About Catherine Gason, international SEO and AI visibility expert
Catherine Gason is an international marketing consultant and Fractional CMO specializing in multilingual growth systems. On this site she works as the practitioner: the person who shows how international and AI search actually behave, market by market.
Who is Catherine Gason?
Catherine Gason is an international SEO and AI visibility expert, international marketing consultant and Fractional CMO. She founded GasOn Marketing and created this specialist property, where the technical depth behind the strategy lives. She works as Fractional CMO or consultant for scale-up and mid-market companies, and advises larger organizations on international SEO, AI visibility and digital PR.
Is Catherine a consultant or a Fractional CMO?
Both, and the distinction is the engagement, not the person. As consultant she designs the international growth system above channels, agencies and reporting. As Fractional CMO she owns it part-time: the decisions, the coordination, the accountability across markets. The work is the same system; what changes is how much of it she carries.
What kind of company does Catherine work with?
Companies whose international expansion has outrun the marketing system beneath it. The core is B2B SaaS in the UK or US, usually in the $5–50M ARR range, scaling across Europe; alongside them, product, ecommerce and manufacturing businesses internationalizing across European markets. The common trigger is structural: activity rises across markets while growth does not.
What makes her different from a generalist SEO or agency?
She works at the architecture layer, not the task layer. A generalist SEO or agency is briefed inside one market and one channel. Catherine builds the international growth system that decides whether a brand’s pages are found, trusted and cited across markets, and whether agencies pulling in different directions add up to growth. The named frameworks behind that work are hers.
Does she work across languages and European markets?
Yes. European markets are the norm for Catherine, who works in English, French and Italian. Client conversations run in English; the systems she builds are multilingual, with cross-language entity architecture that keeps a brand recognizable from one market to the next. That architecture also shows how identity and demand behave in each.
How does Catherine charge: retainer, project or audit?
It depends on the engagement. A diagnostic audit is a fixed scope; ongoing direction runs as a Fractional CMO retainer; a defined rebuild runs as a project. The entry point is the audit; it establishes where the brand actually stands across search and AI answers before any commitment to a larger engagement.
