The problem

Why does Google send you no enquiries?

Three situations we find in almost every audit. Each one has a precise cause, and a fix inside our method.

  • You pay for every click, because organic brings nothing

    Your enquiries come from advertising or from word of mouth. The moment the budget stops, so does the phone. Google itself sends you nobody.

  • Content published, with no strategy and no keywords

    Articles written at random, service pages that all read the same, no precise search term targeted: Google has no idea what to rank you for.

  • A previous supplier, and reports nobody can read

    Thirty-page spreadsheets, rankings on words nobody types, and still not a single enquiry.

What we do

What does our SEO retainer include?

Five levers that reinforce one another, carried out in this order: the technical work first, because without it the best content stays invisible.

  • 01

    Technical work and speed

    A site Google can read, index and load quickly. This is the foundation: without it, the best content in the world stays invisible.

    • Title and description tags and heading structure on every key page
    • Speed, mobile display and Core Web Vitals fixed
    • Schema.org structured data, sitemap, robots.txt, indexing monitored
  • 02

    Content written every month

    Service pages and articles that answer the questions your customers actually type, read and approved by you before they go live.

    • Research into what your customers search for, in Paris, in the 92 or in your own town
    • One target page per important search term, structured as questions and answers
    • Copy written with your prices, your lead times and your real examples
  • 03

    Architecture and internal linking

    The links between your own pages pass authority from your strong pages to your weak ones and help Google make sense of your site.

    • Pillar pages and sub-pages linked to one another
    • Descriptive anchors, breadcrumbs, orphan pages removed
  • 04

    Inbound links earned properly

    Sites connected to your trade or your town talking about you: useful directories, partners, the local press, guest articles.

    • No links bought in bulk from link networks
    • Every link gained listed in the monthly report
  • 05

    Local and AI, included

    Your Google profile, your customer reviews and content that ChatGPT, Perplexity and Google AI Overviews can quote, at no extra cost.

    • Business profile completed and monitored, reviews collected with MerciAvis
    • An llms.txt file, AI crawlers allowed, FAQs marked up

Local SEO and visibility inside AI answers each have their own page: Google Business Profile and customer reviews on one side, being quoted by ChatGPT, Perplexity and Google AI Overviews on the other. For a full picture of your site before you start, see our full SEO audit.

Our method

How do we work on your SEO, month after month?

Five milestones, always in the same order, each with a result you can check in your Search Console.

  1. Day 1

    Étape 1 : A 30-minute call and a written quote

    Your business, your area, your customers, your current site. Within 24 hours, a written quote with the actions set out in detail and the monthly price. If SEO is not the right lever for you, we say so.

  2. Weeks 1 and 2

    Étape 2 : Full audit and target pages

    Technical, content, current rankings, competitors, Google profile, access for AI crawlers. Then the list of the search terms your customers type and the page on your site that must answer each one, agreed with you.

  3. Month 1

    Étape 3 : Technical fixes

    Tags, speed, mobile, internal linking, structured data, indexing. The foundation is laid before a single piece of content is written.

  4. Ongoing

    Étape 4 : Content, links, Google profile

    Service pages and articles written, reviewed with you and published. Inbound links earned properly. Google profile completed, reviews collected. Content structured for Google and for AI.

  5. Every month

    Étape 5 : A one-page report and adjustments

    Rankings, impressions, clicks and enquiries, taken from your Search Console, with the list of what was done. Whatever is not moving gets fixed, not hidden.

What you get

What you actually receive, every month

What belongs to you and what you can see, month after month.

  • A written audit and a prioritised plan

    What is holding you back, what pays off, and in which order. The document is yours, even if you carry on alone.

  • The list of your target search terms

    What your customers search for, the page that answers each one, and how they move month after month.

  • Content published every month

    Pages and articles written, reviewed with you and put online, tags and structured data included.

  • Inbound links, listed

    Every link gained, with its source and its date, in the report. Nothing bought in bulk.

  • A Google profile and reviews looked after

    Categories, photos, posts, replies to reviews, collection with MerciAvis: local SEO included.

  • A one-page monthly report

    Rankings, impressions, clicks and enquiries, taken from your Search Console. One page, not thirty.

If your current site cannot carry this work, we tell you during the audit. You can then ask for a free mock-up of a new site or a website redesign built for search.

What you can check

We apply this method to our own pages, and you can check it

No invented curves and no testimonials written for the occasion. On several competitive searches in Paris, our own site appears on page 1 or page 2 of Google: these are the methods described on this page, applied to ourselves.

We do not publish client figures: a ranking depends on the trade, the town, the competition and the age of the site. On the call, we show you our Search Console, with nothing made up.

Average positions recorded in our Search Console over 90 days (September 2026). They change constantly and say nothing about what your own site will do.

Three things to check

Without taking our word for it

  • Our own pages on Google

    Type these French searches into Google and look for convertilab.com in the results.

    • facebook ads paris
    • agence facebook paris
    • agence adwords paris
  • The free tool on this site

    It analyses any page in 60 seconds and returns a score with a PDF report.

  • This page itself

    One H1, questions as H2s, a marked-up FAQ, a breadcrumb trail: view the source code.

Typical agency or ConvertiLab

A typical SEO agency or ConvertiLab: what changes for you?

A typical SEO agency

  • A page one “guarantee” that Google never promised.
  • Twelve months signed up before the first result.
  • A thirty-page report on words nobody types.
  • Access and content held in the agency's name.

With ConvertiLab

  • No position promised: a commitment to the work and the fixes.
  • Six months minimum, then month by month.
  • A one-page report: rankings, impressions, clicks, enquiries.
  • Access, content, audit and Google profile in your name.

This table describes practices we often come across when taking over a site, not one agency in particular.

Our commitments

What we commit to, written into the quote

They do not promise a ranking, but a way of working.

  • A written quote before you commit

    The actions in detail, the monthly price and the length, in black and white, before we start.

  • No position promised

    We commit to the work and to the fixes, never to a ranking that Google alone decides.

  • Everything stays yours

    Access, audit, content, links, Google profile: in your name, with your logins, even if you stop.

  • An honest opinion before you sign

    If SEO is unlikely to pay off for you, we tell you on the first call.

How much does SEO cost with our agency?

Your questions

Your questions about search engine optimisation and our SEO retainer

How much does search engine optimisation cost?

Our retainer starts at €500 a month, six months minimum. The exact figure depends on how competitive your search terms are, how many pages need work and how much content has to be written each month. You receive a written quote, with the actions set out in detail, before you commit to anything. The full SEO audit can also be ordered on its own, on request.

How long before SEO shows results?

Technical fixes show up in your Search Console within a few weeks. Rankings usually start to move between the second and the third month. Allow three to six months for results you can measure: pages climbing, impressions rising, then visits and enquiries. Google takes time to reassess a site, and each action builds on the ones before it.

Why a minimum commitment of six months?

Because SEO stopped after two months produces almost nothing: the fixes, the content and the links add up, and Google needs several passes to take them into account. Six months is the shortest period over which the work can be judged honestly. After that you decide month by month, with no awkward notice period.

Do you guarantee page one, or first place on Google?

No, and nobody can: Google ranks the pages, and it changes its rules several times a year. An agency that guarantees you a position is selling you a promise it does not control. We commit to what we do control: the work carried out each month, honest reporting, and fixes when an action leads nowhere.

What does your work on inbound links (link building) involve?

We look for links from sites connected to your trade or your town: useful trade directories, partners, suppliers, the local press, guest articles. We do not buy links in bulk from link networks: Google spots them and penalises them. Every link gained is listed in your monthly report.

Who writes the content, and what do you need to provide?

We write the pages and the articles from a conversation with you about your trade, your customers and your prices. You read and approve each piece before it goes live: that is the only time we ask of you, roughly one read-through a month. Your photos, your figures and your real examples make the content more credible, for Google and for AI alike.

Does a ConvertiLab website already include SEO?

Every site we deliver comes with the SEO basics: title and description tags, heading structure, structured data, sitemap, robots.txt, speed and mobile display. Ongoing SEO, content and links every month, is this separate monthly retainer, because it calls for steady work over time.

What is the difference between the free tool and the full SEO audit?

The free tool analyses one page in 60 seconds (tags, speed, structured data, mobile, AI crawlers) and returns a score with a PDF report. The full audit, which we carry out ourselves, covers the whole site, your current rankings, your competitors and your Google profile, with a prioritised action plan. It is included when the retainer starts.

Do you only work in Paris and Rueil-Malmaison?

We are based in Rueil-Malmaison (92) and we work in Paris, in La Défense and across the Paris region. Search engine optimisation is done remotely: we also support shops, tradespeople and practices anywhere in France, with the same reports and the same single point of contact.
