A Paris digital marketing agency that runs your online presence end to end

In France, a communications or marketing agency typically charges between €500 and €1,000 excluding VAT per day, depending on its size, location and the expertise involved. These are ballpark figures; there is no official rate card.

Agencies also work on fixed fees: a one-off project (branding, website, campaign) or a monthly retainer for ongoing support. Paris agencies usually sit at the upper end of the range, as do agencies in London or New York in their own markets.

When comparing two quotes, look less at the day rate and more at the scope: number of days, deliverables, who actually works on your account, reporting included. A low day rate with a vague number of days often ends up costing more than a higher rate on a tightly defined scope.

Ongoing digital marketing support from a Paris agency generally costs from around €1,500 to more than €8,000 excluding VAT per month, depending on how many channels are managed (SEO, ads, CRM, content). These ranges are indicative.

On top of that come media budgets paid directly to the platforms (Google, Meta, LinkedIn), which are not the agency’s fee. An initial audit is often billed separately, typically a few thousand euros depending on depth.

At Comeleon, it all starts with a free 30-minute discovery call. We then quote based on the priorities we identify, not a standard package.

There is no official or independent ranking of the best SEO agencies in France. The “top 10” lists you find online are often written by agencies themselves, paid directories or sponsored articles.

Rather than relying on a league table, judge an agency on verifiable criteria:

• concrete case studies with dated, quantified results;
• a clearly explained method, with no “secret sauce”;
• clear reporting tied to your business goals;
• no guaranteed number-one ranking;
• knowing who will actually work on your account;
• a plan for GEO and AI search engines.

Those are the criteria Comeleon asks to be judged on: a transparent audit, costed priorities and results tracked every month.

Choose a digital marketing agency on its ability to connect its work to your revenue, not on the size of its portfolio. The key question is: “How will you measure success?”

A few useful reflexes:

• ask who will actually work on your account;
• insist on an audit or diagnosis before any quote;
• make sure you remain the owner of your ad accounts, CRM and data;
• favour short, reversible commitments;
• ask to see a sample monthly report.

A small agency usually gives you direct access to the experts. A larger one brings more specialist profiles. Both models work as long as governance is clear.

A 360° digital marketing agency runs your entire online presence: strategy, search, advertising, CRM, content and performance measurement. It replaces several specialist vendors with a single point of contact.

The point is not to do everything, but to connect everything. Keywords that convert in Google Ads shape the SEO content plan. Leads flow into the CRM. The dashboard shows which channel actually pays off.

At Comeleon, this service covers audit and strategy, SEO and GEO, search and social ads, CRM and marketing automation, KPIs and content. We work as an extension of your team, with monthly reporting.

An agency brings several areas of expertise immediately; an in-house hire brings deep knowledge of your business. The right choice depends on your size and needs.

A single in-house marketer rarely covers technical SEO, paid campaigns, CRM and data all at once. An agency pools those skills but knows your business less well at the start.

Many companies combine both: an in-house marketing lead who sets direction, and an agency that executes and brings technical depth. That is the model we prefer at Comeleon: we plug into your existing team rather than replace it.

SEO is free in the sense that Google does not charge for organic rankings, but it takes time and skills, and therefore budget. You don’t pay for the click; you pay for the work.

What you can do at no cost:

• create your Google Business Profile;
• use Google Search Console to track your visibility;
• write content that answers your customers’ questions.

What usually costs money: analysis tools, content at scale, technical fixes, link building and the expertise of a consultant or agency.

The key difference with Google Ads: when you stop paying for ads, the traffic stops. A well-ranked page keeps bringing visitors for months.

SEO costs anything from a few hundred euros for a basic audit to several thousand euros per month for full ongoing support. According to La Fabrique du Net, a French agency directory that collects declared project budgets, the median SEO project budget in France is around €5,000.

Indicative benchmarks in France:

• experienced freelance consultant: roughly €400 to €600 per day;
• one-off SEO audit: from under €1,000 to over €8,000 depending on site size;
• monthly agency retainer: often €1,500 to €5,000 and up.

Price depends mostly on scope: technical only, content production, link building, international. Always compare deliverables, not just the total.

The 3 types of SEO are technical SEO, on-page SEO (content) and off-page SEO (authority). They work together; one pillar on its own is not enough.

• Technical SEO: speed, indexing, site architecture, mobile, structured data. It lets Google crawl and understand your site.
• On-page SEO: content, title tags, headings, internal linking. It matches what the searcher is looking for.
• Off-page SEO: backlinks, brand mentions, reviews. It builds your site’s authority.

A fourth area is often added: local SEO, to appear on Google Maps. And now GEO, to be cited in AI-generated answers.

SEO generally takes 4 to 12 months to deliver meaningful results. That is the range Google itself gives in its video on how to hire an SEO, including the time needed to implement recommendations.

The timeline depends on:

• the age and authority of your domain;
• competition on your target keywords;
• how quickly fixes are deployed;
• the volume and quality of content you publish.

Some technical fixes show results within weeks, such as unblocking pages that were not indexed. If you need results faster in the meantime, Google Ads can bridge the gap.

An SEO audit is a full diagnosis of what is holding your site back in search, with a prioritised list of fixes. It covers three areas: technical, content and authority.

A good audit includes:

• analysis of indexing, speed and technical errors;
• the keywords you rank for, and those you are missing;
• comparison with your direct competitors;
• an assessment of your backlink profile;
• a list of actions ranked by impact and effort.

At Comeleon, our visibility audit adds a GEO layer: we check whether your brand shows up in ChatGPT, Perplexity and AI Overviews answers for your key queries.

Yes, links from other websites remain an important signal for Google, as long as they are relevant and earned naturally. Quality matters far more than quantity.

A link from a respected publication in your industry is worth more than dozens of links from directories nobody visits. Google’s spam policies explicitly target links bought to manipulate rankings.

Durable approaches include digital PR, partnerships and reference content (studies, tools, guides) that other sites cite on their own. These mentions also help GEO, because AI engines rely on third-party sources to judge how credible a brand is.

To become visible online, you need to be where your customers search: Google, Google Maps, the relevant social networks and, increasingly, AI assistants. A website alone is not enough.

The foundations:

• a fast, clear website optimised for search;
• a complete Google Business Profile if you serve local customers;
• content that answers your customers’ real questions;
• a consistent presence on one or two social networks, not all of them;
• a steady flow of customer reviews.

Then advertising speeds things up and a CRM turns visitors into customers. That is exactly the scope of our 360° digital service.

To get known on Google, your site first has to be indexed, then answer your customers’ searches better than the competition. Visibility on Google is built through content, technical quality and external mentions.

Practical steps:

• add your site to Google Search Console and submit your sitemap;
• create a Google Business Profile;
• publish pages targeting the questions your customers ask;
• earn mentions and links from respected sites in your industry;
• collect customer reviews.

For immediate visibility, Google Ads gets you on the page as soon as a campaign goes live, while organic search builds up.

Nobody can guarantee a number-one ranking on Google, and Google says so itself in its guidance for businesses hiring an SEO. Be wary of anyone who promises it.

What you can do is maximise your chances on well-chosen queries:

• target specific searches where competition is beatable;
• publish the most useful, complete answer on the topic;
• get the technical side right (speed, mobile, structured data);
• build authority with quality links.

And position one is no longer the only prize: AI Overviews often appear above the results. Being cited in those answers now matters as much as your ranking.

Worldwide, the most searched terms on Google are mostly brand and service names: according to Ahrefs data, “youtube”, “facebook” and “weather” rank among the very top queries, alongside other big platforms.

Rankings vary by country, tool and period. In France, for example, Ahrefs data published in 2026 puts “chatgpt”, “programme tv” (TV listings), “gmail” and “amazon” at the top, with “youtube” close behind.

The takeaway for a business: a large share of searches are navigational, meaning people type a brand name to reach a site. The better known your brand, the more people search for it directly. Brand awareness is an SEO lever in its own right.

Google Ads delivers immediate results for as long as you pay; SEO delivers durable traffic that builds over several months. Most businesses benefit from combining both.

Google Ads makes sense to:

• launch an offer and test a market quickly;
• capture high-intent commercial queries;
• cover the SEO ramp-up period.

SEO makes sense to:

• lower acquisition costs over time;
• cover informational questions earlier in the buying journey;
• get cited by AI engines.

At Comeleon, we use Ads data to identify the queries that convert, then work on them in SEO to gradually reduce dependence on paid traffic.

The cost of a Google Ads campaign depends on the cost per click in your industry and the volume you want: you set your own budget, with no minimum spend. Cost per click ranges from a few cents to well over €10 depending on competition.

Legal services, insurance and home services are among the most expensive sectors according to WordStream benchmarks. Travel, restaurants and entertainment are significantly cheaper.

If an agency runs your campaigns, add management fees, usually a monthly fee or a percentage of spend. For a small business, a serious test typically starts at a few hundred euros per month in media spend, adjusted after the first results.

To show up on Google Maps, create and verify a free Google Business Profile for your business. It is the basic requirement for local SEO.

To rank higher in local results:

• complete every section (categories, hours, services, photos);
• keep your name, address and phone number identical everywhere online;
• ask for customer reviews and reply to them;
• post updates or offers regularly;
• create a page on your website dedicated to your service area.

Google ranks local results on three factors it documents publicly: relevance, distance and prominence.

The 3 most used search engines worldwide are Google, Bing, and then Yandex or Yahoo! depending on the period. According to StatCounter, Google handles roughly 90% of global searches and Bing around 4 to 5%.

The remaining engines each hold a share of a few percent or less, and their order shifts from month to month. Some are strong regionally: Yandex in Russia, Baidu in China, Naver in South Korea. In France, Google is also around 90%, with Bing in second place.

Bing carries more weight on desktop than on mobile. It also powers services such as DuckDuckGo and Ecosia, and part of ChatGPT’s answers. Optimising for Bing is not a detail.

No search engine is objectively “better” than Google: it depends on what you are looking for. Google remains the most comprehensive for general web search, but other tools serve some needs better.

• Privacy: DuckDuckGo or Qwant do not build an advertising profile of the user.
• Sustainability: Ecosia funds tree-planting projects with its revenue.
• Synthesised answers: Perplexity, ChatGPT or Gemini summarise several sources and cite them.
• Professional research: LinkedIn for people, Google Scholar for publications.

For a business, the real question is not which engine is best, but where your customers are. Today they move between Google and AI assistants, and you need to be visible on both.

GEO, or Generative Engine Optimization, covers the techniques that help a brand get cited in answers from AI engines such as ChatGPT, Perplexity, Gemini or Google’s AI Overviews. The term comes from a research paper published in 2023.

Where SEO aims for a position in a list of links, GEO aims for a mention in a written answer. The two go together: AI engines draw heavily on well-ranked pages.

The main levers:

• content structured as short, precise, sourced answers;
• structured data and up-to-date information;
• brand mentions on credible third-party sites;
• a site that AI crawlers can access.

At Comeleon, GEO is built into every SEO engagement.

To get mentioned in ChatGPT answers, your brand needs to appear in the sources the tool consults and be seen as reliable on your topic. There is no magic button or file.

What helps in practice:

• a site that ranks well, since ChatGPT relies on web search results for up-to-date answers;
• pages that answer questions directly, in the first sentence;
• verifiable facts: figures, dates, sources;
• mentions of your brand in the press, comparison articles, reviews and forums;
• not blocking AI crawlers in your robots.txt file.

Control remains partial: AI engines are opaque and change fast. That is why it pays to measure regularly, query by query.

AI Overviews are summaries generated by Google’s Gemini AI that appear at the top of some Google results, with links to the sources used. They launched in the United States in May 2024 and have since rolled out to many markets, reaching France in July 2026 alongside the conversational AI Mode.

For a business, the impact cuts both ways. On informational queries, some users get their answer without clicking. But the sources cited in the overview gain visibility and credibility.

The goal becomes being one of those sources. That requires solid SEO and content designed to be quoted: clear answers up front, facts you can verify, and a recognisable brand.

No, AI is not replacing SEO; it is changing the rules. AI engines rely on indexed web pages to build their answers, so without good SEO, your chances of being cited are slim.

What is changing:

• fewer clicks on simple questions that AI answers directly;
• more value for expert, sourced and original content;
• growing importance of brand reputation beyond your own site;
• new metrics to track, such as citation rate in AI answers.

SEO remains the foundation and GEO builds on top of it. That is why at Comeleon we handle them together rather than as two separate services.

You measure visibility in AI search engines by regularly asking ChatGPT, Perplexity, Gemini and Google a panel of key questions, then recording whether your brand is cited, where, and from which source.

Useful metrics:

• brand citation rate across a panel of queries;
• share of voice against your competitors;
• which of your pages are cited as sources;
• referral traffic from chatgpt.com, perplexity.ai and other assistants, visible in Google Analytics.

Specialist tools automate this tracking, but results vary from one session to the next, so think in trends. We include these metrics in our clients’ monthly dashboard.

The most effective marketing is the one that reaches your customers where they make decisions, at an acquisition cost lower than the value they bring you. No single channel is best for everyone.

A few pointers:

• in B2B, SEO, LinkedIn and email are often the most profitable;
• in B2C, social ads and local SEO tend to perform well;
• for retention, email and marketing automation cost little and return a lot.

Real effectiveness comes from combining channels and measuring them. Test two or three, measure the cost per customer actually acquired, then concentrate budget on what works. That is the KPI-driven approach we apply.

The 4 Cs of marketing are Customer, Cost, Convenience and Communication. Robert Lauterborn proposed the model in 1990 to replace the 4 Ps (Product, Price, Place, Promotion) with a customer-centred view.

• Customer: start from real needs, not from the product.
• Cost: everything the customer gives up, not just the price (time, effort, risk).
• Convenience: how easy it is to access and buy, online or in store.
• Communication: a dialogue with the customer rather than one-way promotion.

In digital marketing, the 4 Cs are very concrete: a fast site and a simple checkout are about convenience; a CRM and replies to reviews are about communication.

The underlying marketing trend for 2027 is the shift from classic search to AI-powered search, which forces brands to be cited, not just clicked. The trends below are projections, not certainties.

• GEO: the spread of AI Overviews and AI Mode accelerates conversational search.
• AI-driven campaigns: targeting and bidding are increasingly automated on Google and Meta.
• First-party data: CRM and email matter more as third-party targeting becomes more restricted.
• Verifiable expertise: value is shifting to expert opinion, original data and proof.
• Automation of marketing tasks by AI agents.

At Comeleon, these topics are already part of our client work.

The essential digital marketing KPIs are the ones that connect your actions to revenue: customer acquisition cost, conversion rate, number of qualified leads and return on investment by channel.

A typical set for a small or mid-sized business:

• organic traffic and rankings on key queries;
• website conversion rate;
• qualified leads and cost per lead;
• customer acquisition cost (CAC);
• return on ad spend (ROAS);
• customer lifetime value (LTV);
• citation rate in AI engines.

Five to eight metrics reviewed every month beat forty that nobody looks at. Impressions or follower counts are only useful to explain the main KPIs.

The best CRM for a small business is the one your team will actually use: simple, connected to your website and tools, and sized for your current volumes. The brand matters less than adoption.

Common options:

• HubSpot: very complete on marketing, with a free tier to get started;
• Brevo: a French platform, strong on email and automation;
• Pipedrive: focused on sales tracking and pipeline;
• Salesforce: suited to larger organisations or complex processes.

Before choosing, map out your sales stages, lead sources and the automations you need. At Comeleon, we configure and connect the CRM, then build the automation workflows around it.

Marketing automation means automatically triggering marketing actions (emails, follow-ups, notifications, lead assignment) based on your contacts’ behaviour or profile. It takes the repetitive work off your team’s plate.

Concrete examples:

• a welcome sequence after someone downloads a guide;
• an automatic follow-up on an unsigned quote after 7 days;
• an alert to a salesperson when a prospect returns to the pricing page;
• lead scoring that ranks contacts by sales readiness.

With AI, automation goes further: personalised messages, qualification of inbound requests, conversation summaries logged in the CRM. It is one of Comeleon’s three core services.
