What you need

What do you need first?

Our four pillars

Four pillars to bring you customers: website, advertising, SEO and CRM

A website with no visitors is no use, and neither is a campaign pointing at a slow site. All four levers in one place, one pillar per screen.

03SEO and AI visibility

SEO and AI visibility

Be found on Google, and quoted by AI

Organic search, local SEO (Google Business Profile, customer reviews) and visibility in ChatGPT, Perplexity and Google AI Overviews.

A clear monthly retainer, a full audit, and a free tool to measure your starting point.

from €500 a month, six months minimum, AI visibility included in the method

04CRM and automatic follow-ups

CRM and automatic follow-ups

Every enquiry tracked, followed up and turned into a customer

We set up your CRM, whichever one it is (HubSpot, Salesforce, Pipedrive, Zoho, Brevo, Sellsy, Axonaut, monday CRM or the one you already have), with your website forms and your campaigns connected to it, and automatic follow-ups by email.

AI takes on the repetitive work: replying to quote requests that come in overnight, Google reviews, appointments, writing.

on request, fixed price for the set-up, monthly support optional

What is wrong, and the method

Three reasons to call us, one method to answer them

Businesses get in touch for one of these three situations. Whichever pillar is involved, we work in the same order, with a price and a deadline written down before we start.

What is holding you back

  1. Nobody can find you

    Your customers search on Google, on maps and now inside ChatGPT, and they land on your competitors. A well-ranked website, a Google profile that is kept up to date and a targeted campaign change that.

  2. Your website does not convert

    Visits, but few calls and few quote requests. A slow site, a hidden form or a vague offer: we rework the structure so that every visit leads somewhere.

  3. You lose time on repetitive work

    Quotes answered late at night, Google reviews left unanswered, follow-ups forgotten. We hand those jobs to AI, with your rules and your tone of voice, so the real decisions stay with you.

What we do, in order

  1. Day 1

    Step 1: Free consultation

    Thirty minutes with the founder to understand your business, your customers and what is getting in the way today.

  2. Week 1

    Step 2: A clear plan and quote

    A written action plan, a fixed price and a deadline, before you commit to anything.

  3. Within 2 weeks

    Step 3: Build

    We do the work, you sign off at each step. You always speak to the same person.

  4. Every month

    Step 4: Tracking and measurement

    Enquiries, calls, sales: we measure what counts and we adjust.

The founder of ConvertiLab, in his studio in Rueil-Malmaison
Bilel Bettaieb, founder

I started ConvertiLab for the tradespeople, shopkeepers and self-employed people who have no time to manage an agency. I do the review, the quote, the build and the follow-up myself, from Rueil-Malmaison.

I test every method on my own business: my follow-ups, my invoicing, my review tool MerciAvis and my campaigns all run on the tools I set up for you.

  • One person to talk to

    The person who answers the phone is the one who builds your website, runs your campaigns or sets up your CRM.

  • All four levers in one place

    Website, advertising, SEO and CRM designed together: your campaign leads to a fast site, your site feeds your Google profile, and every enquiry gets followed up.

  • A fixed price, written down before we start

    The quote states the price and the deadline. Payment can be spread, and there is no subscription.

Frequently asked questions

Your questions about our digital marketing agency in Paris and Rueil-Malmaison

What exactly does ConvertiLab do?

Four things, designed to work together: your website, your online advertising (Google, Meta, TikTok, Pinterest, LinkedIn), your visibility on Google and inside AI tools, and your CRM with automatic follow-ups, with AI taking on the repetitive work. You can come to us for just one of those four building blocks.

How much does a website cost?

Landing page €490, brochure site €890, redesign €690, e-commerce from €1,490, applications quoted on request. The price is fixed and written into the quote before we start: no surprise line at the end.

Can I pay in instalments?

Yes: brochure site from €39 a month over 24 months, landing page €45 a month over 12 months, redesign €30 a month over 24 months, e-commerce €65 a month over 24 months. This is a payment spread over time, not a subscription: once the last instalment is paid, you owe nothing more.

How long until my site is live?

A free mock-up within 48 hours, then the site delivered two weeks after you approve that mock-up. A landing page takes 5 to 7 days. For a shop or an application, the timeline is written into the quote.

Who actually works on my project?

The founder of the agency, based in Rueil-Malmaison. The person who answers your first call is the one who builds your site, runs your campaigns or sets up your CRM, from the quote to going live, and then through the follow-up.

What budget should I plan for online advertising?

Two lines: our management fee, quoted on request, and the media budget paid straight to the platform, from €500 a month per platform. The ad account is created in your name, so you keep the history and the data if we stop working together. No minimum term, though three months is sensible before reading any results.

Which platforms do you advertise on?

Google Ads for the people already searching for your trade, Meta Ads (Facebook and Instagram) to create demand, TikTok Ads for the under-35s, Pinterest Ads for interiors, weddings and fashion, LinkedIn Ads for business clients. At the diagnostic stage we tell you which ones make sense for you, and which ones do not.

When does SEO start to show results?

Allow three to six months for organic search, often less locally with a well-kept Google listing and a steady flow of reviews. SEO retainer from €500 a month, six months minimum, then month by month. Visibility inside AI tools (ChatGPT, Perplexity, Google AI Overviews) is built into the method, with no promise of ranking.

What does the CRM and automatic follow-ups pole include?

Setting up your CRM, on the tool of your choice (HubSpot, Salesforce, Pipedrive, Zoho CRM, Brevo, Sellsy, Axonaut or monday CRM, or the one you already use), connecting your forms and your campaigns to it, then automatic email follow-ups: a quote with no reply chased after three days, an appointment reminder the day before. AI, Anthropic's Claude, then takes on the repetitive work: answering quote requests that came in overnight, Google reviews, writing. A one-day diagnostic, a fixed price given within 24 hours, and your data stays with you.

Are you in Paris or in Rueil-Malmaison?

In Rueil-Malmaison (92), in Hauts-de-Seine, close to La Défense. We work in Paris and across the Paris region, on site or by video call, and we work remotely with clients all over France: a photographer in Caen, a charity in Wissembourg.

Do you handle the copy and the images?

Yes. We write the copy, optimised for Google, and we choose the images with you, starting from your own photos when you have them. You review and approve every page before it goes live.

Is the site mine once it is delivered?

Yes, entirely. The domain name is in your name, you hold every login, and you stay free to develop it with whoever you like, instalment plan included. Once the site is live, we remain reachable for fixes and further work.
