The problem: investing without knowing what really works
The digital marketing industry in France generated 14.4 billion euros in direct revenue in 2024 and supports more than 310,000 jobs (Alliance Digitale & EY, 2025). The market is exploding, channels are multiplying — and so is confusion.
The real cost? It's not advertising spend. It's the cost of inaction: months of delay in Google rankings, prospects choosing better-positioned competitors, a broken customer journey before the first contact. Whether you sell B2B or B2C, the conclusion is the same: without a structured strategy, every passing day widens the gap.
The signals that don't lie
Stagnating organic traffic
You publish regularly, but your Google visibility isn't growing — every week without structured SEO widens the gap with your competitors.
Ad budget without measurable returns
Your Google Ads campaigns consume budget without generating enough qualified leads — due to imprecise targeting and lack of continuous optimization.
Social media without conversion
Likes, impressions, followers… but rarely meetings. Engagement doesn't turn into a commercial pipeline without a results-oriented editorial strategy.
Invisible in AI responses
Your competitors already appear in ChatGPT and Google's AI Overviews. This is a space that most companies still ignore — and it's radically changing the rules.
At NUKLEAR, digital marketing isn't a checklist of services. It's an integrated mechanism where each channel reinforces the others.
What distinguishes our approach? Transparency. Each month, you receive a clear report with the KPIs that really matter: cost per lead, conversion rate, return on investment per channel. No unnecessary jargon, no cosmetic metrics. Data-driven marketing in practice, not just in the pitch.
Attract
We position your brand where your prospects search — on Google, on social networks, and now in AI-generated responses (GEO/AEO). Technical SEO, high-value content, ultra-targeted paid campaigns.
Convert
Traffic alone is never enough. Every landing page, every form, every user journey is designed to reduce friction and increase conversion rates. CRO, A/B testing, optimized sales funnel.
Retain
A retained customer costs five to seven times less than acquiring a new one. Value-added content, automated sequences, reactivation strategy — we build lasting relationships.
SEO — Organic search and lasting authority
SEO is the foundation of any profitable digital marketing strategy. According to BrightEdge data, organic search generates on average more than 53% of web traffic. We handle complete SEO audits, technical optimization, content strategy and link building to build lasting authority in your sector.
SEA — Google Ads, Meta Ads and targeted advertising
When you need immediate results, paid advertising takes over. Our certified experts manage your Google Ads, Meta Ads, LinkedIn Ads and TikTok Ads campaigns with a clear objective: maximize your ROAS and reduce your cost per acquisition.
Social Media — Community management and social ads
Social media isn't a broadcasting channel. It's a conversation space. Our community managers build your presence on LinkedIn, Instagram, Facebook and TikTok with an editorial strategy designed for your audience and commercial objectives.
Content Marketing — Content that attracts and converts
Content marketing is the fuel for your organic visibility. Blog articles, white papers, case studies, podcasts, snack content for social networks — we produce content that positions your expertise and feeds your conversion funnel.
GEO & AEO — Being cited by AIs, not just indexed
This is the emerging playing field of digital marketing in 2026. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) have a precise goal: making your brand appear in ChatGPT, Perplexity, Gemini and Google's AI Overviews responses.

FAQs
Whether you're at the idea stage or already in development, you'll find the essentials here to understand our approach and how we realize your digital ambitions.
The budget varies depending on ambition and activated channels. An SEO strategy alone starts at a few hundred euros per month; a complete multi-channel strategy (SEO + SEA + social media + content) generally represents between 2,000 and 10,000 € per month depending on scope. We build custom offers after a free initial audit.
Google SEO produces its first visible effects between 3 and 6 months. Gains then accelerate cumulatively. In SEA, results are immediate from campaign launch. That's why we often recommend a combined strategy: SEA for immediate acquisition, SEO for sustainability.
GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) designate techniques for appearing in AI responses — ChatGPT, Perplexity, Gemini, Google's AI Overviews. In 2026, a growing portion of searches happens through these interfaces. Ignoring this channel means leaving visibility to your competitors.
SEO aims for lasting organic positions. SEA uses paid advertising for immediate visibility. Both are complementary — which is why we often integrate both in the same digital marketing strategy.
Building a complete internal team represents a considerable salary investment. By outsourcing, you access all the skills (SEO, SEA, social media, analytics, content) with complete flexibility and controlled costs.
Complete tracking setup (GA4, GTM, conversion APIs). Tracked indicators: conversion rate, cost per lead, cost per acquisition, advertising ROI (ROAS), organic traffic growth, social media engagement. We produce clear, actionable monthly reports.
A freelancer excels at a specific mission. An agency like NUKLEAR intervenes when you need an integrated multi-channel strategy. The agency advantage: an overall vision, complementary resources and continuity even in case of absence.
No, we support both B2B and B2C. For B2B: SEO, LinkedIn Ads, content marketing, lead generation. For B2C: shopping campaigns, Meta Ads, social ads, e-commerce SEO. The approaches differ, the standards remain the same.
Yes, integrated into a global strategy: B2B/B2C email campaigns, automated lead nurturing sequences, value-added newsletters — managed with tools like HubSpot, Brevo or Klaviyo.
Our clients are mainly based in France, Belgium, Switzerland and Luxembourg. We work for French-speaking companies as well as international organizations wishing to develop their presence in French-speaking markets.
