SEO and GEO Blog
This SEO blog, which also covers GEO, deals with a single question: how to stay visible when your customers search on Google and ask AI engines their questions. Every article starts from dated studies and official sources (Google Search Central, Pew Research Center, Ahrefs, academic research), gives figures with their link and ends with an action plan a small business, in the US or elsewhere, can apply without hiring a large agency.

The articles are written by Thierry Gustin, a GEO consultant based in Madrid who works remotely with US businesses and has worked in search since 2011, creator of Éclair CMS and of the open-source tools Arachnide SEO Spider and Vigie. They are updated when the sources change. Where a study is based on American users, such as the Pew Research Center analysis of how US adults click when Google shows an AI summary, the article says so, so you can judge how directly the numbers apply to your own market. Dates follow the US format, prices are quoted in euros, and every figure keeps its original source link, so you can check it yourself.
