--- title: "Case Studies: dated, sourced SEO and GEO results" description: "Case studies: citations recorded in ChatGPT and Claude, progress measured in Google Search Console. Dated, rounded figures with their sources stated." url: https://agence-seo.lu/en/case-studies/ updated: 2026-10-18 lang: en alternates: fr-LU: https://agence-seo.lu/projets/ en-LU: https://agence-seo.lu/en/case-studies/ --- # Dated results, with their source Five projects, figures recorded on a specific date and the tool that produced them: Google Search Console for Google Search, dated readings for AI assistants. Nothing is extrapolated. For each project, we only publish verifiable data, with its period and its source. Names are withheld for confidentiality. ## A consulting firm in Luxembourg ### Where the work started - **A production line for verified content**: Research, fact-checking, writing, publishing: every piece goes through all four steps before it goes live. - **A tracking dashboard**: Page indexing, Search Console data, citations recorded in AI assistants. ### The result on 18 October 2026 In the ChatGPT app, on a question asking for a provider recommendation in its core business, the firm is recommended in first position (reading of 18 October 2026). On a panel of 5 recommendation questions about its sector, each asked twice to Claude with web search on 18 October 2026, it is cited in 9 answers out of 10: 7 times among the first three providers cited, including 3 times in first position. - **1st**: position in ChatGPT's recommendation, reading of 18/10/2026 - **9 of 10**: Claude answers that cite it, panel of 18/10/2026 - **7 of 10**: answers where it is among the first three providers cited Assistant answers vary from one session to the next: what counts is the trend over several readings, not a single reading. ## A special-interest online magazine in France ### What we do Regular publication of verified articles (named sources, facts checked before publication), monitoring of topics that are rising in searches, internal linking between articles and page-by-page indexing checks. ### What Google Search Console shows From 18 September to 15 October 2026, compared with the previous 28 days (21 August to 17 September 2026): clicks rose from about 15 to nearly 60, impressions from about 950 to about 2,400. - **× 3.8**: clicks from Google, over 28 days - **× 2.5**: impressions in Google results - **28 days**: compared with the previous 28 days Source: Google Search Console, the site's property, final data retrieved on 18 October 2026. ## A Luxembourg editorial media outlet, launched in 2026 ### What we do Putting the site online, publishing articles based on institutional sources, structured data, sitemaps and indexing checks. ### What Google Search Console shows Its first 28 days online (21 August to 17 September 2026) compared with the next 28 (18 September to 15 October 2026): clicks rose from about 15 to nearly 30 and the click-through rate from about 1% to 2.7%. Impressions, on the other hand, fell from about 1,400 to about 1,100, after a peak in the first weeks. - **× 2**: clicks from Google, over 28 days - **2.7%**: click-through rate, against about 1% in the first month - **1,100**: impressions approximately, against 1,400 in the first month Source: Google Search Console, the site's property, final data retrieved on 18 October 2026. ## An online financial simulation tool in France ### What we do Structured data describing the tool, its frequently asked questions and how to use it; written answers to the questions users ask; the calculation method published with its limits; unverifiable reviews removed; a section of verified news articles, with a named author and a dedicated sitemap. ### What Google Search Console shows The 28 days before the rise (22 August to 18 September 2026) compared with the last 28 days of final data (19 September to 16 October 2026): clicks rose from about 20 to about 70, the click-through rate from about 0.4% to about 1.1%, and the average position improved from about 30 to about 23. Impressions grew more modestly, from about 5,500 to about 6,100. - **× 3.5**: clicks from Google, over 28 days - **1.1%**: click-through rate, against about 0.4% before - **+ 10%**: impressions in Google results Source: Google Search Console, the site's property, final data retrieved on 18 October 2026. ## An online women's fashion magazine in France ### What we put in place - **Google News eligibility**: Transparency pages (editorial policy, corrections, use of AI, funding), structured data for the publisher and the articles, a news sitemap. - **Topics chosen from data**: Search Console and analytics reviewed before writing on a topic, Google results analysed (angles, questions people ask) before drafting. - **Topic clusters**: One pillar page per theme and the articles that complement it, linked together. - **Images and indexing**: Visuals matched to search intent, produced in the formats Google asks for; indexing checked for every article after publication. - **On the GEO side**: Open access for AI assistant crawlers, marked-up questions and answers, the publisher's identity described in structured data. ### The results Google Search Console, last 28 days of final data (19 September to 16 October 2026) compared with the previous 28 days (22 August to 18 September 2026): clicks rose from 3 to about 840, impressions from about a hundred to more than 42,000. Over the last two weeks, the site has received about 15,000 impressions a week. In AI assistants, no citation has been recorded so far: it is the next indicator we are tracking. - **840**: clicks from Google approximately, against 3 in the previous 28 days - **42,000**: impressions approximately, against about a hundred - **28 days**: compared with the previous 28 days Source: Google Search Console, the site's property, final data retrieved on 18 October 2026. ## Readings, not promises. Every figure carries its period and its source. Comparisons use periods of the same length. Figures are rounded, never embellished: when an indicator falls, we say so. These results guarantee nothing for another website. They show the method we apply and how we report on it, as described on the [Method and audit](https://agence-seo.lu/en/method/) page. ## What we are asked about these projects. ### Why are the names not given? For confidentiality: no names, no website addresses, no screenshots. Naming a site would expose its audience data. The periods, the sources and the way readings are taken are public on this page. ### Where do the figures come from? For Google Search, from each site's Search Console, over 28-day periods compared with periods of the same length. For AI assistants, from dated readings: a question asked in the ChatGPT app, and a panel of questions asked several times to Claude with web search. Figures are rounded. ### Will you get the same results for my business? Nobody can guarantee that: rankings in Google and assistant answers depend on competition, on the starting condition of the site and on the model version. The free audit tells you what is realistic in your case. --- Request a free SEO and GEO audit: https://agence-seo.lu/en/contact/ or by email at contact@agence-seo.lu.
