More links to the organisation’s own website: for a large organisation, we measured 150 prompts in ChatGPT, Gemini and Claude in June and in September 2026. The share of answers with a link to its website rose from 69% to 81%. We achieved this through content optimisation, above all by putting the answer first and making the information on the pages more precise. For the mostly brand-related questions, the organisation was named first in 93% of answers. In GA4, sessions from AI sources from 1 January to 17 September were around 90% higher than in the same period of the previous year. How much of this is due to individual measures cannot be cleanly separated.
What the log files reveal: over ten days (August and September 2026), we counted almost 29,000 requests from ChatGPT-User, an average of around 2,900 a day, to be read as an upper limit, including all 100 pages with the most Google clicks. 15% of Claude’s requests ended on 404 pages because the model had invented URLs. A crawler run by a large platform operator kept loading the same files in a loop, including a single 32 MB image. Findings like these only show up in log files.
