Our expertise

SEO and GEO: two levers for visibility, one strategy

SEO, the foundation of your visibility on Google

Search engine optimization (SEO) means optimizing your site's technical structure, content, and links so it ranks well in Google's search results. It's the foundation of qualified, lasting traffic, without relying solely on paid advertising. Unlike paid advertising, whose effect stops the moment the budget runs out, a well-ranked site keeps generating qualified traffic month after month: it's an asset that gains value over time rather than a recurring cost with nothing built up.

The future of search

GEO, the new frontier of AI search

GEO (Generative Engine Optimization) means optimizing your presence so it is understood, cited, and recommended by generative AI such as ChatGPT, Gemini, or Google's AI Overviews. More and more searches now go through these assistants instead of a classic list of links, so being visible there is becoming strategic. Through our partnership with Serpixa, we already build this approach into our strategies. Not preparing for this isn't neutral: a brand absent from AI-generated answers loses visibility at the exact moment a potential customer is looking for a recommendation, often before they even reach Google. Investing in GEO today means not having to close a hard-to-catch-up gap tomorrow.

Frequently asked questions

The answers to the questions we get asked most.

Every quote is free and tailored: pricing depends on your site's current state, competition on your target keywords, and the campaign length you choose (3, 6 or 12 months). We always start with a free audit before proposing a priced plan, see our Pricing page for the general ranges.

SEO is a gradual investment: early technical wins (indexation, error fixes) are often visible within weeks, but durable ranking gains on competitive keywords typically take 3 to 6 months, and up to 12 months in highly competitive markets. That's why we run 3, 6 or 12-month campaigns with transparent monthly tracking.

Before any paid campaign, we run a free analysis of your site and your main competitors: technical health, keywords you already rank for, missed opportunities. You get a clear, no-obligation report that becomes the basis for your quote.

Yes. Belgium is a multilingual market and search habits differ between Dutch, French and English speakers. We adapt every keyword strategy and every piece of content to the language and search culture of your audience, rather than simply translating.

Link building means earning links from other quality sites pointing to yours. Google reads these links as votes of trust: the more relevant, credible sources cite your site, the more authority, and ranking power, it builds.
