Digital advertising agency in Luxembourg

We run your campaigns.
You watch the results.

Digital advertising is the media buying and campaign management service of AIxH, a digital advertising agency in Luxembourg certified on Google Ads (Google Partner): Google, Meta, LinkedIn and TikTok campaigns, content creation and tracking. 27 years of experience, AI in the engine room, and every campaign tied to a business KPI: leads, cost per appointment, sales.

Certifications

What does a Google Ads certified agency actually guarantee?

AIxH is a Google Partner agency. The Google Partner badge cannot be bought: it is renewed every year, subject to the ad spend under management, performance on client accounts and up-to-date certifications.

Our consultants are certified on the five Google Ads environments we run for you. To understand what the badge really guarantees, read our article Google Ads certified agency in Luxembourg. Grégory Camus's certifications can be checked publicly on Skillshop.

AI-Powered Performance

A digital advertising agency in Luxembourg that knows the Google Ads levers because it works with them every day, certifications to show for it.

Our job is to bring you customers. Traffic on its own is only the raw material.

The difference lies in the level of precision. A click has no value in itself. A qualified appointment with a serious prospect does.

Every campaign is managed by hand, on business indicators: leads, cost per lead, cost per appointment, sales.

AI handles the analysis, the suggestions and the chores that add no value. The trade-offs and the critical optimisations stay with us.

Method

How does AIxH run a campaign?

AIxH runs every campaign in four steps: analysis, KPI definition, continuous optimisation and reporting. No blind automation: every setting that matters is adjusted by hand.

  1. Analysis: No generic pitch deck: an analysis of your account, your historical performance and your market.
  2. KPI definition: Together we define the indicators that really count, which are business results. Impressions and clicks are never the target.
  3. Launch & optimisation: We launch, we optimise, we go again. AI analyses and suggests; the critical trade-offs remain human.
  4. Reporting: Clear reports, with context: what worked, what did not, and why.

“I started doing SEO at the end of the nineties, when you still had to explain what the word meant. Since then the platforms have never stopped changing. The question has not moved: how much does a customer cost you, and how do we bring that figure down.”

FAQ

Frequently asked questions about digital performance

How much does campaign management by AIxH cost?

The budget depends on the platforms activated, the market and the objectives. AIxH does not apply a single price list: the quote is drawn up after a free analysis of your account and your historical performance. Write to hello@aixh.com for a tailored estimate.

Is AIxH Google Ads certified?

Yes. AIxH is a Google Partner agency and its consultants are certified on Google Ads Search, Display, Video, Shopping and AI-Powered Performance. These certifications are renewed every year.

Is AIxH an SEA agency in Luxembourg?

Yes. SEA (Search Engine Advertising, paid advertising on search engines) is the core of the Digital advertising service, with a dedicated Google Ads and SEA offer in Luxembourg: Search, Shopping, Demand Gen and Performance Max campaigns, complemented by Microsoft Ads, run from Differdange for advertisers in Luxembourg and internationally. The Google Partner status and the five Google Ads certifications attest to it.

Web marketing agency or digital advertising agency: what is the difference?

None in practice: "web marketing agency" describes the same work, designing and running campaigns on Google, Microsoft, Meta, LinkedIn or TikTok to generate enquiries and sales. AIxH is a web marketing agency in Luxembourg in the sense most advertisers mean, with a Digital advertising service that runs the campaigns and an SEO service for organic traffic.

Which advertising platforms does AIxH manage?

AIxH manages Google Ads (Search, Display, Demand Gen, Performance Max), Meta Ads (Facebook, Instagram), LinkedIn Ads, TikTok Ads, Microsoft Ads and native advertising. The mix is chosen according to your target audience and your market, in Luxembourg and internationally.

Does AIxH also do SEO and GSO?

Yes, through two dedicated services run in step with your advertising campaigns: SEO for the organic foundations and the traffic that comes from Google, and GEO for visibility in the answers of ChatGPT, Gemini or Perplexity.

How long before results show?

Advertising campaigns produce their first usable data within the first few weeks, then improve by iteration: the lessons of each cycle feed the next, and the cost per lead falls as the targeting sharpens.

How does AIxH measure campaign results?

AIxH measures results with GA4, each platform's conversion tags and Looker Studio dashboards, complemented by multi-touch attribution. The indicators tracked are business KPIs: leads, cost per lead, cost per appointment, sales. Impressions and clicks are never the target.

What results has AIxH already achieved?

AIxH divided the cost per appointment of Primagaz France by three after taking over its campaigns in 2024 (Google Ads, Microsoft Ads and Meta Ads) and ran acquisition campaigns in more than 20 countries and 20 languages. The details of these assignments are on the Clients page.
