Facebook and Instagram reach people who are not looking for you yet, in your area or by what interests them. As a Facebook Ads and Instagram Ads agency, we build your campaigns, prepare the creatives and follow one figure every month: the cost per enquiry.

Who it is for, and for what problem
Google Ads answers demand that already exists. Meta Ads creates it: it shows your business to people who were not looking for it. That works when the offer can be understood in one image, and when an enquiry is worth more than it costs.
Your customers live less than fifteen minutes away. Meta Ads shows them your shopfront or your menu before they go looking.
Beauty, hairdressing, interiors, photography, craft work: a twenty-second video explains what you do better than a text ad ever will.
Catalogue connected to the account, visitors brought back with the products they looked at: we follow the cost per order and the average basket.
New premises, a new service, a seasonal promotion: a campaign can tell a whole town about something new in a few days.
Based in Rueil-Malmaison (92), we work as a web agency in Paris and, remotely, anywhere in France.
What we see
The three problems we meet most often on a Meta Ads account we take over.
The Boost button pushes a post with no objective, no pixel and no form: you get likes, not enquiries.
The same image for three months, shown to the same people: Meta serves it less and less, and every enquiry costs more.
The enquiries sit inside the Meta app and are found three days later. Called back within the hour, a contact answers; a week later, they have chosen someone else.
What we put in place
A Meta campaign is built from the objective, not from the format. Management fee on request, media budget from 500 € a month, paid to Meta from your own account.
The most common objective for trades and practices: a qualified enquiry, not just a click.

The catalogue is connected to the account, products are shown to the right people, and visitors are brought back.

Our method
Five markers in time, each with a result you can check inside your own account.
Day 1
Thirty minutes, free: your business, your area, your average sale. Any existing Meta account audited. If advertising is unlikely to pay for itself, we say so.
Week 1
Within 24 hours: objective, budget, target cost per enquiry, management fee. Then the Business Manager in your name, the pixel, the form connected to the CRM, the first three creatives.
Weeks 2 to 4
Three creatives and two audiences side by side, on a capped budget. From the second week we read the first enquiries and switch off whatever brings none.
Months 2 and 3
New creatives before the old ones wear out, audiences adjusted, remarketing: all from the real figures, until the cost per enquiry settles.
Every month
Budget spent, enquiries received, cost per enquiry, best creative. We decide together: carry on, spend more, test a format or stop.
What you can check
Since 4 September 2026, ConvertiLab has been running its own Facebook and Instagram campaign at 36 € a day: three videos being tested, an instant form connected to our CRM, the cost per enquiry read every week. The settings that hold up on our own account are the ones we suggest for yours.
We do not publish client figures: a cost per enquiry depends on the trade, the area and the season. What we can do is work out an order of magnitude with you before the first euro is spent.
Running in France. The enquiries it brings in are visible in our own CRM.
Our Meta campaign, in plain terms
Launch date
4 September 2026, campaign still running.
Daily budget
36 € a day, paid to Meta, three videos being tested.
Enquiries in our CRM
Every form lands in Pipedrive and sets off our follow-ups.
We show you the Ads Manager and the CRM over video, without any client result figures.
If you cannot answer that, it is the first figure we work out together, free of charge.
Straight talk
A written quote before anything goes live, an account in your name, a one-page report every month. If the campaign has not found its cost per enquiry after three months, we will suggest stopping or changing platform.
The advertising pillar
We start with one platform, the one where your customers already are. If that is not Facebook and Instagram, here are the others.

FAQ
No. Both are run from the same account, Meta Ads Manager, with the same creatives and the same budget. We start on both, then the budget moves towards whichever brings enquiries at the better cost. Depending on the trade, that is often Facebook for local services and Instagram for businesses that sell through images.
A media budget of at least 500 € a month, paid straight to Meta from your own account. Below that, the algorithm does not have enough data to learn and the results stay random. Our management fee comes on top, quoted according to the creative work and the number of campaigns. Our own campaign runs on 36 € a day, a little over 1,000 € a month.
The first impressions arrive as soon as the ads are approved, usually the same day. From the second week we read the first enquiries and switch off whatever brings none. It then takes four to eight weeks of testing for the cost per enquiry to settle: that is why we suggest three months before judging a campaign.
We do. From your photos, your past work or simple footage shot on a phone, we prepare the images, the carousels and the short videos, with the text and the subtitles. You sign them off before anything goes live. If you already work with a photographer or a videographer, we adapt their files to the Meta formats.
The instant form opens inside Facebook or Instagram, fills itself in from the profile and brings more enquiries, sometimes less qualified: we add questions to sort them. A page on your website brings fewer enquiries, but more committed ones, and it feeds remarketing. We often start with the instant form, connected to your CRM, then test the page if your website converts well.
If your customers already type your trade into Google, with some urgency (emergency call-outs, locksmiths, solicitors, dentists), start with Google Ads: the demand already exists. If your offer is discovered through images, or speaks to one neighbourhood (restaurants, beauty, interiors, an opening), Meta Ads is often the stronger choice. We start with one platform and only move to the second once the first is paying.
Yes. The Business Manager, the ad account, the pixel, the audiences and the history are created in your name, with your login. We work as a partner, with an access you can withdraw at any time. If you stop, you keep everything.
No minimum term: you can pause or stop whenever you like, we simply suggest three months to judge. If you stop, we pause the campaigns or leave them running, as you prefer, then remove our partner access. The account, the pixel, the creatives and the history stay yours.
