What are the 5 best SEO and SEA agencies in France in 2026?

Many companies use one agency for organic search and another for Google Ads. Each works on its own list of keywords, with its own metrics, and they rarely communicate. When we take over these types of accounts, we often find paid ads running on queries where the site already ranks first organically. At Growth Room, SEO and SEA are managed by the same team, and this is the criterion we applied to select the five agencies below, starting with our growth marketing agency.

Key takeaways

• An SEO and SEA agency manages organic search and Google Ads using the same data and the same objectives.
• The selected agencies demonstrate expertise in both areas and cite public references.
• Our selection: Growth Room, Eskimoz, Primelis, JVWEB, and Uplix.
• Eskimoz and Primelis primarily work with large accounts and international clients. Growth Room and Uplix focus more on SMEs and scale-ups.
• To choose, look at references in your sector, conversion tracking, and how they account for Google's AI-generated answers.

Why entrust SEO and SEA to the same agency?

With a single team handling both channels, you can:

• reduce or stop ads on queries where the site is already well-positioned organically;
• choose SEO content based on queries that convert in Google Ads;
• test a message in advertising before using it on a landing page;
• track a single acquisition cost in one unified report.

Since the launch of Google's AI Overviews in France in July 2026, a generated answer appears on certain searches between the ads and the organic results. Coordinating both channels prevents paying for space that has shrunk. This is the synergy we strive for on every account.

How did we choose these agencies?

Our criteria:

• SEO and SEA presented as two core areas of expertise;
• publicly cited clients or results;
• a dedicated team for each channel;
• work on AI answers (GEO) or tracking visibility within AI search engines.

Agencies that offer SEA only as an add-on to website creation services are not included in this list.

What are the 5 best SEO and SEA agencies in France?

1. Growth Room: SEO, Google Ads, and GEO in the same team

We are a Paris-based growth marketing agency that has supported over 150 companies. We are Google Ads, Meta Ads, LinkedIn Ads, and HubSpot partners, and the same team manages SEO, SEA, and GEO. Our COO previously led a team at fifty-five, and every consultant personally sets up the tracking conversion tracking, linked to the CRM whenever the client has one.

On Google Ads, our clients see an average of 32% more leads and an 18% reduction in acquisition costs. For Déménager Facile, a moving quote comparison platform, we generated 425 leads in two months with a budget of €15,304. The cost per lead average cost is €29. This was reduced by approximately two-thirds during the campaign after segmenting campaigns across 20 departments and separating the general public from military personnel relocating.

For SEO, we test our methodology on our own site before applying it to our clients. It is described in our GEO Playbook, requested by over 4,000 people: updating existing content, structured data, figures derived from our campaigns, and mentions on other sites.

For whom: SMEs, scale-ups, and mid-sized companies, in both B2B and e-commerce. Details of our offerings can be found on our SEO agencyandGoogle Ads agency.

2. CyberCité: a long-standing search agency

CyberCité has been around since 1999. The agency reports over 130 employees spread across Paris, Lyon, Nantes, Rennes, Chambéry, and Sophia Antipolis. They cover technical, local, and international SEO (log analysis, netlinking), as well as SEA and analytics.

They hold Google Premier Partner status and are a certified Google Analytics Partner. Their data analytics division works on GA4 configuration and conversion tracking, which facilitates a unified view of SEO and SEA results.

Best for: multi-site networks, regional businesses, and sites requiring advanced technical SEO.

3. Primelis: SEO, SEA, and Shopping for international brands

Founded in 2009, Primelis is headquartered in Levallois-Perret with offices in New York and São Paulo. It describes itself as a MarTech agency, combining SEO, SEA, Shopping, social ads, and data into a unified search strategy.

Primelis manages all digital channels for Galeries Lafayette (SEO, SEA, paid social). They began by handling the group's SEO in 2020. The agency has raised 11 million euros to fuel its European expansion.

Best for: retail, e-commerce, and brands expanding internationally.

4. JVWEB: an acquisition agency active since 2004

JVWEB has been working in online acquisition since 2004. Their expertise covers SEO, SEA, social ads, GEO, and data. For SEA, they manage Google Ads, Bing Ads, and Amazon Ads campaigns—a useful feature for brands that also sell on marketplaces.

Best for: companies looking for an established agency with broad SEA coverage.

5. Uplix: a newer agency with its own proprietary tools

Uplix was founded in 2020 in Paris by Emmanuel de Vauxmoret, a former agency director at Eskimoz. The team consists of about forty people, and their business is split equally between SEO and SEA, with Amazon Ads as an additional service. The agency has developed a predictive SEO tool in partnership with OnCrawl and has been granted "Jeune Entreprise Innovante" (Innovative Young Company) status.

Their client references include Engie, Enedis, SNCF, and UNESCO.

Best for: companies that prefer a mid-sized structure with proprietary tools, particularly in the SaaS and services sectors.

Comparison table of SEO/SEA agencies

Which SEO/SEA agency should you choose based on your profile?

• Large accounts operating in multiple countries: Eskimoz or Primelis, both of which have teams abroad.
• Retailers or brands that also sell on marketplaces: Primelis for Shopping, JVWEB for Amazon Ads.
• B2B SMEs or scale-ups looking for qualified leads tracked all the way to the CRM: Growth Room.
• Companies looking for a mid-sized agency with their own proprietary tools: Uplix.

Regardless of the agency, ask them how they choose their keywords across both channels, and how they identify paid ads on queries that are already ranking well organically.

How much does an SEO/SEA agency cost?

Agency fees are in addition to the advertising budget paid to Google. For SEO alone, the ranges published in 2026 generally go from €600 to €5,000 per month, depending on the size of the site and the level of competition. The Google Ads budget depends on the target cost per lead and the desired volume of inquiries. We explain how to calculate this in our article on the budget to plan for Google Ads.

What questions should you ask an SEO/SEA agency before signing?

• How do you use Google Ads data to inform your SEO content strategy?
• What are you doing regarding Google's AI Overviews and the GEO?
