## What we did

The bank appeared in fewer than one in five AI answers to Turkish credit card questions, while two digital banks were recommended in most of them.

1. **Tracked 80 Turkish credit card and loan prompts daily**
2. **Found 12 comparison sites that AI engines cited but that didn't list the bank's cards**
3. **Updated fee pages with clear, dated tables**
4. **Worked with PR to earn reviews on the most-cited sites**

Ossvy ran the bank's credit card and loan prompts in ChatGPT, Gemini and Perplexity every day and showed which comparison sites the engines cited. The team fixed the gaps in order of impact: listings on cited sites first, then its own fee pages.

## In their words

“We thought our brand was strong enough. Ossvy showed us that AI engines were reading comparison sites we had never looked at.” (Elif A., Digital Marketing Manager, Tarnwell Bank)
