Cited by AI
ChatGPT, Gemini and AI Overviews draw on well-ranked pages: good SEO is the foundation of GEO.

Frequently asked questions
SEO: your questions
SEO (Search Engine Optimization) covers the actions that improve a website's position in the unpaid results of Google and Bing: the site's technical health, content that answers searches, links from other websites and, for a local business, a Google Business Profile and customer reviews. To go further, read our guide to the 8 SEO levers in 2026.
At JSANCHEZ, packages start at €290 excl. VAT per month for local SEO, €390 excl. VAT for national SEO and €590 excl. VAT for international SEO. The exact budget depends on your sector, the competition and the size of the website: the initial SEO audit is free.
The first gains generally appear within 3 to 6 months. Google Business Profile optimisation and technical fixes can work faster; highly competitive queries take longer.
No. No serious agency can guarantee a ranking: Google alone decides its rankings. We commit to a method, monthly actions and transparent tracking of your rankings, your traffic and your leads.
SEO works on Google's organic results, for the long term. SEA (Google Ads) buys immediate visibility in the form of ads. GEO aims to get AI tools such as ChatGPT, Gemini or Google's AI Overviews to cite your business. The three complement each other: see our GEO page.
It is an essential foundation, because AI tools rely heavily on well-ranked pages. To be cited, you also need content that answers questions directly, a consistent business identity across the web and structured data: that is the role of GEO.
Google Search Console, Google Analytics, Google Business Profile, Semrush, Ahrefs, Screaming Frog, Yooda Insight and Ubersuggest, complemented by AI tools for semantic analysis and competitive monitoring.
