Know what to fix, what to measure and what to prioritize over the next 90 days

I am a freelance digital marketing consultant. I do not sell hours or open ended mandates: two services, each with a written scope, a price, a timeline and a list of what is not included.

My services

Two ways to work together, both framed in advance

Two is a deliberately short catalogue. Each one answers a specific situation, and if none matches yours, I will say so rather than force the format.

Organic Visibility Diagnostic 90 days: Google, content and AI

Know what to optimize, what to create, what to recycle and in which order to act. The problem is almost never producing more, it is knowing what to prioritize.

  • A clear diagnostic report
  • A reading of your SEO, content and AI maturity
  • Your strengths, gaps and priority opportunities

Your conversions measurable in 30 days, with GA4 and Google Tag Manager

Finally know what actually generates your sales and your leads. This service puts your marketing counters back in working order, with conversions tested one by one rather than assumed.

  • A clear diagnostic of the current setup
  • A measurement plan aligned with your business goals
  • A GA4 and GTM configuration or rebuild

Your challenges, my solutions

Every organization is unique. Your challenges deserve a reading, not a catalogue

Digital marketing cannot be improvised. Small business, non profit or institution, your strategy has to account for your real situation and your resources.

A website nobody finds

We prioritize content that matches real demand and accessible technical optimization, before any advertising spend.

Organic Visibility Diagnostic 90 days

Content sitting dormant

Webinars, PDFs, videos, old articles: many organizations have already produced what they need, without ever making it findable.

Organic Visibility Diagnostic 90 days

Numbers nobody trusts

Without clean tracking, your budget decisions rest on conversions that are missing or counted twice.

Measurable conversions with GA4 and GTM

Campaigns nobody dares to cut

When measurement is fuzzy, everything gets kept just in case. It is the quietest way to waste a budget.

A word about me

I am Guillaume Sebag, freelance digital marketing consultant

My aim: turn your digital challenges into clear decisions. Since 2014 I have worked in agencies, in house and freelance, across France, New Caledonia and Canada.

My mission

Deliver precise, actionable readings of digital marketing: search, content, measurement, tools and AI usage. A data driven approach, full transparency on what is included and what is not, and respect for each organization operational reality.

My vision

Build plans that reach business goals while staying realistic for the team that has to execute them. Working with organizations across many sectors in France, Canada and the French overseas territories gave me a sharp understanding of local dynamics.

Artificial intelligence

An AI may already be quoting you, and you have no idea

Since 22 July 2026, Google AI Overviews and AI Mode have been live in France. Search Console opened a dedicated generative AI report in early June 2026: it gives impressions inside AI answers, but neither clicks nor queries. In other words, you now know that you appear, you still do not know what it brings in. Measuring what exists beats measuring nothing at all.
