For this case study, we deliberately show results rather than internal processes — because that is exactly what counts in GEO and LLM optimization: demonstrability. And current, up-to-date data at that — not old charts from before the AI era when SEO measures still consisted of many low-hanging fruits.<\/p>
SEO growth: robust visibility growth<\/h2>
The visibility index over the year shows no random hype, but a real trend change: after a longer sideways phase around ~0.4–0.5 (spring\/summer 2025), the curve picks up significantly from mid-2025 through to the 1.6+ range at the end of January 2026.<\/p>
Why this matters: visibility is the sum of rankings and relevance across many search queries. A value of 1.6+ in this niche, against established major competitors, is a significant SEO signal.<\/p> In the 5-year chart (Top-100 \/ Top-10) you can see the second hard signal: as of 02.02.2026, 19.86K keywords are in the Top-100, of which 9.87K are in the Top-10.<\/p> Context: Top-10 is the range where visibility is not just ‘there’, but click- and conversion-relevant. The fact that nearly half of the Top-100 set is already Top-10 is a genuine quality indicator.<\/p> In SISTRIX, the development of AI Overview integrations for Fischkaufhaus.de becomes visible. The trend shows strong growth through Q4\/2025 followed by a decline towards February 2026. Important: this drop should not automatically be evaluated negatively. Especially in the food\/fish environment, demand is highly seasonal (Christmas\/holidays = extreme peaks), which also changes the AI Overview delivery. The list shows 157 AI Overview keywords — a broad set of search queries where Fischkaufhaus URLs appear in AI Overview contexts. Based on the URLs, all four important content types are equally well represented:<\/p> The most exciting signal comes from LLM tracking via Peec AI: here it’s not just ‘who gets mentioned’ that is analyzed, but also how often domains are cited as sources.<\/p> In the evaluated prompts, Fischkaufhaus ranks at:<\/p> — on a par with market leader Deutsche See (19%, #2.1). Behind them follow Send-a-Fish (13%, #3.2), REWE (5%, #3.7), and FrischeParadies (5%, #4.5).<\/p> In the source report, a total of 2,360 citations were recorded. These are not just brand mentions, but how often the client’s content was referenced. Of these:<\/p> Here, Fischkaufhaus.de is above average compared to the major competitors — both in visibility and in the average number of citations, i.e. the sources that are named\/linked in the answer text.<\/p> In the prompt list (26 prompts, ‘Last 7 days’), you can see what this looks like in practice: several purchase-intent queries are at 100% visibility and position #1.0, e.g.:<\/p> In addition, there are other prompts that are also strong (frequently #1.7 to #2.0), e.g.<\/p> And this is what the queries look like live, using Gemini as an example from yesterday and today. Yesterday, the AI showed a list with our client at the top.<\/p> Today, the display looks different. Fischkaufhaus is listed under point 1, but below the competitor. Textually there are two nice click-boosters with phrases like ‘outstanding freshness’ and ‘sustainably sourced’.<\/p> And if I enter this prompt again tomorrow, the result may be different again. What matters is simply that through our SEO measures and targeted LLM optimizations, we increase the probability that the client appears for the desired prompts.<\/p> Fischkaufhaus.de shows how classic SEO growth metrics (visibility, top-10 keywords) and new GEO metrics (AI Overviews, LLM positions, citations) reinforce each other. They make authority measurable with the goal of information and conversion.<\/p> If you want to know how visible your brand really is in ChatGPT, Google AI Overviews, Gemini, Claude, or Perplexity (including citations & competitor comparison): we analyze this data-based and show you where the biggest levers for GEO are. What works for our clients and what makes us ourselves visible in AI responses — we are happy to implement the same for your project.
