360 SEO Agency

DualMedia is a 360 search marketing agency based in Paris, specializing in the organic and paid visibility of brands across the entire search ecosystem: traditional engines (Google, Bing), social networks (TikTok, LinkedIn, Instagram, Meta Ads) and generative AI engines (Google AI Overviews, ChatGPT Search, Perplexity, Claude). Since 2000, we have supported SMEs, mid-sized companies, and large enterprises with SEO, SEA, SMM, content marketing, and now GEO (Generative Engine Optimization) strategies for the new AI search engines. Here is our approach, our services, our methodology, and our pricing for modern 360 search optimization in 2026.

What is a 360 search marketing agency?

A 360 search marketing agency covers all of a brand’s visibility levers on the internet, unlike specialized agencies that cover only one aspect (SEO only, Google Ads only, social networks only). The 360 approach ensures strategic consistency across channels, shared use of data (keywords, audiences, content), and optimized return on investment.

The 6 pillars of a 360 search marketing agency in 2026

  • SEO (Search Engine Optimization) : organic search on Google and Bing
  • SEA (Search Engine Advertising) : paid advertising on search engines
  • SMM (Social Media Marketing) : presence and advertising on social networks
  • GEO / AEO / LLMO : optimization for generative AI engines (new discipline 2024-2026)
  • Content Marketing : production of high-value content to feed all channels
  • Analytics & CRO : performance measurement and continuous conversion optimization

Difference between a traditional SEO agency and a 360 agency

Vision Tactical on a single channel Cross-channel strategic
Data sharing Limited to its channel Audiences, keywords, content shared across all channels
Adaptation to AI Often overtaken by changes Natively integrates generative engines

GEO, AEO and LLMO: the new frontier for 2026

It is the revolution that most agencies still underestore. In 2026, around 30 % of informational queries go through generative engines (Google AI Overviews, ChatGPT Search, Perplexity, Claude Search, Microsoft Copilot). Brands absent from these generated responses lose traffic without knowing it.

  • Measurement of mentions of your brand in generated responses (vs competitors)
  • Editorial optimization to become a source cited by LLMs

  • Implementation of extensive structured schemas

AEO (Answer Engine Optimization)

  • Extended FAQ schema
  • Direct and concise formulations favored by Answer Engines (Perplexity, You.com)

LLMO (Large Language Model Optimization)

  • Presence work so that your brand is “known” to LLMs during their training
  • Strengthening Wikipedia, press, academic citations according to the sector
  • Monitoring changes in LLM knowledge about your brand

DualMedia has internally developed a proprietary GEO audit tool based on GPT-5 that measures a brand’s visibility in 5 major generative engines across 100 personalized target queries. It is a unique service on the French market.

SEO in 2026: what has fundamentally changed

The profession has experienced its biggest disruption since the shift to mobile-first in 2018. Three major changes must absolutely be taken into account.

1. Generative engines are capturing a growing share of traffic

Google AI Overviews appears on about 30 % of informational queries in France. ChatGPT Search, Perplexity, Claude Search capture an additional share. Brands absent from generated answers lose traffic month after month without always being aware of it.

2. The Helpful Content Update penalizes unedited AI content

Since the March 2024 Spam Update and its aftermath, Google has severely penalized sites that publish raw, low-differentiation AI content. The test is no longer “is this content generated by AI?” but “does this content add something that cannot be found better elsewhere?”. Editorial added value is no longer optional.

3. Stronger E-E-A-T across all sensitive topics

On YMYL topics (Your Money Your Life — finance, health, legal), Google requires stronger authority signals than ever: identified authors, detailed bios, cited sources, external mentions. Anonymous or poorly documented sites lose visibility.

KPIs and reporting

We track all relevant indicators with you according to your objectives. A few examples by channel:

FAQ — 360 SEO agency

What is a 360 search marketing agency?

A 360 SEO agency covers all of a brand’s visibility levers: SEO (organic search), SEA (search engine advertising), SMM (social media), content marketing, analytics, and désormais GEO (optimization for generative AI engines). This approach ensures cross-channel consistency and data sharing.

What is the difference between an SEO agency and a 360 SEO agency?

An SEO agency works only on organic search. A 360 SEO agency integrates SEO + SEA + SMM + Content + GEO + Analytics, with a cross-channel strategic vision. The 360 approach helps avoid silos, optimize the overall budget, and better understand the user journey.

How much does a 360 SEO service cost?

It depends on the scope. A one-time 360 audit costs between €5,000 and €15,000. A complete monthly strategy ranges from €5,000 to €25,000/month depending on the scope. For an SMB with a single prioritary channel, you can get started from €1,500 per month.

How long does it take to see SEO results?

The first signals generally appear between 3 and 6 months for low-competition keywords, and 6 to 12 months for highly comporitive keywords. SEA and SMM produce results within 4 to 8 weeks after launch. GEO is typically measured over 3 to 6 months.

What is GEO (Generative Engine Optimization)?

GEO is the optimization of a brand’s presence in responses generated by AI engines: Google AI Overviews, ChatGPT Search, Perplexity, Claude, Microsoft Copilot. The criteria differ from traditional SEO: multi-source authority, factual structure, presence on Wikipedia and authority sites, phrasing tailored to LLMs.

Should we really be concerned about AI engines in 2026?

Yes, it has become critical. On around 30 % of informational queries, Google AI Overviews captures attention before traditional organic results. For brands absent from these generated responses, this means invisible but growing traffic loss. Today, GEO is as important as SEO was 10 years ago.

What guarantees do you offer on the results?

No serious agency guarantees specific rankings on Google (algorithms change constantly). On the other hand, we commit to the quality of the work delivered, meeting deadlines, transparent reporting, and achieving intermediate KPIs (complete audit, content produced, technical optimizations implemented).

Do you work with an existing internal team?

Yes. We regularly work as an extended team alongside internal marketing teams: on specialized topics (technical SEO, GEO, automation), in training your teams, or in subcontracting editorial production. Our approach adapts to your governance.

What contractual commitment do you offer?

One-time audits are one-shot. Ongoing services (SEO, SEA, SMM) generally require a 6 to 12-month commitment to produce significant results. Contracts can be terminated with defined notice (typically 30 or 60 days).

How does the start of a project work?

First free scoping meeting (video call or Paris offices) to understand your context and objectives. Detailed commercial proposal within 5 days. If we move forward, complete audit in 2–3 weeks, then gradual activation of the levers over 6 to 12 months according to the roadmap agreed together.
