Top 5 e-commerce acquisition agencies in France in 2026

An acquisition agency means entrusting your media budget to someone else: the larger that budget grows, the more a mediocre agency costs you, and the more a great agency pays for itself. Here is our comparison of the 5 most reliable French agencies to manage e-commerce site acquisition in 2026.

Comparison table of the 5 best e-commerce acquisition agencies

Our detailed ranking of the best e-commerce acquisition agencies

1. Growth Room

Growth Room builds its offering around four levers: Growth Ads (Google, Meta, LinkedIn, Pinterest), Growth Outbound (semi-automated digital prospecting), SEO, and HubSpot CRM integration. The agency supplements this foundation with ABM and RevOps when the project calls for it.

What truly sets Growth Room apart is the lack of silos between these levers. Many agencies excel at a single channel; here, the same team manages paid media, outbound, and SEO, making them work in tandem with a CRM that centralizes everything. For an e-commerce brand that also sells B2B, or one that wants to stop managing four different providers, it is a significant boost in efficiency and consistency.

The agency is built on three pillars:

• expertise in paid channels, lead generation, and SEO;
• data, with a strong focus on campaign traceability and analysis;
• and the responsiveness of a boutique agency rather than a large corporation.

It works with both startups and major accounts, in B2B and B2C, across a variety of sectors: tech, e-commerce, services, education, and healthcare.

Some of the clients we have supported: Devialet, Toyota, Poiscaille.

2. Deux.io

Deux.io takes a different approach than the rest of the list: organic traffic rather than paid. The agency has over ten years of experience and has worked with more than 600 clients from offices in six major French cities (Paris, Lyon, Nantes, Bordeaux, Lille, Marseille), with a division specifically dedicated to e-commerce SEO.

Their method combines technical aspects (site structure, performance), semantics (keyword research, content), UX, and analytics, through audits, prioritized roadmaps, and ongoing copywriting. This is the type of agency you choose to build a lasting asset: unlike paid media, SEO traffic doesn't stop the day you cut the budget.

The trade-off is well-known to anyone who has done SEO: results take several months to appear, which makes Deux.io less suitable for immediate sales needs.

Some of the clients we have supported: Saint Gobain, Luko, Grosbill.

3. Ben&Vic

Ben&Vic checks all the boxes for certifications: Google Premier Partner, plus partner status for Meta, TikTok, Pinterest, and Snapchat. In practical terms, this translates into a genuine ability to activate all paid social channels simultaneously, without outsourcing any specific channel.

The difference compared to a pure media buyer is the integrated creative studio: the agency produces the videos and UGC content that fuel the campaigns itself, rather than just optimizing creative provided by the client. A third division, CRM and retention, extends the acquisition process by working on customer lifetime value after the first purchase.

The agency reportedly manages over 20 million euros in advertising budgets, both in France and internationally. This positioning is particularly well-suited to DTC brands (beauty, lifestyle) that need constantly refreshed creative content to fuel their campaigns.

Some of our clients: Kipli, Yves Rocher, Respire.

4. Pickers

Pickers, based in Paris and Lyon, plays the versatility card with three internal divisions: SEA (Google Ads, Bing Ads, Google Shopping), SEO, and content creation (video, motion design, social media). The idea is to cover both paid and organic acquisition without having to juggle multiple providers.

The agency has worked with over 300 clients since its inception in 2016 and holds triple certification as a Google Premier Partner, Meta Business Partner, and TikTok Marketing Partner. It is a solid option for a company that wants a single point of contact for SEA and SEO rather than two agencies that don't communicate with each other.

Some of our clients: Compagnie des Alpes, Nexity, Radio France.

5. Yateo

Yateo rounds out this list with twenty years of experience and a clear focus on Google Shopping and product feed management: distributing catalogs on Google Merchant Center, continuous campaign optimization, and regular reporting with budget recommendations.

Their business model also stands out: the agency ties a portion of its compensation to the results achieved, rather than charging solely for time spent. They report an average ROI of over 7 on their Google Shopping campaigns and hold the Google Premier Partner badge.

Yateo goes beyond simple acquisition, with a website design business (claiming 500 projects) and status as a PrestaShop Platinum partner. A good choice for a large product catalog, though perhaps less suited for a brand looking strictly for a specialized growth partner on a single channel.

Some of our clients: Eurostar, Paris Saint-Germain, L'Oréal Paris.

Why does the agency matter as much as the media budget?

We often think in terms of commission percentages or hourly rates, forgetting the most important thing: two agencies with the same budget and the same channels can produce vastly different results. The difference lies in the management, not in access to the advertising platforms themselves, which anyone can open in five minutes.

A good e-commerce acquisition agency structures campaigns around product margins, not just click volume. It continuously tests creatives rather than letting the same visuals run for months, sets up tracking correctly to attribute sales to the right channel, and knows how to say no to poorly spent budget rather than burning it just to justify its retainer. Conversely, a mediocre agency might run campaigns that look good on paper (traffic, clicks) while destroying actual profitability.

Criteria for choosing your future e-commerce acquisition agency

The first criterion is the actual scope of your needs: a single agency for all channels, like Growth Room or Pickers, simplifies management, but a highly specialized firm (like Ben&Vic for DTC paid social or Yateo for Shopping) can go deeper into a specific channel.

The billing model is worth a close look. A fixed percentage of media spend doesn't always incentivize an agency to optimize costs; a performance-based model, like Yateo's, aligns interests more effectively, but you must verify how performance is measured before signing.

Certifications (Google Partner Premier, Meta Business Partner, Klaviyo or Shopify partnerships) provide a serious indicator, provided you verify them directly on the platforms' official pages rather than relying solely on what the agency displays.

Client references count for double: beyond the logos, it is better to ask to speak with a current client in a sector or with a sales volume comparable to yours to verify that the results shown are reproducible.

Finally, reporting frequency and team availability during the contract often make the difference over the long term: an agency that manages things closely communicates regularly, not just when it's time to renew the contract.

To go further

This ranking compares agencies with intentionally different profiles: multichannel generalists, ROAS specialists, DTC experts, SEA/SEO duos, or Google Shopping powerhouses. The right choice depends primarily on which channel currently drives the most acquisition, your available budget, and your sector. An initial conversation with two or three agencies from this list, with your budget and profitability goals on the table, will quickly show you which one is the best fit.
