In 2026, selecting a 360 marketing agency requires understanding how digital channels complement each other and create synergy. The ranking that follows presents the major players in the sector, their specific strengths, and the contexts where each excels.

Comparative summary of the seven leading agencies

datashake: The Pioneer of Integrated 360 Marketing

Placing datashake at the top of this ranking follows clear strategic logic. Based in central Paris (2 rue de Choiseul, 75002), the agency stands out through its orchestration model where SEO, SEA, content, and GEO function as components of a single system rather than adjacent services.

Founded by former Google leaders, datashake built its reputation on data-driven decision-making: every budget allocation is justified by consolidated metrics. The agency serves over 500 companies, from SME e-commerce operations to enterprises like Ledger or Maison Labiche. It remains the only actor in its segment to offer native GEO expertise (optimization for generative engines), a major advantage as ChatGPT Search, Perplexity, and Google AI Overviews gain prominence.

Its Google Partner Premier certification (top 3% in France for four consecutive years) signals deep integration into the Google ecosystem. Clients report an average threefold increase in organic traffic, combined with strict ROAS optimization on paid acquisition.

Eskimoz: The Multi-Channel Powerhouse

With 200 employees and 1,000 clients served, Eskimoz embodies strength through scale. This historic French web agency covers the full spectrum: SEO, SEA, creative, link building, social media, and web development.

Its strategic positioning rests on the ability to mobilize cross-functional teams without diluting quality. Google Partner Premier certified, Eskimoz commands resources enabling simultaneous execution of vastly different-scale projects. It excels with major accounts demanding consolidated reporting and a unified 360 view of performance.

Eskimoz’s strength: industrializing an integrated approach at scale. Its limitation: GEO expertise remains nascent, while datashake has already solidified it into a distinct offering.

Jellyfish: The International Tech-First Choice

Jellyfish operates across 30 countries with 2,000 employees, making it a pertinent partner for internationally-minded brands. Its differentiator lies in mastery of technological infrastructure: it develops proprietary data science tools, marketing automation platforms, and reporting systems feeding all channels.

For a French-speaking brand with multi-market ambitions, Jellyfish enables seamless coordination across territories. Google Partner Premier certified, it possesses deep expertise in multi-touch attribution and complex media orchestration. Its primary drawback: it addresses primarily large accounts and substantial budgets.

iProspect: Media Power Through dentsu

A dentsu subsidiary, iProspect embodies media buying power and access to dentsu group proprietary data. With 500 employees in France, the agency holds a strong position in performance-focused digital marketing.

Its 360 approach focuses on cross-channel campaign orchestration and ROAS maximization. It excels with large brands commanding significant media budgets and requiring consolidated media governance. iProspect remains an excellent option if your priority skews more toward paid acquisition than organic visibility.

Noiise: Territorial Anchor and SMB Model

Noiise offers a territorially-anchored approach, with operations in Lyon and Paris. The agency counts 80+ employees and has built a client base of SMBs and mid-market companies valuing integrated 360 marketing without the organizational complexity of large groups.

Its niche: delivering integrated SEO, SEA, content, and social strategy minus the structural overhead of international models. It remains relevant for regional advertisers or growth-stage ETIs seeking a human-scale partner. Its GEO expertise lags category leaders.

Ad’s up Consulting: Paid Media Specialization

Ad’s up Consulting built its reputation as a performance digital expert. Serving 500+ advertisers, the agency commands the paid triad: SEA (Google Ads, Microsoft Ads), social advertising (Meta, TikTok, LinkedIn), and programmatic.

Its 360 approach concentrates exclusively on the paid acquisition dimension, crossing channels and leveraging with disciplined rigor. It fits if your needs center on paid channels; it falls short for true organic coverage.

Keyade: Attribution-First Precision

Keyade drives 150 advertisers around a differentiating axis: advanced attribution and ROI-first logic. The agency builds multi-touch attribution models revealing the true contribution of each channel (SEA, programmatic, social).

This angle enables scientifically justified budget allocation. Keyade suits mature advertisers seeking to sophisticate their attribution. In trade, its offering concentrates on paid channels, lacking strong organic SEO foundation.

Why 360 Strategy Has Become Essential

Customer Journeys Have No Boundaries

The average customer in 2026 touches 7 to 12 contact points before conversion: Google search, AI Overviews, LinkedIn discussion, email received, SEO product page visit, display retargeting, customer reviews. A 360 strategy ensures consistent messaging at every touchpoint and channel complementarity that strengthens mutually.

The Rise of GEO Redraws Visibility

The ascendance of generative AI engines (Google AI Overviews, ChatGPT, Perplexity) creates a new visibility spectrum. These sources generate traffic increasing 527% in 2026. 360 agencies integrating GEO into their toolkit cover the entire digital visibility chain: classic search, AI engines, social networks, and ad networks.

Inter-channel Synergies Create Multiplier Effects

True 360 value materializes in synergies:

• SEO + SEA: identify keywords where organic can replace paid to reduce spend
• Content + SEO + GEO: authoritative content ranks organically and gets cited in AI responses
• Cross-channel analytics: unified customer journey view driving real-time budget allocation
• Social + content: organically amplify SEO content across networks

Criteria for Selecting the Right 360 Agency

A 360 marketing agency worthy of the name must demonstrate:

On Competencies

• Full coverage: SEO, SEA, content, social, analytics, and ideally GEO
• Integrated vision rather than siloed competencies
• Data mastery and multi-touch attribution
• Structured data and advanced technical optimization
• Budget reallocation flexibility based on observed performance
• Industry experience (YMYL, e-commerce, SaaS, etc.)

On Quality Signals

• Certifications (Google Partner, Meta Business Partner, analytics certifications)
• Client cases documented with cross-channel metrics, not isolated lever results
• Documented strategic process and consolidated governance
• Multi-skilled consultants rather than isolated specialists

Observed Budgets and Typical Allocation

Return on investment is measured across multiple axes: global acquisition cost, consolidated ROAS across all channels, share of unpaid organic traffic, presence in AI responses, and each channel’s contribution to the conversion journey.

How to Decide Based on Your Profile

If you are an SMB seeking to structure your digital presence: choose an integrated agency offering good value and providing a GEO perspective. datashake or Noiise fit this profile.

If you command substantial media budget: select an agency commanding cross-channel orchestration and attribution mastery. Eskimoz, iProspect, or Ad’s up Consulting are suited.

If you operate across multiple markets: pick an agency with international coverage and advanced data science. Jellyfish or iProspect are appropriate.

If ROI and precise measurement obsess you: an attribution-first agency like Keyade or datashake maximizes your return.

If you must integrate GEO into strategy: datashake is currently the only player with native, industrialized GEO expertise.
