FAQ

Questions about our Online Ads agency?

The essentials before launching your digital advertising: goals, channels (SEA/Social), budgets, management, automation and preparing for your first call.

Why invest in Online Advertising (digital advertising)?
+
To win new customers, become better known, and generate leads and sales. Advertising also lets you be visible very quickly (particularly when launching an offer), where SEO often takes several months. It’s an ideal lever to get off the ground fast and learn fast.
How does Paid complement SEO?
+
SEO is a durable but slower lever. Paid lets you be visible immediately on generic queries and test new offers, services or messages quickly with progressive budgets. You can validate a proposition (acquisition cost + volume) while SEO builds performance over the long run.
Can you reach prospects at every stage of the customer journey?
+
Yes. You can activate several objectives at once: conversion (e.g. Search/SEA “pure product”) and awareness (e.g. YouTube). On Meta/YouTube, you can also reach audiences who don’t know you yet but have an interest in your offer, then move them toward conversion.
How long until you know if a campaign is working?
+
Often very quickly. Paid’s real advantage is reactivity: a campaign can be adjusted (or paused) fast, and some accounts are steered several times a day depending on need (raising or cutting budgets, tweaking settings, and so on).
Do my campaigns need to run all the time? (always-on vs spikes)
+
Not necessarily. You can run always-on with a reasonable monthly budget, and scale up during key periods (launches, seasonality, sales, Black Friday…). Some clients double or triple (sometimes more) their budgets in certain months, depending on the news cycle and search volumes.
Is there a minimum budget to work with an agency on Online Advertising?
+
There’s no “universal” minimum, but one thing matters: the budget needs to be consistent with your goals. With very low budgets, the cost of support can quickly outweigh the media spend itself (e.g. a media budget of €250/month). In practice, we recommend a media budget large enough to learn and optimise (often starting around €1,500-2,000/month, depending on the case), then adjusting based on results.
Are results guaranteed with Online Advertising?
+
No: we work with a roadmap set at a given moment, and the platforms (and their algorithms) keep changing. Optimisation becomes genuinely reliable after a few weeks of data. Our approach: frame, launch, then iterate based on signals (costs, volumes, conversion quality).
Can you audit or coach us without taking over full campaign management?
+
Yes. Depending on your context, we can step in as an audit, partial support or coaching engagement, without necessarily taking over the whole operational side. The goal: give you a clear framework and actionable optimisations, matched to the level of autonomy you want.
Do you only work with SEA on Google?
+
No. We activate the engines and platforms that are relevant to your needs: Google Ads, Bing Ads, as well as other paid levers (Social, YouTube, and so on). The idea isn’t to “force” one channel, but to align the media mix with your goals and your audience.
Do you use AI in campaign optimisation?
+
Yes: AI is a tool to speed up certain optimisations, test faster and scale more efficiently, not a replacement. We define the strategy, steer the trade-offs, and use AI to support performance and the pace of iteration.
Do you offer advertising within AI engines (GEA)?
+
Yes. Generative Engine Advertising (GEA) is an emerging lever that lets your brand appear directly in the answers generated by ChatGPT, Gemini or Perplexity. We help you understand the available formats and build a first campaign strategy.
Is an agency still useful with automation (e.g. Performance Max)?
+
Yes. Even as platforms automate more and more, strategy stays decisive: structuring, goals, messaging, priorities, guardrails, reading results and making decisions. Experience across dozens of different cases helps make the right calls and avoid “blind” optimisations.
Why work with an agency rather than a freelancer?
+
Depending on your challenges, an agency brings a team and cross-disciplinary expertise, experience across multiple sectors, and regular exchanges with the platforms (e.g. status/partnerships). The goal: secure the strategy and speed up execution as complexity or ambitions grow.
What should I prepare before a first meeting with an agency?
+
To move faster: your goals, your markets, and if possible, access to the platforms you’re using (Google Ads, Meta, and so on). The idea is to frame the context quickly and identify a clear starting point for strategy and management.
