What we fixed
Before we started, our page titles arrived after the body of the page for every crawler except Bing's. Brave, the search index Claude uses, had named our homepage “laup.ai wordmark” after a hidden logo description. On 25 September we moved the titles into the head where they belong, and rewrote most of them to say what the page is.
Once Brave could read our titles, it probably also learned which Norwegian pages had English twins, and our Norwegian pages disappeared from Claude: it got the English version instead. On 29 and 30 September we unpaired them, and the Norwegian pages came back.
Two weeks later
MeasuredEach fix is a card on our own board. When a card goes live it freezes the two weeks before as its baseline, and every nightly run since adds to the after side.

Share of all answers that name Laup, the two weeks before against the 13 nights since:
| Engine | Two weeks before | 13 nights after |
|---|---|---|
| Claude | 4.4% | 9.1% |
| Gemini | 2.6% | 7.9% |
| Copilot | 2.5% | 8.6% |
| ChatGPT | 14.4% | 14.7% |
Claude is the one we predicted, since Brave is the index it searches. Gemini and Copilot we expected to stay about flat, and they moved as much as Claude did.

We changed some front-page copy in the same two weeks, so not every point of that is titles. But before we started, Claude could not even see what our pages were called. Now it can, and it finds our Norwegian pages again.
ChatGPT
ChatGPT already named us more than the others, and it did not move. When it reads a laup.ai page it names Laup almost every time. The problem is that it mostly reads our homepage, and a better title does nothing for a page the engine rarely finds. That is the next thing we look at.
What we take from it
Check that your titles are in the head of the page, not streamed in after the body. If you have pages in two languages, check that the language tags don't make an engine swap your page for its twin. And submit the pages you change to Bing, Brave and Google Search Console instead of waiting for the crawlers. That is the end of the titles series.
The titles series: Claude thought our homepage was called “laup.ai wordmark”, one night later, renamed, not ranked higher, our Norwegian pages disappeared from Claude and Titles, they matter. More experiments on our own site are under How we work with our AI visibility.
