How to appear in Claude
Claude is the engine where the memory path weighs most and where there is no paid lane. Those two together make it the slowest to move and the most honest about who has substance.
How to appear in Gemini
Gemini plugs into the Google ecosystem, but the organic top 10 explains only 38% of citations in AI Overviews. Classic SEO as the entry ticket, schema and the Google listing, YouTube ahead of the citations, declared authorship, and why Gemini does not show up in Search Console.
How to appear in Meta AI

Why the AI called a vacuum cleaner an iron
ChatGPT recommended a Bosch vacuum cleaner and described it as an iron. We chased the cause down to the exact page it read, and it is there: twenty products in a list and not one of them declared as a product. The mechanism, the proof, and the fix.
