Top 10 best SEO agencies in Paris in 2026

Eskimoz, Datashake, and Gemeos take the top three spots in our ranking of the best SEO agencies in Paris in 2026. Eskimoz stands out for its Global Search positioning, Datashake for its integrated SEO and GEO offering and acquisition-driven culture, and Gemeos for its ability to combine strategy, implementation, and conversion.

The market for SEO agencies remains highly segmented. A large company operating in multiple countries, a B2B startup, and a local business do not have the same priorities or the same need for support.

This comparison helps you identify the agency that best aligns with your site, your internal resources, and your business objectives.

Transparency note: This article was written by the agency Gemeos; we applied the same evaluation criteria to all agencies, including our own.

In summary:

Eskimoz leads the ranking for large-scale Global Search strategies. Datashake takes second place thanks to its integrated SEO and GEO offering, its audit covering more than 100 checkpoints, and its acquisition-driven culture. Gemeos completes the top three for projects that require strategy, implementation, and conversion to work together.

The other agencies cater to more specific needs. Resoneo offers deep technical expertise for large-scale websites. Star Boost focuses on local SEO. 1min30 bridges the gap between SEO, content, CRM, and inbound marketing.

Methodology: how we selected these agencies

We did not rank these agencies based solely on their own Google rankings.

An agency might be excellent at ranking its own site while lacking the resources to manage an international migration. Conversely, a firm well-regarded by major accounts might be unnecessarily cumbersome for an SME looking to optimize twenty strategic pages.

The ten agencies were therefore evaluated using the same criteria.

The data presented in this table was verified on July 31, 2026. No missing figures were estimated based on LinkedIn profile counts or assumed revenue.

Datashake reports having supported more than 1,000 companies and managed over €500 million in media budgets. The agency also highlights an SEO and GEO audit covering more than 100 checkpoints and a proprietary tool for monitoring visibility in generative search engines.

Gemeos reports having supported over 240 companies, with a 4.9/5 rating based on 97 reviews on its website. Trustfolio listed 17 verified reviews and a 4.9/5 rating at the time of our verification.

Sortlist listed 20 members and 41 client reviews for Tactee as of July 31, 2026.

Sortlist listed 26 reviews for Star Boost, whose public offering is primarily focused on local SEO and Google Business Profile.

1min30 reports having supported over 450 clients since its inception in 2012.

The social and environmental report published by Resoneo indicates that it was founded in 2004 and has a staff of 95 consultants.

1. Eskimoz

Overview and positioning

Eskimoz no longer positions itself exclusively as an SEO agency. Its current focus is on Global Search.

The idea is to follow the user's actual journey. A search might start on Google, continue on TikTok or Reddit, and then conclude in ChatGPT, Gemini, or a marketplace.

The agency therefore combines several levers designed to improve visibility and acquisition across all these platforms. Its website states that it has supported over 2,000 companies since 2010.

Things to consider: this level of coverage may be overkill for a small business looking only for a technical audit or a few local optimizations.

Specialties and expertise

The main areas of expertise highlighted by Eskimoz are:

• technical, semantic, and international SEO;
• GEO and visibility in generative search engines;
• paid media, SEA, and retail media;
• content production and social search;
• data, tracking, and conversion optimization.

Eskimoz also has a proprietary platform designed to centralize acquisition data, facilitate collaboration, and track performance. The agency also offers several tools related to crawling, content, and LLM monitoring.

This scope allows for cross-referencing insights from different channels. For example, SEA data can help the SEO team identify the queries that actually drive conversions.

Results and client references

Eskimoz publishes case studies in SaaS, e-commerce, finance, real estate, and services.

The agency notably reports a fourteenfold increase in lead generation for Homunity. It also highlights a gain of over 50,000 organic visits in six months for Trainsweateat and a fourfold increase in traffic for Esprit Padel Shop. These figures are taken from case studies published by Eskimoz.

As of July 31, 2026, Trustpilot showed a rating of 5/5 based on 54 reviews. Thirty evaluations had been published over the last twelve months, and 98% of the reviews gave five stars.

Recent comments mention audits, migrations, ongoing support, and projects combining SEO and GEO.

Indicative pricing

Eskimoz’s services are available upon request.

The agency does not publish a price list for audits, monthly support, or international deployment.

To compare their proposal with other agencies, ask for a breakdown of:

• management and consulting;
• content production;
• technical implementation;
• netlinking;
• paid media;
• proprietary tools;
• GEO tracking;
• international coordination.

Ideal for...

Eskimoz is for mid-sized companies, large accounts, scale-ups, and e-commerce businesses looking to drive a Global Search strategy with high production capacity and a combination of multiple areas of expertise.

2. Datashake

Overview and positioning

Datashake is a digital acceleration group founded in 2019 by two former Google employees. Its positioning combines SEO, GEO, and paid acquisition, with in-house expertise used to manage the entire strategy.

The group reports supporting more than 1,000 companies and managing over €500 million in media budgets. This acquisition-driven culture allows it to connect organic visibility with data from other channels, particularly to identify the queries and content that genuinely contribute to performance.

Watch-out: the breadth of the offering and the group’s organization may be less suited to a small business seeking only a one-off SEO assignment or highly local support.

Specialties and expertise

Datashake’s core areas of expertise include:

• technical, semantic, and competitive SEO audits;
• content strategy and production;
• link building and authority development;
• visibility monitoring in Google and generative search engines;
• SEA, paid social, and acquisition campaign management.

Its SEO audit is based on a framework of more than 100 criteria. The analysis covers technical obstacles, website structure, semantic positioning, content, and authority.

The agency has also developed a GEO offering designed to measure and improve brand visibility in ChatGPT, Perplexity, and Google AI Overviews. This approach notably seeks to understand the sources used by generative engines and the factors associated with brand citations.

Results and client references

Datashake lists Chanel, Société Générale, Cheerz, Shine, MAIF, Kujten, and Ladurée among its references. This portfolio demonstrates its ability to work with companies operating under a variety of business models, ranging from finance and e-commerce to luxury goods and digital services.

The group also holds Google Partner Premier, Meta Business Partner, TikTok Marketing Partner, and Microsoft Advertising Select Partner status. These certifications mainly concern its advertising expertise, but more broadly illustrate its level of partnership with the major acquisition platforms.

Indicative pricing

Datashake’s SEO and GEO services are quoted on request.

To compare its offering with those of other agencies, it is useful to request a detailed breakdown covering:

• audit and strategy;
• monthly management;
• content production;
• technical optimizations;
• link building;
• GEO monitoring;
• tools and dashboards.

Ideal for...

Datashake is ideal for scale-ups, e-commerce businesses, and large companies looking to bring SEO, GEO, data, and paid acquisition together within the same group.

3. Gemeos

Overview and positioning

Gemeos has established itself as a top choice for companies looking for the best SEO agency capable of combining strategy, technical implementation, and conversion. Unlike approaches that stop at theoretical advice, Gemeos favors an integrated method: the agency works directly on site structure, components, CMS, redirects, performance, and content.

While the agency has a long-standing expertise in Webflow, it now supports SEO projects across all ecosystems (WordPress, Shopify, Prestashop, HubSpot CMS) and custom architectures. Its services primarily target startups, scale-ups, and B2B companies looking to turn organic visibility into a tangible growth driver.

Things to consider: Gemeos has a more limited international deployment capacity compared to large networks with physical offices in multiple countries.

Specialties and expertise

Gemeos’ core areas of expertise include:

• technical, semantic, and GEO audits;
• market analysis and keyword mapping;
• technical implementation and CMS development;
• content strategy, copywriting, and optimization;
• link building, performance tracking, and conversion rate optimization (CRO).

The agency begins with an analysis of the site's current state (indexing, Core Web Vitals, internal linking, backlinks), then prioritizes actions based on their business impact. The GEO component complements traditional SEO by focusing on answer clarity, structured data, and brand visibility in generative search engines (ChatGPT, Perplexity, Gemini).

Results and client references

Gemeos holds a 4.9/5 rating from 97 reviews on its website. At the time of our review, Trustfolio also listed 17 verified client reviews with a 4.9/5 rating.

The Koncile project illustrates the synergy between redesign, editorial architecture, and SEO. The strategy launched in March 2025 with the creation of thematic content silos focused on OCR and data extraction.

For Modjo, the testimonial published by the agency highlights a 58% increase in engagement rate following a comprehensive redesign. These projects confirm the agency’s methodology: working on the site, content, and conversion within a unified framework.

Indicative pricing

Gemeos publishes the following ranges:

These amounts are indicative and vary based on project complexity. Gemeos also offers multidisciplinary teams (design, Webflow, CRO) starting at €2,400 excl. tax per month.

Ideal for...

Gemeos is ideal for startups, scale-ups, and B2B companies looking for a team capable of designing an ambitious SEO and GEO strategy, implementing it directly on their CMS, and improving traffic conversion.

4. Qwamplify

Overview and positioning

Qwamplify integrates Search into a broader marketing, media, and sales activation offering.

The group reports 170 employees and a history spanning over 25 years. Its current operations primarily highlight programmatic advertising, performance, acquisition, and consumer activation.

This breadth of services can simplify governance for a brand already working across multiple channels.

However, it makes their SEO positioning less clear than that of a specialized agency. Buyers should therefore verify the exact role of Search within the proposal.

Key consideration: Qwamplify’s public pages provide little documentation on their SEO methodology and recent organic results.

Specialties and expertise

The main areas highlighted by Qwamplify are:

• performance marketing;
• programmatic buying;
• email and SMS acquisition;
• sales activation and drive-to-store;
• data and marketing platforms.

SEO can be integrated into this type of setup when organic search needs to be coordinated with paid acquisition, content, and conversion data.

To evaluate the proposal, ask which consultants will be handling the SEO, what deliverables will be produced, and what portion of the budget will be allocated to the organic channel.

Results and client references

Qwamplify showcases work for Manitou, Hyundai, Rolesco, and other brands.

For Manitou, the group developed a multilingual platform that centralizes several years of data to track the performance of an activation program.

The Hyundai case involves a strategy designed to reach prospects at different stages of the buying journey for 65 distributors.

These references demonstrate an ability to manage complex projects. However, they do not allow for the isolation of SEO performance.

Indicative pricing

Services are quoted upon request.

The proposal should break down:

• SEO fees;
• media spend;
• content production;
• tools;
• development;
• activation;
• overall management.

Without this breakdown, it becomes difficult to compare the cost of SEO services with those of a specialized agency.

Ideal for...

Qwamplify is ideal for national brands and groups looking to integrate Search into a broader media, performance, activation, data, and loyalty strategy.

5. iProspect

Overview and positioning

iProspect approaches SEO at the scale of large advertisers.

The network boasts over 8,000 media specialists. Its model is built on connecting media, content, commerce, and performance data.

Organic search is therefore integrated into a wider ecosystem. This structure allows for the cross-referencing of organic data with paid search, retail media, social, and conversion data.

It is better suited to companies with multiple marketing teams than to small businesses looking for a single point of contact.

Things to watch out for: the size of the network does not guarantee direct access to the most experienced profiles. The team composition should be clarified before signing.

Specialties and expertise

iProspect's main SEO and media expertise includes:

• technical and editorial SEO;
• search on social and visual platforms;
• optimization for AI-powered search engines;
• paid search, retail media, and programmatic;
• data, UX, CRO, and measurement.

iProspect states that it uses over 40 proprietary solutions or integrated tools in its SEO stack. The agency also works on visibility for TikTok, Pinterest, YouTube, and conversational interfaces.

This approach addresses the evolution of search journeys, which no longer systematically start and end on Google.

Results and client references

The Dubai Properties case study showcases a full-funnel SEO strategy combining keyword research, local optimization, FAQs, structured data, navigation, and Core Web Vitals.

The published results show a 30% increase in domain visibility, a 32% increase in organic traffic, and a 35% increase in real estate bookings. These figures are taken from the iProspect case study.

The value of this case lies in the link established between visibility, traffic, and business results. However, the exact analysis period is not clearly stated in the public excerpt.

Indicative pricing

Services are quoted upon request.

The proposal should specify:

• the teams actually assigned to the project;
• the seniority of the consultants;
• international resources;
• technology costs;
• data access terms;
• ownership of dashboards;
• contract exit conditions.

Best for...

iProspect is ideal for large advertisers looking to connect SEO with their media, commerce, and data investments, with the capacity for international deployment.

6. Optimize360

Overview and positioning

Optimize360 was built on a proximity-based model designed for SMEs, local establishments, and networks.

The agency states it has been operating since 2012 and has supported over 500 clients. It features a team of twelve senior consultants and claims not to outsource its services.

Its sector-specific positioning is particularly evident in hospitality, catering, real estate, healthcare, and retail.

This industry knowledge can reduce the time required to understand the challenges of an establishment or network.

Points to consider: its international deployment capacity appears less developed than that of the top three agencies in the ranking.

Specialties and expertise

Optimize360’s main areas of expertise are:

• technical and editorial SEO;
• local and multi-location SEO;
• GEO and visibility in AI search engines;
• e-commerce SEO;
• online reputation management and Google Business Profile.

The agency covers several CMS platforms, including WordPress, Shopify, Magento, and Prestashop.

Its local offering caters to businesses looking to generate calls, visits, bookings, or directions requests, rather than just website traffic.

Results and client references

Optimize360 displays a 5/5 Google rating on its website, without clearly specifying the number of reviews associated with it on the pages viewed. This rating should therefore be considered as information published by the agency.

The agency also publishes several sector-specific case studies. Its pages notably feature work in hospitality, real estate, e-commerce, and multi-location SEO.

The level of detail varies by case. It is always best to request a reference whose business model and catchment area match your own.

Indicative pricing

Optimize360 indicates that some SEO services start around €500 per month.

The amount can reach several thousand euros for a national strategy, an e-commerce site, or a multilingual project. The agency's guide specifically mentions monthly costs between €500 and €5,000 depending on the scale of the netlinking.

The quote must specify:

• consultant time;
• content volume;
• number of locations;
• netlinking;
• technical optimizations;
• local SEO tracking.

Ideal for...

Optimize360 is ideal for SMEs, retail businesses, hotels, restaurants, real estate professionals, and networks looking to grow their local or sector-specific visibility.

7. Tactee

Overview and positioning

Tactee integrates SEO into website creation, redesign, and digital acquisition projects.

The agency has 20 members according to Sortlist and reports over 120 clients. Its offering is based on four main pillars: SEO, SEA, website creation, and inbound marketing.

This structure is particularly effective when an SEO project depends on a new architecture, a migration, or a CMS change.

This allows SEO to be addressed before the site goes live, rather than several weeks after the redesign.

Things to keep in mind: the specific SEO results are less detailed on the official website than the reviews and references available on Sortlist.

Specialties and expertise

Tactee’s core areas of expertise include:

• SEO audits and strategy;
• copywriting, content, and netlinking;
• SEA and social ads;
• inbound marketing and automation;
• website creation, redesign, and migration.

SEO is integrated into the site architecture, page templates, redirects, and quality assurance testing.

This continuity reduces the risk of losing search rankings due to deleted URLs, non-indexable pages, or a degraded internal linking structure.

Results and client references

As of July 31, 2026, Sortlist showed a rating of 4.99/5 based on 41 reviews.

Feedback frequently highlights their responsiveness, the quality of communication, and the synergy between website creation and SEO.

The agency profile also notes 120 clients and over twenty years of combined expertise across the entities operating under the Tactee brand.

While reviews provide a useful indicator of the client relationship, they do not replace the need to analyze Search Console or Analytics results from a comparable project.

Pricing

Services are quoted upon request.

For a redesign, the quote must distinguish between:

• site design;
• SEO audit;
• the new site architecture;
• content migration;
• the redirection plan;
• user acceptance testing;
• post-launch monitoring.

This breakdown prevents underestimating the portion of the budget actually dedicated to SEO.

Ideal for...

Tactee is ideal for SMEs preparing to build, redesign, or migrate a site and looking to coordinate SEO, SEA, content, and development with a single team.

8. Star Boost

Overview and positioning

Star Boost focuses a large part of its offering on local visibility.

The agency specializes in Google Business Profile, localized searches, online reputation management, and local customer acquisition.

This positioning is well-suited for businesses where a conversion takes the form of a phone call, a booking, a request for directions, or a visit to a physical location.

Things to consider: this strong local focus makes the agency less suitable for large international sites or marketplaces facing complex technical challenges.

Specialties and expertise

Star Boost’s core areas of expertise are:

• local SEO;
• Google Business Profile optimization;
• multi-location strategies;
• review management and online reputation;
• content creation and website development focused on local acquisition.

The agency primarily serves retail businesses, franchises, and networks.

It aims to connect local visibility to concrete metrics: calls, inquiries, reviews, visits, and new customers.

Results and client references

At the time of our review, Sortlist listed 26 client reviews for Star Boost.

The profile features projects in the food, skilled trades, real estate, healthcare, and e-commerce sectors. The services shown combine SEO, website creation, and digital strategy.

The agency’s local pages also feature several testimonials focused on Google profile optimization and review acquisition.

Detailed data isolating the specific impact of local SEO, advertising, and review collection is not published.

Pricing information

SEO rates are not clearly disclosed.

For a business or network, the quote should distinguish between:

• the cost per location;
• the creation or takeover of profiles;
• monthly management;
• review responses;
• local pages;
• content;
• local ranking tracking.

Ideal for...

Star Boost is ideal for shops, professional practices, restaurants, gyms, franchises, and networks whose priority is to generate more local leads.

9. 1min30

Overview and positioning

1min30 treats SEO as one component of an inbound marketing strategy.

Founded in 2012, the agency reports having supported over 450 clients and generated more than 100,000 leads. Its positioning combines content, CRM, HubSpot, and alignment between marketing and sales.

SEO is therefore used not only to attract an audience but also to integrate them into a qualification and conversion journey.

This approach is suitable for companies whose main challenge is not limited to traffic.

Things to watch out for: campaigns are often multichannel, which makes it more difficult to attribute results solely to organic search.

Specialties and expertise

The main areas of expertise at 1min30 are:

• SEO and editorial strategy;
• inbound marketing;
• content production;
• HubSpot and CRM;
• alignment between marketing and sales teams.

The agency advocates the idea that a company must become its own media outlet to build a sustainable audience.

This approach is well-suited for B2B companies that possess strong industry expertise but lack the methodology to transform it into content, leads, and opportunities.

Results and client references

1min30 lists Club Med, Generali, Crédit Agricole, and Deloitte among the companies they have supported.

A case study on Flexico showcases their inbound marketing and SEO content work. The document notes a top ranking for specific target keywords, over ten quote requests per month, and more than twenty press inquiries. These figures are taken from the case study published by the agency.

However, the strategy does not rely solely on SEO. It combines content, acquisition, and brand positioning.

Indicative pricing

Services are quoted upon request.

1min30 provides a page dedicated to its offerings and pricing, but the public data reviewed does not provide a current, comparable SEO rate card.

The quote should break down:

• strategy;
• SEO;
• content production;
• HubSpot;
• CRM;
• paid campaigns;
• sales management.

Ideal for...

1min30 Ideal for B2B companies looking to connect SEO with their content strategy, HubSpot, CRM, and lead generation processes.

10. Resoneo

Overview and positioning

Resoneo possesses some of the deepest technical expertise in this ranking.

Founded in 2004, the firm brings together 95 consultants specializing in search engines and data strategies applied to digital marketing.

Its positioning caters to major platforms, marketplaces, and sites whose performance depends on advanced crawl, indexing, or JavaScript challenges.

Its tenth-place ranking does not reflect a lack of expertise. It is primarily the result of the weight given to pricing transparency, comparable public reviews, and accessibility for various business profiles.

Things to consider: this level of technicality and organization may be unnecessary for a small business with a simple website and limited internal resources.

Specialties and expertise

Resoneo's main areas of expertise are:

• technical SEO;
• log analysis and data;
• content, internal linking, and netlinking;
• marketplaces, images, and videos;
• search applied to engines and AI.

The firm also develops its own tools and research projects.

In 2026, for example, Resoneo published a study covering approximately 60,000 suggestions and 55,000 domain names to analyze the preferred sources suggested by Google across six countries.

Results and client references

Le Groupe Leboncoin has been working with Resoneo since 2017.

The collaboration began with a redesign using React, then expanded to page generation, internal linking automation, and content production.

In 2025, Resoneo received several awards at the Semy Awards, including one for Leboncoin's SEO growth.

This case illustrates the area where the firm provides the most value: large-scale sites, complex technical constraints, and an already structured internal team.

Indicative pricing

Services are quoted upon request.

For a marketplace or a large website, the proposal must separate:

• the initial audit;
• log analysis;
• workshops with technical teams;
• functional specifications;
• user acceptance testing;
• post-launch monitoring;
• proprietary tools;
• content production.

Ideal for...

Resoneo is ideal for marketplaces, large e-commerce sites, JavaScript platforms, and companies with in-house technical teams facing complex challenges in crawling, indexing, or data.

How to choose an SEO agency in Paris?

Start by defining the problem the agency will need to solve.

A drop in traffic after a migration does not require the same skills as a lack of B2B leads or poor visibility in Google Maps. The more specific the need, the easier it will be to compare proposals.

Next, ask for an example of an anonymized deliverable.

You will quickly see whether the agency produces a generic list of recommendations or a roadmap prioritized by business impact and implementation effort.

Also, verify who will actually be working on your account. An agency's reputation does not guarantee that its most experienced consultant will be assigned to your project.

Here are the questions to ask before signing:

1. Who will be doing the day-to-day work?
2. Will the technical recommendations be implemented directly?
3. How much content is included each month?
4. Is the netlinking budget included?
5. Which metrics will be tied to leads or sales?
6. How will visibility in generative search engines be measured?
7. Will the data and dashboards remain accessible after the contract ends?

Finally, a promise of a guaranteed first-place ranking should be a red flag.

An agency can commit to the resources provided, the deliverables, the deadlines, and the quality of execution. They do not control search engine algorithms or the actions of your competitors.

FAQ

What is the best SEO agency in Paris in 2026?

Eskimoz takes the top spot in our ranking thanks to its Global Search positioning, the diversity of its expertise, and its deployment capabilities.

Datashake takes second place for companies looking to connect SEO, GEO, acquisition, and data. Gemeos is better suited to startups and scale-ups that want to combine SEO, GEO, technical implementation, and conversion.

The best choice therefore depends on the type of site, the number of markets, the budget, and the resources available in-house.

How much does an SEO agency in Paris cost?

Structured monthly support generally starts around €1,500, but can exceed €8,000 when the scope includes significant content production, netlinking, multiple languages, or major technical projects.

Gemeos lists basic support packages between €1,500 and €3,000 per month. Optimize360 mentions services starting around €500 per month, with higher budgets for national or e-commerce strategies.

Always compare the deliverables, volumes, and resources mobilized, not just the monthly fee.

How do you identify a good SEO agency in Paris?

A good agency should be able to present a clear methodology, examples of deliverables, comparable case studies, and the actual team members who will be working on your account.

It must also link SEO metrics to business objectives. An increase in impressions has little value if it doesn't generate leads, sales, or sign-ups.

Avoid providers that guarantee a first-place ranking or refuse to detail their netlinking activities.

Should you choose an SEO agency or a freelance consultant?

A freelancer can be a good fit for an audit, a targeted project, or strategic consulting. The relationship is direct and overhead costs are generally lower.

An agency becomes more appropriate when the project requires a range of skills: technical, content, netlinking, development, design, and data.

The choice depends less on the provider's status than on the diversity of the resources required.

How long does it take to see SEO results?

Initial signals often appear between three and six months, particularly after technical fixes or on long-tail keywords.

Significant results on competitive keywords generally take six to twelve months. The timeline depends on the site's authority, the level of competition, and how quickly recommendations are implemented.

A strategy that sits in a shared document for months cannot produce results.

Should an SEO agency offer GEO in 2026?

At a minimum, an agency must know how to measure a brand's presence in generative responses and adapt its content to new search journeys.

GEO does not replace SEO. It is built on the same foundations: an accessible site, useful content, clear answers, an identifiable brand, and credible external sources.

The two disciplines should therefore be managed together rather than sold as two independent strategies.
