SEA Agency — Google Ads, Microsoft Ads & ChatGPT Ads
Search advertising is no longer limited to Google. We run Google Ads, Microsoft Ads and the new ad formats of generative AI — to ROI, never to spend.
Optimized to be cited in
SEA (Search Engine Advertising) covers the techniques for buying visibility in search results: Google Ads, Microsoft Ads, and now the ad formats of generative AI. Unlike SEO, SEA produces immediate traffic — but only as long as the media budget is active. It's the lever of fast, controllable acquisition.
What is an SEA agency in 2026?
An SEA agency is a partner that designs, deploys and steers your search advertising campaigns to generate qualified traffic on demand. Concretely, it structures your Google Ads and Microsoft Ads accounts, writes the ads, selects the keywords, sets the bids and continuously optimizes cost per acquisition. In 2026, the scope expands: AI assistants like ChatGPT and Copilot open new ad spaces that capture purchase intent at the exact moment of recommendation. A modern SEA agency no longer just "runs campaigns": it orchestrates paid acquisition across Google, Microsoft and emerging AI surfaces, tying every euro spent to a measurable business result. That's the difference between spending a budget and investing a budget.
SEA generates traffic from the very first day of delivery, versus 6 months for SEO
every campaign is steered to return on ad spend, not click volume
Google Ads, Microsoft Ads and AI ad formats orchestrated together
Google Ads, Microsoft Ads, ChatGPT Ads: the paid search landscape
SEA has fragmented into three complementary territories, and each captures a different intent.
Google Ads
Search, Performance Max, Shopping, YouTube. The major paid acquisition channel in France, where most of the volume and bid competition plays out.
Microsoft Ads
Bing, Edge and Copilot. Often lower costs per click, a qualified B2B audience, and direct access to Microsoft's AI ecosystem via Copilot.
ChatGPT Ads
The emerging ad formats within AI responses. A nascent channel where the first mover captures purchase intent at the moment of recommendation.
Account structure
Campaigns, ad groups and architecture designed for clear steering and quality signals sent to the algorithms.
Ad copywriting
Headlines, descriptions and extensions continuously tested. Ads that qualify the click before it's even paid for.
ROAS-driven steering
Cost per lead, cost per acquisition, return on spend. Every metric visible in real time, never after the fact.
Why ChatGPT Ads change the game for acquisition
ChatGPT Ads is the name given to the ad formats that appear inside the responses of generative AI assistants. It's a break in the logic of paid acquisition: instead of showing an ad against a query, the system offers a recommendation at the precise moment the user asks for advice. Intent is no longer merely declared, it's contextualized and qualified by the entire conversation that precedes it. For an advertiser, this means capturing a prospect at the peak of their purchase readiness, in a trusted environment. The channel is still rolling out, but the history of paid search is clear: those who position themselves early on a new auction format pay less for their clicks and learn faster than their competitors. That's exactly the logic we apply to generative AI with our GEO agency — except here, the lever is paid and immediate. We track these formats closely to place you in them as soon as they open commercially in France.
SEA on generative AI isn't a gimmick: it's the natural extension of search fragmentation. Being present on Microsoft Ads already feeds Copilot. Anticipating ChatGPT Ads means positioning yourself before auction costs climb.
SEA and SEO: two levers that reinforce each other
SEA and organic search aren't competitors, they're two timeframes of the same acquisition strategy. SEA captures demand today: it produces immediate traffic and, above all, it generates valuable conversion data — you know exactly which keywords turn into real customers. This data directly feeds your SEO and GEO strategy, revealing the most profitable intents to work organically. Conversely, a brand already visible in organic results converts its paid clicks better: dual presence reassures and raises click-through rate. That's why we refuse to run SEA in a silo. Our approach orchestrates paid acquisition and the organic foundation together, so each lever feeds the other instead of cannibalizing it. The result: an acquisition cost that drops as the SEO foundation builds.
Our approach: the LUWIZ Method applied to SEA
No campaigns launched on a hunch then left on autopilot. Every SEA engagement follows the four steps of the LUWIZ Method: Diagnosis (account and competitor audit), Foundation (account structure, tracking, ads), Authority (scaling profitable campaigns, channel expansion), Steering (continuous ROAS optimization and transparent reporting). You always know where every euro goes and why.
Full audit of the existing account, competitive bid analysis, identification of budget leaks and untapped opportunities.
Campaign restructuring, reliable conversion tracking setup, writing the first ads and calibrating bids.
Scaling profitable campaigns, ad testing, expansion to Microsoft Ads and preparation of AI ad formats.
Continuous cost-per-acquisition optimization, two full reports per month, ongoing adjustment of the budget mix across channels.
What well-steered SEA changes for your business
A structured SEA account isn't measured by the number of clicks, but by the quality of the customers it brings. The difference between a campaign you endure and one you control comes down to three things: reliable tracking, a clear account structure, and optimization to ROAS rather than volume. Without these foundations, you pay for traffic that doesn't convert and you spray unqualified queries. With them, every euro invested is traceable down to the signed customer. That's the level of rigor we apply, tying SEA to the conversion of your landing pages: attracting a paid click is pointless if the page doesn't convert. To go deeper on the metrics that matter, see our resources dedicated to paid acquisition.
The LUWIZ Method — 4 steps
Diagnosis
AI & SEO visibility audit, mapping of target queries across Google, ChatGPT, Perplexity, Gemini and Claude.

Authority
E-E-A-T signals, external mentions and citations, internal linking that consolidates your topical authority.
Steering
AI share of voice measurement, monthly reporting and continuous optimization of your citations.
Frequently asked questions
An SEA agency buys immediate visibility through ad auctions (Google Ads, Microsoft Ads): you pay for each click, and traffic stops when the budget stops. An SEO agency builds lasting organic visibility that doesn't depend on a media budget. The two are complementary: SEA captures demand today while SEO and GEO build your long-term foundation.
ChatGPT Ads refers to the advertising formats being rolled out inside ChatGPT's responses and those of other AI assistants. It's an emerging channel: advertisers who position themselves early capture ultra-qualified purchase intent, at the moment the user asks for a recommendation. We track these formats closely to place you in them as soon as they open commercially in France.
We recommend a media budget of at least €1,500 per month to generate enough data and optimize comfortably. Below that, the Google Ads algorithm lacks signals to learn. Our management fees are separate from the media budget: you keep total control of every euro spent via your dashboard.
SEA produces traffic from the very first day of delivery. But real profitability builds over 4 to 8 weeks: that's the time needed for the algorithms to learn, for us to test the ads and to eliminate unprofitable queries. We set cost-per-acquisition targets from the start.
Yes. Microsoft Ads (Bing, Edge, Copilot) is often underused even though its costs per click are frequently lower and its B2B audience is qualified. Above all, Bing feeds Copilot and part of ChatGPT's answers: being present there strengthens your visibility within Microsoft's AI ecosystem.
Each campaign is tied to a measurable business goal: cost per lead, cost per acquisition, return on ad spend (ROAS). You track these indicators in real time on your dashboard, with two full reports per month explaining what worked, what was cut and next month's plan.
Yes, and the two reinforce each other. SEA captures immediate demand and gives you valuable conversion data (which keywords actually convert) that feeds your SEO and GEO strategy. Conversely, a brand visible organically converts its paid clicks better. We orchestrate both channels together, not in silos.
Our SEA engagements generally run for a minimum of 6 months, the time it takes campaigns to reach their optimal regime. You keep permanent access to your ad account and your dashboard: full transparency, with no hidden clauses or account retention.
