— SEO & GEO Audit

What we check on your website

Q: What is a llms.txt file?

The llms.txt file is an emerging standard that allows websites to provide a structured summary of their content to AI generative crawlers. It complements robots.txt but for AI agents, and can improve citation accuracy by ChatGPT, Claude or Perplexity.

Before any proposal, we put your website under the microscope. Here are the 43 checkpoints of our SEO & GEO audit — the exact method we apply for our clients, as an SEO agency in Liège and across Belgium.

07 — Frequently asked questions

SEO & GEO: your questions

Questions our Belgian and international clients ask before starting an SEO project.

What is the difference between SEO and GEO?

SEO (Search Engine Optimization) aims to improve your visibility in traditional search engines like Google. GEO (Generative Engine Optimization) refers to techniques that help you get cited by generative AI tools like ChatGPT, Perplexity or Claude. Both complement each other: good SEO strengthens your GEO, and vice versa.

How long does it take to see SEO results?

Initial technical improvements are visible within a few weeks. For stable rankings on competitive keywords like "SEO agency Liège", expect 3 to 6 months of consistent work. SEO is a long-term investment.

What is a llms.txt file?

The llms.txt file is an emerging standard (proposed by Jeremy Howard) that allows websites to provide a structured summary of their content to AI generative crawlers. It complements robots.txt but for AI agents, and can improve citation accuracy by ChatGPT, Claude or Perplexity.

Is local SEO important for a Belgian SME?

Absolutely. In Belgium, over 46% of Google searches have a local intent. A well-optimised Google Business Profile, regular reviews and NAP consistency can place you above better-funded competitors in local searches.
