength: Their "Growth Map" methodology — a predictive model that forecasts revenue based on ad spend, AOV, conversion rate, and repeat purchase rate.

CTC is probably the most talked-about eCommerce growth agency right now, and for good reason. Their approach is genuinely systematic. They build a financial model (the "Growth Map") for every client that ties ad spend to revenue outcomes with real math — not vibes. If you increase spend by $20K, the model predicts what happens to revenue, profit, and cash flow. Then they test against it.

Their creative team is also strong. They produce high volumes of UGC and branded content that feeds their media buying. And their reporting is some of the best in the industry — clear, tied to financial outcomes, and honest about what's working and what's not.

The downside is cost and scale. CTC isn't built for brands doing $1M-$3M. Their minimums are high, their processes assume a certain level of brand maturity, and you'll be competing for attention with much larger clients. If you're past $10M and ready to invest seriously in scaling, they're excellent. Below that, you're probably paying for more infrastructure than you need.

3. Lunar (formerly MuteSix) — Best for Creative-Led Performance

Best for: DTC brands that need high-volume creative production paired with media buying

Pricing: $5,000-$15,000/month

Key strength: Creative production at scale. They have an in-house studio that produces UGC, video ads, and static creatives — and they test them aggressively.

Lunar (the agency formerly known as MuteSix) went through an identity crisis after the Dentsu acquisition, but the core team is still solid. Their biggest strength is creative production. They understand — better than most agencies — that creative is the #1 variable in paid media performance right now. More creatives means more tests. More tests means faster learning. Faster learning means lower CPAs.

They produce a high volume of ads, test them systematically, and scale the winners. Their media buying is competent across Meta and Google, though TikTok is more hit-or-miss. The weakness is that they're more of a paid media + creative shop than a full-funnel agency. They won't manage your email, fix your Shopify store, or build your SEO strategy. You're getting ads and creative — which is great if that's what you need, but limiting if you want one team handling everything.

4. Structured Social — Best for Meta Ads Specifically

Best for: eCommerce brands spending $20K-$200K/month on Meta ads that want a specialist, not a generalist

Pricing: $3,000-$8,000/month

Key strength: Deep Meta (Facebook/Instagram) expertise. They live inside Ads Manager and understand Meta's algorithm better than most.

Structured Social is a Meta ads specialist, and they're very good at it. While most agencies spread their attention across 3-4 platforms, Structured focuses almost entirely on Meta. That means they see patterns and algorithm shifts faster, they test more aggressively, and they have a deeper understanding of what's working on Facebook and Instagram right now.

Their approach is data-heavy. They use real attribution data (not just what Ads Manager reports) to understand true performance, and they structure campaigns to work with Meta's algorithm rather than fighting it. In 2026, that means broad targeting, high creative volume, and letting the algorithm find the buyers — which is the opposite of what most brands learned in 2020.

The obvious limitation is that they're Meta-only. If you need Google Shopping, TikTok, or Pinterest, you'll need another agency or team for those channels. And they don't touch email or CRO. But if Meta is your primary acquisition channel and you want someone who's obsessed with it, Structured is a strong pick.

5. Pilothouse — Best for Multi-Platform Creative Testing

Best for: eCom brands doing $3M-$30M that want aggressive creative testing across multiple platforms

Pricing: $4,000-$12,000/month

Key strength: They run creative testing at scale across Meta, Google, TikTok, and Pinterest — and they're fast at iterating.

Pilothouse has built a reputation for speed and creative output. Their model is built around producing a high volume of ad creatives, testing them quickly across multiple platforms, and scaling what works. They're particularly strong on TikTok — they understood the platform early and have real case studies showing TikTok driving profitable conversions for eCommerce brands.

They also do solid work on Meta and Google. Their reporting is good, their team is responsive, and they move fast. The downside is that they're a paid media and creative agency, not a full-funnel partner. Similar to Lunar, you won't get email, SMS, or CRO from them. And their strategic depth can vary by account team — some teams are more data-driven than others.

6. KlientBoost — Best for Brands That Need Google Ads Expertise

Best for: eCommerce brands spending heavily on Google Ads (Shopping, Search, Performance Max) that need a specialist

Pricing: $3,000-$10,000/month

Key strength: Google Ads expertise, particularly Shopping campaigns and Performance Max optimization for eCommerce.

KlientBoost started as a PPC agency and Google Ads is still their strongest channel. They understand how to structure Shopping campaigns for large catalogs, how to optimize Performance Max when it's treating your budget like a black box, and how to use Search campaigns to capture high-intent buyers for expensive product categories.

They've expanded into Meta and other platforms, but Google is where they shine brightest. If your brand sells products that people actively search for (vs. impulse buys), Google is probably your highest-intent channel, and KlientBoost knows how to maximize it. They also do landing page design and CRO, which is a nice bonus — the combination of good Google ads and optimized landing pages can dramatically improve conversion rates.

The limitation is that they're not eCommerce-native in the way some other agencies on this list are. They also work with B2B, SaaS, and service businesses, so the eCommerce-specific knowledge isn't as deep. And their email/SMS capabilities are minimal.

7. Hawke Media — Best for Flexible, A La Carte Paid Media Services

Best for: Brands that want to hire paid media management without a long-term contract or big commitment

Pricing: Starts around $3,000/month; month-to-month contracts available

Key strength: Flexibility. Month-to-month contracts, a la carte services, and the ability to scale up or down without penalty.

Hawke Media's biggest selling point is flexibility. Most agencies want 3-6 month minimums. Hawke offers month-to-month contracts, which means you can test them with lower risk. They offer paid media across Meta, Google, TikTok, and Amazon, and you can add or remove channels as needed.

The quality is solid — not top-tier, but consistently good. They have a large team with specialists in each platform, and their processes are well-documented. The tradeoff for flexibility is depth. Because they're structured for easy in-and-out, the team may not invest as deeply in understanding your brand as an agency that knows you'll be there for a year. And their creative capabilities are more basic — you might need to bring your own creatives or hire a separate creative team.

For brands that need paid media management now and aren't ready for a major commitment, Hawke is a smart low-risk starting point.

How to Choose the Right Paid Media Agency

The Math You Need to Do First

Before you talk to any agency, you need three numbers:

1. Your target CPA (cost per acquisition) — Based on your average order value, gross margin, and how many times a customer needs to repurchase for the initial acquisition to be profitable.
2. Your monthly ad budget — Be realistic. If you can only afford $5K/month in ad spend, most agencies on this list aren't going to move the needle. Paid media generally needs at least $10K-$15K/month in ad spend to generate meaningful data and results.
3. Your LTV:CAC ratio — If you don't know your customer lifetime value, you can't evaluate whether your ad spend is working. An agency that costs more but drives customers with a higher LTV is worth more than a cheap agency that drives one-time buyers.

Questions to Ask Every Paid Media Agency

"How do you handle attribution?" — If they say "we use the numbers in Ads Manager" without mentioning a third-party attribution tool (Triple Whale, Northbeam, Rockerbox), they're working with bad data. Meta and Google both over-report conversions. A good agency knows this and accounts for it.

"How many creatives do you produce per month?" — In 2026, creative volume is the #1 lever. Agencies producing fewer than 15-20 creatives per month are leaving performance on the table. The best agencies produce 30-50+.

"What's your approach to scaling?" — Bad answer: "We increase budget." Good answer: "We test new creatives, new audiences, new platforms, and only scale spend on what's proven to be profitable at current levels."

"How do you coordinate with email/SMS?" — If paid media and retention operate in silos, you're wasting money acquiring customers you can't retain. The best setup is either one agency handling both or two agencies that actually talk to each other weekly.

"What happens when ROAS drops?" — Every ad account has bad weeks. The question is how the agency responds. Good agencies have a diagnostic framework. Bad agencies just blame the algorithm.

Red Flags

• Guaranteed ROAS — Nobody can guarantee a specific ROAS. The platforms change, competitors adjust, and creative fatigue is real. Guarantees are sales tactics, not commitments.
• Reporting only on platform ROAS — Platform-reported ROAS is always inflated. If the agency doesn't use a third-party attribution tool, you don't actually know your real numbers.
• No creative team — In 2026, media buying without creative production is like having a race car with no fuel. If the agency expects you to provide all the creatives, you'll be the bottleneck.
• They won't share the ad account — Your ad account should live on your business manager, not theirs. If they insist on owning the account, they're holding your data hostage.
