French SEO: ranking in France and in French, the legal notices every French site needs, and how to hire a consultant

French SEO means pages written in French by native writers for the words French buyers actually type, on a site that meets French law: the mandatory legal notices (mentions legales), a privacy notice, consent before ad and most analytics cookies, and consent before email or SMS prospecting, except for existing customers buying similar products. Google handles about 88% of searches in France, so the work is Google SEO first. If you also sell in Quebec, treat it as a second market with its own rules and its own French, not as a copy of your France pages.

The French search market in numbers

StatCounter's figures for September 2026 put Google at 88.16% of searches in France, Bing at 5.47%, Yahoo at 2.75%, Ecosia at 1.34%, Qwant at 0.86% and DuckDuckGo at 0.84%. Qwant is a French search engine, so it shows up in French figures more than elsewhere, but Google is where the work is.

On social media, StatCounter's referral figures show Facebook sending 73.63% of the social visits to websites in France, Instagram 9.72%, Pinterest 7.01%, X (Twitter) 3.91%, YouTube 2.33% and Reddit 2.00%.

French or French: France and Quebec are two markets

A company that wants "French SEO" usually means one of two things: reaching buyers in France, or reaching French speakers in Canada as well. They are different jobs. Vocabulary, spelling habits, currency, laws and the search terms themselves differ, so a page written for Paris will not read naturally in Montreal. Give each market its own URL and its own copy, and connect the versions so search engines show the right one. If Quebec is part of your plan, our page on SEO and digital marketing in Montreal, French first by law covers the Quebec side.

For France itself, translated English pages rarely match what French buyers type. Start from French keyword research, then write the page. A native writer who knows your trade is worth more than a polished translation.

The legal notices every French business site needs

The French administration's business portal, Service Public Entreprendre, sets out what a professional website must show, checked on 13 October 2026. For a company, the legal notices include:

• the company name, legal form and share capital;
• the registered office address, an email address and a phone number;
• the registration number in the trade and companies register (RCS) and/or the national business register (RNE), depending on the activity;
• the individual VAT identification number, where it applies;
• the name or company name of the web host, with its address and phone number;
• for a site that publishes content to the public, the name of the publication director.

The notices can sit in the terms of sale or on a dedicated page. The portal states that failing to give them is punishable by a fine of EUR 375,000 for a company and EUR 75,000 for a sole trader, under the 2004 law on confidence in the digital economy (LCEN). An agency that rebuilds your site should keep this page one click from every page.

Privacy, cookies and email consent

• Privacy notice. The site must tell visitors who is processing their data, why, on what legal basis, who receives it, how long it is kept and what their rights are. The portal says a missing item is punishable by a EUR 1,500 fine, and recommends a clearly titled privacy page linked from every page, separate from the terms of sale.
• Cookies. Trackers used for advertising need the visitor's prior consent in principle. Some audience measurement tools can be exempt, but only under precise conditions, for example when they are used solely to produce anonymous statistics. The portal is clear that a cookie does not automatically need consent: each one is judged by its purpose, using the list published by the CNIL, the French data protection authority.
• Email and SMS prospecting. Consent is required for commercial prospecting by electronic means such as newsletters and SMS. The obligation falls away only where the person is already a customer and the prospecting concerns similar products or services.

Ask any agency to show how its tracking setup handles a visitor who refuses cookies, and how its lead forms record consent.

French providers price by monthly retainer, fixed project or day rate. Compare quotes on hours, named people, deliverables and exclusions. Refuse any offer that promises a position: Google's own guidance says "No one can guarantee a #1 ranking on Google." If you read French, our guides to what an independent SEO consultant does and how to choose one and to SEO agencies and search marketing agencies cover the French market in detail.

Paris and the regions

In Paris, local search for a shop, clinic or restaurant works street by street and arrondissement by arrondissement. Own your Google Business Profile, use the real address and opening hours, and add photos of the premises. Outside Paris, in Lyon, Bordeaux, Poitiers or Lille, the same national rules apply, but each city is its own local market: build one honest page per place you really serve. Our French guide to local search and how Google ranks businesses on the map lists what you can fix yourself.

Questions about French SEO

Can one French page serve France and Quebec?

It can be found in both, but it will read as foreign in one of them. If both markets matter, write a version for each and give each its own URL.

Does a foreign company's French site need mentions legales?

The rules on Service Public Entreprendre are written for businesses in France. If you trade in France through a French entity, the notices apply to its site. Ask a French adviser about your exact setup.

Do analytics cookies always need consent in France?

Not always. Some audience measurement can be exempt under precise conditions, such as producing only anonymous statistics. Advertising trackers need prior consent in principle.

Can we email French customers without fresh consent?

Yes, if they are already customers and the email concerns similar products or services. For everyone else, electronic prospecting needs consent.

When can we judge whether French SEO is working?

Read Search Console for impressions, positions and indexed pages on the French URLs, the Business Profile performance report for calls, and your own count of French enquiries by page. The outcome depends on competition, your offer and your budget.

What a French buyer hears from ChatGPT

StatCounter's September 2026 chatbot figures for France give ChatGPT 79.03% of use, Gemini 11.82% and Perplexity 4.62%. When a buyer in Paris asks one of them for a good SEO agency in France, it answers in French with a short list drawn from French directories, trade press, award lists and agency sites. That list is not Google's top ten. AI Knows Us checks it for a business, asking its buyers' questions on ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews and showing which firms are named and which sources each answer cites.
